GENERAL DESCRIPTION
ALD111933 are monolithic dual N-Channel MOSFETs matched at the
factory using ALD’s proven EPAD? CMOS technology. These devices are
intended for low voltage, small signal applications.
ALD111933 MOSFETs are designed and built with exceptional device
electrical characteristics matching. Since these devices are on the same
monolithic chip, they also exhibit excellent tempco tracking characteris-
tics. Each device is versatile as a circuit element and is a useful design
component for a broad range of analog applications. They are basic build-
ing blocks for current sources, differential amplifier input stages, transmis-
sion gates, and multiplexer applications. For most applications, connect
V- and N/C pins to the most negative voltage potential in the system. All
other pins must have voltages within these voltage limits.
The ALD111933 devices are built for minimum offset voltage and differen-
tial thermal response, and they are designed for switching and amplifying
applications in +3.0V 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.
The ALD111933 are suitable for use in precision applications which re-
quire 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
