AD5346/AD5347/AD5348 is a low power, high performance, 8/10/12-bit parallel interface, 8 channel voltage output DAC.
The AD5346, AD5347 and AD5348 are octal digital‑to‑analog converters (DACs) offering 8‑, 10‑ and 12‑bit resolution respectively. They operate from a 2.5 V to 5.5 V supply and feature rail‑to‑rail output, buffered or unbuffered reference inputs, and simultaneous update via an LDAC pin.
The document provides detailed electrical specifications, timing diagrams, absolute maximum ratings, pin configuration tables for both TSSOP and LFCSP packages, and ordering guides for each part number. It also includes typical application information and recommended grounding and bypassing practices.
| Supply voltage range | 2.5 V to 5.5 V |
|---|---|
| Resolution | 8 bits (AD5346), 10 bits (AD5347), 12 bits (AD5348) |
| Relative accuracy | ±0.15 LSB (AD5346), +0.5 LSB (AD5347), +2 LSB (AD5348) |
| Power‑down current | 120 nA @ 3 V, 400 nA @ 5 V |
| Output current capability | 25 mA at Vop = 5 V, 16 mA at Voo = 3 V |

Both a 38‑lead TSSOP and a 40‑lead LFCSP (lead‑frame chip‑scale) package are offered.
Each part contains eight DAC channels (octal configuration).
The device can source up to 25 mA when Vop is 5 V.
