LTC1250 - Very Low Noise Zero-Drift Bridge Amplifier

The LTC1250 incorporates an improved output stage capable of driving 4.3V into a 1k load with a single 5V supply; it will swing±4.9V into 5k with ±5V supplies. The input common mode range includes ground with single power supply voltages above 12V. Supply current is 3mA with a ±5V supply, and overload recovery times from positive and negative saturation are 0.5ms and 1.5ms, respectively. The internal nulling clock is set at 5kHz for optimum low frequency noise and offset drift; no external connections are necessary.

The LTC1250 is available in a standard 8-pin plastic DIP and 8-pin SO packages.
