ALD1702/ALD1703
5V RAIL-TO-RAIL PRECISION OPERATIONAL AMPLIFIER
FEATURES
GENERAL DESCRIPTION
• Rail-to-rail input and output voltage ranges
• All parameters specified for +5V single
supply or ±2.5V dual supply systems.
• High load capacitance capability --
4000pF typical
• No frequency compensation required --
unity gain stable
The ALD1702A/ALD1702B/ALD1702/ALD1703 is a monolithic opera-
tional amplifier intended primarily for a wide range of analog applications
in +5V single power supply and ±5V dual power supply systems as well
as +4V to +10V battery operated systems. All device characteristics are
specified for +5V single supply or ±2.5V dual supply systems. It is
manufactured with Advanced Linear Devices' enhanced ACMOS silicon
gate CMOS process.
• Extremely low input bias currents --
The ALD1702A/ALD1702B/ALD1702/ALD1703 is designed to offer a
balanced trade-off of performance parameters providing a wide range of
desired specifications. It has been developed specifically with the 5V
single supply or ±2.5 dual supply user in mind and offers the industry
pin configuration of µA741 and ICL7611 types.
1.0pA typical (30pA max.)
• Ideal for high source impedance applications
• Dual power supply ±2.5V to ±5.0V operation
• Single power supply +5V to +10V operation
• High voltage gain -- typically 85V/mV
@ ±2.5V and 250V/mV @ ±5.0V
• Drive as low as 2KΩ load with 5mA
drive current
• Output short circuit protected
• Unity gain bandwidth of 1.5MHz (1MHz min.)
• Slew rate of 2.1V/µs (1.4V/µs min.)
• Low power dissipation
Several important characteristics of the device make many applications
easy to implement for these supply voltages. First, the operational
amplifier can operate with rail to rail input and output voltages. This
feature allows numerous analog serial stages to be implemented without
losing operating voltage margin. Second, the device was designed to
accommodate mixed applications where digital and analog circuits may
work off the same 5V power supply. Third, the output stage can drive
up to 400pF capacitive and 5KΩ resistive loads in non-inverting unity
gain connection and double the capacitance in the inverting unity gain
mode.
• Suitable for rugged, temperature-extreme
environments
APPLICATIONS
• Voltage amplifier
• Voltage follower/buffer
• Charge integrator
• Photodiode amplifier
• Data acquisition systems
• High performance portable instruments
• Signal conditioning circuits
• Sensor and transducer amplifiers
• Low leakage amplifiers
• Active filters
These features, coupled with extremely low input currents, high voltage
gain, useful bandwidth of 1.5MHz, slew rate of 2.1V/µs, low power
dissipation, low offset voltage and temperature drift, make the ALD1702A/
ALD1702B/ALD1702/ALD1703 a truly versatile, user friendly, operational
amplifier.
The ALD1702A/ALD1702B/ALD1702/ALD1703 is designed and
fabricated with silicon gate CMOS technology, and offers 1pA typical
input bias current. On-chip offset voltage trimming allows the device to
be used without nulling in most applications. The device offers typical
offset drift of less than 7µV/°C which eliminates many trim or temperature
compensation circuits. For precision applications, it is designed to settle
to 0.01% in 8µs. Additionally, robust design and rigorous screening make
this device especially suitable for operation in temperature-extreme
environments and rugged conditions.
• Sample/Hold amplifier
• Picoammeter
• Current to voltage converter
• Coaxial cable driver
