TIOPA2132PA
Overview
The OPA2132PA is a high-performance dual JFET-input operational amplifier designed for applications requiring low noise and high precision. It features a wide supply range of +/-2.5V to +/-18V and is unity-gain stable, making it a versatile choice for high-speed analog signal processing. With its 8 MHz gain bandwidth and 20 V/us slew rate, it effectively handles fast-moving signals without phase inversion during overload conditions.
Why Choose This Part
This amplifier offers a superior combination of low noise (8 nV/rtHz) and high speed, which is rarely found in generic JFET op-amps. Its robust design includes overload protection and is specifically engineered to avoid phase inversion when the input common-mode range is exceeded. The 8-PDIP package is ideal for through-hole prototyping and provides excellent thermal performance for a dual-channel IC.
Applications
Key Specifications
Getting Started
For prototyping, the 8-PDIP package can be used directly in a standard breadboard or an 8-pin DIP socket. Ensure that bypass capacitors (typically 0.1 uF ceramic) are placed as close to the supply pins as possible to maintain stability at high slew rates. When designing PCB layouts, keep input traces short to minimize stray capacitance that could interact with the high-impedance JFET inputs.
