1100fc

The LTC

using zero-drift techniques to achieve outstanding DC

performance. The input DC offset is typically 1µV while

the DC offset drift is typically 5nV/°C; a very low bias

current of 65pA 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 20ppm 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 LTCMOS
