REF4132

SNAS794A –JUNE 2020–REVISED JUNE 2020

REF4132 Low-Drift, Low-Power, Small-Footprint Series Voltage Reference

1 Features

3 Description

The REF4132 device is a low temperature drift

(12 ppm/°C), low-power, high-precision CMOS

voltage reference, featuring ±0.05% initial accuracy,

low operating current with power consumption less

than 100μA. This device also offers very low output

noise of 15 μV_p-p/V, which enables its ability to

maintain high signal integrity with high-resolution data

converters in noise critical systems. Packaged in the

same SOT-23-5 package, REF4132 offers enhanced

specifications and pin-to-pin replacement for LM4128

and LM4132.

•

Voltage options: 2.5V, 3V, 3.3V, 4.096V, 5V

Initial accuracy: ±0.05% (maximum)

Low temperature coefficient :

•

–

A grade: 12 ppm/°C (maximum)

B grade: 30 ppm/°C (maximum)

•

Operating temperature range: −40°C to +125°C

Output current: ±10 mA

Low quiescent current: 100 μA (maximum)

Output 1/f noise (0.1 Hz to 10 Hz): 15 µV_PP/V

Excellent long-term stability 30 ppm/1000 hrs

Small footprint 5-pin SOT-23 package

Stability and system reliability are further improved by

the low output-voltage hysteresis of the device and

low long-term output voltage drift. Furthermore, the

small size and low operating current of the devices

(100 μA) can benefit portable and battery-powered

applications.

2 Applications

•

Data acquisition (DAQ)

PLC analog I/O modules

Field transmitters

REF4132 is specified for the wide temperature range

of −40°C to +125°C.
