Amplifiers drop in to cut power drain
A new family of power-efficient CMOS amplifiers is optimised for lower power applications
Fairchild Semiconductor has a new family of power-efficient CMOS amplifiers optimised for lower power applications. The LMV321 (single), LMV358 (dual) and LMV324 (quad) amplifiers consume a maximum supply current of 120uA at 2.7V and typically only 100uA at 5V, using 20% less power than competing devices.

This family of amplifiers also provides rail-to-rail output and offers a supply voltage range of 2.
to 5.5V (+/-1.25 to +/-2.75V).
Fairchild's new LMV321, LMV358 and LMV324 are pin compatible and direct replacements for the LMV3XX family from National Semiconductor, Texas Instruments and Maxim.
With a gain-bandwidth product of 1.4MHz at 5V and slew rate of 1.5V/us at 5V, these new CMOS amplifiers provide superior performance in portable applications such as cellular phones, PDAs, DSP interface, portable test equipment, digital still cameras, keyless entry and MP3 players.
Each amplifier is available in different package types for flexibility in a variety of designs.
The single LMV321 is available in a SOT23-5 or SC70-5, the dual LMV358 in an SOIC-8 or MSOP-8, and the quad LMV324 is available in an SOIC-14 or TSSOP-14 package.
