ALD1712BPAL

Overview

The ALD1712BPAL is a monolithic precision operational amplifier manufactured using an enhanced ACMOS silicon gate CMOS process. It supports +5V single supply or ±2.5V dual supply systems, with rail-to-rail input and output capabilities extending within 300mV of the rails without phase reversal. The device features a unity gain bandwidth of 1.5MHz, a slew rate of 2.1V/µs, and extremely low input bias currents typically at 0.01pA. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin Small Outline Plastic DIP (SOIC) package.

Feature Summary

• Rail-to-rail input and output operation allows full signal swing near power supply limits.
• Extremely low input bias current ensures minimal distortion for high-impedance sources.
• Internal frequency compensation provides stability without external components.
• On-chip offset voltage trimming eliminates the need for nulling circuits.

Applications

• Voltage amplifier
• Photodiode amplifier
• Data acquisition systems
• Picoammeter
• Active filters

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status as indicated by the ordering information. Ensure the design accounts for the specified operating supply voltages and load capacitance limits to maintain stability.

Selection Notes

Select this component when designing for single-supply 5V or dual-supply ±2.5V environments requiring rail-to-rail performance. It is suitable for applications demanding low power dissipation and high input impedance. Consider the 8-pin SOIC package constraints and verify that the required operating temperature falls within the commercial range.

Part Context

This part belongs to the ALD1712 family of rail-to-rail precision operational amplifiers from Advanced Linear Devices. The family includes variants like the ALD1712A and ALD1712B, which share core electrical characteristics but may differ in screening levels or specific parameter tolerances. The BPAL designation identifies the specific package and temperature grade within this product line.

Replacement Considerations

Check datasheets for other rail-to-rail CMOS op-amps offering similar 1.5MHz bandwidth and low bias current. Verify pin compatibility and ensure replacement devices support the same ±2.5V to ±5V dual supply or +5V to +10V single supply requirements.

FAQ
