AD5763 is a 16-bit high precision dual channel analog digital converter produced by Analog Devices (ADI). The product can be programmed to output in the range of ±4.096V, ±4.201V or ±4.311V, with a maximum INL error of ±1LSB and a maximum DNL error of ±1LSB. The product has low noise, 10μs maximum settling time, integrated reference buffers, on-chip temperature sensor, power-up/brownout output control, programmable short-circuit protection, simultaneous updating via LDAC, asynchronous clear to zero code, digital offset and gain adjustment, logic output control pins, and DSP/microcontroller compatible serial interface. The product's temperature range is -40℃ to +105℃, and it uses iCMOS® technology.
The AD5763 is a dual, 16‑bit, serial‑input, bipolar voltage‑output DAC that operates from a supply of 4.75 V to 5.25 V. It offers programmable output ranges (+4.311 V, +4.201 V, +4.096 V), low noise (70 nV/√Hz), and integrated reference buffers, making it suitable for industrial automation, test equipment, and high‑accuracy instrumentation.
The datasheet provides detailed specifications such as resolution, INL/DNL, output voltage ranges, timing characteristics, and absolute maximum ratings. It also includes functional block diagrams, pin descriptions, layout guidelines, and ordering information for the 32‑lead TQFP package.
