精密 DAC (= DAC6311IDCK
采用 SC70 的低功率单通道 1.8V 至 5.5V、80mA、8 位、10 位和 12 位 DAC
说明
DAC6311（10位）是低功耗，单通道，电压输出数字至模拟转换器（DAC）。它们是由设计单调，并提供卓越的线性度，减少不想要的代码到代码的瞬态电压，同时提供在一个引脚兼容系列轻松升级。所有器件采用通用的3线串行接口，工作在高达50MHz的时钟速率，并与标准的SPI™，QSPI的™，MICROWIRE接口™兼容，数字信号处理器（DSP）的接口。低功耗串行接口与施密特触发输入：高达50MHz。片内输出缓冲放大器，轨到轨运行。扩展级温度范围-40 ° C至+125 ° C的，引脚兼容系列在小型6引脚SC70封装。DAC6311在便携式，电池供电仪器，过程控制，数字增益和失调调整和可编程的电压和电流源等方面有广泛的应用。 The DAC5311 (8-bit), DAC6311 (10-bit), and DAC7311 (12-bit) are low-power, single-channel, voltage output digital-to-analog converters (DAC). They are monotonic by design and provide excellent linearity and minimize undesired code-to-code transient voltages while offering an easy upgrade path within a pin-compatible family. All devices use a versatile, 3-wire serial interface that operates at clock rates of up to 50MHz and is compatible with standard SPI, QSPI, MICROWIRE, and digital signal processor (DSP) interfaces. All devices use an external power supply as a reference voltage to set the output range. The devices incorporate a power-on reset (POR) circuit that ensures the DAC output powers up at 0V and remains there until a valid write to the device occurs.
