COMPLEMENTARY N-CHANNEL AND P-CHANNEL MOSFET
ALD1115
GENERAL DESCRIPTION
APPLICATIONS
The ALD1115 is a monolithic complementary N-channel and P-channel
transistor pair intended for a broad range of analog applications. These
enhancement-mode transistors are manufactured with Advanced Linear
Devices' enhanced ACMOS silicon gate CMOS process. It consists of
a N-channel MOSFET and a P-channel MOSFET in one package. The
ALD1115 is a dual version of the quad complementary ALD1105.
The ALD1115 offers high input impedance and negative current
temperature coefficient. The transistor pair is designed for precision
signal switching and amplifying applications in +1V to +12V systems
where low input bias current, low input capacitance and fast switching
speed are desired. Since these are MOSFET devices, they feature very
large (almost infinite) current gain in a low frequency, or near DC,
operating environment. When connected in parallel with sources, drains
and gates connected together, a CMOS analog switch can be constructed.
