PRECISION MATCHED PAIR MOSFET ARRAY
GENERAL DESCRIPTION
ALD110808A/ALD110808/ALD110908A/ALD110908 are high precision
monolithic quad/dual enhancement mode N-Channel MOSFETs matched
at the factory using ALD’s proven EPAD® CMOS technology. These de-
vices are intended for low voltage, small signal applications.
These MOSFET devices are built on the same monolithic chip, so they
exhibit excellent temperature tracking characteristics. They are versatile
as circuit elements and are useful design component for a broad range of
analog applications. They are basic building blocks for current sources,
differential amplifier input stages, transmission gates, and multiplexer
applications. For most applications, connect the V- and IC pins to the most
negative voltage in the system and the V+ pin to the most positive voltage.
All other pins must have voltages within these voltage limits at all times.
ALD110808/ALD110908 devices are built for minimum offset voltage and
differential thermal response, and they are suited for switching and ampli-
fying applications in +1.0V to +10V (+/- 5 V) systems where low input bias
current, low input capacitance and fast switching speed are desired. As
these are MOSFET devices, they feature very large (almost infinite) cur-
rent gain in a low frequency, or near DC, operating environment.
These devices are 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 from 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. For example, DC beta of the
device at a drain current of 3mA and input leakage current of 30pA at
25°C is = 3mA/30pA = 100,000,000.
