Selects between the Serial Outputs. When M1 is LOW, both Serial Output A and Serial Output B are selected for data transfer. When M1
is HIGH, Serial output A is configured for both Channel A data and Channel B data; Serial Output B goes into tri-state (i.e., high impedance).

M0
Selects between two-channel and four-channel operation. When M0 is LOW, two-channel operation is selected and operates in
conjunction with A0. When A0 is HIGH, Channel A1 and Channel B1 are being converted. When A0 is LOW, Channel A0 and Channel
B0 are being converted. When M0 is HIGH, four-channel operation is selected. In this mode, all four channels are converted in sequence
starting with Channels A0 and B0, followed by Channels A1 and B1.

A0
A0 operates in conjunction with M0. With M0 LOW and A0 HIGH, Channel A1 and Channel B1 are converted. With M0 LOW and A0 LOW,
Channel A0 and Channel B0 are converted.
17
19
CONVST
Convert Start. When CONVST switches from LOW to HIGH, the device switches from the sample to hold mode, independent of the status
of the external clock.

RD
Synchronization Pulse for the Serial Output.
19
21
CS
Chip Select. When LOW, the Serial Output A and Serial Output B outputs are active; when HIGH, the serial outputs are tri-stated.
20
22
CLOCK
An external CMOS-compatible clock can be applied to the CLOCK input to synchronize the conversion process to an external source.
The CLOCK pin controls the sampling rate by the equation: f
SAMPLE
(max)
= CLOCK/20.
BUSY goes HIGH during a conversion and returns LOW after the third LSB has been transmitted on either the Serial A or Serial B output
pin.

DATA B
The Serial Output data word is comprised of channel information and 16 bits of data. In operation, data is valid on the falling edge of
DCLOCK for 20 edges after the rising edge of RD.

SERIAL
DATA A
The Serial Output data word is comprised of channel information and 16 bits of data. In operation, data is valid on the falling edge of
DCLOCK for 20 edges after the rising edge of RD. When M1 is HIGH, both Channel A data and Channel B data are available.
