Technical content

Dual/Quad 135µA, 14nV/√Hz, Rail-to-Rail Output Precision Op Amp The L T®6011/L T6012 op amps combine low noise and high precision input performance with low power consumption and rail-to-rail output swing. Input offset voltage is trimmed to less than 60µV . The low drift and excellent long-term stability guarantee a high ac- curacy over temperature and time. The 300pA maximum input bias current and 120dB minimum voltage gain further maintain this precision over operating conditions. The L T6011/L T6012 work on any power supply voltage from 2.7V to 36V and draw only 135µA of supply current on a 5V supply. The output swings to within 40mV of either supply rail, making the amplifier a good choice for low voltage single supply applications. The L T6011/L T6012 are specified at 5V and ±15V supplies and from –40°C to 85°C. The L T6011 (dual) is available in SO-8, MS8 and space saving 3mm × 3mm DFN pack- ages. The L T6012 (quad) is available in SO-14 and 16-pin SSOP packages.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The inputs are protected by back-to-back diodes and internal series resistors. If the differential input voltage exceeds 10V , the input current must be limited to less than 10mA. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum ratings. Note 4: Both the L T6011C/L T6012C and L T6011I/L T6012I are guaranteed functional over the operating temperature range of –40°C to 85°C. Note 5: The L T6011C/L T6012C are guaranteed to meet the specified performance from 0°C to 70°C and is designed, characterized and expected to meet specified performance from –40°C to 85°C but is not tested or QA sampled at these temperatures. The L T6011I/L T6012I are guaranteed to meet specified performance from –40°C to 85°C. Note 6: This parameter is not 100% tested. Note 7: Matching parameters are the difference between any two amplifiers. ∆CMRR and ∆PSRR are defined as follows: (1) CMRR and PSRR are measured in µV/V for the individual amplifiers. (2) The difference between matching amplifiers is calculated in µV/V . (3) The result is converted to dB. Note 8: The specifications for V OS, IB, and IOS depend on the grade and on the package.

Temperature differentials across the input connections can generate thermocouple voltages of 10’s of microvolts so the connections to the input leads should be short, close together and away from heat dissipating components. Air currents across the board can also generate temperature differentials. The extremely low input bias currents (20pA typical) al- low high accuracy to be maintained with high impedance sources and feedback resistors. The L T6011/L T6012 low input bias currents are obtained by a cancellation circuit on-chip. This causes the resulting I B+ and IB– to be uncor- related, as implied by the IOS specification being comparable to IB. Do not try to balance the input resistances in each input lead; instead keep the resistance at either input as low as possible for maximum accuracy. Leakage currents on the PC board can be higher than the input bias current. For example, 10GΩ of leakage between a 15V supply lead and an input lead will generate 1.5nA! Surround the input leads with a guard ring driven to the same potential as the input common mode to avoid exces- sive leakage in high impedance applications. Input Protection The L T6011/L T6012 feature on-chip back-to-back diodes between the input devices, along with 500Ω resistors in series with either input. This internal protection limits the input current to approximately 10mA (the maximum al- lowed) for a 10V differential input voltage. Use additional external series resistors to limit the input current to 10mA in applications where differential inputs of more than 10V are expected. For example, a 1k resistor in series with each input provides protection against 30V differential voltage. Input Common Mode Range The L T6011/L T6012 output is able to swing close to each power supply rail (rail-to-rail out), but the input stage is limited to operating between V – + 1V and V + – 1.2V . Exceeding this common mode range will cause the gain to drop to zero, however , no phase reversal will occur . Total Input Noise The L T6011/L T6012 amplifier contributes negligible noise to the system when driven by sensors (sources) with impedance between 20kΩ and 1MΩ. Throughout this range, total input noise is dominated by the 4kTR S noise of the source. If the source impedance is less than 20kΩ, the input voltage noise of the amplifier starts to contribute

impedance, starts to contribute and eventually dominate. impedance at the input, including the source impedance. as the amplifier is used in higher gain configurations.
