16-bit dual DAC for ATE pin electronics
The MAX9979KCTK+D is a 16-bit dual-channel digital-to-analog converter (DAC) from Analog Devices, designed for precision analog output generation in automated test equipment (ATE), signal generation, and calibration systems. Its SPI data interface allows direct connection to most MCU or FPGA SPI peripherals with minimal glue logic — the serial clock and data lines handle the 16-bit word transfer per channel. The supply range spans -1.5V to 6.5V, accommodating bipolar output stages that swing below ground — common in ATE pin electronics where the DAC drives a level-setting node referenced to a negative rail.
Package and thermal board-fit
The exposed pad also provides a low-inductance ground return for the high-speed SPI interface and analog output stages — critical for maintaining 16-bit linearity at the full update rate. Surface-mount assembly with standard lead-free reflow profiles; the ROHS3 compliance means no RoHS exemption paperwork needed for EU or global BOMs.
