Xocont output
XOcont is the output pin used to output temperature compensation data (XOcont data) corresponding to the

Trig1. input
sensor output and 25°C temperature sensor compensation data (stored at address 0FH) is used as the
XOcont data address. The XOcont data is converted to an analog voltage level and output on XOcont.

At power-on, 1/2 x ref. voltage (80H) is output on XOcont.
Delay time tpux, from power-on to start of output of 1/2 x ref. voltage, is 100 ms or less.
The rising edge of the Trig.1 input triggers the built-in temperature sensor. The sum of the temperature
The delay time txoc, from Trig.1 input to start of voltage output, is 500 ms or less.
The XOcont data is stored at addresses 10H~6FH of the E
