ALD4704BSBL

Overview

The ALD4704BSBL is a quad rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices, Inc. It features MOSFET inputs with input voltage ranges extending beyond the supply rails by up to 300mV and output swings within 60mV of the rails at rated loads. The device offers a slew rate of 5V/µs, unity gain bandwidth of 2.1MHz, and extremely low input bias currents typically at 1.0pA. It operates on dual supplies from ±3.25V to ±5.0V or single supplies up to 10V. The BSBL suffix indicates a 14-pin Small Outline Plastic DIP (SOIC) package with an operating temperature range of 0°C to +70°C.

Feature Summary

• Rail-to-rail input and output voltage capabilities
• Extremely low input bias current for high source impedance applications
• Internal frequency compensation ensuring unity gain stability
• Complementary push-pull output stage design

Applications

• Voltage amplifier circuits
• High performance portable instruments
• Data acquisition systems
• Active filters and signal conditioning
• Photodiode amplifiers and charge integrators

Procurement Notes

Verify that the specific part number ALD4704BSBL corresponds to the SOIC-14 package variant. Confirm the operating temperature range matches the requirement for 0°C to +70°C. Ensure the ordering suffix 'L' is present if lead-free compliance is required. Cross-reference the manufacturer's latest datasheet version to confirm pinout compatibility and electrical specifications before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring rail-to-rail signal swing in low voltage environments. It serves as a suitable alternative to J-FET input amplifiers where lower operating voltages are utilized. Consider its high input impedance and low bias current for interfacing with high-impedance sensors. Verify that the load capacitance requirements fall within the specified limits for stable operation without external compensation.

Part Context

This device belongs to the ALD4704 family of quad operational amplifiers produced using an enhanced ACMOS silicon gate process. The family includes variants such as the ALD4704A and ALD4704B, which differ primarily in offset voltage specifications. The ALD4704 series is designed for rugged environments and offers exceptional reliability with short circuit protection and static discharge safeguards integrated into the architecture.
