MATCHED PAIR MOSFET ARRAY  
APPLICATIONS  
GENERAL DESCRIPTION  
ALD110814/ALD110914 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.  
• Precision current mirrors  
• Precision current sources  
• Voltage choppers  
• Differential amplifier input stages  
• Discrete voltage comparators  
• Voltage bias circuits  
• Sample and Hold circuits  
• Analog inverters  
• Level shifters  
• Source followers and buffers  
• Current multipliers  
The ALD110814/ALD110914 MOSFETs are designed and built with ex-  
ceptional device electrical characteristics matching. Since these devices  
are on the same monolithic chip, they also exhibit excellent tempco track-  
ing characteristics. Each device is versatile as a circuit element and is a  
useful design component for a broad range of analog applications. They  
are basic building blocks for current sources, differential amplifier input  
stages, transmission gates, and multiplexer applications. For most appli-  
cations, 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.  
• Discrete analog multiplexers/matrices  
• Discrete analog switches  
PIN CONFIGURATION  
The ALD110814/ALD110914 devices are built for minimum offset voltage  
and differential thermal response, and they are designed for switching  
and amplifying applications in +1.5V to +10V 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.

N/C*  
The ALD110814/ALD110914 are 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 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.
