The DAC53608 and DAC43608 (DACx3608) are low-power, eight-channel, voltage-output, 10-bit or 8-bit digital-to-analog converters (DACs) respectively. The DACx3608 are specified monotonic by design across a wide power supply range from 1.8 V to 5.5 V. Using an external reference, the DACx3608 provides a full scale output voltage range of 1.8 V to 5.5 V while consuming 0.1-mA quiescent current per channel. The DACx3608 also includes per channel, user programmable, power down registers. These registers facilitate the DAC output buffers to start in a power down to 10K state and remain in this state until a power up command is issued to these output buffers.

Low quiescent current, wide power supply range, and per channel power down option makes DACx3608 ideal for low power, battery operated systems.

The devices communicate through the I2CTM interface. These devices support I2CTM standard mode (100 kbps), fast mode (400 kbps), and fast+ mode (1 Mbps). These devices also have a load DAC (LDAC) pin that allows simultaneous DAC updates.

The DACx3608 are available in small 3-mm × 3-mm, 16-pin WQFN package. The devices are fully specified over the extended industrial temperature range of –40°C to +125°C.

DAC53608EVM — DAC53608 10 位元 I2C 介面、緩衝電壓輸出 DAC 評估模組

DAC53608 評估模組 (EVM) 是一款易於使用的平台，用於評估 DAC53608 裝置的功能與性能。DAC53608 是一款 10 位元解析度的 8 通道緩衝低電壓輸出數位轉類比轉換器 (DAC)。此裝置提供高達 5V 的單極輸出電壓。

要使 DAC53608EVM 正常運作，還需要另外兩個電路板（可單獨訂購或搭配 DAC53608EVM 一起訂購）：BOOSTXL-DAC-PORT（用於 I2C 可程式化介面）和 MSP-EXP432E401Y MCU LaunchPad™ 開發套件。
