Maximum voltage operation must not exceed maximum junction temperature. Refer to Power Derating Curves chart.

Time required to initialize device. Power-On Time includes the time required to complete the internal automatic offset adjust. The DAC is then ready for peak acquisition.

OPERATING CHARACTERISTICS: valid throughout operating voltage and ambient temperature ranges using Allegro refer-

ence target 60-0, typical data applies at VCC = 12 V and TA = 25°C; unless otherwise specified
