PIN FUNCTIONS
VIN1, VIN2, (BANK1 and BANK2); (F1-F4, E1-E4, C1-C2,
D1-D2) and (J1-J2, K1-K2, L1-L4, M1-M4): Power Input
Pins. Apply input voltage between these pins and GND
pins. Recommend placing input decoupling capacitance
directly between VIN pins and GND pins.
VOUT1, VOUT2 (BANK3 and BANK6); (D9-D12, E9-E12,
F9-F12) and (K9-K12, L9-L12, M9-M12): Power Output
Pins. Apply output load between these pins and GND
pins. Recommend placing output decoupling capacitance
directly between these pins and GND pins. See Table 1.

GND1 and GND2 (BANK2 and BANK5); (A1-A5, A12, B1-
B5, B7-B12, C3-C12, D3-D7) and (G1-G5, G12, H1-H5,
H7-H12, J3-J12, K3-K7): Power Ground Pins for Both
Input and Output Returns.
SVIN1 and SVIN2 (E5 and L5): Signal Input Voltage for Each
Channel. This pin is internally connected to VIN through
a lowpass filter.
SGND1 and SGND2 (F5 and M5): Signal Ground Pin for
Each Channel. Return ground path for all analog and low
power circuitry. Tie a single connection to the output
capacitor GND in the application. See layout guidelines
in Figure 17.
