OPA2277UA Description

Short technical summary and product information.

The Texas Instruments OPA2277UA is a high-precision operational amplifier designed to replace industry standards like the OP-177. It offers significant improvements in noise performance, wider output voltage swing, and enhanced speed with reduced quiescent current.

Key electrical characteristics include an ultra-low offset voltage of ±20µV maximum and an ultra-low offset voltage drift of ±0.1µV/°C. The device boasts a high open-loop gain of 134dB and high common-mode rejection (CMRR) of 140dB, along with a high power supply rejection ratio (PSRR) of 130dB. It operates over a wide supply voltage range of ±2V to ±18V, with specifications holding true across the ±5V to ±15V range.

Designed for ease of use, the OPA2277UA is stable in unity gain and free from phase inversion and overload issues. It is available in an 8-pin SOIC package and is suitable for surface mount applications. The operating temperature range is -40°C to +85°C, making it versatile for various environmental conditions.
