ALD1704BSAL

Overview

The ALD1704BSAL is a CMOS monolithic operational amplifier with MOSFET input, manufactured by Advanced Linear Devices Inc. It features rail-to-rail input and output voltage ranges, allowing operation with low supply voltages such as ±3.25V to ±5V or +6.5V to +10V single supply. The device offers a slew rate of 5.0 V/µs, unity gain bandwidth of 2.1 MHz, and extremely low input bias current of 1.0 pA typical. It provides symmetrical push-pull output drives capable of sourcing and sinking up to 10 mA. The part is housed in an 8-pin Small Outline Plastic DIP (SOIC) package.

Feature Summary

• Rail-to-rail input and output voltage ranges for extended signal swing capability
• Extremely low input bias currents suitable for high source impedance applications
• High capacitive load driving capability without external compensation
• Symmetrical push-pull output stage design

Applications

• Voltage amplifier circuits
• Voltage follower/buffer configurations
• Charge integrator systems
• Photodiode amplifiers
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'SAL' corresponds to the 8-pin Small Outline Plastic DIP package when ordering. Confirm that the 'B' designation aligns with the required offset voltage specifications for your application. Ensure static control procedures are followed during handling due to ESD sensitivity. Cross-reference the manufacturer's ordering information to validate lead-free status if RoHS compliance is mandatory.

Selection Notes

Select this component for applications requiring rail-to-rail performance at low operating voltages. It serves as a direct alternative to JFET input amplifiers where lower power consumption is critical. Consider the 5.0 V/µs slew rate and 2.1 MHz bandwidth for general-purpose analog signal processing. The internal trimming eliminates the need for external nulling in many standard configurations.

Part Context

This device belongs to the ALD1704 family of rail-to-rail CMOS operational amplifiers from Advanced Linear Devices Inc. The family includes variants like ALD1704A, ALD1704B, and ALD1704G, differentiated primarily by offset voltage specifications and temperature ranges. The ALD1704BSAL specifically denotes the B-grade offset performance within the SOIC-8 plastic package format.

Replacement Considerations

The datasheet identifies the ALD1704A, ALD1704B, and ALD1704G as functional equivalents within the same family. Substitution depends on matching the specific offset voltage requirements and ensuring the package type compatibility.
