ALD1712ASAL

Overview

The ALD1712ASAL is a monolithic precision rail-to-rail operational amplifier manufactured using Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process. It operates on +5V single or ±5V dual power supplies, with characteristics specified for +5V single and ±2.5V dual systems. The device features an input stage operating up to 300mV beyond supply rails without phase reversal, offering rail-to-rail input and output voltages. Key electrical parameters include a unity gain bandwidth of 1.5MHz, a slew rate of 2.1V/µs, extremely low input bias currents of 0.01pA typical, and high voltage gain typically reaching 85V/mV at ±2.5V. It supports loads up to 4000pF capacitance at a gain of 5.

Feature Summary

• Rail-to-rail input and output operation allows implementation of numerous analog serial stages without losing operating voltage margin.
• Input stage operates linearly up to 300mV beyond the supply rails without adverse effects or phase reversals.
• On-chip offset voltage trimming eliminates the need for external nulling in most applications.
• Robust design provides suitability for temperature-extreme environments and rugged conditions.

Applications

• Voltage amplifier
• Photodiode amplifier
• Data acquisition systems
• High performance portable instruments
• Picoammeter

Procurement Notes

Verify that the ordering suffix 'SAL' corresponds to the 8-pin Small Outline Plastic DIP (SOIC) package configuration. Confirm lead-free (RoHS) compliance status as indicated by the 'L' suffix designation. Ensure the selected variant matches the required operating temperature range of 0°C to +70°C for this specific package type.

Selection Notes

Select the ALD1712ASAL when mixed digital and analog circuits share a 5V power supply. Choose this component for applications requiring high load capacitance driving capability up to 4000pF. Consider this part for designs needing symmetrical complementary output drive and extremely low input bias currents.

Part Context

The ALD1712 series includes variants such as the ALD1712APAL and ALD1712ADA, which differ primarily in package style and operating temperature ranges. The ALD1712ASAL specifically denotes the SOIC package version intended for surface mount applications within the standard commercial temperature range.
