The AD7398/AD7399 is a 12-bit/10-bit, serial-input quad DAC designed to operate from a single or dual power supply.
The AD7398 and AD7399 are quad, voltage‑output digital‑to‑analog converters offered by Analog Devices. They support single‑supply (3 V‑5 V) or dual‑supply (±5 V) operation and provide 12‑bit resolution for the AD7398 and 10‑bit resolution for the AD7399.
This datasheet includes a functional block diagram, feature list, electrical specifications, absolute‑maximum ratings, ordering information, pin configuration, control‑logic truth tables, terminology definitions, and typical performance graphs. It is intended for designers who need detailed electrical parameters and interface timing for integrating the DACs into their systems.
| Resolution (AD7398) | 12 bits |
|---|---|
| Resolution (AD7399) | 10 bits |
| Relative Accuracy (INL) | ±1.5 LSB max |
| Differential Nonlinearity (DNL) | ±1 LSB max |
| Supply Voltage Range (single supply) | 3 V to 5 V |
| Maximum Clock Frequency | 16.6 MHz |
They operate from a single supply of 3 V to 5 V or from dual supplies of ±5 V.
The serial interface can run up to 16.6 MHz.
Both devices provide four independent DAC channels.
