Overview
The TL972IDR is a dual operational amplifier from the TL97x family, produced by Texas Instruments. This component is designed to operate at voltages as low as ±1.35 V and features output rail-to-rail signal swing, making it particularly well-suited for portable and battery-supplied equipment. The TL972IDR is housed in an 8-pin SOIC (D) package, which is compact and convenient for board design. Its very low noise and low distortion characteristics make it ideal for applications such as audio preamplification.
