| NTE7120 Integrated Circuit 3 Channel Video Amp for High Resolution Color TV Description: The NTE7120 is a semiconductor integrated circuit in a 30-Lead DIP type package that has a built-in 3-channel amplifier with 50MHz band. Every channel is provided with a broad-band amplifier, main/ sub contrast control, main/sub luminance (brightness) control, peaking, blanking, and peak limiter functions. Accordingly, this device is designed for use in high-resolution color display monitors. Features: D The employment of a new bi-polar wafer process makes it possible to reduce power dissipation, and 3 channels can be incorporated in this amplifier (VCC = 12V, ICC = 77mA) D Input: 1VP-P (Typical) Output: VP-P (Maximum) Frequency Band: 50MHz D Main and sub contrast and luminance controls are provided; the main control can change contrast and luminance at the same time for 3 channels, and the sub control can change them independently for each channel. D The DC feedback circuit built in the IC can produce a stable DC level at the IC output pins.
