3 Description

Applications with only a positive supply voltage often

require additional stable voltage in the middle of the

analog-to-digital converter (ADC) input range to bias

input bipolar signals. The REF20xx provides a

bias the input bipolar signals.

The

REF20xx

offers

excellent

temperature

drift

(8 ppm/°C, max) and initial accuracy (0.05%) on both

quiescent current less than 430 µA. In addition, the

precision of 6 ppm/°C (max) across the temperature

range of –40°C to 85°C. All these features increase

the precision of the signal chain and decrease board

space, while reducing the cost of the system as

compared to a discrete solution. Extremely low

dropout voltage of only 10 mV allows operation from

very low input voltages, which can be very useful in

battery-operated systems.

excellent specifications and can sink and source

current equally well. Very good long-term stability and

low noise levels make these devices ideally-suited for

high-precision industrial applications.
