3 Description

The OPA2993 and OPA4993 (OPAx993) are part of a family of high-voltage (32V), rail-to-rail input and output (RRIO) operational amplifiers. These devices offer excellent ac performance, including a wide unity gain bandwidth of 20MHz, and a high slew rate of 40V/μs, while only requiring a quiescent current of 400μA per channel.

These devices also offer excellent dc precision, low offset voltage (±1mV, maximum), and low offset drift (±3µV/°C, maximum) for high-voltage operation within the main input pair. These features make the OPAx993 a flexible, robust, and high-performance op amp for high-voltage industrial applications.

The OPAx993 family of op amps is available in small-size packages (such as SOT-23-8 and SOT-23-14), as well as standard packages (such as SOIC, and TSSOP), and is specified from –40°C to +125°C.
