OPA2387 Ultra-High Precision, Zero-Drift, Low-Input-Bias-Current Op Amps

1 Features

3 Description

•

Ultra-low offset voltage: ±2 µV (maximum, tested)

Zero drift: ±0.003 µV/°C

The OPA387, OPA2387, and OPA4387 (OPAx387)

family of precision amplifiers offers state-of-the-art

performance. With zero-drift technology, the OPAx387

offset voltage and offset drift provide unparalleled

long-term stability. With a mere 570 µA of quiescent

current, the OPAx387 are able to achieve 5.7 MHz of

bandwidth, a broadband noise of 8.5 nV/√Hz, and a

1/f noise at 177 nV_PP. These specifications are crucial

to achieve extremely-high precision and no

degradation of linearity in 16-bit to 24-bit analog to

digital converters (ADCs). The OPAx387 feature flat

bias current over temperature; therefore, little to no

calibration is needed in high input impedance

applications over temperature.

Low-input bias current: 135 pA (maximum, tested)

Low noise: 8.5 nV√Hz at 1 kHz

No 1/f noise: 177 nV_PP(0.1 Hz to 10 Hz)

Common-mode input range ±100 mV beyond

supply rails

Gain bandwidth: 5.7 MHz

Quiescent current: 570 μA per amplifier

Single supply: 1.7 V to 5.5 V

•

Dual supply: ±0.85 V to ±2.75 V

EMI/RFI filtered inputs

2 Applications
