OPA277UA Datasheet PDF - TI

●The OPA277UA is a High Precision Operational Amplifier replaces the industry standard OP-177. They offer improved noise, wider output voltage swing and are twice as fast with half the quiescent current. Features include ultralow offset voltage and drift, low bias current, high common-mode rejection and high power supply rejection. Single, dual and quad versions have identical specifications, for maximum design flexibility. The OPA277UA operational amplifier operates from ±2 to ±18V supplies with excellent performance. Unlike most operational amplifiers which are specified at only one supply voltage, the OPA277UA is specified for real-world applications, a single limit applies over the ±5 to ±15V supply range. High performance is maintained as the amplifiers swing to their specified limits. Because the initial offset voltage (±20µV maximum) is so low, user adjustment is usually not required. However, the single version (OPA277) provides external trim pins for special applications.

● 10µV Ultralow offset voltage
