Applications Information
Logic Levels
The MAX4800/MAX4801/MAX4802 digital interface
inputs CLK, DIN,
LE
, and CLR are tolerant of up to
+13.2V, independent of the V
DD
supply voltage, allow-
ing compatibility with higher voltage controllers.
Daisy Chaining Multiple Devices
Digital output DOUT is provided to allow the connection
of multiple MAX4800/MAX4801/MAX4802 devices by
daisy chaining (Figure 3). Connect each DOUT to the
DIN of the subsequent device in the chain. Connect CLK,
LE
, and CLR inputs of all devices, and drive
LE
logic-low
to update all devices simultaneously. Drive CLR high to
open all the switches simultaneously. Additional shift reg-
isters may be included anywhere in series with the
MAX4800/MAX4801/MAX4802 data chain.
Supply Sequencing and Bypassing
The MAX4800/MAX4801/MAX4802 do not require spe-
cial sequencing of the V
DD
, V
PP
, and V
NN
supply volt-
ages; however, analog switch inputs must be
unconnected, or satisfy V
NN

, V

)

V
PP
during power-up and power-down. Bypass V
DD
, V
NN
,
and V
PP
to GND with a 0.1μF ceramic capacitor as
close to the device as possible.
Exposed Paddle
The MAX4800 and MAX4802 provide an exposed pad-
dle for improved thermal performance in the TQFN
package. Connect the exposed paddle to V
NN
.
