Frequently asked questions
What are the key differences between the AD620BRZ and AD620BR-REEL7?
The AD620BRZ is supplied in a 8-lead SOIC tube packaging, while the AD620BR-REEL7 is the same AD620BR grade device supplied in a 7-inch tape and reel for automated assembly. Both share the same die, specifications, and 8-lead SOIC package; the difference is packaging and shipping format.
Are the AD620BRZ and AD620BR-REEL7 electrically and functionally identical?
Yes. Both are AD620 instrumentation amplifiers in the B grade (SOIC-8), with the same gain equation (G = 49.4 kΩ/RG + 1), supply range of ±2.3 V to ±18 V, and specified performance. The only distinction is the delivery format: tube (AD620BRZ) versus tape and reel (AD620BR-REEL7).
Can the AD620BR-REEL7 be used as a drop-in replacement for the AD620BRZ?
Yes, from an electrical and footprint standpoint they are interchangeable because both are the same AD620BR die in an 8-lead SOIC package. The choice depends on assembly method: tape and reel for pick-and-place production, tubes for manual or low-volume assembly.
What is the difference between the "Z" suffix in AD620BRZ and the "REEL7" suffix in AD620BR-REEL7?
The "Z" suffix denotes RoHS-compliant packaging (lead-free) for the AD620BRZ. The "REEL7" suffix denotes a 7-inch tape-and-reel shipping format for the AD620BR-REEL7. Both are RoHS-compliant AD620BR-grade devices; the suffixes describe compliance and packaging, not performance grade.
What are the package and pinout specifications shared by both parts?
Both are offered in an 8-lead SOIC package with the standard AD620 pinout: pin 1 and pin 8 for gain resistor RG, pins 2 and 3 for inverting and non-inverting inputs, pin 4 for -VS, pin 5 for REF, pin 6 for OUTPUT, and pin 7 for +VS. The package and pinout are identical between the two orderable part numbers.
Which part should be selected for high-volume automated PCB assembly?
The AD620BR-REEL7 is the appropriate choice for high-volume automated assembly because it is supplied on 7-inch tape and reel, which is compatible with standard pick-and-place equipment. The AD620BRZ in tubes is better suited to low-volume or manual assembly.
Do both parts share the same operating temperature range and supply specifications?
Yes. Both the AD620BRZ and AD620BR-REEL7 are specified over the industrial temperature range of -40°C to +85°C and operate from dual supplies of ±2.3 V to ±18 V, with the same quiescent current and gain-bandwidth characteristics as the AD620BR grade.
