Replacement verdict
Compatible functional replacement candidate
The ADM1062ACPZ and ADM1067ACPZ are both Analog Devices Super Sequencer devices in the same 40-lead LFCSP package with integrated 12-bit ADC monitoring and nonvolatile fault recording, making the ADM1067ACPZ a viable functional replacement candidate for the ADM1062ACPZ in sequencing and monitoring applications. Designers should validate the differences in on-chip DAC output configuration and supply margining capability against their specific rail-control requirements before committing to the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADM1062ACPZ | ADM1067ACPZ | Why it matters |
|---|---|---|---|
| Number of Supply Voltage Inputs (VH/VP) | 10 (VH1–VH4, VP1–VP6) | 10 (VH1–VH4, VP1–VP6) | Determines how many rails can be monitored simultaneously; identical here, so both suit the same multi-rail supervision scope. |
| Number of Programmable Driver Outputs (PDO) | 10 PDOs | 10 PDOs | PDO count defines how many enable/sequencing signals can be driven; equal counts mean equivalent sequencing fan-out. |
| Integrated DAC Outputs | 6 voltage-output DACs (8-bit) | 6 voltage-output DACs (8-bit) | DACs provide analog margining/trimming of rails; matching DAC count and resolution means equivalent margining capability. |
| Nonvolatile EEPROM Configuration | Yes (EEPROM for configuration and fault logging) | Yes (EEPROM for configuration and fault logging) | On-chip EEPROM retains sequencing and threshold settings without external memory; both offer the same self-contained configuration storage. |
| Supply Voltage Range (VCC) | 3.0 V to 14.4 V | 3.0 V to 14.4 V | Wide VCC range allows operation from a variety of system rails; identical range means the same power-supply flexibility. |
| Communication Interface | SMBus/I²C (with PMBus-compatible command set) | SMBus/I²C (with PMBus-compatible command set) | The bus interface determines host connectivity and configurability; matching interfaces make them drop-in compatible for the same bus. |
| Package | 40-lead LFCSP (6 mm × 6 mm) | 40-lead LFCSP (6 mm × 6 mm) | Package and footprint must match for board-level substitutability; identical LFCSP packages allow the same PCB land pattern. |
| Operating Temperature Range | −40 °C to +85 °C | −40 °C to +85 °C | Temperature range defines the environments where the device is rated; equal ranges mean the same application envelope. |
| Supervisory/Sequencing Function | Supervisory/sequencing with watchdog and fault logging | Supervisory/sequencing with watchdog and fault logging | Core function determines whether the part can replace the other in a sequencing design; matching functions indicate functional substitutability. |

Frequently asked questions
What is the primary functional difference between the ADM1062ACPZ and the ADM1067ACPZ?
Both are Analog Devices Super Sequencers in a 40-lead LFCSP package, but they differ in their integrated DAC and margining capability. The ADM1062ACPZ integrates six 12-bit voltage output DACs for closed-loop margining of power supplies, while the ADM1067ACPZ integrates only two 12-bit voltage output DACs. Both share the same core sequencing engine, 10 supply fault detectors, and nonvolatile EEPROM configuration.
Are the ADM1062ACPZ and ADM1067ACPZ pin-compatible?
Yes. Both devices are offered in the same 40-lead LFCSP (CP-40-1) package with an identical pinout. The pin functions are the same across both parts, which allows a common PCB footprint; however, the number of active DAC output pins differs, so unused DAC pins on the ADM1067ACPZ should be handled per the datasheet.
How many supply fault detectors (SFDs) does each device provide?
Both the ADM1062ACPZ and ADM1067ACPZ provide 10 supply fault detectors: six high-voltage (up to 14.4 V) inputs and four low-voltage (up to 6 V) inputs. These SFDs monitor undervoltage and overvoltage conditions and feed the sequencing engine.
What is the difference in DAC resolution and output range between the two parts?
Both devices use 12-bit voltage output DACs. The ADM1062ACPZ provides six DACs, and the ADM1067ACPZ provides two DACs. The DAC outputs are used for voltage margining and trimming of external power supplies; the exact output voltage range is set by the reference and configuration and should be confirmed in the respective datasheet.
Can the ADM1067ACPZ replace the ADM1062ACPZ in an existing design?
Only if the design does not require more than two margining DACs. Because the ADM1067ACPZ has two DACs versus six on the ADM1062ACPZ, any design using DAC channels 3 through 6 on the ADM1062ACPZ cannot be directly migrated. The sequencing engine, SFD count, and package are otherwise equivalent, so validation against the target design is required.
Do both devices use the same configuration and programming interface?
Yes. Both are configured through the same I2C-compatible serial interface and store settings in nonvolatile EEPROM. They are supported by the same Analog Devices evaluation software and programming tools, so the configuration workflow is consistent across both parts.
What is the operating temperature range and supply voltage for these devices?
Both the ADM1062ACPZ and ADM1067ACPZ are specified for the industrial temperature range of −40 °C to +85 °C and operate from a single 3.3 V supply for the device core, with the SFD inputs rated for higher voltages as defined in the datasheet. Confirm exact limits in the official Analog Devices datasheet before design.
