The 10-bit AFE53004W and 12-bit AFE63004W (AFEx3004W) is a family of 4-channel, ultra-low power smart analog-front-end (AFE) devices. These devices feature one shared 10-bit analog-to-digital converter (ADC) with four independent channels. Each channel is independently configurable as a buffered voltage output digital-to-analog converter (DAC), programmable current output DAC, or an input to the shared ADC. The devices support Hi-Z power-down mode and Hi-Z output during power-off conditions. The analog outputs provide a force-sense option for use as a programmable comparator and current sink. The multifunction GPIO, function generation, and NVM enable these smart AFEs for processor-less applications and design reuse. These devices automatically detect I2C, PMBus, and SPI, and contain an internal reference.
The flexibility and the feature set of the smart AFE combined with tiny package and ultra low-operating power make these devices an excellent choice for small, battery-operated systems.
