Analog Devices AD7943/AD7945/AD7948 12‑Bit Multiplying DACs Datasheet
The AD7943, AD7945 and AD7948 are fast 12‑bit current‑output DACs that operate from a single +5 V supply (normal mode) or +3.3 V to +5 V (biased mode). They are offered in DIP, SOP and SSOP packages and support serial, parallel or byte‑wide interfaces depending on the model.
Key specifications include 12‑bit resolution, ±0.5 LSB accuracy, low power consumption (≈5 µA IDD), fast 40 ns write strobe, 600 ns settling time, and low glitch (60 nV‑s). The datasheet also provides ordering information, absolute maximum ratings, pin configurations and timing diagrams for each device.
