TP5531/TP5532/TP5534
1.8V, 34μA, RRIO, Zero Drift Op-amps
Description
Features
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 34μA 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.
LOW OFFSET VOLTAGE: 10 μV (Max)
ZERO DRIFT: 0.008 µV/°C
0.1Hz to 10Hz Noise: 1.1 µVPP
Low Supply Current: 34µA per Amplifier
Bandwidth: 350 kHz
Slew Rate: 0.16 V/μs
High Gain, 130 dB High CMRR and PSRR
Rail-to-rail Input and Output Swing
–40°C to 125°C Operation Range
Small Packages: SC70 and SOT23 (TP5531)
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.
