New Family of Standard Amplifiers May 19, 2003 12:00 PM, Edited by PETech Staff 5/19/2003 Edited by PETech Staff New Family of Standard Amplifiers Fairchild Semiconductor International’s new family of power efficient CMOS amplifiers is specifically targeted for lower power applications. The LMV321 (single), LMV358 (dual), and LMV324 (quad) amplifiers consume a supply current of 120 microamps maximum at 2.7V and typically only 100 µA at 5V, using 20% less power than competitive devices.
With a gain bandwidth product of 1.4 MHz at 5V and slew rate of 1.5V/µs 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.

This family of amplifiers also provides rail-to-rail output and offers a supply voltage range of 2.5V to 5.5V (±1.25V to ±2.75V). The LMV321, LMV358 and LMV324 are pin compatible and direct replacements for the LMV3XX family from National Semiconductor, Texas Instruments, and Maxim.
