This document describes the features and characteristics of the AD5334/AD5335/AD5336/AD5344 series, which are quad voltage-output 8-/10-/12-bit DACs with a parallel interface.
The AD5334, AD5335, AD5336 and AD5344 are quad digital‑to‑analog converters (DACs) available in 8‑, 10‑ and 12‑bit versions. They operate from a single supply of 2.5 V to 5.5 V and feature low‑power operation, rail‑to‑rail output buffers, and selectable output ranges (0‑VREF or 0‑2 × VREF). Typical applications include portable battery‑powered instruments, programmable voltage/current sources, and industrial process control.
Key features include parallel interface with double‑buffered input logic, power‑down mode with currents as low as 80 nA, guaranteed monotonicity over all codes, and a temperature range of –40 °C to +105 °C. Detailed pin descriptions, functional block diagrams, and timing characteristics are provided for design integration.
| Supply Voltage Range | 2.5 V to 5.5 V |
|---|---|
| Resolution (AD5334) | 8 bits |
| Resolution (AD5335/AD5336) | 10 bits |
| Resolution (AD5344) | 12 bits |
| Power‑Down Current (3 V) | 80 nA |
| Output Voltage Range | 0‑VREF or 0‑2 × VREF |
The devices operate from a single supply voltage of 2.5 V to 5.5 V.
In power‑down mode the current is as low as 80 nA at 3 V.
The output can be configured for 0‑VREF or 0‑2 × VREF.
