Terminal Connections
/
Ground connection
+5V Power supply for the input amplifier, variable attenuator, and serial
interface. Bypass to GND1 with a 0.1 µF decoupling capacitor as close to
the part as possible.
No connect
Ground connection for the input amplifier and variable attenuator
Positive input to the input amplifier
Negative input to the input amplifier. Bypass with capacitor if driving
amplifier single-ended.
Ground connection to serial interface
Chip select input to serial interface (active low)
Data input to serial interface (active high)
Clock input to serial interface (positive-edge triggered)
No connect
Shutdown mode input (active low)
No connect
Output common-mode bypass. Bypass to GND2 with 0.1 µF capacitor.
PA negative output
PA positive output
No connect
PA output enable input (active high)
+5V Power supply for PA bias and control circuitry. Bypass to GND2 with a
0.1 µF decoupling capacitor as close to the part as possible.
