DESCRIPTION

Operational Amplifi ers in SOT-23 The L TC®2050 and L TC2050HV are zero-drift operational amplifi ers available in the 5- or 6-lead SOT-23 and SO-8 packages. The L TC2050 operates from a single 2.7V to 6V supply. The L TC2050HV operates on supplies from 2.7V to ±5.5V . The current consumption is 800μA and the versions in the 6-lead SOT-23 and SO-8 packages offer power shutdown (active low). The L TC2050, despite its miniature size, features uncom- promising DC performance. The typical input offset voltage and offset drift are 0.5μV and 10nV/°C. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and common mode rejection ratio (CMRR) of more than 130dB. The input common mode voltage ranges from the nega- tive supply up to typically 1V from the positive supply. The L TC2050 also has an enhanced output stage capable of driving loads as low as 2kΩ to both supply rails. The open-loop gain is typically 140dB. The L TC2050 also features a 1.5μV P-P DC to 10Hz noise and a 3MHz gain bandwidth product. n Maximum Offset Voltage of 3μV n Maximum Offset Voltage Drift of 30nV/°C n Noise: 1.5μV P-P (0.01Hz to 10Hz Typ) n Voltage Gain: 140dB (Typ) n PSRR: 130dB (Typ) n CMRR: 130dB (Typ) n Supply Current: 0.8mA (Typ) n Supply Operation: 2.7V to 6V (L TC2050) 2.7V to ±5.5V (L TC2050HV) n Extended Common Mode Input Range n Output Swings Rail-to-Rail n Input Overload Recovery Time: 2ms (Typ) n Operating Temperature Range: –40°C to 125°C n SOT-23 Package n Thermocouple Amplifi ers n Electronic Scales n Medical Instrumentation n Strain Gauge Amplifi ers n High Resolution Data Acquisition n DC Accurate RC Active Filters n Low Side Current Sense L, L T , L TC and L TM are registered trademarks of Linear Technology Corporation.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: These parameters are guaranteed by design. Thermocouple effects preclude measurements of these voltage levels during automated testing. Note 3: All versions of the L TC2050 are designed, characterized and expected to meet the extended temperature limits of – 40°C and 125°C. The L TC2050C/L TC2050HVC are guaranteed to meet the temperature limits of 0°C and 70°C. The L TC2050I/L TC2050HVI are guaranteed to meet the temperature limits of –40°C and 85°C. The L TC2050H/L TC2050HVH are guaranteed to meet the temperature limits of –40°C and 125°C. Note 4: The bias current measurement accuracy depends on the proximity of the supply bypass capacitor to the device under test, especially at ±5V supplies. Because of testing limitations on the placement of this bypass capacitor , the bias current at ±5V supplies is guaranteed by design to meet the data sheet limits, but tested to relaxed limits.

multiplied by the closed loop gain of the op amp. To reduce this form of clock feedthrough, use smaller valued gain setting resistors and minimize the source resistance at the input. If the resistance seen at the inputs is less than 10k, this form of clock feedthrough is less than 1μV RMS input referred at 7.5kHz, or less than the amount of residue clock feedthrough from the fi rst form described above. Placing a capacitor across the feedback resistor reduces either form of clock feedthrough by limiting the bandwidth of the closed loop gain. Input bias current is defi ned as the DC current into the input pins of the op amp. The same current spikes that cause the second form of clock feedthrough described above, when averaged, dominate the DC input bias current of the op amp below 70°C. At temperatures above 70°C, the leakage of the ESD protection diodes on the inputs increases the input bias currents of both inputs in the positive direction, while the current caused by the charge injection stays rela- tively constant. At elevated temperatures (above 85°C) the leakage current begins to dominate and both the negative and positive pin’s input bias currents are in the positive direction (into the pins). Input Pins, ESD Sensitivity ESD voltages above 700V on the input pins of the op amp will cause the input bias currents to increase (more DC current into the pins). At these voltages, it is possible to damage the device to a point where the input bias current exceeds the maximums specifi ed in this data sheet. Shutdown The L TC2050 includes a shutdown pin in the 6-lead SOT-23 and the SO-8 version. When this active low pin is high or allowed to fl oat, the device operates normally. When the shutdown pin is pulled low, the device enters shutdown mode; supply current drops to 3μA, all clocking stops, and both inputs and output assume a high impedance state. Clock Feedthrough, Input Bias Current The L TC2050 uses auto-zeroing circuitry to achieve an almost zero DC offset over temperature, common mode voltage, and power supply voltage. The frequency of the clock used for auto-zeroing is typically 7.5kHz. The term clock feedthrough is broadly used to indicate visibility of this clock frequency in the op amp output spectrum. There are typically two types of clock feedthrough in auto zeroed op amps like the L TC2050. The fi rst form of clock feedthrough is caused by the settling of the internal sampling capacitor and is input referred; that is, it is multiplied by the closed loop gain of the op amp. This form of clock feedthrough is independent of the magnitude of the input source resistance or the magnitude of the gain setting resistors. The L TC2050 has a residue clock feedthrough of less then 1μV RMS input referred at 7.5kHz. The second form of clock feedthrough is caused by the small amount of charge injection occurring during the sampling and holding of the op amp’s input offset voltage. The current spikes are multiplied by the impedance seen at the input terminals of the op amp, appearing at the output APPLICATIONS INFORMATION
