ADA4000-4ARUZ-RL

Overview

The ADA4000-4ARUZ-RL is a quad precision JFET input operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 5 MHz, a slew rate of 20 V/µs, and an input offset voltage maximum of 1.70 mV. The device operates on supply voltages ranging from ±4 V to ±18 V with a typical supply current of 1.35 mA per amplifier. It utilizes a 14-lead TSSOP package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• JFET input structure providing high input impedance and very low bias current
• Unity gain stable operation with wide bandwidth and fast settling time
• Input common-mode voltage includes the positive power supply rail

Applications

• Driving analog-to-digital converter inputs
• Buffering digital-to-analog converter outputs
• High-side signal conditioning
• Instrumentation-quality photodiode amplification
• Fast precision filters including phase-locked loop filters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and reel specifications. Ensure that the component meets the required RoHS compliance standards for the intended manufacturing process. Cross-reference the part number with the latest datasheet revision to validate electrical characteristics and thermal resistance values before finalizing procurement orders.

Selection Notes

Select this component when high input impedance and low bias current are critical requirements for the signal chain. The inclusion of the positive supply rail in the common-mode voltage range makes it suitable for single-supply or high-side applications. Consider the 14-lead TSSOP package dimensions for PCB layout constraints and verify thermal dissipation capabilities within the specified operating temperature range.

Part Context

This device belongs to the ADA4000 series of low-cost, precision JFET input operational amplifiers. The series includes single-channel (ADA4000-1), dual-channel (ADA4000-2), and quad-channel (ADA4000-4) variants. These amplifiers are designed to combine precision, low power consumption, and high speed for general-purpose signal conditioning tasks in industrial and instrumentation environments.

Replacement Considerations

Direct substitutes within the same family include ADA4000-4ARZ and ADA4000-4ARZ-R7, which offer identical electrical performance but utilize a 14-Lead SOIC package instead of the TSSOP form factor.
