The LTC1100 is a high precision instrumentation ampli-
fier 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 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/°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.
