ALD1105
DUAL N-CHANNEL AND DUAL P-CHANNEL MATCHED PAIR MOSFET
GENERAL DESCRIPTION The ALD1105 is a monolithic dual N-channel and dual P-channel complementary matched transistor pair intended for a broad range of analog applications. These enhancement-mode transistors are manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process. It consists of an ALD1116 N-channel MOSFET pair and an ALD1117 P-channel MOSFET pair in one package. The ALD1105 is a low drain current, low leakage current version of the ALD1103. The ALD1105 offers high input impedance and negative current temperature coefficient. The transistor pair is matched for minimum offset voltage and differential thermal response, and it is designed for precision signal switching and amplifying applications in +1V to +12V 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. When used in complementary pairs, a dual CMOS analog switch can be constructed. In addition, the ALD1105 is intended as a building block for differential amplifier input stages, transmission gates, and multiplexer applications. The ALD1105 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 c……
