Fairchild Semiconductor International (South Portland, ME) introduced a family of power-efficient, CMOS amplifiers specifically targeted for lower power applications. The LMV321 (single), LMV358 (dual) and LMV324 (quad) amplifiers consume a supply current of 120µA maximum at 2.7V, and typically only 100µA at 5V. The new family of amplifiers also provide rail-to-rail output and offer a supply voltage range of 2.5V to 5.5V (±1.25V to ±2.75V).
With a gain bandwidth product of 1.4MHz at 5V and slew rate of 1.5V/µs at 5V, the amplifiers are suitable for portable applications such as cellular phones, PDAs, DSP interfaces, portable test equipment, digital still cameras, keyless entries
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.
The amplifiers add to Fairchild's portfolio of products targeted at low-power applications, including ultra-low-power LDOs,
switching regulators and MOSFETs, LEDs for backlighting, switches, and supervisory products such as temperature sensors and
reset generator circuits.
Pricing in 1,000-piece and 10,000-piece quantities is $0.25 and $0.18 each for the LMV321, respectively; $0.33 and $0.24 each for the LMV358; and $0.49 and $0.29 each for the LMV324. Available now, delivery lead time is two to four weeks for the LMV321 and LMV358, and two weeks lead-time for the LMV324.
