NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. PIN DESCRIPTIONSPotentiometer PinsHost Interface PinsVH/RH (VH0/RH0 - VH1/RH1), VL/RL (VL0/RL0 - VL1/RL1) The VH/RH and VL/RL inputs are equivalent to the Serial Clock (SCL) terminal connections on either end of a mechanical The SCL input is used to clock data into and out of the potentiometer. X9418. VW/RW (VW0/RW0 - VW1/RW1)Serial Data (SDA) The wiper outputs are equivalent to the wiper output of a SDA is a bidirectional pin used to transfer data into and mechanical potentiometer. out of the device. It is an open drain output and may be wire-ORed with any number of open drain or open Hardware Write Protect Input (WP) collector outputs. An open drain output requires the use The WP pin when low prevents nonvolatile writes to the of a pull-up resistor. For selecting typical values, refer to Data Registers. the guidelines for calculating typical values on the bus pull-up resistors graph. Analog Supplies V+, V- The Analog Supplies V+, V- are the supply voltages for Device Address (A0 -A3) the XDCP analog section. The Address inputs are used to set the least significant 4 bits of the 8-bit slave address. A match in the slave address serial data stream must be made with the Address input in order to initiate communication with the X9418. A maximum of 16 devices may occupy the 2- wire serial bus.
