AD5754AREZ-REEL7: 完全4通道、16 Bit、串行输入、单极/双极性电压输出数模转换器
The AD5724/AD5734/AD5754 are quad, 12-/14-/16-bit, serial input, voltage output digital-to-analog converters. They operate from single-supply voltages from +4.5 V up to +16.5 V or dual- supply voltages from ±4.5 V up to ±16.5 V. Nominal full-scale output range is software-selectable from +5 V, +10 V, +10.8 V, ±5 V, ±10 V, or ±10.8 V. Integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry are also provided.
The parts offer guaranteed monotonicity, integral nonlinearity (INL) of ±16 LSB maximum, low noise, and 10 μs maximum settling time.
The AD5724/AD5734/AD5754 use a serial interface that operates at clock rates up to 30 MHz and are compatible with DSP and microcontroller interface standards. Double buffering allows the simultaneous updating of all DACs. The input coding is user-selectable twos complement or offset binary for a bipolar output (depending on the state of Pin BIN/2sComp), and straight binary for a unipolar output. The asynchronous clear function clears all DAC registers to a user-selectable zero-scale or midscale output. The parts are available in a 24-lead TSSOP and offer guaranteed specifications over the −40°C to +85°C industrial temperature range.
AD5724/AD5734/AD5754是4通道12-/14-/16-bit 串行输入、电压输出型数模转换器。它们采用4.5 V ～16.5 V单电源供电,或者采用±4.5 V ～ ±16.5 V双电源供电。通过软件编程选择来确定输出电压满量程范围,包括+5 V, +10 V, +10.8 V, ±5 V, ±10 V, ±10.8 V。该系列产品还内部集成输出放大器、基准缓冲器以及ADI公司专有的上电/断电控制电路。
该系列产品提供保证的单调性,最大积分非线性误差（INL）为±16 LSB,低噪声,最大建立时间为10 µs。
AD5724/AD5734/AD5754采用串行接口,其工作时钟速率高达30 MHz,而且与DSP以及微控制器接口标准兼容。双重缓冲允许同时更新所有数模转换器。输入编码格式由用户选择,对于双极性输出而言,采用补码二进制或偏移二进制（取决于BIN/2sComp)2sComp引脚的状态）,对于单极性输出而言,采用标准二进制。异步清零功能可以将所有数模转换寄存器清除到用户选择的零刻度或中间刻度。AD5724/AD5734/AD5754采用24引脚TSSOP封装,在-40°C ～ +85°C的工作温度范围内达到技术指标。
