ALD4706BSBL

Overview

The ALD4706BSBL is a quad monolithic CMOS ultra micropower high slew-rate operational amplifier manufactured by Advanced Linear Devices. It operates on dual supplies from ±1V to ±5V or single supplies from +2V to +10V. Key electrical specifications include a unity gain bandwidth of 200 kHz, a slew rate of 0.17 V/µs, and an input bias current as low as 0.1 pA. The device features rail-to-rail input and output voltage ranges, high open-loop voltage gain of up to 300 V/mV, and power dissipation of 20 µA per op amp. It is housed in a 14-pin Small Outline Plastic DIP (SOIC) package with an operating temperature range of 0°C to +70°C.

Feature Summary

• Rail-to-rail input and output voltage ranges for maximum dynamic signal swing
• Ultra micropower operation with extremely low input bias currents suitable for high source impedance applications
• Unity gain stable design with internal frequency compensation
• Output short circuit protection for robust performance

Applications

• Voltage follower/buffer/amplifier circuits
• Charge integrator and photodiode amplifier configurations
• Data acquisition systems and sensor/transducer amplifiers
• Active filters and sample/hold amplifiers
• Picoammeter and current to voltage converter designs

Procurement Notes

Verify the specific suffix 'BSBL' corresponds to the SOIC-14 package variant within the 0°C to +70°C commercial temperature grade. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as leaded versions may be available upon request. Ensure static control procedures are followed during handling due to ESD sensitivity inherent to CMOS technology.

Selection Notes

Select this component when designing battery-operated systems requiring minimal quiescent current consumption alongside rail-to-rail signal processing capabilities. It serves as a direct pin-compatible alternative to industry standard LM324 and ICL7641 types while offering superior input bias current performance. Consider the 0.17 V/µs slew rate limitation for high-frequency signal integrity requirements.

Part Context

The ALD4706 series belongs to Advanced Linear Devices' portfolio of enhanced ACMOS silicon gate CMOS operational amplifiers. This family includes variants such as the ALD4706A and ALD4706B, differentiated primarily by offset voltage specifications. The BSBL designation identifies the specific package type and temperature rating within this broader product line.

Replacement Considerations

The datasheet explicitly states compatibility with LM324 and ICL7641 pin configurations. Verify functional equivalence regarding supply voltage ranges and output drive capabilities before substitution.
