This design features a combination of precision input characteristics, wide bandwidth (2MHz) and high speed (0.8V/µs). The HA-5177 uses advanced matching techniques and laser trimming to produce low offset voltage (20 µV) and low offset voltage drift (0.2µV/oC). This design also features low voltage noise (9.0nV/√Hz), low current noise (1.2pA/√Hz), nanoamp input currents, and 120dB minimum gain. These outstanding features along with high CMRR (140dB) and high PSRR (135dB) make this unity gain stable amplifier ideal for high resolution data acquisition systems, precision integrators, and low level transducer amplifiers. The HA-5177 can be used as a direct replacement for the OP05, OP07, and OP77 while offering higher bandwidth and slew rate. See the HA-5177/883 data sheet for military grade parts and LCC package.

At ±5V supplies there is a slight degradation of slew rate and open loop gain. There is very little change in bias currents and offset voltage. The HA-5177 input stage has built in back-to-back protection diodes with series current limiting resistors. V+ 7 2 RLIMIT Offset Adjustment The following is the recommended V IO adjust configuration: +15V + RLIMIT 6 7 3 + 2 1 RP 8 6 3 4 V4 -15V The Bias currents will increase when a differential voltage of 0.7V is exceeded. The internal current limiting resistors sufficiently limit current therefore, no external resistors are required.
