LMV321:Low power rail-to-rail input/output op-amp

The LMV321/358/324 family (single, dual, and quad) answers the need for low cost, general-purpose operational amplifiers. They operate with voltages as low as 2.7 V and feature both input and output rail-to-rail, 145 µA consumption current, and 1 MHz gain bandwidth product (GBP).

With such a low consumption and a sufficient GBP for many applications, these op amps are well suited for any kind of battery supplied and portable equipment application.

The LMV321 device is housed in the space-saving 5-pin SOT23-5 package, which simplifies board design. The SOT23-5 has two pinning configurations to answer all application requirements.

Key Features

  • Operating range from VCC = 2.7  to 6 V
  • Rail-to-rail input and output
  • Extended Vicm (VDD - 0.2 V to VCC + 0.2 V)
  • Low supply current (145 µA)
  • Gain bandwidth product (1 MHz)
  • ESD tolerance (2 kV)
