Functio n

Analog input pin for expanding the range .

Analog output pin for expanding the range . Connect to any pin from AO to A3 . By using Ex . 1, Ex . 2, the range is expanded to the x4 range .

4-ch analog input pin . Channel 1 is selected by channel select input CO to Cl .

The input pin to designate the analog input channel for A/D converter . This signal is latche d at the trailing edge of CS .

This is the chip select input pin . When CS is inverted from "1" to "0", A/D convertin g starts and data output is enabled . After A/D converting is over or when an interrupt is re - quired, set the CS back to "1" .

This is the clock input pin for A/D convertion input to the comparator register sequentially . Convertion speed is determined by the clock speed . In the case of 8-bit, approx . 10 clock s will be needed . However, it is not necessary that the clock period be fixed .

This is the open collector to output the result of A/D convertion . The data is output in th e order of the start bit, most significant bit, 2nd significant bit, . . ., least significant bit, an d the stop bit, synchronized with ADCCLK .

When driving with 3 .5 to 6 .0 V of power, connect Vcc, and Vcc 2 to each other, and appl y the power voltage to them .

When driving 8 to 18 V of power, apply the power voltage to Vcc 2 . At this time, the 5 V stabilized voltage is output to Vcc,, and approx . 10 mA current can be supplied externall y to the IC .

When either 3 .5--6 .0 V or 8— 18V power is used, Vcc, is the reference voltage for A/ D convertion .
