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.
FEATURES
• Low threshold voltage of -0.7
• Low input capacitance
• Low V
• High input impedance -- 10
• Low input and output leakage currents
• Negative current (I
• Enhancement-mode (normally off)
• DC current gain 10
• Low input and output leakage currents
