Pin Functions

PIN I/O DESCRIPTION
NAME BGA MICROSTAR JUNIOR SON,
MSOP-PowerPAD
BYPASS C1 2 I Mid-supply voltage. Adding a bypass capacitor improves PSRR.
GND B2 7 I High-current ground
IN– C3 4 I Negative differential input
IN+ C2 3 I Positive differential input
SHUTDOWN B1 1 I Shutdown terminal (active low logic)
VDD A3 6 I Supply voltage terminal
VO+ B3 5 O Positive BTL output
VO– A1 8 O Negative BTL output
Thermal Pad N/A — — Connect to ground. Thermal pad must be soldered down in all applications to properly secure device on the PCB.
