Figure 6. Micropower Single-Supply Quad Voltage Output 8-Bit DAC
Micropower Single-Supply Quad Voltage-Output 8-Bit DAC
The circuit of Figure 6 uses the DAC8408 CMOS quad 8-bit
DAC, and the OP490 to form a single-supply quad voltage-output
DAC with a supply drain of only 140
m
A. The DAC8408 is used
in voltage switching mode and each DAC has an output resistance
(
a
10 k
W
) independent of the digital input code. The output
amplifiers act as buffers to avoid loading the DACs. The 100 k
W
resistors ensure that the OP490 outputs will swing below 0.8 V
when required.
