12-bit DAC with internal reference and SPI
The AD7233BNZ: This is a single-channel 12-bit DAC from the DACPORT® series, delivering a buffered voltage output through an R-2R ladder architecture. The ±0.5 LSB max INL and ±0.9 LSB max DNL mean the output stays within half a least-significant bit of the ideal transfer function — a fit for precision control loops where monotonicity matters. Settling time is 10 µs to within 1/2 LSB for a full-scale step, which sets the update rate ceiling for the downstream loop. The SPI data interface keeps pin count low — three wires (SCLK, SDIN, SYNC) plus the output and supplies. Analog supply range is ±10.8 V to ±16.5 V, which covers standard ±12 V and ±15 V rails.
Through-hole 8-DIP — board integration
The tube packaging is the standard delivery format for DIP devices.
RoHS compliance and documentation
The AD7233BNZ is ROHS3 compliant, meaning it meets the latest EU restriction on hazardous substances.
