OPA2132PA Description

The OPA2132PA from Texas Instruments is a high-performance, dual-channel JFET-input operational amplifier housed in an 8-pin DIP (Through Hole) package. Designed for precision audio and instrumentation applications, it combines ultra-low input bias current (5 pA) with a wide supply voltage range (5V to 36V), making it versatile for both single and dual-supply configurations. With a Gain Bandwidth Product (GBWP) of 8 MHz and a slew rate of 20V/µs, it delivers excellent dynamic performance for high-fidelity signal processing. The OPA2132PA is part of the OPAx132 series, known for its low noise and high-speed characteristics, making it ideal for demanding analog circuits.
