Product Summary

The op277gs is a precision operational amplifier, provides lower noise and higher speed with the same input offset and drift specifications as the OP07. Both parts have a 10μV offset, 0.2μV/℃ drift, and 1.8 million gain. Coupled with a low-voltage noise of 3.5nV/√Hz at 10Hz and a low 1/f noise corner frequency of 2.7Hz, the op277gs is optimized for accurate amplification of low-level signals. The op277gs features an 8MHz gain-bandwidth product and a 2.8V/μs is slew rate. The applications of the op277gs include low-noise dc amplifiers, microphone amplifiers, precision amplifiers, tape-head preamplifiers, thermocouple amplifiers, low-level signal processing medical instrumentation, strain-gauge amplifiers, high-accuracy data acquisition.
