Overview
The ALD1702PAL is a single-channel, rail-to-rail precision operational amplifier manufactured by Advanced Linear Devices using enhanced ACMOS silicon gate CMOS technology. Designed for +5V single supply or ±2.5V dual supply systems, it features a unity gain bandwidth of 1.5 MHz and a slew rate of 2.1 V/µs. The device offers extremely low input bias current (1 pA typical) and high voltage gain (85 V/mV at ±2.5V). It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin PDIP package.
Feature Summary
- Rail-to-rail input and output voltage ranges enable full signal swing without losing operating margin.
- Extremely low input bias currents (1 pA typical) make the device ideal for high source impedance applications.
- Internally compensated for unity gain stability with no external frequency compensation required.
- High load capacitance capability allows driving up to 4000 pF typical capacitive loads.
Applications
- Voltage amplifier
- Photodiode amplifier
- Data acquisition systems
- Active filters
- Picoammeter
Procurement Notes
Verify that the ordering suffix 'PAL' corresponds to the 8-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status as indicated by the 'L' suffix in the manufacturer's ordering information. Ensure static control procedures are followed during handling due to ESD sensitivity.
Selection Notes
Select this component when a rail-to-rail operational amplifier is required for +5V single-supply or ±2.5V dual-supply systems. It is suitable for mixed digital/analog environments sharing a 5V power supply. Consider this part for applications demanding low input bias current and high input impedance, such as sensor interfaces or charge integrators.
Part Context
The ALD1702PAL belongs to the ALD1702 family of monolithic operational amplifiers from Advanced Linear Devices. This series includes variants like the ALD1702A, ALD1702B, and ALD1703, which share similar pin configurations compatible with µA741 and ICL7611 types but offer superior CMOS performance characteristics.
Replacement Considerations
The datasheet notes compatibility with the industry pin configuration of µA741 and ICL7611 types. However, specific substitute part numbers are not explicitly listed in the provided documentation.
FAQ
What is the maximum load capacitance the ALD1702PAL can drive?
The device can typically drive 400 pF of external load capacitance in a unity gain buffer configuration without stability problems. In the inverting unity gain configuration, it can drive up to 800 pF.
Does the ALD1702PAL require external frequency compensation?
No, the ALD1702PAL is internally compensated for unity gain stability using a novel scheme that does not use a nulling resistor, eliminating the need for external frequency compensation components.
