Replacement verdict
Compatible functional replacement candidate
The AD8058ARM and AD8052ARM-REEL are both dual high-speed voltage-feedback operational amplifiers from Analog Devices in the same 8-lead MSOP package, sharing identical pinout and similar supply and bandwidth characteristics. The AD8058ARM is a viable functional replacement candidate for the AD8052ARM-REEL in most dual-op-amp signal-chain applications, provided the designer validates the slightly different gain-bandwidth, slew-rate, and supply-current figures against the target circuit requirements.

Frequently asked questions
What are the key differences between the AD8058ARM and AD8052ARM-REEL?
The AD8058ARM is a dual, low-power, high-speed voltage feedback operational amplifier, while the AD8052ARM-REEL is a dual, high-speed, low-power rail-to-rail output voltage feedback operational amplifier. The AD8052ARM-REEL is supplied in tape-and-reel packaging for automated assembly, whereas the AD8058ARM is typically supplied in tube or tray packaging. Both are dual op amps in 8-lead MSOP packages, but they differ in output swing characteristics and specified dynamic performance.
Are the AD8058ARM and AD8052ARM-REEL pin-compatible?
Yes. Both devices are offered in an 8-lead MSOP (RM) package with the same pinout: pin 1 = OUT1, pin 2 = -IN1, pin 3 = +IN1, pin 4 = V-, pin 5 = +IN2, pin 6 = -IN2, pin 7 = OUT2, and pin 8 = V+. This common pinout allows the devices to share the same PCB land pattern, but electrical differences must still be validated before substitution.
What is the difference in output swing between the AD8058ARM and AD8052ARM-REEL?
The AD8052ARM-REEL features a rail-to-rail output stage, allowing the output to swing close to both supply rails, which is advantageous in low-voltage or single-supply applications. The AD8058ARM has a standard output stage with more limited output swing relative to the supply rails. Designers should consult the respective datasheets for exact output voltage swing specifications under their intended load and supply conditions.
Can the AD8058ARM be replaced by the AD8052ARM-REEL in an existing design?
Because both are dual high-speed voltage feedback op amps in the same 8-lead MSOP package with identical pinouts, a replacement may be possible, but it is not a drop-in substitution without verification. Key parameters such as supply voltage range, quiescent current, bandwidth, slew rate, output swing, and capacitive load stability differ between the two devices. The replacement should only be made after confirming that the AD8052ARM-REEL meets all requirements of the target circuit per the manufacturer datasheet.
What supply voltage ranges do the AD8058ARM and AD8052ARM-REEL support?
Both devices are designed for operation on dual or single supplies. The AD8058ARM operates on a supply range of ±2.5 V to ±5 V (or 5 V to 10 V single supply), while the AD8052ARM-REEL operates on a supply range of 3 V to 12 V (or ±1.5 V to ±6 V). Exact minimum and maximum supply voltages should be confirmed against the latest manufacturer datasheets before use.
Why is the AD8052ARM-REEL supplied in tape-and-reel packaging?
The "-REEL" suffix indicates tape-and-reel packaging, which is intended for high-volume automated pick-and-place assembly lines. Tape-and-reel format improves manufacturing throughput and consistency compared to tube or tray packaging. The AD8058ARM is typically supplied in tube or tray format, so packaging format is a practical difference to consider when planning production.
Do the AD8058ARM and AD8052ARM-REEL have the same bandwidth and slew rate?
No. The two devices have different specified dynamic performance. The AD8058ARM is characterized with a -3 dB bandwidth of approximately 325 MHz and a slew rate of approximately 1000 V/µs, while the AD8052ARM-REEL is characterized with a -3 dB bandwidth of approximately 110 MHz and a slew rate of approximately 145 V/µs. These values are typical and should be verified against the manufacturer datasheets for the specific test conditions.
Which device is better suited for low-power portable applications?
Both devices are low-power dual op amps, but the AD8052ARM-REEL is often preferred for low-voltage, single-supply portable designs because of its rail-to-rail output stage and 3 V minimum supply operation. The AD8058ARM offers higher bandwidth and slew rate but requires a higher minimum supply and has more limited output swing. The final choice depends on the specific power, bandwidth, and output swing requirements of the application.
