ALD1106/ALD1116
QUAD/DUAL N-CHANNEL MATCHED MOSFET ARRAY
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.
