AD7224 is a 8-bit CMOS DAC with output amplifiers produced by Analog Devices. It can be operated with single or dual supplies, with a total unadjusted error of less than 1 LSB and an extended temperature range. It is compatible with double buffered inputs.
The AD7224 combines an 8‑bit voltage‑output DAC and a unity‑gain output amplifier on a single CMOS chip. It operates from a single +15 V supply or from dual supplies (VDD 11.4‑16.5 V, VSS –5 V) and provides a low total unadjusted error of less than 1 LSB over temperature.
The device features TTL/CMOS‑compatible logic inputs, double‑buffered registers for simultaneous updates, and a versatile pinout available in 18‑pin DIP, 20‑terminal SOIC, and PLCC packages. Detailed specifications cover resolution, accuracy, power consumption, switching times, and absolute maximum ratings.
| Resolution | 8 bits |
|---|---|
| Power Supply Range (dual) | VDD 11.4‑16.5 V, VSS –5 V |
| Power Supply Range (single) | VDD +15 V ±5 % |
| Typical Power Consumption | 35 mW (single supply) |
| Output Swing | +10 V across 2 kΩ load |
It can operate from a single +15 V supply or from dual supplies with VDD 11.4‑16.5 V and VSS –5 V.
All logic inputs are TTL and CMOS (5 V) level compatible.
The output amplifier can develop +10 V across a 2 kΩ load, corresponding to about 5 mA, and can tolerate short‑circuit currents up to 60 mA.
Typical power consumption is 35 mW when powered from a single supply.
