Texas Instruments  REF3425QDBVRQ1

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 devicesalso offer very low output noise of 3.8 µVPP/V, which enable the devices tomaintain high signal integrity with high-resolution data converters and noise criticalsystems.

Stability and system reliability are further improved by the low output-voltagehysteresis of these devices and low long-term output voltage drift. Furthermore, the smallsize and low operating current of the devices (95 µA) make them an excellent choise forbattery-powered applications. The REF34-Q1 features an enable pin that can set the device intoshutdown where it consumes a low stand by current (3 µA) to help with overall system power duringstandby.

The REF34-Q1 family is specified for the wide temperature range of −40°C to +125°C.Contact the TI sales representative for additional voltage options.
