ALD2706
DUAL ULTRA MICROPOWER RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD2706 is a dual monolithic CMOS micropower high slew-rate
operational amplifier intended for a broad range of analog applications
using ±1V to ±6V dual power supply systems, as well as +2V to +12V
battery operated systems. All device characteristics are specified for +5V
single supply or ±2.5V dual supply systems. Supply current is 80µA
maximum at 5V supply voltage. It is manufactured with Advanced Linear
Devices' enhanced A CMOS silicon gate CMOS process.

The ALD2706 is designed to offer a trade-off of performance parameters
providing a wide range of desired specifications. It offers the popular
industry standard pin configuration.
The ALD2706 has been developed specifically for the +5V single supply or
±1V to ±6V dual supply user. Several important characteristics of the
device make application easier 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 equal to the
positive and negative supply voltages. This feature allows numerous
analog serial stages and flexibility in input signal bias levels. Secondly,
each device was designed to accommodate mixed applications where
digital and analog circuits may operate off the same power supply or
battery. Thirdly, 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 200KHz, a slew rate of 0.1V/µs, low offset voltage and temperature drift,
make the ALD2706 a versatile, micropower dual operational amplifier.
A typical ALD2706 has the capacity to process a 0.998V amplitude analog
signal with only 1.000V single supply voltage, while requiring only 0.1pA
input bias current.
