TEXAS INSTRUMENTS OPA277UA Precision Op-Amp, SOIC-8, 1MHz

The TEXAS INSTRUMENTS OPA277UA is a high-precision operational amplifier designed as a superior replacement for the industry-standard OP-177. It delivers enhanced performance with improved noise characteristics, a wider output voltage swing, and operates at twice the speed with half the quiescent current. This makes it an exceptionally efficient and accurate component for demanding electronic circuits.

Its key features include an ultralow offset voltage and drift, minimal bias current, and exceptionally high common-mode and power supply rejection ratios. Single, dual, and quad versions share identical specifications, offering maximum flexibility for your design needs. The OPA277UA operates reliably from ±2V to ±18V power supplies, with its performance rigorously specified across the real-world range of ±5V to ±15V, ensuring consistent operation under varying conditions.

Key Specifications & Features

• High Precision: Features an ultralow 10µV offset voltage and a minimal drift of ±0.1µV/°C, often eliminating the need for user adjustment.
• Excellent Signal Integrity: Boasts a high 134dB open-loop gain, 140dB common-mode rejection, and 130dB power supply rejection for clean, accurate amplification.
• Low Power Consumption: Consumes only 800µA of quiescent current per amplifier, supporting energy-efficient designs.
• Robust Design: Maintains high performance even as outputs swing to their specified limits.
• Green Product: Manufactured without antimony or bromine (no Sb/Br), aligning with environmental considerations.

Important Handling Note: This device has limited built-in ESD protection. During storage or handling, its leads should be shorted together or the component placed in conductive foam to prevent electrostatic damage to the MOS gates.
