ALD4704PBL

Overview

The ALD4704PBL is a quad rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices. It features a 5.0V/µs slew rate and a unity gain bandwidth of 2.1MHz. The device operates on dual supplies ranging from ±3.25V to ±5.0V or single supplies up to 10V, with an operating temperature range of 0°C to +70°C. Input bias current is typically 1.0pA (max 20pA), and input offset voltage is 5.0mV max. It utilizes a 14-pin PDIP package.

Feature Summary

• Rail-to-rail input and output voltage ranges
• Extremely low input bias currents
• High capacitive load capability
• Unity gain stable without external compensation

Applications

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

Procurement Notes

Verify the specific suffix 'PBL' corresponds to the 14-pin Plastic DIP package and lead-free (RoHS) compliance as defined in the manufacturer's ordering information. Confirm that the required operating temperature range aligns with the 0°C to +70°C specification for this package variant. Ensure static control procedures are followed during handling due to ESD sensitivity.

Selection Notes

Select this component when high input impedance and rail-to-rail signal swing are required within low voltage constraints. It serves as a direct alternative to J-FET input amplifiers where lower operating voltages, such as 9V batteries or ±3.25V supplies, are utilized. The symmetrical push-pull output drive makes it suitable for applications requiring both sourcing and sinking capabilities.

Part Context

This part belongs to the ALD4704 family of quad monolithic operational amplifiers. The 'PBL' designation indicates the 14-pin Plastic DIP package with lead-free construction. Other variants include the SOIC (SBL) and CERDIP (DB) packages, which may offer different temperature ranges or pin configurations while maintaining identical electrical characteristics.

Replacement Considerations
