GENERAL DESCRIPTION
The SPT9405 is a single video line driver chip that takes a standard video signal as an analog input and provides a buffered analog output for driving a 150 Ω load (75 Ω backterminated cable). The standard video input signal (1 VP-P) is internally clamped and amplified 6 dB using internal circuitry and feedback resistors to produce a 2 VP-P into an ACcoupled 150Ωload.The internal 1.5 kΩ resistor provides gain compensation for low frequency signals. (See the typical interface circuit diagram.)
