Overview
The ALD1704ASAL is a single-channel CMOS operational amplifier featuring rail-to-rail input and output voltage ranges. It operates on dual supplies from ±3.25V to ±5.0V or single supplies up to 10V, consuming approximately 4.5mA at ±5V. Key electrical parameters include a slew rate of 5.0V/µs, unity gain bandwidth of 2.1MHz, and typical input bias current of 1.0pA. The device offers high open-loop voltage gain (typically 150V/mV) and settles to 0.1% in 2.0µs. It is housed in an 8-pin SOIC package with an operating temperature range of 0°C to +70°C.
Feature Summary
- Rail-to-rail input and output voltage ranges allow operation near supply rails.
- Extremely low input bias currents suitable for high source impedance applications.
- Unity gain stable without external frequency compensation.
- High capacitive load driving capability up to 4000pF.
Applications
- Voltage amplifier
- Voltage follower/buffer
- Charge integrator
- Photodiode amplifier
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'SAL' corresponds to the 8-pin Small Outline Plastic DIP (SOIC) package variant. Confirm RoHS compliance status as indicated by the 'L' suffix designation. Ensure the operating environment remains within the specified 0°C to +70°C range for this package type. Cross-reference the manufacturer's ordering information to validate lead-free specifications against project requirements.
Selection Notes
Select this component when rail-to-rail signal swing is required from low-voltage single or dual supplies. It serves as a direct alternative to JFET input amplifiers where lower power consumption and higher input impedance are prioritized. The symmetrical push-pull output stage supports both sourcing and sinking currents effectively. Consider the 2.1MHz bandwidth and 5V/µs slew rate for moderate-speed signal processing tasks.
Part Context
This device belongs to the ALD1704 family of monolithic CMOS operational amplifiers manufactured using Advanced Linear Devices' ACMOS silicon gate process. The family includes variants such as ALD1704A, ALD1704B, ALD1704, and ALD1704G, differentiated primarily by offset voltage specifications. The ALD1704ASAL specifically denotes the A-grade version in the SOIC-8 surface mount package.
Replacement Considerations
Public confirmed substitute part numbers: ALD1704BSAL, ALD1704SAL, ALD1704GSAL.
FAQ
