1Hz to 10Hz Noise: 2µVP-P Single 5V Supply Operation 8-Pin MiniDIP The LTC1100 is a high precision instrumentation amplifier using chopper-stabilization techniques to achieve outstanding DC performance.
The input DC offset is typically 1µV while the DC offset drift is typically 10nV/°C; a very low bias current of 50pA is also achieved.
The LTC1100 is self-contained; that is, it achieves a differential gain of 100 without any external gain setting resistor or trim pot.
The gain linearity is 8ppm and the gain drift is 4ppm/°C.
The LTC1100 operates from a single 5V supply up to ± 8V.
The output typically swings 300mV from its power supply rails with a 10k load.
An optional external capacitor can be added from pin 7 to pin 8 to tailor the device’s 18kHz bandwidth and to eliminate any unwanted noise pickup.
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.
