Analog Power Ground Pin
Input Analog Power Pin. Nominally 5 V.
Multiplexer Select. When LOW, the analog inputs INA1 and INB1 are sampled simul-
taneously, then converted. When HIGH, the analog inputs INA2 and INB2 are sampled
simultaneously, then converted.
Parallel Mode Selection (8 Bit, 16 Bit). When LOW, the LSB is output on D[7:0]
and the MSB is output on D[15:8]. When HIGH, the LSB is output on D[15:8] and
the MSB is output on D[7:0].
Data Channel Selection. In parallel mode, when LOW, the data from channel B is
read. When HIGH, the data from channel A is read. In serial mode, when HIGH,
channel A is output first followed by channel B. When LOW, channel B is output
first followed by channel B.
Digital Power Ground
Mode Selection. When HIGH, this input selects a reduced power mode. In this mode,
the power dissipation is approximately proportional to the sampling rate.
Serial/Parallel Selection Input. When LOW, the parallel port is selected; when HIGH, the
serial interface mode is selected and some bits of the DATA bus are used as a serial port.
Bit 0 and Bit 1 of the Parallel Port Data Output Bus. When SER/
PAR
is HIGH, these
outputs are in high impedance.
When SER/
PAR
is LOW, these outputs are used as Bit 2 and Bit 3 of the Parallel Port
Data Output Bus.
When SER/
PAR
is HIGH, EXT/
INT
is LOW, and RDC/SDIN is LOW, which is the
serial master read after convert mode, these inputs, part of the serial port, are used to
slow down if desired the internal serial clock that clocks the data output. In the other
serial modes, these inputs are not used.
When SER/
PAR
is LOW, this output is used as Bit 4 of the Parallel Port Data
Output Bus.
When SER/
PAR
is HIGH, this input, part of the serial port, is used as a digital select
input for choosing the internal or an external data clock, called respectively, Master
and Slave Mode. With EXT/INT tied LOW, the internal clock is selected on SCLK
output. With EXT/INT set to a logic HIGH, output data is synchronized to an external
clock signal connected to the SCLK input.
