input register and transferring the 12 bits of data into the de-
coded address determined by the address bits A and B in the se-
rial input register.
Unipolar Output Operation
T his is the basic mode of operation for the AD8522. T he
AD8522 has been designed to drive loads as low as 820
in
parallel with 500 pF. T he code table for this operation is shown
in T able III.

T IMING AND CONT ROL
T he AD8522 has a 16-bit serial input register that accepts
clocked in data when the CS pin is active low. T he DAC regis-
ters are updated by the Load Enable (
LDA
and
LDB
) pins.
T he AD8522 offers two modes of data loading. T he first mode,
hardware-load, directs the data currently clocked into the serial
shift register into either the DAC A or the DAC B register or
both depending on the external active low strobing of the
LDA
or
LDB
pin. Serial data register bit Sf/
Hd
must be low for this
mode to be in effect.
T he second mode of operation is software-load which is de-
signed to minimize the number of control lines connected to
the AD8522. In this mode of operation the
LDA
and
LDB
pins
act as one control input taking the present contents of the serial
