Description
1.8V, 42μA, RRIO, Zero Drift Op-amps
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° to 125°

Note 2:
The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the
power supply, the input current should be limited to less than 10mA.
Note 3:
A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power
supply voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to
the package. The specified values are for short traces connected to the leads.
