AD5754RBREZ-REEL7:  完全4通道、12/14/16-Bit、串行输入、单极/双极电压输出数模转换器

The AD5724R/AD5734R/AD5754R are quad, 12-/14-/16-bit serial input, voltage output, digital-to-analog converters (DACs). They operate from single supply voltages of +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, 10 μs typical settling time, and an on-chip +2.5 V reference.

The AD5724R/AD5734R/AD5754R 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 mid-scale output. The parts are available in a 24-lead TSSOP and offer guaranteed specifications over the −40°C to +85°C industrial temperature range.

AD5724R/AD5734R/AD5754R是4通道12-/14-/16-bit 串行输入、电压输出、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。额定标称满刻度输出电压范围是由软件选择的,包括+5 V, +10 V, +10.8 V, ±5 V, ±10 V, ±10.8 V。该产品还包括集成输出放大器、基准缓冲器、以及具有ADI公司专有的上电/断电控制电路。

该产品提供确保的单调性,最大积分非线性误差为±8 LSB,低噪声,最大建立时间为10 μs,芯片基准电压为+2.5 V

AD5724R/AD5734R/AD5754R采用串行接口,其工作时钟速率高达30 MHz,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。输入编码由用户选择,对于双极输出而言,输入编码采用补码二进制或偏移二进制(取决于Pin BIN/2sComp的状态),对于单极输出而言,输入编码采用标准二进制。异步清除功能可以对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。AD5724R/AD5734R/AD5754R采用24引脚TSSOP封装,在工作温度范围-40°C ~ +85°C达到技术指标。
