applications where the driving voltage is 5V to 40V. The
programmed current ranges from 0.75mA to 5mA.

Chip Topography
In applications which require a -10V, -7.5V, -5.0V, or
-2.5V reference, the MX584 can be connected as a
two-terminal device and biased like a zener diode. The
circuit is shown in Figure 9. +V S and V OUT are connect-
ed to the analog ground bus, and the MX584’s COM-

V BG
MON 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 DACs and ADCs
The MX584 is well suited for use with a wide variety of
DACs, especially CMOS DACs. Figure 10 shows a cir-
cuit in which an MX7533 10-bit DAC outputs 0 to -5V
when using a +5V reference. For a positive DAC out-
put, the MX584 can be configured as a two-terminal
negative reference as well by using the connection of
Figure 9.

Chip Information
In Figure 11, an MX7574 CMOS ADC uses an MX584,
connected for -2.5V, as its reference input so that the
system can operate from ±5V power. The analog input
range for the circuit is 0V to +2.5V.
