OPA4277PA General Description
The OPAx277 series of precision operational amplifiers replace the industry standard OP-177. The OPAx277 devices 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.
The OPAx277 operate from ±2-V to ±18-V supplies with excellent performance. Unlike most op amps that are specified at only one supply voltage, the OPAx277 series is specified for real-world applications; a single limit applies over the ±5-V (10-V) to ±15-V (30-V) supply range. High performance is maintained as the amplifiers swing to the specified limits. Because the initial offset voltage (±20 µV, maximum) is so low, user adjustment is usually not required. However, the single version (OPA277) provides external trim pins for special applications.
The OPAx277 are easy to use and free from phase inversion and the overload problems found in some other op amps. These devices are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions. Dual and quad versions feature completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
Features
- Ultra-low offset voltage: 10 µV

- Wide supply range: ±2 V to ±18 V
- Low quiescent current: 800 µA/amplifier
- Single, dual, and quad versions
- Replaces OP-07, OP-77, and OP-177
- For similar performance with ±40-V overvoltage protection, see the OPA2206
