The document describes the features and characteristics of Analog Devices' LC2MOS 8-Bit DAC with Output Amplifiers AD7224, including single-chip design, low error, single or dual supply operation, etc.
The AD7224 is a precision 8‑bit voltage‑output digital‑to‑analog converter with on‑chip output amplifier and double‑buffered interface logic. It operates from either a single 15 V supply or dual supplies (±5 V to ±12.5 V) and provides low total unadjusted error (< 1 LSB) over a wide temperature range.
The device is supplied in standard 18‑pin DIP, 20‑lead SOIC, and ceramic packages, and includes specifications for input resistance, output drive capability, timing characteristics, and absolute maximum ratings. Application circuits for unipolar and bipolar output modes are provided.
