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 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 offers enhanced specifications and pin-to-pin replacement for
LM4128 and LM4132.
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 is specified for the wide temperature range of −40°C to +125°C.
