3 Description

The LMV821/LMV822/LMV824 op amps bring performance and economy to low voltage, low power systems. With a 5 MHz unity-gain frequency, at 2.7 V supply, and a 1.4 V/µs slew rate, the quiescent current is only 220 µA per amplifier. They provide rail to rail output (RRO) swing into 600 Ω load. The input common-mode voltage range includes ground and the maximum input offset voltage is 3.5 mV. They are also capable of easily driving large capacitive loads as indicated in the applications section.

The LMV821 single op amp is available in the tiny SC70-5 package, which is about half the size of the previous title holder, the SOT23-5. The LMV824NDGV is specified over the extended industrial temperature range and is in a TVSOP package.

Overall, the LMV821/LMV822/LMV824 devices are low voltage, low power and performance op amps designed for a wide range of applications at an economical price.
