The AD7245A/AD7248A is an enhanced 12‑bit voltage‑output DAC that integrates an output amplifier and a buried Zener reference on a single CMOS chip. It supports single‑supply (0‑5 V, 0‑10 V) and dual‑supply (±5 V) operation, with low power consumption (≈65 mW) and high linearity (±½ LSB). The device is available in DIP, SOIC and surface‑mount packages.
The datasheet provides detailed electrical specifications, pin descriptions, ordering information, and typical performance graphs such as settling time, noise spectral density and power‑supply rejection. It also includes absolute‑maximum ratings and recommended ESD precautions.
