NTE906
Integrated Circuit
Dual, High Frequency, Differential Amplifier
Description:
The NTE906 is an integrated circuit in a 12–Lead TO5 type package consisting of two independent
differential amplifiers with associated constant–current transistors on a common monolithic substrate. The six transistors which comprise the amplifiers are general–purpose devices which exhibit
low 1/f noise and a value of fT in excess of 1GHz. These features make the NTE906 useful from DC
to 500MHz. Bias and load resistors have been omitted to provide maximum application flexibility.
The monolithic construction of the NTE906 provides close electrical and thermal matching of the amplifiers. This feature makes this device particularly useful in dual–channel applications where
matched performance of the two channels is required.

Note 1. The collector of each transistor is isolated from the substrate by an integral diode. The substrate (Pin9) must be connected to the most negative point in the external circuit to maintain
isolation between transistors and to provide for normal transistor action.
