AFE53004YBHR

AFE53004YBHR is a Texas Instruments 4-channel smart analog front end in a 16-ball DSBGA package of just 1.76 x 1.76 mm, built around one shared 10-bit ADC and four independently configurable channels. Each channel can work as a buffered voltage-output DAC with 1x, 1.5x, 2x, 3x or 4x gain, as a programmable current-output DAC spanning 25 µA to 250 µA, or as an input to the shared ADC; a comparator mode, force-sense output and predefined sine, triangular and sawtooth waveform generation round out the channel options. The interface auto-detects I2C, SPI or PMBus with a 50 MHz SPI ceiling, and user-programmable NVM plus a multifunction GPIO let the part run processor-less in small battery systems on 1.8 to 5.5 V over -40°C to +125°C. Selection advice: the orderable code is AFE53004YBHR - the W in the family name AFE53004W is not part of the ordering code, so quote the code exactly; for a 12-bit design the sibling AFE63004W is the step up. Parameters verified against Texas Instruments documentation.
