The AD7243 is a complete 12-bit, voltage output, digital-to-analog converter with output amplifier and Zener voltage reference. It features three selectable output ranges, a serial interface, and a 300 kHz DAC update rate. The product is suitable for applications such as process control, industrial automation, and digital signal processing systems.
The AD7243 is a complete 12‑bit voltage‑output digital‑to‑analog converter featuring an on‑chip voltage reference and an output amplifier. It offers selectable unipolar ranges (0 V‑5 V, 0 V‑10 V) and a bipolar ±5 V range, with gain set by an internal resistor network. The device uses a fast versatile serial interface that can operate up to 5 MHz, providing a DAC update rate of 300 kHz and supporting daisy‑chaining of multiple devices.
The datasheet includes functional block diagrams, pin‑out tables, timing characteristics, absolute maximum ratings, ordering information, and application notes for process control, industrial automation and DSP systems. Power‑supply decoupling recommendations and ESD precautions are also provided.
