REF3450SQDBVRQ1

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 systems.
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 batterypowered 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 standby.
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.
