Bipolar Output
The MAX5154/MAX5155 can be configured for a bipo-
lar output, as shown in Figure 11. The output voltage is
given by the equation (OS_ = AGND):
V
OUT
= V
REF
[((2 x 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 Referenc e
In applications where the reference has an AC signal
component, the MAX5154/MAX5155 have multiplying
capabilities within the reference input voltage range
specifications. Figure 12 shows a technique for apply-
ing 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. The typical -3dB frequency is 300kHz
for both devices, as shown in the Typical Operating
Characteristics.
Digital Calibration and
T hreshold S elec tion
Figure 13 shows the MAX5154/MAX5155 in a digital
calibration application. With a bright light value applied
to the photodiode (on), the DAC is digitally ramped until
