GENERAL DESCRIPTION

The ALD1106/ALD1116 are monolithic quad/dual N-channel enhance-

ment mode matched MOSFET transistor arrays intended for a broad range

of precision analog applications. The ALD1106/ALD1116 offer high input

impedance and negative current temperature coefficient. The transistor

pairs are matched for minimum offset voltage and differential thermal

response, and they are designed for switching and amplifying applications

in +2V to +12V systems where low input bias current, low input capacitance

and fast switching speed are desired. These MOSFET devices feature very

large (almost infinite) current gain in a low frequency, or near DC, operating

environment. The ALD1106/ALD1116 are building blocks for differential

amplifier input stages, transmission gates, and multiplexer applications,

current sources and many precision analog circuits.
