AD5346/AD5347/AD5348 is a parallel interface octal voltage output 8-/10-/12-bit DAC with a voltage range from 2.5 V to 5.5 V. It features low power operation, guaranteed monotonicity, rail-to-rail output range, power-on reset, and other characteristics. It is suitable for applications such as portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, optical networking, automatic test equipment, mobile communications, programmable attenuators, and industrial process.
The AD5346/AD5347/AD5348 family provides octal DACs with 8‑, 10‑ and 12‑bit resolution respectively. They operate from a 2.5 V to 5.5 V supply, feature on‑chip output buffers for rail‑to‑rail operation, and support both buffered and unbuffered reference inputs. The devices include a simultaneous update pin (LDAC), an asynchronous clear pin, and a read‑back capability.
Typical applications include portable battery‑powered instruments, programmable voltage/current sources, optical networking, automatic test equipment, mobile communications, programmable attenuators, and industrial process control. Ordering guides and pin‑configuration tables are provided for both TSSOP and LFCSP packages.
