XOcont Output Operation
XOcont is the output pin used to output temperature compensation data (XOcont data) corresponding to the
output from the built-in temperature sensor. Data corresponding to each 1 C temperature increment is stored in
the E
2
PROM.
1. Output at power-on
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 s or less.
2. Output caused by trigger input
The rising edge of the Trig.1 input triggers the built-in temperature sensor. The sum of the temperature
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.
The delay time txoc, from Trig.1 input to start of voltage output, is 500 s or less.
3. XOcont data
The XOcont data is stored at addresses 10H 6FH of the E
2
PROM and is used as compensation data
corresponding to every 1 C increment in the ambient temperature range 22 C 73 C.
The voltage output on XOcont corresponds to the 8-bit data stored in the E
2
PROM (0 V for the value
stored at address 00H; V
Ref
for the value stored at address FFH).
When the ambient temperature is outside the range of the E
2
PROM table (i.e. below 22 C or above
73 C), the compensation value for the table’s minimum or maximum temperature ( 22 C or 73 C) is
output.
