ALD4704ASBL

Overview

The ALD4704ASBL is a quad rail-to-rail CMOS operational amplifier manufactured by Advanced Linear Devices. It features a MOSFET input stage with rail-to-rail input and output voltage ranges, allowing operation near supply rails. Key electrical parameters include a gain-bandwidth product of 2.1 MHz, a slew rate of 5 V/µs, and an input offset voltage of up to 5 mV at 25°C. The device operates on dual supplies from ±3.25 V to ±5 V or single supplies up to 10 V, drawing 13 mA of supply current. It is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Rail-to-rail input and output voltage ranges for expanded signal swing
• High slew rate of 5.0 V/µs with unity gain stability
• Extremely low input bias currents typical of 1.0 pA
• Complementary push-pull output drive capable of symmetrical sourcing and sinking

Applications

• Voltage amplifier circuits
• Voltage follower and buffer applications
• Charge integrator designs
• Photodiode amplifiers
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'SBL' corresponds to the SOIC-14 package and commercial temperature grade when ordering. Confirm RoHS compliance status as indicated by the 'L' suffix in the manufacturer's documentation. Ensure the selected variant matches the required operating temperature range for the intended application environment.

Selection Notes

Select this component for applications requiring high input impedance and wide dynamic range without external nulling. The rail-to-rail capability makes it suitable for low-voltage battery-powered systems. Consider the 2.1 MHz bandwidth and 5 V/µs slew rate for moderate-speed signal processing tasks where precision and low noise are prioritized over ultra-high speed performance.

Part Context

This part belongs to the ALD4704 family of quad operational amplifiers. Variants such as ALD4704APBL and ALD4704ADB offer different packaging options like PDIP-14 and CERDIP-14, along with extended temperature ranges. The ALD4704ASBL specifically denotes the SOIC-14 surface-mount version within the commercial temperature grade segment of this product line.

Replacement Considerations

Direct substitutes include other quad rail-to-rail CMOS op-amps with similar pinouts and electrical characteristics. Verify that replacement parts maintain comparable input bias currents and slew rates to ensure circuit compatibility.
