ALD1106/ALD1116
QUAD/DUAL N-CHANNEL MATCHED PAIR 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 precision analog 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.
FEATURES
• Low threshold voltage of 0.7V
• Low input capacitance
• Low Vos 2mV typical
• High input impedance -- 10
