TP5591 / TP5592 / TP5594
3PEAK
Features
Low Noise, 1.8V, 3.3MHz, RRIO, Zero Drift Op-amps
Description
The TP5591-2-4 amplifiers are single, dual and quad
chopper stabilized zero-drift operational amplifiers
optimized for single or dual supply operation from 1.8V
to 5.5V or ±0.9V to ±2.75V. The TP559x op-amps
feature very low input offset voltage and low noise with
1/f noise corner down to 0.1Hz. The TP559x amplifiers
are designed to have low offset voltage and offset
temperature drift, wide gain bandwidth and rail-to-rail
input and output swing while minimizing power
consumption.
LOW OFFSET VOLTAGE: 20 μV (Max)
ZERO DRIFT: 0.01 µV/°C
Ultra-low Noise:
-
-
-
Input Noise Voltage: 17 nV/√Hz at 1 kHz
0.1Hz to 10Hz Noise Voltage: 370 nVPP
1/f Noise Corner Down to 0.1Hz
3.3 MHz Bandwidth, 2.5 V/μs Slew Rate
Low Supply Current: 470 μA per Amplifier
Single-Supply Operation Down to +1.8V
Low Input Bias Current: 60 pA
The TP559x op-amps can provide low offset voltage
(20μV Max) and near-zero drift over time and
temperature with excellent CMRR and PSRR.
The TP5591 (single version) is available in SC70-5,
SOT23-5 and SO-8 packages. The TP5592 (dual version)
is offered in MSOP-8, SO-8 package. The TP5594 (quad
version) is available in TSSOP-14 and SO-14 package.
All versions are specified for operation from -40°C to
125°C .
High Gain, 127 dB High CMRR & PSRR
Overload Recovery Time: 35 μs
Rail-to-Rail Input and Output Swing
–40°C to 125°C Operation Range
