The AMC7812 is a complete analog monitoring and
control solution that includes a 16-channel, 12-bit
analog-to-digital converter (ADC), twelve 12-bit
digital-to-analog converters (DACs), eight GPIOs, and
two remote/one local temperature sensor channels.
The AMC7812 has an internal reference of +2.5V that
can configure the DAC output voltage to a range of
either 0V to +5V or 0V to +12.5V. An external
reference can be used as well. Typical power
dissipation is 95mW. The AMC7812 is ideal for
multichannel applications where board space, size,
and low power are critical.
The AMC7812 is available in either a 64-lead QFN or
HTQFP-64 PowerPAD™ package and is fully
specified over the –40°C to +105°C temperature
For applications that require a different channel
count, additional features, or converter resolutions,
