Выписка из документа ↓LTC1250 Very Low Noise Zero-Drift Bridge Amplifier FEATURES DESCRIPTIO Very Low Noise: 0.75µVP-P Typ, 0.1Hz to 10Hz DC to 1Hz Noise Lower Than OP-07 Full Output Swing into 1k Load Offset Voltage: 10µV Max Offset Voltage Drift: 50nV/°C Max Common Mode Rejection Ratio: 110dB Min Power Supply Rejection Ratio: 115dB Min No External Components Required Pin Compatible with Standard 8-Pin Op Amps Available in Standard 8-Pin Plastic DIP and 8-Pin SO Packages The LTC®1250 is a high performance, very low noise zerodrift operational amplifier. The LTC1250's combination 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 components 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 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.
