GENERAL DESCRIPTION

The ALD1107/ALD1117 are monolithic quad/dual P-channel enhance-

ment 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 +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 ALD1107/ALD1117 are

builiding blocks for differential amplifier input stages, transmission gates,

multiplexer applications, current sources, current mirrors and other preci-

sion analog circuits.
