Current Limiter
By adding a single resistor as shown in Figure 5, the
MX581 is turned into a precision current limiter for
applications where the driving voltage is 12.5V to 40V.
The programmed current ranges from 0.75mA to 5mA.
Negative 10V Reference
Where a -10V reference is required, the MX581 can be
connected as a two-terminal device and biased like a
zener diode. The circuit is shown in Figure 6. +VS and
VOUT are connected to the system’s analog ground
and the MX581’s GND pin is connected, through a
resistor, to the negative supply. With 1mA flowing in the
reference, the output voltage is typically 2mV greater
than what is obtained with the conventional, positive
hook-up.
When using the 2-terminal connection, the load and the
bias resistor must be selected so that the current flow-
ing in the reference is maintained between 1mA and
5mA. The operating temperature range for this connec-
tion is limited to -55°C to +85°C.
Reference for CMOS DACs and ADCs
The MX581 is well suited for use with a wide variety of
digital-to-analog converters, especially CMOS DACs.
Figure 7 shows a circuit in which an MX7533 10-bit
DAC outputs 0 to -10V when using a +10V reference.
For a positive DAC output, the MX581 is configured as
a 2-terminal -10V reference (Figure 6) and connected
to the DAC’s VREF input.
In Figure 8, an MX7574 CMOS ADC uses an MX581 for
its -10V reference input. The input range for the ADC is
0 to +10V.
