AD8040ARU-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The AD8040ARU-REEL7 is a quad, low-power, high-speed operational amplifier with rail-to-rail input and output capabilities. It features a 125 MHz small-signal bandwidth (G = +1), a 60 V/µs slew rate, and an 80 ns settling time to 0.1%. The device operates on supply voltages ranging from 2.7 V to 12 V, consuming only 1.3 mA per amplifier. It includes a disable pin for power management and maintains performance over an extended industrial temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive safety and vision systems
• Battery-powered instrumentation
• A-to-D drivers
• Buffering applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type matches the design requirements, as the AD8040 family is available in multiple packages including SOIC-14 and TSSOP-14. Confirm that the REEL7 suffix indicates tape-and-reel packaging suitable for automated assembly processes. Ensure the component meets the required automotive qualification standards if used in vehicle electronics.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high speed and low power are critical constraints. The rail-to-rail I/O capability allows for maximum dynamic range in single-supply systems. Consider the thermal dissipation limits in high-density designs, as the TSSOP-14 package has a thermal resistance of 120°C/W. Verify that the load conditions do not exceed the capacitive drive specifications to maintain stability.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8029/AD8030/AD8040 family of amplifiers manufactured by Analog Devices. The AD8040 specifically provides four independent amplifiers in one package, whereas the AD8029 is single-channel and the AD8030 is dual-channel. All share the same XFCB process technology for high-speed, low-power operation.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8040W is the automotive-grade version of this amplifier. Other members of the family include the AD8029 (single) and AD8030 (dual). Check pinout compatibility if substituting with other quad amplifiers, as package variations exist within the series.
