GENERAL DESCRIPTION
DUAL N-CHANNEL MATCHED MOSFET PAIR
APPLICATIONS
ALD1101A/ALD1101B
ALD1101
The ALD1101 is a monolithic dual N-channel matched transistor pair
intended for a broad range of analog applications. These enhancement-
mode transistors are manufactured with Advanced Linear Devices' en-
hanced ACMOS silicon gate CMOS process.
The ALD1101 offers high input impedance and negative current tempera-
ture coefficient. The transistor pair is matched for minimum offset voltage
and differential thermal response, and it is designed for switching and
amplifying applications in +2V 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
used with an ALD1102, a dual CMOS analog switch can be constructed.

In addition, the ALD1101 is intended as a building block for differential
amplifier input stages, transmission gates, and multiplexer applications.
PIN CONFIGURATION
The ALD1101 is suitable for use in precision applications which require
very high current gain, beta, such as current mirrors and current sources.
