OPA2277 dual opamp hi speed lo noise amplifier DIP8 (4)
("P" version, which has better specs than the "AP" version)
by Burr Brown - Texas Instruments.
The OPA277 series precision op amps replace the industry standard OP-177 (OP-07, OP-77). They offer improved noise, wider output voltage swing, and are twice as fast with half the quiescent current. Features include ultra low 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.
OPA277 series op amps operate from ±2V to ±18V supplies with excellent performance. Unlike most op amps which are specified at only one supply voltage, the OPA277 series is specified for real-world applications; a single limit applies over the ±5V to ±15V supply range. High performance is maintained as the amplifiers swing to their specified limits. Because the initial offset voltage (±20µV max) is so low, user adjustment is usually not required. However, the single version (OPA277) provides external trim pins for special applications.
* ULTRA LOW OFFSET VOLTAGE: 10µV
