The OPA1641AID is a low-noise, low-distortion audio operational amplifier from Texas Instruments. The device features a low input bias current of 1.5nA, an ultra-low input voltage noise of 2.5nV/vHz, wide operating bandwidth up to 750kHz, and fast slew rate of 20V/µs. It also operates in a wide range of supply voltages from 3V to 16V, making it suitable for many applications.
The OPA1641AID is ideal for audio preamplifiers in professional audio equipment, active filters, and integrated circuit design for audio circuits. It has high rejection of common-mode signals, allowing for improved signal-to-noise performance. The OPA1641AID is also designed to be stable with capacitive loading, eliminating the need for compensation. Additionally, it is specified over the commercial temperature range of 0°C to 70°C.
