ALD2702BPAL

Overview

The ALD2702BPAL is a dual monolithic precision operational amplifier manufactured by Advanced Linear Devices Inc. It features rail-to-rail input and output voltage ranges, making it suitable for +5V single supply or ±5V dual power supply systems. The device offers a unity gain bandwidth of 1.5MHz and a slew rate of 1.9V/µs. Input bias current is typically less than 1pA, with an offset voltage drift under 7 µV/°C. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin Plastic DIP package.

Feature Summary

• Rail-to-rail input and output voltage ranges
• Extremely low input bias currents below 1.0pA typical
• High load capacitance capability driving up to 4000pF
• Unity gain stable without frequency compensation

Applications

• Voltage follower/buffer
• Photodiode amplifier
• Data acquisition systems
• Active filters
• Picoammeter

Procurement Notes

Verify the specific ordering suffix 'PAL' corresponds to the 8-pin Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as indicated by the manufacturer's documentation. Ensure compatibility with standard through-hole PCB mounting techniques required for this package style.

Selection Notes

Select this component when high source impedance applications require minimal input bias current loading. The rail-to-rail performance allows full signal swing utilization in low-voltage single-supply designs. Verify that the 1.5MHz bandwidth meets the system's frequency response requirements and that the PDIP-8 package fits the available board space constraints.

Part Context

This part belongs to the ALD2702 family of dual precision CMOS operational amplifiers. The BPAL suffix specifically denotes the B-grade version packaged in an 8-pin Plastic DIP format. This series is designed for mixed digital/analog environments where a common 5V supply is utilized.

Replacement Considerations

Direct substitutes include ALD2702APAL and ALD2702PAL from the same manufacturer family.
