Single Supply Video Line Driver (AC Coupled)

Aug 13th 2004
When AC-coupling video, the waveform dynamics change with respect to the bias point of the amplifi er according to the scene brightness of the video stream. In the worst case, 1VP-P video (composite or Luminance + Sync in Y/C or YPBPR format) can exhibit a varying DC content of 0.56V, with the dynamic requirement being ...

Low Noise AC Amplifier with Programmable Gain and Bandwidth

Jan 20th 2000
Two LTC6910 programmable gain amplifiers can be combined to provide independent gain and bandwidth control using two 3 bit digital words. The Gain Control PGA simply varies the circuit gain from 1 to 100. The Bandwidth Control PGA puts signal gain inside the feedback loop of the amplifier. As this gain is increased the effective ...

Balanced Frequency Converter (Suitable for Frequencies up to 50kHz)

Nov 16th 1992
This circuit takes advantage of aliasing that occurs in any time sampled system. The output signal frequency is the difference in frequency between the input signal and the switch sampling rate. A 24KHz input signal sampled at 25KHz will be converted to a 1KHz output signal. In addition by using the LTC1992 fully differential ...
