4-channel, smart AFE with 10-bit DAC, 10-bit ADC, IDAC and EEPROM

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.
