The
VDA-6830 is a general purpose distribution amplifier with excellent
linearity and gain stability for solving common mode errors. It can handle
anything from nominally 0.7Vp-p non-composite video to 2Vp-p subcarrier.
Low power consumption and high temperature stability make this a very
reliable, inexpensive distribution amplifier.
Variable Gain Control
The VDA-6830 provides a differential input when equalization and clamping
are not required. Although normally used as a unity gain amplifier, a
variable gain control on the module front edge with a range from -3dB to
+3dB allows compensation for non-standard input levels or line losses.
