DEVICES, INC. ALD1107/ALD1117 QUAD/DUAL P-CHANNEL MATCHED PAIR MOSFET ARRAY
GENERAL DESCRIPTION APPLICATIONS The ALD1107/ALD1117 are monolithic quad/dual P-channel enhancement mode matched MOSFET transistor arrays intended for a broad
range of precision analog applications. The ALD1107/ALD1117 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 precision analog switching
and amplifying applications in -2V to -10V 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 ALD1107/
ALD1117 are building blocks for differential amplifier input stages,
transmission gates, multiplexer applications, current sources and many
precision analog circuits. •
