FEATURES

Ultralow Offset Voltage: TA = +25 8C: 10 mV max –558C ≤ TA ≤ +125 8C: 20 mV max Outstanding Offset Voltage Drift: 0.1 mV/8C max Excellent Open-Loop Gain and Gain Linearity:

CMRR: 130 dB min PSRR: 120 dB min Low Supply Current: 2.0 mA max Fits Industry Standard Precision Op Amp Sockets (OP07/OP77) GENERAL DESCRIPTION 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 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 insure 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 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. Figure 1. Simplified Schematic
