The ALD1736A/ALD1736 is designed to offer high performance for a
wide range of applications requiring very low power dissipation. It has
beendevelopedspecificallyforthe+5Vsinglebatteryor±1Vto±5Vdual
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.
• Ultra Micropower dissipation
• Suitable for rugged, temperature-extreme
environments
APPLICATIONS
• Voltage amplifier
• Voltage follower/buffer
• Charge integrator
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
ALD1736A/ALD1736 a versatile, ultra micropower operational ampli-
fier.
• Photodiode amplifier
• Data acquisition systems
• High performance portable instruments
• Biochemical probe interface
• Signal conditioning circuits
• Sensor and transducer amplifiers
• Low leakage amplifiers
• Precision Sample and Hold amplifiers
• Active filters
The ALD1736A/ALD1736, 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
