描述
The LTC?1100 is a high precision instrumentation amplifier 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 differential 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?silicon gate process.
