Analog Devices Inc. AD5761 16 位多范围电压输出数模转换器
亚德诺半导体 AD5761/R 16 位多范围电压输出数模转换器（DAC）采用 4.75V-30V 的单电源或 -16.5V 到 0V VSS 和 4.75V-16.5V VDD。单通道的 AD5761/R 数模转换器集成了输出放大器和基准电压源缓冲器，以及上电/掉电控制电路，构成易于使用、通用的解决方案。AD5761/R 串行接口兼容 DSP 和微控制器接口标准，工作于高达 50MHz 的时钟速率。利用双重缓冲，数模转换器输出可实现异步更新。用户可选功能包括二进制补码或直接二进制输入编码，和通过控制寄存器中 RA[2:0] 位选择的输出范围。有八个可软件编程输出范围：0V 到 5V、0V 到 10V、0V 到 16V、0V 到 20V、±3V、±5V、±10V、−2.5V 到 +7.5V，5% 的超范围。AD5761R 版本具有低漂移 2.5V 基准 ±2ppm/°C（典型值）。 AD5761 数模转换器提供有保证的单调性，积分非线性(INL) 为 ±2LSB（最大值）、35nV/√Hz 的噪声及选定范围上 7.5μs 的建立时间。AD5761/R 多范围电压输出数模转换器在 −40°C 到 +125°C 的工业温度范围内工作，适用于工业自动化、仪表测量、数据采集、开闭环伺服控制、过程控制、可编程逻辑控制器。
Compatible with DSP and microcontroller interface standards, AD5761/R's serial interface operates at clock rates of up to 50MHz. Double buffering enables the asynchronous updating of the DAC output. User-selectable functions include twos complement or straight binary input coding and output range via the RA[2:0] bits in the control register. Eight software-programmable output ranges are available including 0V to 5V, 0V to 10V, 0V to 16V, 0V to 20V, ±3V, ±5V, ±10V, −2.5V to +7.5V with 5% over range. The AD5761R version provides a typical low drift 2.5V reference of ±2ppm/°C. AD5761/R DACs deliver guaranteed monotonicity, integral nonlinearity (INL) of ±2LSB maximum, 35nV/√Hz noise, and 7.5μs settling time on selected ranges.
Operating to specifications over the −40°C to +125°C industrial temperature range, the AD5761/R multiple range voltage output DACs are ideal for industrial automation, instrumentation, data acquisition, open-/closed-loop servo control, process control, and programmable logic controllers.
