Precision "Matched Pair" N-Channel Mosfet Array
|
|
Sunnyvale, CA., February 10, 2004 - Advanced Linear Devices, Inc., announces the ALD1121E (dual) and ALD1123E (quad) precision, matched MOSFET array designed for superior performance in most electrically balanced circuit applications. These monolithic N-channel MOSFET transistor matched pairs are manufactured using ALD's exclusive E-trim™ process, which assures tight matching and tracking of on-resistance, threshold voltage and drain-on current operating characteristics. ALD MOSFET arrays feature very low input currents and consequently, very high input impedance - typically 1012 Ohms. Power supply requirements range from 1.2V to 10V. Although not required, both devices can be optionally e-trimmed by the user as an active in-circuit element via user designed interface circuitry and an ALD EPAD® programming module.
The ALD1121E/ALD1123E is typically matched to within 1mV offset voltage. When used in precision current mirror or current multiplier applications, ALD matched pair MOSFET arrays can provide a current source with a 100nA to 3mA range and either positive, negative or zero temperature coefficient matching characteristics. They are also ideally suited for a variety of other balance-circuit applications in low voltage sensors, transducer biasing circuits, precision gain pre-amplifiers, portable instruments and others demanding long-term, reliable performance.
The dual ALD1121E has two separate source pins and is available in an 8-pin plastic dip or SOIC package for all standard 0-70°C applications. The quad ALD1123E has four separate source pins and is available in a 16-pin footprint. Optional industrial and military temperature range devices are available in a variety of ceramic packages. Pricing, for the standard temperature range MOSFET pairs, ranges from $0.75 to $1.24 each in 1000 piece quantities. Prototype and small volume quantities are available from stock.
