Low-Power, Dual, Voltage-Output, 12-Bit DAC
with Serial Interface
The P then programs the DAC to set an output voltage
at the midpoint of the two calibrated values. Applications
include tachometers, motion sensing, automatic readers,
and liquid-clarity analysis.
Digital Control of Gain and Offset
The two DACs can be used to control the offset and gain
for curve-fitting nonlinear functions, such as transducer
linearization or analog compression/expansion applica-
tions. The input signal is used as the reference for the
gain-adjust DAC, whose output is summed with the output
from the offset-adjust DAC. The relative weight of each
DAC output is adjusted by R1, R2, R3, and R4 (Figure 14).
Power-Supply Considerations
On power-up, the input and DAC registers clear (set to
zero code). For rated performance, VREF_ should be at
least 1.4V below VDD. Bypass the power supply with a
4.7F capacitor in parallel with a 0.1F capacitor to
AGND. Minimize lead lengths to reduce lead inductance.
Grounding and Layout Considerations
Digital and AC transient signals on AGND can create
noise at the output. Connect AGND to the highest quality
ground available. Use proper grounding techniques,
such as a multilayer board with a low-inductance ground
plane. Carefully lay out the traces between channels to
reduce AC cross-coupling and crosstalk. Wire-wrapped
boards and sockets are not recommended. If noise
becomes an issue, shielding may be required.
