FEATURES
GENERAL DESCRIPTION
The ALD1701A/ALD1701B/ALD1701/ALD1701G is a monolithic CMOS
micropower high slew rate operational amplifier 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. Supply current is 250µA maximum at 5V supply voltage. It is
manufactured with Advanced Linear Devices' enhanced ACMOS silicon
gate CMOS process.
• All parameters specified for +5V single
supply or ±2.5V dual supply systems
• Rail to rail input and output voltage ranges
• No frequency compensation required --
unity gain stable
• Extremely low input bias currents --
1.0pA typical (30pA max.)
• Idealforhighsourceimpedanceapplications
• Dual power supply ±1.0V to ±5.0V operation
• Single power supply +2.0V to +10.0V
operation
• High voltage gain -- typically 100V/mV
@ ±2.5V(100dB)
The ALD1701A/ALD1701B/ALD1701/ALD1701G is designed to offer a
trade-off of performance parameters providing a wide range of desired
specifications. It has been developed specifically for the +5V single
supply or ±1V to ±5V dual supply user and offers the popular industry
standard pin configuration of µA741 and ICL7611 types.
• Drive as low as 10KΩ load
• Output short circuit protected
• Unity gain bandwidth of 0.7MHz
• Slew rate of 0.7V/µs
• Low power dissipation
• Suitable for rugged, temperature-extreme

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 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 50pF capacitive and 10KΩ resistive loads.
