The input DC offset is typically 1µV while the DC offset drift is typically 10n V/°C; a very low bias current of 50p A 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 300m V 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 18k Hz 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.
