AD7564 is a device that integrates four 12-bit DACs with features such as four-quadrant multiplication, separate reference voltage inputs, single supply operation, low power consumption, and versatile interfaces.
The AD7564 integrates four independent 12‑bit DACs in a single package, each with its own reference input and current‑output configuration. It operates from a single +3.3 V to +5 V supply and offers simultaneous update, reset, and a versatile serial interface compatible with modern microprocessors.
The document provides detailed electrical characteristics, timing specifications, pin descriptions, and application hints for using the device in process control, portable instrumentation, and general‑purpose test equipment.
| Resolution | 12 bits |
|---|---|
| Number of DAC channels | 4 |
| Supply voltage range | 3 V to 5.5 V |
| Supply current (IDD) | 10 µA max |
| Output leakage current (IOUT1) | 10 nA max at +25 °C |

The AD7564 contains four independent 12‑bit DAC channels.
It can be powered from a single supply ranging from 3 V to 5.5 V (typical operation at +3.3 V to +5 V).
The device draws up to 10 µA supply current (IDD) under normal conditions.
Each channel provides 12‑bit resolution, with 1 LSB equal to VREF/212.
