Description
The 3PEAK TP5531/2/4 low-power chopper stabilized
operational amplifiers provide input offset voltage
correction for very low offset and offset drift over time and
temperature. The devices operate with a single supply
voltage as low as 1.8V, while drawing 42μA per amplifier
of quiescent current with a gain bandwidth product of
350kHz. They are unity gain stable, have no 1/f noise,
have good Power Supply Rejection Ratio (PSRR) and
Common Mode Rejection Ratio (CMRR), and feature rail-
to-rail input and output swing.
The devices were designed using an advanced CMOS
process. The TP5531 (single version) is available in
SC70-5, SOT23-5 and SO-8 packages. The TP5532
(dual version) is offered in MSOP-8 and SO-8 package.
The TP5534 (quad version) is available in TSSOP-14 and
SOIC-14 package. All versions are specified for operation
from -40°C to 125°C .
