Product details

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.

Frequently asked questions

What is the closest functional second-source to AD7233BNZ?

The AD7233ANZ is the closest peer: same DACPORT® series, same 12-bit R-2R architecture, same SPI interface, same 8-DIP package, and same ±0.9 LSB max DNL. The key difference is INL — the AD7233BNZ guarantees ±0.5 LSB max, while the AD7233ANZ is ±1 LSB max. If the BOM requires the tighter INL, the AD7233BNZ is the correct fit; otherwise the AD7233ANZ is a drop-in alternative without rewiring.
