Key electrical and mechanical differences between the two devices
| Parameter | AD5162BRMZ10 | AD5161BRM10 | Why it matters |
|---|---|---|---|
| Number of Positions | 256 | 256 | Both provide 256 wiper positions, so resolution is equivalent for digital adjustment. |
| End-to-End Resistance | 10 kΩ | 10 kΩ | Matching nominal resistance allows direct substitution in most divider or rheostat circuits. |
| Interface Type | SPI | I2C | Different digital interfaces require different host controller wiring and firmware, affecting drop-in compatibility. |
| Number of Channels | 2 | 1 | Channel count determines how many independent resistance settings are available in one package. |
| Package / Mounting Type | 10-TFSOP, 10-MSOP (Surface Mount) | 10-MSOP (Surface Mount) | Package footprint and mounting must match the PCB layout for physical interchangeability. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Compatible supply ranges allow operation from the same system rails without level shifting. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +85°C | Wider temperature rating supports use in harsher environments and industrial applications. |
| Wiper Resistance | 50 Ω typical | 50 Ω typical | Similar wiper resistance keeps insertion loss and loading effects comparable between parts. |
| Nonvolatile Memory | No | No | Neither retains the wiper setting after power loss, so both require reinitialization at startup. |

Frequently asked questions
What are the key differences between the AD5162BRMZ10 and AD5161BRM10?
The AD5162BRMZ10 is a dual-channel, 10 kΩ digital potentiometer with 256 positions and an SPI-compatible interface, supplied in a 10-lead MSOP package. The AD5161BRM10 is a single-channel, 10 kΩ digital potentiometer with 256 positions and an I²C-compatible interface, supplied in a 10-lead MSOP package. The primary differences are channel count (2 vs. 1) and control interface (SPI vs. I²C).
Are the AD5162BRMZ10 and AD5161BRM10 pin-compatible?
No. Although both devices are offered in a 10-lead MSOP package, their pin functions differ because the AD5162BRMZ10 provides two independent resistor channels while the AD5161BRM10 provides one channel. Pin assignments for the digital interface, address pins, and resistor terminals are not identical, so they cannot be treated as pin-compatible substitutes.
Can the AD5162BRMZ10 directly replace the AD5161BRM10 in an existing design?
No, not without design changes. The AD5162BRMZ10 uses an SPI-compatible interface and contains two potentiometer channels, whereas the AD5161BRM10 uses an I²C-compatible interface and contains one channel. The host controller firmware, PCB layout, and external connections must be revised to accommodate these differences.
Do both devices have the same end-to-end resistance and resolution?
Yes. Both the AD5162BRMZ10 and AD5161BRM10 are specified with a 10 kΩ nominal end-to-end resistance and 256-position resolution, providing 8-bit adjustment capability. The resistance tolerance and temperature coefficient should be verified against the respective manufacturer datasheets for the target application.
What supply voltage range do the AD5162BRMZ10 and AD5161BRM10 support?
Both devices operate from a single 2.7 V to 5.5 V supply, according to their manufacturer datasheets. This allows use in 3 V and 5 V mixed-signal systems. Always confirm the exact operating conditions and timing specifications in the official datasheet before finalizing a design.
Which device is better for systems that already use an I²C bus?
The AD5161BRM10 is the appropriate choice for systems with an existing I²C bus because it communicates via an I²C-compatible interface. The AD5162BRMZ10 requires an SPI-compatible bus, so it would need additional interface resources or a bus conversion if the host only supports I²C.
Which device is better when two independent resistance channels are required?
The AD5162BRMZ10 is the appropriate choice when two independently programmable resistance channels are needed, since it integrates two 10 kΩ, 256-position digital potentiometers in one package. The AD5161BRM10 provides only a single channel, so two devices would be required to achieve the same channel count.
Are the AD5162BRMZ10 and AD5161BRM10 available in the same package type?
Both devices are offered in a 10-lead MSOP package. However, because their pin functions and channel counts differ, the package similarity does not imply interchangeability. PCB land patterns may be similar, but the electrical connections and external circuitry must be designed for the specific device.
