The REF35EVM is a voltage reference evaluation module that demonstrates the REF35 integrated
circuit from Texas Instruments (TI).
The REF35 is an ultra-low power voltage reference with maximum 10 ppm/C temperature drift. The
REF35 is used primarily as a voltage reference for
low power data converters.
The REF35 is operable from VREF + VDO to 6 V. The REF35 uses only 1.4 μA
of current in active mode. This device comes with
an enable pin that allows the device to be set in
shutdown mode. The REF35 consumes only 0.1 μA of
current under the shutdown condition. REF35 is
available for a wide range of applications such as
flow transmitters, blood glucose monitors, servo
drive control modules, power quality analyzers,
fault indicators, oscilloscopes and process
analytics.
The REF35EVM features a user selectable-wide VIN input which uses a
TPS7B8150
linear regulator, allowing the user to widen the
input range to 40 V if desired. The VIN header is
connectable to an external power supply to provide
power. All of the REF35 input and output pins are
accessible for external connection via test
headers.
