Description
The LMV321 (single), LMV358 (dual), and LMV324 (quad) are a low cost, voltage feedback amplifiers that consume only 80 A of supply current per amplifier. The LMV3XX family is designed to operate from 2.7V ( 1.35V) to 5.5V ( 2.75V) supplies. The common mode voltage range extends below the negative rail and the output provides rail-to-rail performance. The LMV3XX family is designed on a CMOS process and provides 1.2MHz of bandwidth and 1.5V/ s of slew rate at a low supply voltage of 2.7V. The combination of low power, rail-to-rail performance, low voltage operation, and tiny package options make the LMV3XX family well suited for use in personal electronics equipment such as cellular handsets, pagers, PDAs, and other battery powered applications.
