ALD1115
COMPLEMENTARY N-CHANNEL AND P-CHANNEL MOSFET
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.
In addition, the ALD1115 is intended as a building block for CMOS
inverters, differential amplifier input stages, transmission gates, and
multiplexer applications.
The ALD1115 is suitable for use in precision applications which require
very high current gain, beta, such as current mirrors and current sources.
The high input impedance and the high DC current gain of the field effect
transistors result in extremely low current loss through the control gate.
The DC current gain is limited by the gate input leakage current, which
is specified at 30pA at room temperature. V+ is connected to the
substrate, which is the most positive voltage potential of the ALD1115,
usually SP(5). Similarly, V- is connected to the most negative voltage
potential of the ALD1115, usually SN (1).
