The MAX5352’s total harmonic distortion plus noise
(THD+N) is typically less than -77dB (full-scale code),
and the MAX5353’s THD+N is typically less than
-72dB (full-scale code), given a 1Vp-p signal swing and
input frequencies up to 25kHz. The typical -3dB fre-
quency is 650kHz for both devices, as shown in the
Typical Operating Characteristics graphs.
Digitally Programmable Current S ourc e
The circuit of Figure 12 places an NPN transistor
(2N3904 or similar) within the op-amp feedback loop to
implement a digitally programmable, unidirectional cur-
rent source. The output current is calculated with the
following equation:
I
OUT
= (V
REF
/R) x (NB/4096)
where NB is the numeric value of the DAC’s binary
input code and R is the sense resistor shown in
Figure 12.
