ADA4092-4ARUZ

Overview

The ADA4092-4ARUZ is a quad micropower operational amplifier featuring rail-to-rail inputs and outputs. It operates from a single supply of 3 V to 30 V or dual supplies of ±1.5 V to ±15 V. Key electrical specifications include a gain bandwidth product of 1.4 MHz, a slew rate of 0.4 V/µs, and a maximum input offset voltage of 1.5 mV. The device draws 200 µA per amplifier and includes overvoltage protection (OVP) allowing inputs to exceed supply rails safely without phase reversal.

Feature Summary

• Features rail-to-rail input and output capabilities for extended dynamic range in single-supply systems.
• Includes overvoltage protection (OVP) that allows input voltages to exceed supply rails without latch-up or phase reversal.
• Provides low power consumption with a supply current of 200 µA per amplifier.

Applications

• Industrial process control
• Battery-powered instrumentation
• Power supply control and protection
• Telecommunications equipment
• Remote sensors

Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number ADA4092-4ARUZ indicates a tube package, while the -RL suffix denotes reel packaging. Confirm RoHS compliance status as indicated by the Z suffix in related variants. Ensure the selected package option matches the intended PCB assembly requirements for the 14-lead TSSOP form factor.

Selection Notes

Select this component for applications requiring high precision with low power consumption in single-supply environments. The wide input voltage range and OVP make it suitable for interfacing with transducers having wide output ranges. Consider the 1.4 MHz bandwidth and 0.4 V/µs slew rate for moderate-speed signal conditioning tasks where rail-to-rail performance is critical.

Part Context

The ADA4092-4ARUZ belongs to Analog Devices' family of 30 V, low-power operational amplifiers. It is the quad-channel version of the ADA4092 series, sharing architectural similarities with other members like the ADA4091-2 and ADA4091-4. The device is designed for industrial and portable applications requiring robust operation across the extended industrial temperature range of −40°C to +125°C.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the ADA4092-4ARUZ-RL for reel packaging. Other quad op-amps in the 30 V low-power category may require verification of electrical parameter compatibility, particularly regarding offset voltage and bandwidth specifications.

FAQ

How does the overvoltage protection function?

The input stage allows the input voltage to exceed either supply rail safely without causing phase reversal or latch-up, utilizing internal DIAC structures and series resistors for protection.

What is the maximum supply voltage?

The device supports a maximum supply voltage of 36 V, operating reliably from single supplies up to 30 V or dual supplies up to ±15 V.
