Description
1
DATEN
Data Enable Low Input. This port controls the 8-bit parallel data latch and shift register. A Logic
0-to-1 transition transfers the latched data to the attenuator core (updates the gain) and simulta-
neously inhibits serial data transfer into the register. A 1-to-0 transition inhibits the data latch
(holds the previous gain state) and simultaneously enables the register for serial data load.
2
SDATA
Serial Data Input. This digital input allows for an 8-bit serial (gain) word to be loaded into the
internal register with the MSB (Most Significant Bit) first and ignored.
3
CLK
Clock Input. The clock port controls the serial attenuator data transfer rate to the 8-bit master-
slave register. A Logic 0-to-1 transition latches the data bit and a 1-to-0 transfers the data bit to
the slave. This requires the input serial data word to be valid at or before this clock transition.
4, 28
GND
Common External Ground Reference
5, 9, 10, 19,
VCC
Common Positive External Supply Voltage. A 0.1
F capacitor must decouple each pin.
20, 23, 27
6
TXEN
Transmit Enable pin. Logic 1 powers up the part.
7
SLEEP
Low Power Sleep Mode. In the Sleep mode, the AD8326’s supply current is reduced to 4 mA. A
Logic 0 powers down the part (High ZOUT State) and a Logic 1 powers up the part.
8, 12, 17
NC
No Connection to these pins.
11, 13, 16, 18,
VEE
Common Negative External Supply Voltage. A 0.1
F capacitor must decouple each pin.
22, 24
14
OUT–
Negative Output Signal
15
OUT+
Positive Output Signal
21
BYP
Internal Bypass. This pin must be externally ac-coupled (0.1
F capacitor).
25
VIN+
Noninverting Input. DC-biased to approximately VCC/2. Should be ac-coupled with a
0.1
F capacitor.
26
VIN–
Inverting Input. DC-biased to approximately VCC/2. Should be ac-coupled with a 0.1
F capacitor.
