ALD1107/ALD1117
QUAD/DUAL P-CHANNEL MATCHED MOSFET ARRAY
APPLICATIONS
GENERAL DESCRIPTION
The ALD1107/ALD1117 are monolithic quad/dual P-channel enhance-
mentmodematchedMOSFETtransistorarraysintendedforabroadrange
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 +12V systems where low input bias
current, lowinputcapacitanceandfastswitchingspeedaredesired. These
MOSFET devices feature very large (almost infinite) current gain in a low
frequency,ornearDCoperatingenvironment.TheALD1107/ALD1117are
builiding blocks for differential amplifier input stages, transmission gates,
multiplexer applications, current sources, current mirrors and other preci-
sion analog circuits.
