The MAX535’s total harmonic distortion plus noise (THD
+ N) is typically less than -77dB (full-scale code), and
the MAX5351’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 frequency 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. This circuit can be used to drive 4–20mA
current loops, which are commonly used in industrial-
control applications. The output current is calculated
with the following equation:
I
OUT
= (V
REF
/ R) x (NB / 8192)
where NB is the numeric value of the DAC’s binary
input code and R is the sense resistor shown in
Figure 12.
