ALD1712PAL

Overview

The ALD1712PAL is a monolithic precision operational amplifier manufactured by Advanced Linear Devices using an enhanced ACMOS silicon gate CMOS process. It features rail-to-rail input and output capabilities, allowing operation with supply voltages ranging from +5V to +10V single supply or ±2.5V to ±5.0V dual supply. The device offers a unity gain bandwidth of 1.5MHz, a slew rate of 2.1V/µs, and extremely low input bias currents of 0.01pA typical. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin PDIP package.

Feature Summary

• Rail-to-rail input and output voltage swing capability
• Linear mode operation with input voltages extending 300mV beyond supply rails
• Extremely low input bias current for high impedance applications
• Internal offset voltage trimming eliminates need for external nulling

Applications

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

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package and the commercial operating temperature range of 0°C to +70°C. Confirm RoHS compliance status as indicated by the 'L' suffix designation. Ensure the ordering part number matches the required performance grade (standard vs A/B variants) before procurement.

Selection Notes

Select this component for designs requiring full signal swing near power supply rails in low voltage environments. The rail-to-rail architecture supports mixed digital/analog systems sharing a 5V supply. Consider the 1.5MHz bandwidth and 2.1V/µs slew rate for moderate speed signal processing tasks requiring minimal phase shift.

Part Context

This device belongs to the ALD1712 family of precision operational amplifiers designed for analog serial stages where voltage margin is critical. It is available in multiple packages including SOIC and CERDIP, with the PAL variant specifically denoting the plastic DIP configuration suitable for through-hole mounting.
