AD5379 is a 40-channel, 14-bit, parallel and serial input, bipolar voltage-output DAC with a system calibration function allowing user-programmable offset and gain.
The AD5379 is a high-performance digital-to-analog converter (DAC) featuring 40 channels in a single 108-lead CSPBGA package. It supports both parallel and 3-wire serial interfaces compatible with SPI, QSPI, MICROWIRE, and DSP standards, operating at clock speeds up to 50 MHz.
The device provides guaranteed monotonicity to 14 bits over a wide temperature range. Key features include buffered voltage outputs with a maximum span of 17.5 V, system calibration for programmable offset and gain, and simultaneous update capabilities via the LDAC pin.
