Technical content

30MHz, 10V/µs, Dual/Quad Rail-to-Rail Input and Output Precision Op Amps The L T®1630/L T1631 are dual/quad, rail-to-rail input and output op amps with a 30MHz gain-bandwidth product and a 10V/µs slew rate. The L T1630/L T1631 have excellent DC precision over the full range of operation. Input offset voltage is typically less than 150µV and the minimum open-loop gain of one million into a 10k load virtually eliminates all gain error . To maximize common mode rejection, the L T1630/L T1631 employ a patented trim technique for both input stages, one at the negative supply and the other at the positive supply, that gives a typical CMRR of 106dB over the full input range. The L T1630/L T1631 maintain their performance for supplies from 2.7V to 36V and are specified at 3V , 5V and ±15V supplies. The inputs can be driven beyond the supplies without damage or phase reversal of the output. The output delivers load currents in excess of 35mA. The L T1630 is available in 8-pin PDIP and SO packages with the standard dual op amp pinout. The L T1631 features the standard quad op amp configuration and is available in a 14-pin plastic SO package. These devices can be used as plug-in replacements for many standard op amps to improve input/output range and performance. Single Supply, 400kHz, 4th Order Butterworth Filter

Rail-to-Rail Input and Output The L T1630/L T1631 are fully functional for an input and output signal range from the negative supply to the posi- tive supply. Figure 1 shows a simplified schematic of the amplifier . The input stage consists of two differential am- plifiers, a PNP stage Q1/Q2 and an NPN stage Q3/Q4 that are active over different ranges of input common mode voltage. The PNP differential input pair is active for input common mode voltages V CM between the negative supply to approximately 1.4V below the positive supply. As VCM moves closer toward the positive supply, the transis- tor Q5 will steer the tail current I 1 to the current mirror Q6/Q7, activating the NPN differential pair and the PNP pair becomes inactive for the rest of the input common mode range up to the positive supply. The output is configured with a pair of complementary common emitter stages Q14/Q15 that enables the output to swing from rail to rail. These devices are fabricated on Linear Technology’s proprietary complementary bipolar process to ensure similar DC and AC characteristics. Ca- pacitors C1 and C2 form local feedback loops that lower the output impedance at high frequencies.

The offset voltage changes depending upon which input stage is active, and the maximum offset voltages are trimmed to less than 525µV . To maintain the precision characteristics of the amplifier , the change of V OS over the entire input common mode range (CMRR) is guaranteed to be less than 525µV on a single 5V supply. Input Bias Current The input bias current polarity depends on the input common mode voltage. When the PNP differential pair is active, the input bias currents flow out of the input pins. They flow in the opposite direction when the NPN input stage is active. The offset voltage error due to input bias currents can be minimized by equalizing the noninverting and inverting input source impedance. Output The outputs of the L T1630/L T1631 can deliver large load currents; the short-circuit current limit is 70mA. Take care to keep the junction temperature of the IC below the absolute maximum rating of 150°C (refer to the Power Dissipation section). The output of these amplifiers have reverse-biased diodes to each supply. If the output is forced beyond either supply, unlimited current will flow through these diodes. If the current is transient and limited to several hundred mA, no damage to the part will occur . Overdrive Protection To prevent the output from reversing polarity when the input voltage exceeds the power supplies, two pairs of crossing diodes D1 to D4 are employed. When the input voltage exceeds either power supply by approximately 700mV , D1/D2 or D3/D4 will turn on, forcing the output to the proper polarity. For this phase reversal protection to work properly, the input current must be limited to less than 5mA. If the amplifier is to be severely overdriven, an external resistor should be used to limit the overdrive current. The L T1630/L T1631’s input stages are protected against large differential input voltages by a pair of back-to-back diodes D5/D6. When a differential voltage of more than 0.7V is applied to the inputs, these diodes will turn on, preventing the emitter-base breakdown of the input transis- tors. The current in D5/D6 should be limited to less than 10mA. Internal 225Ω resistors R6 and R7 will limit the input current for differential input signals of 4.5V or less. For larger input levels, a resistor in series with either or both inputs should be used to limit the current. Worst-case differential input voltage usually occurs when the output is shorted to ground. In addition, the amplifier is protected against ESD strikes up to 3kV on all pins. Capacitive Load The L T1630/L T1631 are wideband amplifiers that can drive capacitive loads up to 200pF on ±15V supplies in a unity-gain configuration. On a 3V supply, the capacitive load should be kept to less than 100pF . When there is a need to drive larger capacitive loads, a resistor of 20Ω to 50Ω should be connected between the output and the capacitive load. The feedback should still be taken from the output so that the resistor isolates the capacitive load to ensure stability. Feedback Components The low input bias currents of the L T1630/L T1631 make it possible to use the high value feedback resistors to set the gain. However , care must be taken to ensure that the pole formed by the feedback resistors and the total capacitance at the inverting input does not degrade stability. For instance, the L T1630/L T1631 in a noninverting gain of 2, set with two 20k resistors, will probably oscillate with 10pF total input capacitance (5pF input capacitance and 5pF board capacitance). The amplifier has a 5MHz crossing frequency and a 52° phase margin at 6dB of gain. The feedback resistors and the total input capacitance form a pole at 1.6MHz that induces a phase shift of 72° at 5MHz! The solution is simple: either lower the value of the resistors or add a feedback capacitor of 10pF or more.
