REF34-Q1 Low-Drift, Low-Power, Small-Footprint Series

Voltage References

1 Features

3 Description

•

AEC-Q100 qualified with the following results:

– Device temperature grade 1: –40°C to +125°C

ambient operating temperature

– Device HBM ESD classification level 2

– Device CDM ESD classification level C6

Initial accuracy: ±0.05% (maximum)

Temperature coefficient : 6 ppm/°C (maximum)

Operating temperature range: −40°C to +125°C

Output voltage options: 2.5V, 3.0V, 3.3V, 4.096V,

5.0V

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 µV_PP/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 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 standby.

•

Output current: ±10 mA

Low quiescent current: 95 μA (maximum)

Low shutdown mode current: 3 μA (maximum)

Wide input voltage: 12 V

Output 1/f noise (0.1 Hz to 10 Hz): 3.8 µV_PP/V

Excellent long-term stability 25 ppm/1000 hrs

Available in 6-pin and 5-Pin SOT-23 package and

8-pin MSOP package

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.
