Overview
The ALD2702ASAL is a dual monolithic precision operational amplifier manufactured by Advanced Linear Devices Inc. It features rail-to-rail input and output voltage ranges, making it suitable for +5V single supply or ±2.5V to ±5V dual supply systems. The device offers a unity gain bandwidth of 1.5MHz and a slew rate of 1.9V/µs at ±2.5V. Input bias current is typically less than 1pA, with an input offset voltage of 1mV to 2mV. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin SOIC package.
Feature Summary
- Rail-to-rail input and output voltage ranges allow implementation of numerous analog serial stages without losing operating voltage margin.
- Extremely low input bias currents, typically less than 1pA, ensure high source impedance applications are not distorted.
- On-chip offset voltage trimming allows the device to be used without nulling in most applications.
- Robust design and rigorous screening make this device especially suitable for operation in temperature-extreme environments.
Applications
- Voltage follower/buffer
- Photodiode amplifier
- Data acquisition systems
- Active filters
- Picoammeter
Procurement Notes
Verify that the ordering suffix 'SAL' corresponds to the lead-free (RoHS) compliant version in the 8-pin Small Outline Plastic DIP Package (SOIC). Confirm the specific grade (A or B) matches the required offset voltage specifications. Ensure the operating environment remains within the specified 0°C to +70°C range for this package variant.
Selection Notes
Select the ALD2702ASAL when a dual precision op-amp with rail-to-rail capabilities is required for +5V single supply systems. It is ideal for applications demanding extremely low input bias currents and high voltage gain. Consider the ALD2702APAL if through-hole mounting is preferred over surface mount technology.
Part Context
The ALD2702 series includes variants such as the ALD2702A, ALD2702B, and ALD2702, differentiated primarily by offset voltage specifications. The ALD2702ASAL specifically denotes the A-grade device in a lead-free SOIC-8 package. This component belongs to a family of dual CMOS operational amplifiers designed for mixed digital/analog 5V systems.
Replacement Considerations
The ALD2702APAL serves as a direct pin-compatible alternative in an 8-pin PDIP package. For higher temperature operation, the ALD2702ADA provides a -55°C to +125°C range in a CERDIP package. Verify electrical parameters match before substitution.
FAQ
What is the maximum load capacitance the ALD2702ASAL can drive?
In a non-inverting unity gain connection, the device can drive up to 400pF of capacitive load. In an inverting unity gain mode, it can drive double that capacitance.
Does the ALD2702ASAL require external frequency compensation?
No, the device is internally compensated for unity gain stability using a novel scheme, eliminating the need for external frequency compensation components.
