MAX5104
Low-Power, Dual, Voltage-Output, 12-Bit DAC
with Serial Interface
______________________________________________________________________________________

MAX5104
VOUT = VREF [((2 NB) / 4096) - 1]
where NB represents the numeric value of the DAC’s
binary input code. Table 3 shows digital codes and the
corresponding output voltage for Figure 11’s circuit.
Using an AC Reference
In applications where the reference has an AC signal
component, the MAX5104 has multiplying capabilities
within the reference input voltage range specifications.
Figure 12 shows a technique for applying a sinusoidal
input to REF_, where the AC signal is offset before
being applied to the reference input.
Harmonic Distortion and Noise
The total harmonic distortion plus noise (THD+N) is typ-
ically less than -78dB at full scale with a 1Vp-p input
swing at 5kHz.
Digital Calibration and
Threshold Selection
Figure 13 shows the MAX5104 in a digital calibration
application. With a bright-light value applied to the pho-
todiode (on), the DAC is digitally ramped until it trips
the comparator. The microprocessor (P) stores this
“high” calibration value. Repeat the process with a dim
light (off) to obtain the dark current calibration.
