GENERAL DESCRIPTION
The OP177 features the highest precision performance of any
op amp currently available. Offset voltage of the OP177 is only
25 µV max at room temperature. The ultralow V
OP177 combines with its exceptional offset voltage drift
(TCV
V
temperature.
The OP177’s open-loop gain of 12 V/µV is maintained over the
full ± 10 V output range. CMRR of 130 dB min, PSRR of
120 dB min, and maximum supply current of 2 mA are just a
few examples of the excellent performance of this operational
amplifier. The OP177’s combination of outstanding specifications
ensures accurate performance in high closed-loop gain applications.

This low noise bipolar input op amp 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 is offered in the –40°C to +85°C extended
industrial temperature ranges. This product is available in
8-pin epoxy DIPs, as well as the space saving 8-pin Small-
Outline (SO).

... ISOLATING LARGE CAPACITIVE LOADS The circuit in Figure 10 reduces maximum slew rate but allows driving capacitive loads of any size without instability. Because the 100 Ω resistor is inside the feedback loop, its effect on output impedance is reduced to insignificance by the high open- loop gain of the OP177. OP177 ...
