Replacement verdict
Compatible functional replacement candidate
The AD5320BRMZ and AD5322BRMZ share the same 12-bit DAC resolution, 2.7 V to 5.5 V supply range, and MSOP-8 footprint, making them strong functional replacement candidates. However, the AD5320BRMZ is a single-channel voltage-output DAC, while the AD5322BRMZ is a dual-channel voltage-output DAC, so the channel count difference must be validated against the target application requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD5320BRMZ | AD5322BRMZ | Why it matters |
|---|---|---|---|
| Number of DAC Channels | 1 | 2 | Determines how many independent analog outputs are available; a single-channel device cannot directly replace a dual-channel device in multi-output designs. |
| Resolution | 12 bits | 12 bits | Both provide 12-bit resolution, so output granularity and accuracy class are equivalent for precision setpoint applications. |
| Interface Type | SPI-compatible (3-wire) | SPI-compatible (3-wire) | Both use a serial SPI interface, allowing similar microcontroller or DSP connectivity and firmware protocol handling. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Identical supply range means both can operate from common 3 V or 5 V rails without level shifting or regulator changes. |
| Output Voltage Range | 0 V to VREF | 0 V to VREF | Both provide rail-to-rail referenced output span, so the analog output scaling behavior is the same when using the same reference. |
| Reference Input | External reference | External reference | Both require an external reference, so system accuracy and output range depend on the same external reference design. |
| Package | 8-Lead MSOP | 10-Lead MSOP | Different package pin counts and footprints affect PCB layout, assembly, and whether a direct drop-in replacement is possible. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +105°C | Identical temperature ratings mean both are suitable for the same industrial and extended-temperature environments. |
| Power-Down Capability | Yes | Yes | Both support power-down modes, which is important for low-power system designs and energy-sensitive applications. |

Frequently asked questions
What are the key differences between the AD5320BRMZ and AD5322BRMZ?
The AD5320BRMZ is a single-channel, 12-bit voltage-output DAC in a 10-lead MSOP package, while the AD5322BRMZ is a dual-channel, 12-bit voltage-output DAC in a 10-lead MSOP package. Both share the same 12-bit resolution, 2.7 V to 5.5 V supply range, and SPI-compatible serial interface, but the AD5322BRMZ provides two independent DAC outputs in the same package footprint.
Are the AD5320BRMZ and AD5322BRMZ pin-compatible?
No. Although both devices are offered in a 10-lead MSOP package, their pin functions differ. The AD5320BRMZ uses the 10-lead MSOP for a single DAC output, while the AD5322BRMZ uses the same package to route two DAC outputs and associated reference and control pins. Designers must consult the respective datasheets before considering any layout reuse.
Do the AD5320BRMZ and AD5322BRMZ have the same resolution and accuracy specifications?
Both devices are 12-bit DACs. However, accuracy specifications such as INL, DNL, offset error, and gain error are specified separately in each datasheet and may differ. The AD5320BRMZ and AD5322BRMZ should each be evaluated against their own datasheet limits rather than assumed identical.
Can the AD5320BRMZ and AD5322BRMZ operate from the same supply voltage?
Yes. Both the AD5320BRMZ and AD5322BRMZ are specified for operation from a single supply of 2.7 V to 5.5 V, making them suitable for low-voltage, mixed-signal designs in that range.
What serial interface do the AD5320BRMZ and AD5322BRMZ use?
Both devices use an SPI-compatible, 3-wire serial interface. The AD5320BRMZ and AD5322BRMZ can be clocked at rates specified in their respective datasheets, and both support daisy-chain or multiple-device configurations depending on the system architecture.
Does the AD5322BRMZ consume more power than the AD5320BRMZ?
Because the AD5322BRMZ contains two DAC channels and the AD5320BRMZ contains one, power consumption differs between the two. Exact supply current and power-down current figures are specified separately in each datasheet and should be verified for the target operating conditions.
Can the AD5320BRMZ be used as a drop-in replacement for the AD5322BRMZ?
No. The AD5320BRMZ is a single-channel DAC and the AD5322BRMZ is a dual-channel DAC. They are not drop-in replacements for each other because the channel count, pin functions, and register map differ. Any substitution requires a full review of the datasheets and the target design.
Are the AD5320BRMZ and AD5322BRMZ available in the same package type?
Yes. Both the AD5320BRMZ and AD5322BRMZ are offered in a 10-lead MSOP package. However, identical package type does not imply identical pinout or functional equivalence, so the datasheets must be consulted for pin assignments and thermal considerations.
