3 Description
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 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-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.
