AD5693R/AD5692R/AD5691R均属于nanoDAC+®系列,分别是低功耗、单通道、16/14/12位缓冲电压输出DAC。这些器件均内部集成默认2.5 V基准电压源,提供2 ppm/°C漂移。 输出范围可编程设置为0 V至VREF 或 0 V 至 2 × VREF。 采用2.7 V至5.5 V单电源供电,通过设计保证单调性。 这些器件采用2.00 mm × 2.00 mm、8引脚LFCSP或10引脚MSOP封装。

内部上电复位电路确保DAC寄存器上电时写入零电平,而内部输出缓冲器配置为正常模式。 AD5693R/AD5692R/AD5691R具有关断模式,可在5 V时降低器件功耗至2 μA(最大值),并且提供软件可选的输出负载。

AD5693R/AD5692R/AD5691R采用 I2C接口。 某些器件选项还提供异步 RESET 引脚和 VLOGIC引脚,可兼容1.8 V。

EVAL-AD5693RARDZ

Evaluation Board for AD5693R (I2C, MSOP)

Evaluation Board for AD5693R (I2C, MSOP)

特性和优点

  • Full-featured evaluation boards for the AD5693R (I2C, MSOP)
  • On-board reference
  • Various link options
  • PC control in conjunction with the Analog Devices, Inc., EVALSDP-CK1Z (SDP-K1) controller board

产品详情

This user guide details the operation of the EVAL-AD5683RARDZ (serial peripheral interface (SPI)) evaluation board and the EVALAD5693RARDZ (I2C) evaluation board for the AD5683R (SPI) and the AD5693R (I2C), respectively, which are both single-channel, serial voltage output digital-to-analog converters (DACs).

The EVAL-AD5683RARDZ and the EVAL-AD5693RARDZ are designed to facilitate quick prototyping of the AD5683R and AD5693R circuits, thereby reducing design time. Both devices operate from a single 2.7 V to 5.5 V supply. Additionally, these devices also incorporate an internal 2.5 V on-board reference. A different reference voltage 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 AD5683R employs SPI, while the AD5693R employs I2C.

The EVAL-AD5683RARDZ and the EVAL-AD5693RARDZ interface with the USB port of a PC via the 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-AD5683RARDZ product page and the EVALAD5693RARDZ product page. This software can be used with either evaluation board to allow the user to program the AD5683R and AD5693R, respectively. A PMOD connection is also available to allow the connection of a microcontroller 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-AD5683RARDZ and the EVAL-AD5693RARDZ both require the EVAL-SDP-CK1Z (SDP-K1) controller board, which is available for purchase from Analog Devices.

For full details on the AD5683R and the AD5693R, see the AD5683R and AD5693R data sheets, which must be consulted in conjunction with this user guide when using either of the EVALAD5683RARDZ or the EVAL-AD5693RARDZ evaluation boards.
