产品详情

The user guide details the operation of the EVAL-AD5675RARDZ (I2C) evaluation board and the EVAL-AD5676R2ARDZ (serial peripheral interface (SPI)) evaluation board for the AD5675R (TSSOP, I2C) and AD5676R (TSSOP, SPI), respectively, which are both octal channel, voltage output digital-to-analog converters (DACs).

The EVAL-AD5675RARDZ and the EVAL-AD5676R2ARDZ evaluation boards are designed to facilitate quick prototyping of the AD5675R or AD5676R circuits, thereby reducing design time. Both devices operate from a single 2.7 V to 5.5 V supply. Additionally, these devices both have an internal 2.5 V reference. A different reference voltage (VREF) can be applied via the EXT_REF SMB connector, if required. While sharing common features, the two DACs differ in their digital interface protocols. The AD5676R employs SPI, while the AD5675R employs I2C.

The EVAL-AD5675RARDZ and the EVAL-AD5676R2ARDZ evaluation boards interface to the USB port of a PC via a System Demonstration Platform (SDP) controller board (EVAL-SDP-CK1Z (SDP-K1)). The Analysis | Control | Evaluation (ACE) software is available for download from both the EVAL-AD5675RARDZ product page and the EVAL-AD5676R2ARDZ product page. This software can be used with the evaluation board to allow the user to program the AD5675R and AD5676R, respectively. A PMOD connection is also available to allow the connection of microcontrollers to either evaluation board. Note that when a microcontroller is used through the PMOD connection, the EVAL-SDP-CK1Z (SDP-K1) must be disconnected, and the user cannot use the ACE software.

The EVAL-AD5675RARDZ and the EVAL-AD5676R2ARDZ both require the EVAL-SDP-CK1Z (SDP-K1) controller board, which are available for purchase from Analog Devices. For full details on the AD5675R and the AD5676R, see the AD5675R and AD5676R data sheets, which must be consulted in conjunction with this user guide when using the EVALAD5675RARDZ or the EVAL-AD5676R2ARDZ evaluation boards.

产品详情

The EVAL-AD5676RARDZ allows users to quickly prototype AD5676R circuits and reduce design time. The AD5676R operates from a single 2.7 V to 5.5 V supply. The AD5676R incorporates an internal 2.5 V reference to give a full-scale output voltage of 2.5 V or 5 V. An ADR4525 is also provided on-board as a 2.5V reference source. A different external reference voltage can be applied via the EXT_REF SMB connector or test pin if needed.

The EVAL-AD5676RARDZ interfaces to the USB port of a PC via a system demonstration platform board (SDP-K1 ). The Analysis | Control | Evaluation (ACE) software is available for download from the EVAL-AD5676RARDZ product page to use with the evaluation board to allow the user to program the AD5676R. A peripheral module interface (PMOD) connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP-K1 board. When a microcontroller is used through the PMOD connection, the SDP-K1 board must be disconnected, and the user is unable to operate the ACE software.

The EVAL-AD5676RARDZ is compatible with the EVAL-SDP-CK1Z (SDP-K1), which should be purchased separately. A typical connection between the EVAL-AD5676RARDZ and the SDP-B controller board is shown in the user guide. For full details, see the AD5676R data sheet, which must be used in conjunction with the user guide when using the EVAL-AD5676RARDZ.

产品详情

该用户指南对AD5676/AD5676R八通道、电压输出数模转换器(DAC)的评估板操作进行详细说明。

EVAL-AD5676SDZ/EVAL-AD5676RSDZ评估板可帮助客户快速进行新型AD5676/AD5676R电路原型制作，并缩短设计时间。 AD5676/AD5676R采用2.7 V至5.5 V单电源供电。 AD5676R内置一个2.5 V基准电压源，最大输出电压为2.5 V至5 V。AD5676不包含内部基准电压源。因此，ADR431可作为2.5 V片内基准电压源。 如果需要，通过EXT_REF SMB连接器可施加不同的基准电压。


ADI的AD5676/AD5676R相应数据手册上提供有关该器件的完整数据，使用评估板时，应同时参阅数据手册和本用户指南。

评估板通过SDP板与PC的USB端口连接。 软件与评估板一同提供，便于用户设置AD5676/AD5676R。

此评估板与EVAL-SDP-CB1Z Blackfin® SDP控制器板(SDP-B)兼容，后者可在ADI网站上订购： www.analog.com。
