LTC1100 Precision, Zero-Drift Instrumentation Amplifier
U FEATURES DESCRIPTIO
■ Offset Voltage: 10µV Max The LTC®1100 is a high precision instrumentation amplifier ■ Offset Voltage Drift: 100nV/°C Max using zero-drift techniques to achieve outstanding DC ■ Bias Current: 65pA Max performance. The input DC offset is typically 1µV while ■ Offset Current: 65pA Max the DC offset drift is typically 5nV/°C; a very low bias ■ Gain Nonlinearity: 20ppm Max current of 65pA is also achieved. ■ Gain Error: ±0.075% Max The LTC1100 is self-contained; that is, it achieves a differ- ■ CMRR: 90dB ential gain of 100 without any external gain setting resistor ■ 0.1Hz to 10Hz Noise: 1.9µVP-P or trim pot. The gain linearity is 20ppm and the gain drift is ■ Single 5V Supply Operation 4ppm/°C. The LTC1100 operates from a single 5V supply ■ 8-Pin MiniDIP up to ±8V. The output typically swings 300mV from its power supply rails with a 10k load.
U APPLICATIO S
An optional external capacitor can be added from Pin 7 to ■ Thermocouple Amplifiers Pin 8 to tailor the device’s 18kHz bandwidth and to ■ Strain Gauge Amplifiers eliminate any unwanted noise pickup. ■ Differential to Single-Ended Converters The LTC1100 is also offered in a 16-pin surface mount package with selectable gains of 10 or 100. The LTC1100 is manufactured using Linear Technology’s enhanced LTCMOSTM silicon gate process. , LTC and LT are registered trademarks of Linear Technology Corporation.
