TP2431/TP2432 /TP2434
1.6MHz Bandwidth, Micropower Low Noise Op-amps
Description
3PEAK
Features
The single TP2431, dual TP2432, and quad TP2434
operational amplifiers combine excellent DC accuracy
with Rail-to-Rail operation at the input and output. Since
the common-mode voltage extends from VCC to VEE,
the devices can operate from either a single supply
(2.2V to 5.5V) or split supplies (±1.1V to ±2.75V). Each
op amp requires less than 190μA of supply current.
Even with this low current, the op amps are capable of
driving a 1kΩ load, and the input-referred voltage noise
is only 13nV/√Hz. In addition, these op amps can drive
loads in excess of 2000pF.
Low Noise: 13nV/√Hz(f= 1kHz)
Supply Current: 190μA/ch
Offset Voltage: 1 mV (max)
Low THD+N: 0.0005%
Supply Range: 2.2V to 5.5V
Low Input Bias Current: 0.3pA Typical
EMIRR IN+: 85 dB( under 2.4GHz)
Slew Rate: 0.9 V/μs
Gain-bandwidth Product: 1.6MHz
Rail-to-Rail I/O
The precision performance of the TP2431/TP2432/
TP2434 combined with their wide input and output
dynamic range, low-voltage, single-supply operation,
and very low supply current, make them an ideal choice
for battery-operated equipment, industrial, and data
acquisition and control applications.
High Output Current: 70mA (1.0V Drop)
–40°C to 125°C Operation Range
Robust 7kV – HBM and 2kV – CDM ESD Rating
The TP2431 is single channel version available in 8-pin
SOP and 5-pin SOT23 packages. The TP2432 is dual
channel version available in 8-pin SOP and MSOP
packages. The TP2434 is quad channel version
available in 14-pin SOP and TSSOP packages.
