The LTC1250’s bination of low front-end noise and DC precision makes it ideal for use with low impedance bridge transducers. The LTC1250 Features typical input noise of 0.75µVP-P from 0.1Hz to 10Hz, and 0.2µVP-P from 0.1Hz to 1Hz. The LTC1250 has DC to 1Hz noise of 0.35µVP-P, surpassing that of low noise bipolar parts including the OP-07, OP-77, and LT1012. The LTC1250 uses the industry-standard single op amp pinout, and requires no external ponents or nulling signals, allowing it to be a plug-in replacement for bipolar op amps. 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 mon mode range includes ground with single power supply voltages above 12V. Supply current is 3m A 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 5k Hz for optimum low frequency noise and offset drift; no external connections are necessary. The LTC1250 is available in standard 8-pin ceramic and plastic DIPs, as well as an 8-pin SOIC package.
