DESCRIPTION (CONTINUED)
The AMC7823 has an internal programmable reference (+2.5V or +1.25V), and an SPI serial interface. An
external reference can be used as well. Typical power dissipation is 100mW. The analog input range is 0V to
+5V, and the analog output range is 0V to +2.5V or 0V to +5V. 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.
