To compensate for the SSM2018’s gain constant temperature
coefficient of –3300 ppm/
°C, a 1 k, temperature-sensitive
resistor (R7) manufactured by the Precision Resistor Com-
pany with a temperature coefficient of +3500 ppm/
°C is used.
A CCON of 1
F provides a control transition time of 1 ms which
yields a click-free change in the audio channel attenuation. Sym-
metry and offset trimming details of the VCA can be found in
the SSM2018 data sheet.

“Compensator” can be

A High-Compliance, Digitally Controlled Precision Current
Source
The circuit in Figure 38 shows the DAC8562 controlling a
high-compliance, precision current source using an AMP05 in-
strumentation amplifier. The AMP05’s reference pin becomes
the input, and the “old” inputs now monitor the voltage across a
precision current sense resistor, RCS. Voltage gain is set to unity,
so the transfer function is given by the following equation:
I
OUT =
V
IN
R
CS
If RCS equals 100
, the output current is limited to +10 mA
with a 1 V input. Therefore, each DAC LSB corresponds to
2.4
A. If a bipolar output current is required, then the circuit
in Figure 33 can be modified to drive the AMP05’s reference
pin with a
±1 V input signal.
Potentiometer P1 trims the output current to zero with the in-
put at 0 V. Fine gain adjustment can be accomplished by adjust-
ing R1 or R2.
A Digitally Programmable Window Detector
A digitally programmable, upper/lower limit detector using two
DAC8562s is shown in Figure 39. The required upper and
lower limits for the test are loaded into each DAC individually
by controlling HDAC/LDAC. If a signal at the test input is not
within the programmed limits, the output will indicate a logic
zero which will turn the red LED on.
