7.1 Overview
The OPAx132 series of FET-input operational amplifiers provides highspeed and excellent dc performance. The
combination of high slew rate and wide bandwidth provide fast settling time. Single, dual, and quad versions
have identical specifications for maximum design flexibility. High performance grades are available in the single
and dual versions. All are ideal for general-purpose, audio, data acquisition and communications applications,
especially where high source impedance is encountered.

7.3 Feature Description
The OPAx132 series of JFET operational amplifiers combine low noise and wide bandwidth with precision and
low input bias current to make them the ideal choice for applications with a high source impedance. The
OPAx132 is unity-gain stable and features high slew rate (±20 V/μs) and wide bandwidth (8 MHz).
7.4 Device Functional Modes
The OPAx132 has a single functional mode and is operational when the power-supply voltage is greater than 5 V
(±2.5 V). The maximum power supply voltage for the OPAx132 is 36 V (±18 V).
