7 Detailed Description

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).
