AD587JRZ-REEL 作为 CMOS 双 DAC 的 10V 基准的典型应用电路。 AD587 还可用作多个 DAC 的精密基准。它显示了 AD587、AD7628 双 DAC 和 AD712 双运算放大器连接起来进行单电源操作,以产生 0V 至 -10V 输出。由于两个 DAC 位于同一芯片上并共享公共参考和输出运算放大器,因此 DAC 输出将表现出相似的增益温度系数 (TC)

Typical Application Circuit for AD587JRZ-REEL as a 10V Reference for a CMOS Dual DAC. The AD587 can also be used as a precision reference for multiple DACs. It shows the AD587, the AD7628 dual DAC and the AD712 dual op amp hooked up for single-supply operation to produce 0V to -10V outputs. Because both DACs are on the same die and share a common reference and output op amps, the DAC outputs will exhibit similar gain temperature coefficients (TCs)
