The AD5337/AD5338/AD5339 are low power, dual voltage output, 2-wire interface, 8/10/12-bit DACs from Analog Devices.
The AD5337, AD5338 and AD5339 are dual‑channel buffered voltage‑output digital‑to‑analog converters offered in 8‑, 10‑ and 12‑bit versions. Each part is housed in an 8‑lead MSOP package and operates from a single 2.5 V to 5.5 V supply, making them suitable for portable battery‑powered instruments and programmable voltage sources.\n\nKey features include low power consumption (250 µA @ 3 V, 300 µA @ 5 V), a 2‑wire I²C‑compatible serial interface up to 400 kHz, rail‑to‑rail output swing, simultaneous dual‑channel update via LDAC, and three power‑down modes with sub‑µA quiescent current.
