ALD1106/ALD1116
QUAD/DUAL N-CHANNEL MATCHED MOSFET ARRAY
GENERAL DESCRIPTION
APPLICATIONS
The ALD1106/ALD1116 are monolithic quad/dual N-channel enhance-
mentmodematched MOSFETtransistorarraysintendedforabroadrange
• Precision current mirrors
• Precision current sources
• Voltage choppers
• Differential amplifier input stage
• Voltage comparator
• Data converters
of precision analog applications. The ALD1106/ALD1116 offer high input
impedance and negative current temperature coefficient. The transistor
pairs are matched for minimum offset voltage and differential thermal
response, and they are designed for switching and amplifying applications
