ABSOLUTE MAXIMUM RATINGS

AMC7823

SLAS453A – APRIL 2005 – REVISED OCTOBER 2005

The AMC7823 has an internal programmable reference (+2.5 V or +1.25 V), and an SPI serial interface. An

external reference can be used as well. Typical power dissipation is 100 mW. The analog input range is 0 V to

+5 V, and the analog output range is 0 V to +2.5 V or 0 V to +5 V. The AMC7823 is ideal for multichannel

applications where low power and small size are critical. The AMC7823 is available in a 40-lead QFN package

and is fully specified over the –40°C to +85°C temperature range.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated

circuits be handled with appropriate precautions. Failure to observe proper handling and installation

procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision

integrated circuits may be more susceptible to damage because very small parametric changes could

cause the device not to meet its published specifications.
