DS4303R+T&R

The DS4303R+T&R is a non-volatile (NV) electronically programmable voltage reference in 5 pin SOT-23 package. The reference voltage is programmed in device during factory calibration. Programming the reference voltage (VOUT) is as simple as applying desired voltage on VIN and toggling adjust pin (ADJ) to lock VOUT voltage level indefinitely even if the device is power cycled. The voltage reference replaces current cumbersome factory adjustment arrangements with a low cost solution that can be adjusted using automated techniques. In addition, the voltage reference has the ability to be readjusted after the unit has been fully assembled and tested. This results in a much more flexible manufacturing arrangement, lower inventory costs and a quicker time-to-market. This device is typically used in threshold setting, offset nulling, bias adjusting, factory calibrated equipment and pressure bridges.
