Key electrical and mechanical differences between the two devices
| Parameter | AD8236ARMZ | AD8236ARMZ-RL | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures consistent design, documentation, and quality standards. |
| Amplifier Type | Instrumentation Amplifier | Instrumentation Amplifier | Defines the core function; both are instrumentation amplifiers suitable for precision signal conditioning. |
| Number of Channels | 1 | 1 | Channel count must match the circuit's signal path requirements. |
| Package / Case | 8-Lead MSOP (MSOP-8) | 8-Lead MSOP (MSOP-8) | Footprint compatibility is essential for drop-in substitution on an existing PCB. |
| Mounting Type | Surface Mount | Surface Mount | Assembly method must match the board's manufacturing process. |
| Supply Voltage Range | 1.8 V to 5.5 V (single supply) | 1.8 V to 5.5 V (single supply) | Operating voltage range must be compatible with the system power rails. |
| Supply Current (typical) | 50 µA | 50 µA | Quiescent current affects power budget, especially in battery-powered designs. |
| Input Offset Voltage (max) | ±250 µV | ±250 µV | Offset voltage directly impacts DC accuracy of the signal chain. |
| Gain Bandwidth Product | 23 kHz | 23 kHz | Bandwidth determines the maximum signal frequency the amplifier can handle at a given gain. |
| Packaging / Ordering Format | Tube / cut tape (individual units) | Tape & Reel (RL suffix) | Packaging differs for automated assembly; the -RL variant is supplied on reels for high-volume pick-and-place production, while the base part is typically tube or cut tape. |

Frequently asked questions
What is the difference between AD8236ARMZ and AD8236ARMZ-RL?
Both parts are the same AD8236 micropower instrumentation amplifier in an 8-lead MSOP package. The AD8236ARMZ is the standard tube or tray packaging option, while the AD8236ARMZ-RL is the tape-and-reel packaging option. The electrical specifications and die are identical; only the packaging and ordering quantity differ.
Are AD8236ARMZ and AD8236ARMZ-RL electrically and functionally interchangeable?
Yes. Both order codes refer to the same AD8236ARMZ silicon in the same 8-lead MSOP (RM-8) package, so they are electrically and functionally interchangeable. The suffix -RL only designates tape-and-reel packing for automated assembly.
What package do AD8236ARMZ and AD8236ARMZ-RL use?
Both parts are supplied in the 8-lead MSOP (Mini Small Outline Package), designated RM-8 by Analog Devices. The package is RoHS-compliant and specified for the extended industrial temperature range of -40°C to +125°C.
What are the key specifications of the AD8236?
The AD8236 is a micropower instrumentation amplifier with a typical supply current of 40 µA, a gain range of 5 to 1000 set by a single external resistor, a typical input offset voltage of 250 µV, a typical CMRR of 110 dB (G = 100), and a typical gain bandwidth of 23 kHz. It operates from a single supply of 1.8 V to 5.5 V (or dual supplies of ±0.9 V to ±2.5 V).
Which packaging option should be selected for production assembly?
AD8236ARMZ-RL (tape-and-reel) is intended for automated pick-and-place production lines, while AD8236ARMZ (tube/tray) is typically used for prototyping, low-volume runs, or manual assembly. Both contain the identical device.
Do AD8236ARMZ and AD8236ARMZ-RL share the same datasheet and qualification data?
Yes. Both order codes are covered by the same Analog Devices AD8236 datasheet and the same qualification and reliability data for the RM-8 package. No electrical, thermal, or reliability differences exist between the two order codes.
Can AD8236ARMZ and AD8236ARMZ-RL be mixed on the same PCB assembly?
Yes. Because both order codes are the same device in the same 8-lead MSOP package with identical pinout and specifications, they can be used interchangeably on the same PCB assembly without any design change.
