Quad-channel voltage and current output DAC provides 16-bit monotonic conversion for industrial analog output modules. Current outputs support 0 mA to 20 mA, 4 mA to 20 mA, and 0 mA to 24 mA ranges, while voltage outputs support 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V with overrange options. The device operates from up to +33 V and down to −26.4 V supplies and includes dynamic power control using a dc-to-dc boost converter. A 3-wire serial interface supports up to 30 MHz operation with SPI, QSPI, MICROWIRE, DSP, and microcontroller compatibility, with optional CRC-8 packet error checking and watchdog monitoring. The operating temperature range is −40°C to +105°C in a 64-lead LFCSP_VQ package.
