DAC900使用说明

10-Bit, 165MSPS

引脚图见PDF

      常用接口：BIT0-BIT9（10位数据输入）接IO口,注意BIT0对应MSB,BIT9对应LSB。PD（停止控制位，高电平有效）接低电平，CLK接时钟。电流输出型，后面加上I/V电路。

工作电压DAC900 can be operated on a wide, single-supply range of+2.7V to +5.5V.

The DAC900 comes with an integrated 1.24V bandgap refer-ence and edge-triggered input latches, offering a complete converter solution. Both +3V and +5V CMOS logic families can be interfaced to the DAC900。

用HJJ开的板测试：示波器直流档测满幅输出为1.00V,控制字为0时输出-880mv

用MSP430驱动DAC900用查表法生产固定频率正弦波，示波器测试结果如下：
