High Precision Audio Power Amplifier IC OPA277UA For Precision Integrators

FEATURES

• Ultralow Offset Voltage: 10 μV
• Ultralow Drift: ±0.1 μV/°C
• High Open-Loop Gain: 134 dB
• High Common-Mode Rejection: 140 dB
• High Power Supply Rejection: 130 dB

• Low Bias Current: 1-nA maximum
• 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

DESCRIPTION

The OPAx277 series precision operational amplifiers replace 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 0.1 Hz to 10 Hz Noise power supply rejection. Single, dual, and quad versions have identical specifications, for maximum
design flexibility.
