ALD110804/ALD110904
QUAD/DUAL N-CHANNEL ENHANCEMENT MODE EPAD?
PRECISION MATCHED PAIR MOSFET ARRAY
VGS(th)= +0.40V
GENERAL DESCRIPTION
ALD110804/ALD110904 are high precision monolithic quad/dual enhance-
ment mode N-Channel MOSFETS matched at the factory using ALD’s
proven EPAD? CMOS technology. These devices are intended for low
voltage, small signal applications. The ALD110804/ALD110904 MOSFETS
are designed and built for exceptional device electrical characteristics
matching. Since these devices are on the same monolithic chip, they also
exhibit excellent tempco tracking characteristics. They are versatile circuit
elements useful as design components for a broad range of analog appli-
cations, such as basic building blocks for current sources, differential am-
plifier input stages, transmission gates, and multiplexer applications. For
most applications, connect the V- and IC pins to the most negative volt-
age 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.
The ALD110804/ALD110904 devices are built for minimum offset voltage
and differential thermal response, and they are suited for switching and
amplifying applications in <+0.1V to +10V systems where low input bias
current, low input capacitance and fast switching speed are desired, as
these devices exhibit well controlled turn-off and sub-threshold character-
istics and can be biased and operated in the sub-threshold region. Since
these are MOSFET devices, they feature very large (almost infinite) cur-
rent gain in a low frequency, or near DC, operating environment.

PIN CONFIGURATION
ALD110804
The ALD110804/ALD110904 are suitable for use in very low operating
voltage or very low power (nanowatt), 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
