Voltage Sample and Infinite Hold

General Description

Features

The DS4303 is a nonvolatile (NV) sample and infinite-

hold adjustable voltage reference. The reference volt-

age is programmed in-circuit during factory calibration/

programming. Programming the reference voltage,

♦ Precise Electronically Adjustable Voltage

Reference

♦ Enables Automated Factory Trimming of Devices

Needing Voltage Adjustment

, is as simple as applying the desired voltage on

OUT

and toggling the adjust pin (ADJ) to lock the V

OUT

♦ Can be Adjusted to Within 1mV

voltage level indefinitely, even if the device is power

cycled. The DS4303 replaces current cumbersome fac-

tory adjustment arrangements with a low-cost solution

that can be adjusted using automated techniques. In

addition, the DS4303 has the ability to be readjusted

after the unit has been fully assembled and tested. This

results in a much more flexible manufacturing arrange-

ment, lower inventory costs, and a quicker time-to-market.

♦ Wide Adjustable Output Voltage Range Within

300mV of the Supply Rails

♦ Low Temperature Coefficient

♦

1mA of Output-Current Drive

♦ NV Memory Stores the Voltage Indefinitely

♦ Output Short-Circuit Protection

♦ Low Cost
