The REF34-Q1 devices are low-temperature-drift
(6 ppm/°C), low-power, high-precision CMOS voltage references. The devices have ±0.05%
initial accuracy and low operating current with power consumption less than 95 µA. These devices
also offer very low output noise of 3.8 µVPP/V, which enable the devices to
maintain high signal integrity with high-resolution data converters and noise critical
Stability and system reliability are further improved by the low output-voltage
hysteresis of these devices and low long-term output voltage drift. Furthermore, the small
size and low operating current of the devices (95 µA) make them an excellent choise for
battery-powered applications. The REF34-Q1 features an enable pin that can set the device into
shutdown where it consumes a low stand by current (3 µA) to help with overall system power during
The REF34-Q1 family is specified for the wide temperature range of −40°C to +125°C.
