Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & munity Reference Design OPA836, OPA2836 SLOS712I – JANUARY 2011 – REVISED OCTOBER 2016 OPAx836 Very-Low-Power, Rail-to-Rail Out, Negative Rail.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The OPA836 and OPA2836 devices (OPAx836) are single- and dual-channel, ultra-low power, rail-to-rail output, negative-rail input, voltage-feedback (VFB) operational amplifiers designed to operate over a power-supply range of 2.5 V to 5.5 V with a single supply, or ±1.25 V to ±2.75 V with a dual supply.

Consuming only 1 mA per channel and a unity-gain bandwidth of 205 MHz, these amplifiers set an industry-leading power-to-performance ratio for railto-rail amplifiers.

For battery-powered, portable applications where power is of key importance, the low-power consumption and high-frequency performance of the OPA836 and OPA2836 devices offer performanceversus-power capability that is not attainable in other devices.
