7.1 Overview
The OPAx354-Q1 operational amplifiers are high-speed,150-V/μs, amplifiers making them excellent choices for
transimpedance applications. The devices are unity-gain stable and can operate on a single-supply voltage (2.5
V to 5.5 V), or a split-supply voltage (±1.25 V to ±2.75 V), making them highly versatile and easy to use. The
OPAx354-Q1 amplifiers are specified from 2.5 V to 5.5 V and over the automotive temperature range of –40°C to
125°C.

7.3 Feature Description
7.3.1 Operating Voltage
The specifications of the OPAx354-Q1 family of devices apply over a power-supply range of 2.5 V to 5.5 V
(±1.25 V to ±2.75 V). Supply voltages higher than 7.5 V (absolute maximum) can permanently damage the
amplifier.
The Typical Characteristics section of this data sheet show the parameters that vary over supply voltage or
temperature.
