ALD2711
DUAL MICROPOWER PRECISION RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
FEATURES
The ALD2711A/ALD2711B/ALD2711 is a dual monolithic CMOS • Designed and characterized for 5V operation
micropower precision high slew rate operational amplifier intended for • Linear mode operation with input voltages
a broad range of analog applications using ±1V to ±5V dual power
supply systems, as well as +2V to +10V battery operated systems. All • Output voltages to within 2mV of power supply
device characteristics are specified for +5V single supply or ±2.5V rails when driving a high impedance load
300mV beyond supply rails
dual supply systems. Typical supply current is 200µA at 5V supply • Unity gain stable
voltage. It is manufactured with Advanced Linear Devices' enhanced • Extremely low input bias currents -- 0.01pA
ACMOS silicon gate CMOS process.
• Dual power supply ±1.0V to ±5.0V
• Single power supply +2V to +10V
The ALD2711A/ALD2711B/ALD2711 has been developed specifically • High voltage gain
for the +5V single supply or ±1V to ±5V dual supply user and has an • Output short circuit protected
input stage that operates to +300mV above and -300mV below the • Unity gain bandwidth of 0.7MHz
supply voltages with no adverse effects and/or phase reversals.
• Slew rate of 0.7V/µs
• Low power dissipation
Several important characteristics of the device make application easier • Symmetrical complementary output drive
to implement at those voltages. First, each operational amplifier can
operate with rail to rail input and output voltages. This means the
signal input voltage and output voltage can be at the positive and
negative supply voltages. This feature allows numerous analog serial
stages and flexibility in input signal bias levels. Second, each 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 50pF capacitive and
10KΩ resistive loads.
• Suitable for rugged, temperature-extreme
environments
APPLICATIONS
• Voltage follower/buffer/amplifier
• Charge integrator
• Photodiode amplifier
• Data acquisition systems
• High performance portable
instruments
• Signal conditioning circuits
• Sensor and transducer amplifiers
• Low leakage amplifiers
• Active filters
• Sample/Hold amplifier
• Picoammeter
These features, combined with extremely low input currents, high open
loop voltage gain, high useful bandwidth, and slew rate make the
LD2711A/ALD2711B/ALD2711 a versatile, micropower operational
amplifier.
The ALD2711A/ALD2711B/ALD2711 with on-chip offset voltage trimming
allows the device to be used without nulling in most applications.
Additionally, robust design and rigorous screening make this device
especially suitable for operation in temperature-extreme environments and
rugged conditions.
• Current to voltage converter
The unique characteristics of the ALD2711A/ALD2711B/ALD2711 are
modeled in an available macromodel.
