OPA1654AIDR – TEXAS INSTRUMENTS

The Texas Instruments OPA1654AIDR is a single, precision, rail-to-rail input/output operational amplifier packaged in a space-saving 8-pin SOIC (small outline integrated circuit). Operating from a ±5V to ±18V supply, or a single 5V to 36V supply, it boasts a low input bias current of 10 pA maximum, contributing to exceptional accuracy in high-impedance applications. Its guaranteed input offset voltage of ±25µV ensures minimal drift, crucial for instrumentation and precision measurement circuits. The OPA1654AIDR features a unity-gain bandwidth of 1.1MHz and a slew rate of 1.4V/µs, making it suitable for moderately fast signal processing. Its low noise characteristics, with a voltage noise density of 1.9nV/√Hz, are beneficial in applications sensitive to noise interference. Common use cases include precision data acquisition systems, sensor signal conditioning, and low-noise instrumentation amplifiers. The device’s rail-to-rail capabilities allow for maximum dynamic range, while its low power consumption (typically 1.5mA) makes it ideal for battery-powered devices. The OPA1654AIDR’s advantages stem from its combination of precision, speed, and low power, making it a versatile choice for demanding analog signal processing applications.
