MICROPOWE R SINGLE -SUPPLY
QUAD VOLT AGE -OUT PUT 8-BIT DAC
T he circuit of Figure 3 uses the DAC8408 CMOS quad 8-bit
DAC, and the OP490 to form a single-supply quad voltage-out-
put DAC with a supply drain of only 140
μ
A. T he DAC8408 is
used in voltage switching mode and each DAC has an output re-
sistance (
10 k
) independent of the digital input code. T he
output amplifiers act as buffers to avoid loading the DACs. T he
100 k
resistors ensure that the OP490 outputs will swing be-
low 0.8 V when required.
