APPLICATION INFORMATION
common buffer (V
COM
)
The common buffer output of the BUF11702 has a greater output drive capability than buffers 1
–
10, to meet the
heavier current demands of driving the common node of the LCD panel. It was also designed to drive heavier
capacitive loads and still remain stable, see Figure 50.

Figure 50. Phase Shift Between Output and Input vs Load Capacitance for Common Buffer
Because the common node of the panel acts like a large capacitor, the common output of the BUF11702 will
have to supply very large pulses of current. In some applications the output drive capability of the BUF11702
might not be sufficient. Therefore discrete amplifiers with high output current drive capability and enough phase
margin to drive large capacitive loads could be used.
Possible alternatives include the OPA551, OPA350, BUF634, TLC081 or TLV4110/1. Because of their wide
bandwidth and the low frequency pole created by the LCD panel common node capacitance, extra
compensation may be required.
