Frequently asked questions
What is the difference between AD627ARZ-RL and AD627ARZ?
Both parts are the same AD627 instrumentation amplifier in an 8-lead SOIC package (R-8 suffix). The difference is packaging format: AD627ARZ is supplied in standard tube/tray quantities, while AD627ARZ-RL is supplied on tape and reel for automated assembly. Electrical specifications are identical per the Analog Devices datasheet.
Are AD627ARZ-RL and AD627ARZ electrically identical?
Yes. Both share the same die, grade, and specification table in the Analog Devices AD627 datasheet. The "-RL" suffix denotes reel packaging only and does not change gain range, offset voltage, supply range, or bandwidth.
Can AD627ARZ-RL be used as a drop-in replacement for AD627ARZ?
Yes, provided the assembly process supports tape-and-reel feeding. The package footprint, pinout, and electrical performance are the same, so no PCB or circuit redesign is required.
What package do AD627ARZ-RL and AD627ARZ use?
Both are offered in an 8-lead SOIC package (R-8) with an operating temperature range of -40°C to +85°C, as specified in the Analog Devices AD627 datasheet.
What is the gain range of the AD627?
The AD627 is a micropower instrumentation amplifier with a gain range of 5 V/V to 1000 V/V set by a single external resistor, per the Analog Devices datasheet.
What supply voltage range does the AD627 support?
The AD627 operates from a single supply of 2.2 V to 36 V, or dual supplies of ±1.1 V to ±18 V, according to the Analog Devices datasheet.
Why would a designer choose the -RL reel version over the tube version?
The -RL tape-and-reel format is intended for high-volume automated pick-and-place assembly, reducing manual handling and feeder reloads. For low-volume or prototyping, the standard AD627ARZ tube format may be more convenient.
