S Low Average Operating Current (100µA at 14V) S 1.2.fF LSB Capacitance-to-Digital Resolution (5pF
MAX1441
The MAX1441 proximity and touch sensor IC is designed for capacitive proximity sensing in automotive passive remote keyless entry (PRKE) and other applications. This device provides signal processing to support two independent touch/proximity sensor channels. The device features two open-drain output pins with highvoltage capability up to 28V, as well as five digital I/Os to indicate sensing events. During manufacturing, JTAG programming uses four digital I/Os.
