GENERAL DESCRIPTION
The ALD1102 is a monolithic dual P-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 ALD1102 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 ALD1101, a dual CMOS analog switch can be constructed. In
addition, the ALD1102 is intended as a building block for differential
amplifier input stages, transmission gates, and multiplexer applications.
The ALD1102 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 50pA at room temperature. For example, DC beta of the device
at a drain current of 5mA at 25°C is = 5mA/50pA = 100,000,000.
