PROGRAMMABLE VOLTAGE

REFERENCE APPLICATIONS

Micro Power Programmable Voltage

Reference

• Sensor Bias

FEATURES

• Variable DAC reference

• Linear Voltage Regulators

• DC/DC converters

• Voltage comparators

• Motor controllers

• 1.25V 1.0%, 20ppm/°C Tempco Reference

• Adjustable to ±0.25% Over the 0 to 1.25V Range

• 8 bit, 100kΩ XDCP on-chip

• Programmable Resolution of 4.9mV (255 steps)

• Extra Matched 100kΩ Resistor Available for

Increased Resolution Over a Smaller Range

• 2.7V to 5.5V Supply Range

• Amplifier biasing

DESCRIPTION

• 2-Wire Interface for Programming Reference

Setting

• Low Supply Current: 12µA in Normal Mode

• 8-pin TSSOP Package

• Programmable Reference

• NV Memory

The Intersil X60250 combines

temperature

compensated voltage reference with a Intersil Digitally

Controlled Potentiometer (XDCP) to provide a precision

adjustable reference with a range of 0.0V to 1.25V. The

device includes a serial bus interface to enable in-circuit

programming of the reference voltage.

• Pb-Free Plus Anneal Available (RoHS Compliant)

The XDCP contains a resistor chain with 255 taps to

provide 8 bits of digital adjustment to the reference

voltage. Non-volatile storage retains the digital wiper

setting, for permanent reference programming. An

additional matched 100kΩ resistor is available to

increase resolution of the output voltage while retaining

accuracy.
