ALD2736A/ALD2736
PRECISION DUAL ULTRA MICROPOWER CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD2736A/ALD2736 is a precision dual low-cost high-slew-rate
high-performance ultra micropower monolithic CMOS operational am-
plifier intended for a broad range of analog applications using ±1V to
±5V dual power supply systems, as well as +2V to +10V battery
operated systems. All device characteristics are specified for +5V
single supply or ±2.5V dual supply systems. Typical supply current is
25µA per op amp at 5V supply voltage. It is manufactured with
Advanced Linear Devices' enhanced EPAD® silicon gate CMOS pro-
cess.
The ALD2736A/ALD2736 is designed to offer high performance for a
wide range of applications requiring very low power dissipation. It has
been developed specifically for the +5V single battery or ±1V to ±5V dual
battery user and offers the popular industry standard single operational
amplifier pin configuration.
Several important characteristics of the device make application easier
to implement at those voltages. First, the operational amplifier can
operate with rail to rail input and output voltages. This means the signal
input voltage and output voltage can be close to or equal to the positive
and negative supply voltages. This feature allows numerous analog
serial stages and flexibility in input signal bias levels. Second, the
device was designed to accommodate mixed applications where digital
and analog circuits may operate off the same power supply or battery.
Third, the output stage can typically drive up to 25pF capacitive and
20KΩ resistive loads.
These features, combined with extremely low input currents, high open
loop voltage gain of 100V/mV, useful bandwidth of 400KHz, a slew rate
of 0.17V/µs, low offset voltage and temperature drift, make the
ALD2736A/ALD2736 a versatile, micropower operational amplifier.
The ALD2736A/ALD2736, designed and fabricated with silicon gate
CMOS technology, offers on-chip offset voltage trimming, allowing the
device to be used without nulling in most applications. It is also
designed to offer tolerance to over-voltage input spikes of 300mV
beyond supply rails, high open loop voltage gain, and robust operation
at temperature extremes. Additionally, robust design and rigorous
screening make this device especially suitable for operation in tempera-
ture-extreme environments and rugged conditions.
