Serial I/O sampling frequency clock. Output i master mode (Pin 26 = High); input in slave mode
Selects whether 16-bit serial data is input/output at LSB-first or MSB-first. MSB-first when
Analog power supply for Channel-2 AD converter.
Connected to the IC internal circuit board (same electric potential as power supply). Connect
to GND on the printed circuit board via a capacitor.
Digital GND.
IC measurement. Low is output normally.
Test pin. Normally fixed to Low. Equipped with a pull-down resistor.
System clear input. Normally High; cleared when Low. Equipped with a pull-up resistor.
Digital power supply.
Master/slave mode switching input. Master mode when High; slave mode when Low.
Equipped with a pull-up resistor.
(Pin 26 = Low). Transfers Channel-1 data when high, and Channel-2 data when Low.
Serial bit transfer clock (64 f
in master mode (Pin 26 = High); input in slave mode (Pin 26 = Low). Serial input data is re-
trieved at the rising edge; serial output data is transferred at the falling edge.
Two channels per sampling serial data input. Data format is represented by 2’s complements,
and consists of 32-bit slots.
Two channels per sampling serial data input. Data format is represented by 2’s complements,
and consists of 32-bit slots.
Digital GND.
Selects whether 16-bit serial data is place din the first 16-bit or the second 16-bit slots of the
serial I/O 32-bit slots. Forward packing when High; rearward packing when Low.
High; LSB-first when Low.
Crystal selection. Selects the clock frequency to be input from XTLI (Pin 7) using three bits,
XSL 0 to 2.
