GENERAL DESCRIPTIONThe 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 VOS of the
OP177 combines with its exceptional offset voltage drift
(TCVOS) of 0.1 µV/°C max to eliminate the need for external
VOS adjustment and increases system accuracy over
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).

ELECTRICAL CHARACTERISTICS(@ VS = �15 V, TA = 25�C, unless otherwise noted.)
NOTESLong-Term Input Offset Voltage Stability refers to the averaged trend line of VOS versus time over extended periods after the first 30 days of operation. Excluding the
initial hour of operation, changes in VOS during the first 30 operating days are typically less than 2.0 µV.Sample tested.Guaranteed by design.Guaranteed by CMRR test condition.To ensure high open-loop gain throughout the ±10 V output range, AVO is tested at –10 V ≤ VO ≤ 0 V, 0 V ≤ VO ≤ +10 V, and –10 V ≤VO ≤ +10 V.
