单路电压和电流输出的16位数模转器AD5758主要特性_功能框图以及评估板
adi公司的ad5758是单路电压和电流输出的16位数模转器(dac),工作电压从-33v (avss)到+33v(avdd1),16位性能,片上有诊断功能包括12位adc,用户可编失调和增益,电流输出范围0 ma - 20 ma, 4 ma - 20 ma, 0 ma - 24 ma, ±20 ma, ±24 ma, −1 ma - +22 ma ,电压输出范围0 v - 5 v, 0 v - 10 v, ±5 v和±10 v,工作温度范围−40°c 到 +11°5c,主要用在过程控制,激励器控制,通路隔离的模拟输出,可编逻辑控制器(plc)和分布式控制系统(dcs)以及hart网络连接.本文介绍ad5758产品亮点和主要特性,功能框图以及评估板eval-ad5758sdz主要特性,电路图,材料清单和pcb设计图.
the ad5758 is a single-channel, voltage and current output digital- to-analog converter (dac) that operates with a power supply range from −33 v (minimum) on avss to +33 v (maximum) on avdd1 with a maximum operating voltage between the two rails of 60 v. on-chip dynamic power control (dpc) minimizes package power dissipation, which is achieved by regulating the supply voltage (vdpc+) to the viout output driver circuitry from 5 v to 27 v using a buck dc-to-dc converter, optimized for minimum on-chip power dissipation. the chart pin enables a hart® signal to be coupled onto the current output. the device uses a versatile 4-wire serial peripheral interface (spi) that operates at clock rates of up to 50 mhz and is compatible with standard spi, qspi™, microwire™, dsp, and microcontroller interface standards. the interface also features an optional spi cyclic redundancy check (crc) and a watchdog timer (wdt). the ad5758 offers improved diagnostic features from its predecessors, such as output current monitoring and an integrated 12-bit diagnostic analog-to-digital converter (adc). additional robustness is provided by the inclusion of a fault protection switch on the viout, +vsense, and −vsense pins.
