ALD310702A/ALD310702
PRECISION P-CHANNEL EPAD^® MOSFET ARRAY
QUAD NANOPOWER™ MATCHED PAIR
VGS(th)= -0.20V
GENERAL DESCRIPTION
ALD310702A/ALD310702 high precision monolithic quad P-Channel
MOSFET arrays are matched at the factory using ALD's proven EPAD^®
CMOS technology. This device is available in a quad version and is a
member of the EPAD^® Matched Pair MOSFET Family. The
ALD310702A/ALD310702 is a P-channel version of the popular
ALD110802A/ALD110802 Precision Threshold device. Together, these
two MOSFET series enable complementary precision N-Channel and P-
Channel MOSFET array based circuits.
Intended for low voltage and low power small signal applications, the
ALD310702A/ALD310702 features precision -0.20V Gate Threshold
Voltage, which enables circuit designs with very low operating voltages
such as < +0.5V power supplies where the circuits operate below the
threshold voltage of the ALD310702A/ALD310702. This feature also
enhances input/output signal operating ranges, especially in very low
operating voltage environments. With these low threshold precision
devices, a circuit with multiple cascading stages can be constructed to
operate at extremely low supply or bias voltage levels. ALD310702A/
ALD310702 also features high input impedance (2.5 x 10¹⁰Ω) and high
DC current gain (>10⁸).
ALD310702A/ALD310702 MOSFETs are designed for exceptional
matching of device electrical characteristics. The Gate Threshold Voltage
V_GS(th) is set precisely at -0.20V ^+/-0.02V, featuring a typical offset
voltage of only ^+/-0.001V (1mV). As these devices are on the same
monolithic chip, they also exhibit excellent temperature tracking
characteristics. They are versatile design components for a broad range
of precision analog applications such as basic building blocks for current
mirrors, matching circuits, current sources, differential amplifier input
stages, transmission gates, and multiplexers. These devices also excel
in limited operating voltage applications such as very low level precision
voltage-clamps. In addition to matched pair electrical characteristics,
each individual MOSFET exhibits individual well controlled manufacturing
characteristics, enabling the user to depend on tight design limits from
different production batches.
