Connect to V- to reduce noise PC, SC PACKAGES PA, SA PACKAGES PIN CONFIGURATION GENERAL DESCRIPTION ALD110804/ALD110904 are monolithic quad/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. The ALD110804/ALD110904 MOSFETs are designed and built for ex- ceptional device electrical characteristics matching. Since these devices are on the same monolithic chip, they also exhibit excellent tempco tracking characteristics. They are versatile circuit elements useful as design com- ponents for a broad range of analog applications, such as basic building 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 and V+ pin to the most positive voltage potential (or left open unused). All other pins must have voltages within these voltage limits. The ALD110804/ALD110904 devices are built for minimum offset voltage and differential thermal response, and they are suited for switching and amplifying applications in <+0.1V to +10V systems where low input bias current, low input capacitance and fast switching speed are desired, as these devices exhibit well controlled turn-off and sub-threshold charac- teristics and can be biased and operated in the sub-threshold region. Since these are MOSFET devices, they feature very large (almost infi- nite) current gain in a low frequency, or near DC, operating environment. The ALD110804/ALD110904 are suitable for use in very low operating voltage or very low power (nanowatt), 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 from 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 beta of the device at a drain current of 3mA and input leakage current of 30pA at 25°C is = 3mA/30pA = 100,000,000.
