ALD4704SBL

Overview

The ALD4704SBL is a quad rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices. It features a 14-pin Small Outline Plastic DIP (SOIC) package and operates within a temperature range of 0°C to +70°C. Key electrical specifications include a unity gain bandwidth of 2.1 MHz, a slew rate of 5.0 V/µs, and an input bias current as low as 1.0 pA typical. The device supports dual supply voltages up to ±5.3V and single supplies up to 10.6V.

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

Procurement Notes

Verify the specific ordering suffix 'SBL' corresponds to the 14-pin SOIC package variant with the commercial operating temperature range of 0°C to +70°C. Confirm lead-free (RoHS) compliance status if required for your assembly process. Ensure the selected component matches the exact pinout and thermal characteristics defined in the official datasheet before finalizing procurement.

Selection Notes

Select this component when high input impedance and wide common-mode voltage range are critical. The rail-to-rail performance allows operation at lower supply voltages compared to traditional J-FET amplifiers. Consider the 14-pin SOIC package for surface-mount applications requiring compact board space while maintaining robust drive capabilities for moderate loads.

Part Context

This part belongs to the ALD4704 family of quad operational amplifiers from Advanced Linear Devices. The series utilizes enhanced ACMOS silicon gate technology to provide high reliability and low unit cost. The SBL designation specifically identifies the plastic small outline package version intended for standard commercial temperature environments.
