Product Overview


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
  • ±0.1µV/°C Ultralow drift
  • 134dB High open-loop gain
  • 140dB High common-mode rejection
  • 130dB High power supply rejection
  • 1nA Maximum low bias current
  • 800µA Low quiescent current per amplifier
  • Green product and no Sb/Br

Applications

Power Management; Signal Processing; Audio; Test & Measurement
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
