Maxim Integrated
MAX5395
Single, 256-Tap Volatile, I2C, Low-Voltage Linear
Taper Digital Potentiometer
SD_L_WREG Command
Opens the L terminal and maintains the wiper at the wiper
register location. Writes cannot be made to the wiper
register while shutdown mode is engaged. Clearing
shutdown mode will close the L terminal and allow wiper
register to be written. A RST will also deassert shutdown
mode and return the wiper to midscale (0x80). This
command does not affect the charge-pump status.
SD_L_ZERO Command
Moves wiper to zero-scale position (0x00) and opens the
L terminal. The wiper register remains unaltered. Writes
cannot be made to the wiper register while shutdown
mode is engaged. Clearing shutdown mode will return
the wiper to the position contained in the wiper register
and close the L terminal. A RST will also deassert
shutdown mode and return the wiper to midscale (0x80).
This command does not affect the charge-pump status.
SD_L_MID Command
Moves wiper to midscale position (0x80) and opens the
L terminal. The wiper register remains unaltered. Writes
cannot be made to the wiper register while shutdown
mode is engaged. Clearing shutdown mode will return
the wiper to the position contained in the wiper register
and close the L terminal. A RST will also deassert
shutdown mode and return the wiper to midscale (0x80).
This command does not affect the charge-pump status.
SD_L_FULL Command
Moves wiper to full-scale position (0xFF) and opens the
L terminal. The wiper register remains unaltered. Writes
cannot be made to the wiper register while shutdown
mode is engaged. Clearing shutdown mode will return
the wiper to the position contained in the wiper register
and close the L terminal. A RST will also deassert
shutdown mode and return the wiper to midscale (0x80).
This command does not affect the charge-pump status.
SD_W Command
Opens the W terminal keeping the internal tap position
the same as the wiper register. Writes cannot be made
to the wiper registers while shutdown mode is engaged.
Clearing shutdown mode will return the wiper to the
position contained in the wiper register and close W
terminal. A RST will also deassert shutdown mode and
return the wiper to midscale (0x80). This command does
not affect the charge-pump status.
QP_OFF Command
Disables the onboard charge pump and places device in
low power mode. Low supply voltage is limited to 2.6V.
QP_ON Command
Enables the onboard charge pump to allow low-supply
voltage operation. This is the power-on default condition.
Low supply voltage is 1.7V.
RST Command
Returns the device to power-on default conditions.
Resets the wiper register to midscale (0x80), enables
charge pump, and deasserts any shutdown modes.
