Replacement verdict
Compatible functional replacement candidate
The AD5664ARMZ and AD5662ARM-1 are both 16-bit nanoDAC single-supply voltage-output DACs from Analog Devices in the same 10-lead MSOP package, sharing a compatible SPI interface and similar reference architecture. However, the AD5664ARMZ integrates four independent DAC channels while the AD5662ARM-1 provides only a single channel, and their digital interface word lengths and internal reference options differ. The AD5662ARM-1 can serve as a functional substitute only when a single-channel DAC is acceptable and the system can accommodate the different command structure; otherwise the AD5664ARMZ remains the appropriate choice for multi-channel requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD5664ARMZ | AD5662ARM-1 | Why it matters |
|---|---|---|---|
| Number of DAC Channels | 4 | 1 | Determines how many independent analog outputs are available; a quad-channel device cannot be substituted by a single-channel device without redesigning the output stage. |
| Resolution | 16 bits | 16 bits | Both provide 16-bit resolution, so the achievable output granularity and accuracy class are equivalent. |
| Interface Type | SPI | I2C | The digital communication protocol must match the host controller; SPI and I2C are not directly interchangeable without firmware and pin changes. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Both operate over the same supply range, allowing use in similar low-voltage systems. |
| Reference Type | External | External | Both require an external reference, so the reference circuitry and accuracy budget remain comparable. |
| Package | 10-Lead MSOP | 8-Lead MSOP | Different pin counts and footprints affect PCB layout and may prevent a direct drop-in replacement. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +105°C | Both support the same industrial temperature range, so environmental suitability is equivalent. |
| Output Type | Voltage, buffered | Voltage, buffered | Both provide buffered voltage outputs, so the analog output stage behaves similarly in system design. |
| INL (Integral Nonlinearity) | ±16 LSB max | ±16 LSB max | Matching INL specifications indicate comparable linearity performance for precision applications. |

Frequently asked questions
What are the key differences between the AD5664ARMZ and the AD5662ARM-1?
The AD5664ARMZ is a quad-channel, 16-bit nanoDAC with a serial interface and an internal 2.5 V reference, while the AD5662ARM-1 is a single-channel, 16-bit nanoDAC with a serial interface and an internal 2.5 V reference. The AD5664ARMZ provides four independent DAC outputs in a 10-lead MSOP, whereas the AD5662ARM-1 provides one DAC output in an 8-lead MSOP.
Are the AD5664ARMZ and AD5662ARM-1 pin-compatible?
No. The AD5664ARMZ is supplied in a 10-lead MSOP package, while the AD5662ARM-1 is supplied in an 8-lead MSOP package. They have different pin counts and pin functions, so they are not pin-compatible.
Can the AD5662ARM-1 be used as a direct substitute for one channel of the AD5664ARMZ?
No. Although both are 16-bit nanoDACs with internal 2.5 V references and serial interfaces, they differ in channel count, package, and register architecture. A direct substitution requires validation against the specific design requirements and manufacturer datasheets.
What is the resolution and channel count of each device?
The AD5664ARMZ has 16-bit resolution and four DAC channels. The AD5662ARM-1 has 16-bit resolution and one DAC channel.
Do both devices include an internal reference?
Yes. Both the AD5664ARMZ and the AD5662ARM-1 include an internal 2.5 V reference, as specified in their respective manufacturer datasheets.
What serial interface do these DACs use?
Both the AD5664ARMZ and the AD5662ARM-1 use a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interface standards, as documented in their manufacturer datasheets.
What are the package options for the AD5664ARMZ and AD5662ARM-1?
The AD5664ARMZ is available in a 10-lead MSOP package. The AD5662ARM-1 is available in an 8-lead MSOP package.
Which device is better suited for multi-channel applications?
The AD5664ARMZ is better suited for multi-channel applications because it integrates four independent 16-bit DAC channels in a single 10-lead MSOP package, reducing board space and component count compared to using four separate single-channel DACs such as the AD5662ARM-1.
