ALD110814/ALD110914
QUAD/DUAL N-CHANNEL ENHANCEMENT MODE EPAD ?
PRECISION MATCHED PAIR MOSFET ARRAY
VGS(th)= +1.40V
GENERAL DESCRIPTION
ALD110814/ALD110914 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 ALD110814/ALD110914 MOSFETs are designed and built with ex-
ceptional device electrical characteristics matching. Since these devices
are on the same monolithic chip, they also exhibit excellent tempco track-
ing characteristics. Each device is versatile as a circuit element and is a
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 appli-
cations, 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.
The ALD110814/ALD110914 devices are built for minimum offset voltage
and differential thermal response, and they are designed for switching
and amplifying applications in +1.5V to +10V 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.

PIN CONFIGURATION
ALD110814
The ALD110814/ALD110914 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 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. 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.
