DescriptionThe LTC1100 is a high precision instrumentation ampli-fier using chopper-stabilization techniques to achieve outstanding DC performance. The input DC offset is typically 1V while the DC offset drift is typically 10nV/;a very low bias current of 50pA is also achieved.
The LTC1100 is self-contained; that is, it achieves a differ-ential gain of 100 without any external gain setting resistor or trim pot. The gain linearity is 8ppm and the gain drift is 4ppm/.
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
TM enhanced LTCMOS silicon gate process.
