The DAC5578 (8 bit), DAC6578 (10 bit), and DAC7578 (12 bit) are low-power, voltage-output, octal channel, digital-to-analog converters (DACs). The devices are monolithic, provide good linearity,and minimize undesired code-to-code transient voltages (glitch).

The devices use a versatile, 2-wire serial interface that is I2C-compatible and operates at clock rates of up to 3.4MHz. Multiple devices can share the same bus.

The devices incorporate a power-on-reset (POR) circuit that ensures the DAC output powers up to zero-scale or midscale until a valid code is written to the device. These devices also contain a power-down feature, accessed through the serial interface, that reduces the current consumption of the devices to typically 0.42µA at 5V. Power consumption is typically 2.32mW at 3V, reducing to 0.68µW in power-down mode. The low power consumption and small footprint make these devices ideal for portable, battery-operated equipment.

The DAC5578, DAC6578, and DAC7578 are drop-in and functionally-compatible with the DAC7678. All devices are available in a 4x4, QFN-24 package and a TSSOP-16 package.

DAC7678EVM — DAC7678 評估模組

DAC7678EVM 旨在評估 DAC7678、DAC5578、DAC6578 或 DAC7578 數位類比轉換器。預設情況下，DAC7678EVM 已安裝 DAC7678，但可替換為任何其他引腳相容的元件。EVM 提供快速簡便的方式，用於評估低功耗、高解析度、8 至 12 位元系列數位類比轉換器 (DAC) 的功能與效能。雙線 I²C 介面接頭可輕鬆將 DAC 的 SCL 和 SDA 引腳連接至任何主機微處理器或基於 TI DSP 的系統。預設情況下，DAC7678EVM 設計為搭配板載外部參考使用，但可透過變更跳線設定並透過軟體啟用內部參考，輕鬆修改為使用 DAC 內部參考（適用於 (...)
