GENERAL DESCRIPTION

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 features the highest precision performance of any

op amp currently available. Offset voltage of the OP177 is only

10 µV max at room temperature and 20 µV max over the full

military temperature range of –55°C to +125°C. The ultralow

_OSof the OP177, combines with its exceptional offset voltage

drift (TCV_OS) of 0.1 µV/°C max, to eliminate the need for

external V_OSadjustment and increases system accuracy over

temperature.

The OP177 is offered in both the –55°C to +125°C military,

and the –40°C to +85°C extended industrial temperature

ranges. This product is available in 8-pin ceramic and epoxy

DIPs, as well as the space saving 8-pin Small-Outline (SO) and

the Leadless Chip Carrier (LCC) packages.

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

insure accurate performance in high closed-loop gain applications.
