DESCRIPTION
The LTC®1250 is a high performance, very low noise zero-drift 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.
