|TI ANNOUNCES VERY LOW 4PPM/C DRIFT, MICRO POWER VOLTAGE REFERENCE
FAMILY IN TINY|
DALLAS - Texas Instruments Incorporated (TI) today
introduced the REF32xx, a 4ppm/C temperature drift, high accuracy, voltage reference family from the company's
Burr-Brown product line. The micro-size SOT23-6 packaging and micro power consumption make this product family ideal
for portable and battery-operated applications, medical and test equipment, as well as data acquisition
The REF32xx features high output current of 10mA and is stable with
any capacitive load. To increase precision, the REF32xx uses force and sense pins that allow 4-wire "Kelvin"
connection measurement to effectively eliminate the impact of contact and trace resistance. Other features include
low quiescent current of 100uA, with a maximum quiescent current over temperature of only 135uA. Typically, the
quiescent current changes less than 2uA over the entire supply range.
The REF32xx can be operated from as
low as 1mV from the desired output level under the normal load conditions. When shut down, the output goes to a
high-impedance state and current is reduced to ~1uA.
All models in this product family are specified for the
wide industrial temperature range of -40C to 125C and offer low temperature drift
