8-Lead SOIC (S-Suffix) GENERAL DESCRIPTION
This low noise, bipolar input operational amplifier is also a cost
effective alternative to chopper-stabilized amplifiers. The OP177
provides chopper-type performance without the usual problems
of high noise, low frequency chopper spikes, large physical size,
limited common-mode input voltage range, and bulky external
storage capacitors. The OP177 features one of the highest precision performance of
any operational amplifier currently available. Offset voltage of the
OP177 is only 25 μV maximum at room temperature. The ultralow
VOS of the OP177 combines with the exceptional offset voltage
drift (TCVOS) of 0.3 μV/°C maximum to eliminate the need for
external VOS adjustment and increases system accuracy over
temperature. The OP177 is offered in the -40°C to +85°C extended industrial
temperature ranges. This product is available in 8-lead PDIP, as
well as the space saving 8-lead SOIC. The OP177 open-loop gain of 12 V/μV is maintained over the full
±10 V output range. CMRR of 130 dB minimum, PSRR of 120 dB
minimum, and maximum supply current of 2 mA are just a few
examples of the excellent performance of this operational amplifier.
The combination of outstanding specifications of the OP177
ensures accurate performance in high close...
