Description
The MCP41HVX1 family of devices have dual power
rails (analog and digital). The analog power rail allows
high voltage on the resistor network terminal pins. The
analog voltage range is determined by the V+ and V-
voltages. The maximum analog voltage is +36V, while
the operating analog output minimum specifications are
specified from either 10V or 20V. As the analog supply
voltage becomes smaller, the analog switch resistances
increase, which affects certain performance specifica-
tions. The system can be implemented as dual rail
(±18V) relative to the digital logic ground (DGND).
The device also has a Write Latch (WLAT) function,
which will inhibit the volatile wiper register from being
updated (latched) with the received data until the WLAT
pin is low. This allows the application to specify a con-
dition where the volatile wiper register is updated (such
as zero crossing).

Note 1: Floating either terminal (A or B) allows the device to be used as a Rheostat (variable resistor).
2: This is relative to the DGND signal. There is a separate requirement for the V+/V- voltages: VL V- + 2.7V.
3: Relative to V-, the VL and DGND signals must be between (inclusive) V- and V+.
4: Analog operation will continue while the V+ voltage is above the device’s analog Power-on Reset
(POR)/Brown-out Reset (BOR) voltage. Operational characteristics may exceed specified limits while the
V+ voltage is below the specified minimum voltage.
5: For additional information on these devices, refer to DS20005304.
