Frequently asked questions
What is the difference between AD8170ARZ and AD8170ARZ-RL?
Both parts are the same AD8170 8-lead SOIC (R-8) multiplexer-amplifier die and specification. The suffix difference is packaging format: AD8170ARZ is supplied in tube/rail packaging, while AD8170ARZ-RL is supplied in tape-and-reel packaging for automated assembly. Electrical performance and temperature grade are identical.
Are AD8170ARZ and AD8170ARZ-RL electrically and functionally interchangeable?
Yes. Both are the same AD8170 device in the same 8-lead SOIC package with identical pinout and specified performance, so they are interchangeable in a design. The only difference is the shipping container (tube vs. tape-and-reel), which affects handling and pick-and-place equipment, not circuit behavior.
What is the AD8170 and what are its key verified specifications?
The AD8170 is a low-power, high-speed 2:1 multiplexer-amplifier from Analog Devices. Verified datasheet specifications include: -3 dB bandwidth of 250 MHz (G = +2), 0.1 dB flatness to 70 MHz, slew rate of 1000 V/µs, 0.02% / 0.04° differential gain/phase, supply operation from ±5 V to ±15 V (or single supply), and low power consumption of 7.5 mA typical. It is specified for the industrial temperature range of -40°C to +85°C.
What package does the AD8170ARZ use and is it RoHS compliant?
The AD8170ARZ and AD8170ARZ-RL are both supplied in the 8-lead SOIC package (R-8 suffix). The "Z" suffix in the part number denotes RoHS-compliant, lead-free construction per Analog Devices' ordering guide.
Which packaging should I choose, AD8170ARZ or AD8170ARZ-RL?
Choose AD8170ARZ (tube/rail) for manual handling, prototyping, or low-volume assembly. Choose AD8170ARZ-RL (tape-and-reel) for automated pick-and-place production lines, as the reel format is required by most SMT assembly equipment and supports higher-volume manufacturing.
Do AD8170ARZ and AD8170ARZ-RL have the same operating temperature range?
Yes. Both variants are specified over the industrial temperature range of -40°C to +85°C, as defined in the Analog Devices AD8170 datasheet. The packaging format does not affect the temperature grade.
Can I use AD8170ARZ-RL as a drop-in replacement for AD8170ARZ on an existing PCB?
Yes. Because both are the identical AD8170 die in the same 8-lead SOIC footprint with the same pinout and specifications, AD8170ARZ-RL is a drop-in replacement for AD8170ARZ on an existing PCB. Only the delivery format differs, so no layout or design change is required.
