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 range. For applications that require a different channel count, additional features, or converter resolutions, Texas Instruments offers a complete family of analog monitor and control (AMC) products.
