The REF4132-Q1 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 µVp-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-Q1 offers enhanced specifications and pin-to-pin replacement for LM4128-Q1 and LM4132-Q1.

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.

REF4132-Q1 is specified for the wide temperature range of −40°C to +125°C.
