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 评估模块
DAC7678EVM 旨在评估 DAC7678、DAC5578、DAC6578 或 DAC7578 数模转换器。默认情况下，DAC7678EVM 已安装 DAC7678，但可将其替换为任何其他引脚兼容器件。EVM 提供了一种快速简便的方法，用于评估低功耗、高分辨率、8 位至 12 位系列数模转换器 (DAC) 的功能和性能。两线制 I²C 接口接头用于将 DAC 的 SCL 和 SDA 引脚轻松连接到任何主机微处理器或基于 TI DSP 的系统。默认情况下，DAC7678EVM 设计为使用板载外部基准电压，但可以通过更改跳线设置并通过软件启用内部基准电压轻松改用 DAC 内部基准电压（适用于 (...)
