Replacement verdict
Compatible functional replacement candidate
The ADM1062ACPZ and ADM1069ACPZ are both Analog Devices Super Sequencers in the same 40-lead LFCSP package with a common supply and supervisory architecture, making the ADM1069ACPZ a viable functional replacement candidate for the ADM1062ACPZ in sequencing and monitoring applications. However, the two devices differ in on-chip DAC resolution and EEPROM capacity, so the replacement should be validated against the specific margining and configuration-storage requirements of the target design before adoption.

Key electrical and mechanical differences between the two devices
| Parameter | ADM1062ACPZ | ADM1069ACPZ | Why it matters |
|---|---|---|---|
| Number of Supply Voltage Inputs (VH/VP) | 10 (VH1–VH4, VP1–VP6) | 8 (VH1–VH4, VP1–VP4) | Determines how many rails can be monitored simultaneously; a board needing more than 8 monitored rails cannot directly substitute the 8-input device. |
| Number of Programmable Driver Outputs (PDO) | 10 PDOs | 8 PDOs | PDO count limits how many enable/sequencing signals can be generated; fewer outputs may require external logic to replicate the sequencing scheme. |
| Number of General-Purpose Inputs (GPIN) | 6 GPINs | 4 GPINs | GPINs are used for external control/handshake signals; a design relying on more than 4 GPINs cannot be directly ported to the smaller device. |
| On-Chip DAC Outputs | 2 voltage DAC outputs (VOUT1, VOUT2) | None | The ADM1062 can generate analog margining/trim voltages directly; the ADM1069 lacks DACs, so any margining function must be implemented externally. |
| Supply Voltage Range (VCC) | 3.0 V to 14.4 V | 3.0 V to 14.4 V | Both devices operate from the same wide supply range, so power-rail compatibility is maintained when substituting. |
| Nonvolatile EEPROM Configuration Storage | Yes (on-chip EEPROM) | Yes (on-chip EEPROM) | Both retain sequencing and threshold settings without power, allowing autonomous operation after configuration. |
| Package | 40-lead LFCSP (6 mm × 6 mm) | 40-lead LFCSP (6 mm × 6 mm) | Identical package and footprint simplifies board-level substitution without layout changes. |
| Operating Temperature Range | −40 °C to +85 °C | −40 °C to +85 °C | Matching industrial temperature ratings ensure equivalent environmental capability in the target application. |
| Communication Interface | SMBus/I²C (2-wire) | SMBus/I²C (2-wire) | Same serial interface allows the same host firmware and bus topology to configure and monitor either device. |

Frequently asked questions
What are the ADM1062ACPZ and ADM1069ACPZ?
The ADM1062ACPZ and ADM1069ACPZ are both Analog Devices Super Sequencers (programmable power supply sequencers and supervisors) in a 40-lead LFCSP (CP-40-1) package. They integrate a programmable state machine, EEPROM, and multiple voltage supervisors for sequencing and monitoring power rails in complex systems.
What is the key difference between the ADM1062ACPZ and ADM1069ACPZ?
The primary difference is the number of programmable supply detector inputs and the associated feature set. The ADM1062 provides 10 programmable supply detector inputs (VH/VP/VX pins), while the ADM1069 provides 12 programmable supply detector inputs. The ADM1069 also adds a dedicated watchdog timer input and additional general-purpose inputs compared with the ADM1062. Both share the same 40-lead LFCSP footprint and I2C/SMBus interface.
Are the ADM1062ACPZ and ADM1069ACPZ pin-compatible?
Both devices use the same 40-lead LFCSP (CP-40-1) package with identical package dimensions and lead pitch, but they are not functionally pin-for-pin interchangeable because several pins are assigned different functions (for example, additional supply detector inputs and watchdog-related pins on the ADM1069). A direct drop-in substitution requires verifying each pin function against both datasheets.
What supply voltage range do these devices support?
Both the ADM1062 and ADM1069 operate from a single VCC supply of 3.0 V to 3.6 V (3.3 V nominal). The programmable supply detector inputs (VH, VP, VX) support high-voltage monitoring up to 14.4 V on the VH pins, allowing direct supervision of 12 V, 5 V, 3.3 V, and other rails without external resistor dividers on those inputs.
What communication interface do the ADM1062ACPZ and ADM1069ACPZ use?
Both devices provide an I2C-compatible/SMBus two-wire serial interface for configuration, margining, and status readback. The interface supports standard-mode and fast-mode operation and allows the devices to be programmed and monitored by a host controller or in-system via the SMBus.
How is configuration stored and is it retained without power?
Both the ADM1062 and ADM1069 store their sequencing and supervision configuration in on-chip EEPROM, which is non-volatile and retains settings without power applied. Configuration can be written via the I2C/SMBus interface and is loaded automatically at power-up.
Can the ADM1062ACPZ be replaced by the ADM1069ACPZ in an existing design?
Not as a direct drop-in replacement without design review. Although both share the 40-lead LFCSP package and 3.3 V supply and I2C interface, the ADM1069 offers additional supply detector inputs and watchdog functionality with different pin assignments. The schematic, pin assignments, and EEPROM configuration must be revalidated against the ADM1069 datasheet before substitution.
What are typical applications for these Super Sequencers?
Both devices are used for power-supply sequencing and supervision in telecommunications, networking, server, storage, and industrial systems, where multiple rails must be brought up and shut down in a controlled order and monitored for fault conditions. The ADM1069's additional detector inputs suit systems with a higher number of rails to supervise.
