TP5551/TP5552/TP5554
3PEAK
Ultra Low Noise, 3.5MHz, Zero Drift, RRIO Op-amps
Description
Features
The family of amplifier are single/dual/quad chopper
stabilized zero-drift operational amplifier optimize for
single or dual supply operation from 1.8V to 5.5V and
±0.9V to ±2.75V. TP555X features very low input offset
voltage and low noise with no 1/f noise corner down to
0.1Hz. The TP555X is designed to have ultra low offset
voltage and offset temperature drift, wide gain
bandwidth and rail-to-rail input/output swing while
minimizing power consumption.
Low Offset Voltage: 5μV(max)
Zero Drift: 0.05 µV/°C (max)
No 1/f Noise Corner Down to 0.1Hz
