The NTE7116 is a phase lock loop (PLL) stereo decoder in a 20Lead DIP type package designed primarily for low cost stereo decoding in a lowtomediumline TV. The MUX input (Pin1) is a low impedance current input, the gain of the input amplifier is therefore determined by the external resistor R1. All characteristics are measured with R1 = 47k. The deemphasis of (L, R) and (L R) can be chosen by means of external capacitors and resistors. The supply voltage range of the device is from 7V to 16V.
