3 Description
The TLV904xD family includes single (TLV9041D)
and dual (TLV9042D) decompensated operational
amplifiers optimized for high efficiency in ultra-lowvoltage
applications. Operating from 1.2V to 5.5V
with rail-to-rail input and output swing, this family of
amplifiers deliver an exceptional gain bandwidth of
3.1MHz with only 16μA of quiescent current. The
TLV904xD enables high gain circuit configurations
and longevity in battery powered systems. The
availability of miniature packages also allow this
amplifier family to be used effectively in high density
board applications.
The TLV904xD is among the few amplifiers in the
industry capable of operating at supply voltages
as low as 1.2V, making the family well suited for
1.5V coin cell applications. The high gain bandwidth
eliminates the need for cascaded amplifier stages
in signal conditioning and filtering applications such
as field transmitters, motion detectors, and personal
electronics, simplifying design while reducing both
board space and overall system power consumption.
