Figure 13. Micropower Single-Supply Quad Voltage-
Output 8-Bit DAC
A Single-Supply Micropower Quad Programmable-Gain
Amplifier
The combination of the quad OP493 and the DAC8408 quad
8-bit CMOS DAC creates a quad programmable-gain amplifier
with a quiescent supply drain of only 140
A (Figure 14). The
digital code present at the DAC, which is easily set by a micro-
processor, determines the ratio between the fixed DAC feedback
resistor and the resistance that the DAC feedback ladder pre-
sents to the op amp feedback loop. The gain of each amplifier is:
V
Vn
OUT
IN
=
256
where n equals the decimal equivalent of the 8-bit digital code
present at the DAC.
If the digital code present at the DAC consists of all zeros, the
feedback loop will be open causing the op amp to saturate. The
10 M
resistors placed in parallel with the DAC feedback loop
eliminates this problem with a very small reduction in gain
accuracy. The 2.5 V reference biases the amplifiers to the center
of the linear region providing maximum output swing.
