AD8605ACBZ-REEL7

Overview

The AD8605ACBZ-REEL7 is a single-channel, precision, low-noise CMOS operational amplifier with rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical specifications include a maximum offset voltage of 65 µV, a maximum input bias current of 1 pA, and a voltage noise density of 8 nV/√Hz at 1 kHz. The device features a unity-gain bandwidth product of 10 MHz and a slew rate of 5 V/µs. It is housed in a 5-ball WLCSP package and is specified for operation over an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Utilizes patented DigiTrim trimming technique to achieve superior precision without laser trimming.
• Provides rail-to-rail input and output swing capability for maximum dynamic range.
• Exhibits no phase reversal even when input voltages exceed the supply rails by more than 2 V.
• Features very low input bias current and low noise characteristics suitable for high-impedance sensor applications.

• Audio

Procurement Notes

Verify that the component matches the specific AD8605ACBZ-REEL7 designation, ensuring the CB suffix corresponds to the 5-ball WLCSP package. Confirm the reel packaging format aligns with automated assembly requirements. Cross-reference the manufacturer's latest datasheet revision to ensure compliance with updated electrical specifications and absolute maximum ratings before finalizing procurement.

Selection Notes

Select this component for designs requiring high DC precision combined with wide signal bandwidth in a minimal footprint. The low input bias current makes it ideal for interfacing with high-impedance sources such as photodiodes or piezoelectric sensors. Ensure the application environment stays within the specified -40°C to +125°C operating temperature range and that the supply voltage remains between 2.7 V and 5.5 V.

Part Context

This part belongs to the AD860x family of precision, low-noise, CMOS, rail-to-rail input/output operational amplifiers manufactured by Analog Devices Inc. The family includes the dual-channel AD8606 and quad-channel AD8608 variants. These amplifiers are designed for applications demanding high accuracy and speed in single-supply systems, leveraging proprietary trimming technology for enhanced performance stability.

Replacement Considerations

Direct functional substitutes within the same family include the AD8606 (dual channel) and AD8608 (quad channel), though pin counts differ. Other single-channel precision amplifiers may require verification of pin compatibility, package dimensions, and specific electrical parameter alignment against the original design requirements.
