– 0 V to 5 V
– 0 V to 12.5 V DAC Shutdown to User-Defined Level 12-Bit, 500-kSPS ADC with 16 Inputs:
– 16 Single-Ended or
Two Differential + 12 Single-Ended Two Remote Temperature Sensors:
– ±2°C Accuracy, –40°C to +150°C One Internal Temperature Sensor:
– ±2.5°C Accuracy, –40°C to +125°C Input Out-of-Range Alarms 2.5-V Internal Reference Eight General-Purpose Inputs and Outputs Configurable I2C-Compatible and SPI™
Interface with 5-V and 3-V Logic Power-Down Mode Wide Operating Temperature Range:
–40°C to +125°C Small Packages: 9-mm × 9-mm QFN-64, and
10-mm Г— 10-mm HTQFP-64 The AMC7812B 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 generalpurpose inputs and outputs (GPIOs), two remote
temperature sensor channels, and one local
temperature sensor channel. 1 2345 The device has an internal +2.5-V reference that can
configure the DAC output voltage to a range of either
0 V to +5 V or 0 V to +12.5 V. An external reference
can be used as well. Typical power dissipation is
95 mW. The AMC7812B is ideal for multichannel
applications where board space, size, and low power …
