The LTC1100 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 our enhanced LTCMOS™ silicon gate process.

In-Amp Diamond Plot Tool
The Diamond Plot Tool is a web application that generates a configuration-specific Output Voltage Range vs. Input Common-Mode Voltage graph, also known as the Diamond Plot, for Analog Devices Instrumentation Amplifiers. Based on user inputs such as supply voltage, gain, and input signal range, the tool detects saturation and recommends in-amps for which the input signal is in-range and the configuration is valid. Avoid saturation, find the best in-amp for your design, and save time.
