Overview
The ALD2704ASAL is a dual monolithic CMOS operational amplifier with MOSFET input, manufactured by Advanced Linear Devices Inc. It features rail-to-rail input and output voltage ranges, allowing operation close to the power supply rails. The device offers a high slew rate of 5V/µs and a unity gain bandwidth of 2.1MHz. Input offset voltage is trimmed on-chip, with a maximum value of 2mV at 25°C for the A grade. Supply current is typically 6.5mA at ±5V. 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 expand signal voltage capability near supply limits
- Complementary push-pull output stage provides symmetrical drive for source and sink currents
- Internal frequency compensation ensures unity gain stability without external components
- Extremely low input bias currents minimize distortion in high source impedance applications
Applications
- Voltage follower/buffer circuits
- Photodiode amplifiers
- Charge integrators
- Active filters
- Data acquisition systems
Procurement Notes
Verify the specific grade suffix (A or B) required for your offset voltage specifications before ordering. Confirm that the SOIC-8 package matches your PCB footprint requirements. Ensure the operating environment stays within the 0°C to +70°C range specified for this package variant. Check for lead-free (RoHS) compliance if mandated by your assembly standards.
Selection Notes
Select the ALD2704ASAL when rail-to-rail performance is needed with low input bias current. Compare the A and B grades based on strict offset voltage tolerances. Consider the 5V/µs slew rate for moderate speed applications. Evaluate the capacitive load driving capability against your circuit requirements.
Part Context
This component belongs to the ALD2704 family of dual rail-to-rail CMOS operational amplifiers. It serves as an alternative to J-FET input amplifiers in lower voltage battery-operated systems. The device utilizes an enhanced ACMOS silicon gate process for reliability and cost-effectiveness.
Replacement Considerations
Direct substitutes include the ALD2704APAL (PDIP package) and ALD2704ADA (CERDIP package). Verify pinout compatibility and package dimensions when transitioning between these variants.
