ALD1101

DUAL N-CHANNEL MATCHED MOSFET PAIR

GENERAL DESCRIPTION

APPLICATIONS

The ALD1101 is a monolithic dual N-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.

• Precision current mirrors

• Precision current sources

• Analog switches

• Choppers

• Differential amplifier

input stage

• Voltage comparator

• Data converters

• Sample and Hold

• Analog inverter

The ALD1101 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, lowinputcapacitanceandfastswitchingspeedaredesired. 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 ALD1102, a dual CMOS analog switch can be constructed.

In addition, the ALD1101 is intended as a building block for differential

amplifier input stages, transmission gates, and multiplexer applications.

PIN CONFIGURATION

The ALD1101 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

specifiedat50pAatroomtemperature. Forexample, DCbetaofthedevice

at a drain current of 5mA at 25°C is = 5mA/50pA = 100,000,000.
