ALD1701SAL

Overview

The ALD1701SAL is a monolithic CMOS micropower operational amplifier manufactured by Advanced Linear Devices. It features rail-to-rail input and output voltage ranges, allowing operation with signals equal to the supply rails. The device operates on dual supplies from ±1V to ±5V or single supplies from +2V to +10V. Key electrical specifications include a unity gain bandwidth of 700 kHz, a slew rate of 0.7 V/µs, and a maximum supply current of 250 µA at 5V. It offers high open-loop voltage gain (typically 100 V/mV) and extremely low input bias current (1 pA typical). The component is housed in an 8-pin SOIC package.

Feature Summary

• Rail-to-rail input and output voltage capability for full signal swing near supply rails
• Extremely low input bias current suitable for high source impedance applications
• Internally compensated for unity gain stability without external components
• Output short circuit protection and robust design for rugged environments

Applications

• Voltage amplifier circuits
• Photodiode amplifiers
• Data acquisition systems
• Active filters
• Picoammeters

Procurement Notes

Verify that the specific part number ALD1701SAL corresponds to the standard operating temperature range of 0°C to +70°C. Confirm the package type is the 8-pin Small Outline Plastic Dip (SOIC). Ensure compliance requirements match the 'L' suffix designation for lead-free construction. Cross-reference the manufacturer's ordering information to confirm availability and exact electrical grade specifications.

Selection Notes

Select this component when designing circuits requiring low power consumption and compatibility with single or dual low-voltage battery supplies. The rail-to-rail functionality makes it suitable for interfacing with sensors where signal swings approach the supply limits. Consider the 700 kHz bandwidth and 0.7 V/µs slew rate for moderate-speed signal processing tasks. Ensure the application does not require the extended temperature range available in the DA package variant.

Part Context

The ALD1701 series includes variants such as ALD1701A, ALD1701B, ALD1701, and ALD1701G, differentiated primarily by input offset voltage specifications. The SAL suffix indicates the 8-pin SOIC plastic package with a commercial temperature range. This family is designed to offer a trade-off between performance parameters like gain, bandwidth, and power dissipation for general-purpose analog applications.
