Dual Video Amplifier
DESCRIPTION
AA8632 is a dual video amplifier with 6db gain, 75Ω output buffer and SAG correction,
and it supports 3V and 5V operation voltage. The 75Ω buffer is capable of driving two
circuits. The SAG could reduce the output coupling capacitor. The power saving circuit
provides the power saving function. The IC is available in 8-pin TSSOP (AA8632AP),
8-pin SOP (AA8632SP) and 8-pin DIP (AA8632PP) package.
