DESCRIPTION
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 applicati...
