This TS636 is particularly intended for applications such as preamplification in telecommunication systems using multiple carriers.

a high input impedance and a low noise current. To minimize the overall noise figure, the source impedance must be less than 3kΩ. This value gives an equal contribution of voltage and current noises. The second stage is a gain/attenuation stage (+12dB to -9dB) featuring a low output impedance. This output stage can drive loads as low as 500Ω. v Input1 + _ _ Ouput1 + +Vcc1 v -Vcc Analog GND (AGND) v + + _ Ouput2 +Vcc2 Input2 _ v v GAIN.
