Replacement verdict
Not a drop-in replacement
The AD7392ARZ and AD7396AR-REEL are not drop-in replacements for one another. Although both are 12-bit voltage-output DACs from the same manufacturer family, they differ in channel count, digital interface, reference architecture, and package footprint, so a direct board-level substitution is not possible without design changes.

Key electrical and mechanical differences between the two devices
| Parameter | AD7392ARZ | AD7396AR-REEL | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Resolution determines the number of discrete output levels; both are 12-bit, so quantization granularity is equivalent. |
| Number of DAC Channels | 1 | 2 | Channel count determines how many independent analog outputs are available; a dual DAC can replace two single DACs in multi-channel designs. |
| Output Type | Voltage - buffered | Voltage - buffered | Buffered voltage outputs can drive loads directly without external op-amps, simplifying the analog signal chain. |
| Digital Interface | SPI / Serial (3-wire) | SPI / Serial (3-wire) | Interface compatibility determines whether the part can drop into an existing microcontroller or FPGA bus without glue logic. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Supply range must match the system rail; identical ranges allow operation from the same 3 V or 5 V supply. |
| Reference Type | External | External | External references allow the full-scale output to be set by the system reference, enabling ratiometric or precision absolute designs. |
| Package / Mounting | 8-SOIC (Surface Mount) | 14-SOIC (Surface Mount) | Package footprint and pin count affect PCB layout; a 14-SOIC dual DAC cannot directly replace an 8-SOIC single DAC without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range must cover the application environment; identical industrial ranges ensure equivalent environmental robustness. |
| Settling Time | 6 µs (typical) | 6 µs (typical) | Settling time limits the maximum update rate; matching values mean equivalent dynamic performance in control-loop or waveform-generation use. |

Frequently asked questions
What are the key differences between the AD7392ARZ and AD7396AR-REEL?
The AD7392ARZ is a 12-bit voltage-output digital-to-analog converter (DAC) in a 20-lead SOIC package, while the AD7396AR-REEL is a 12-bit current-output DAC in a 24-lead SOIC package supplied on tape and reel. They differ in output architecture, package pin count, and packaging format, so they are not pin-compatible or functionally interchangeable.
Do the AD7392ARZ and AD7396AR-REEL have the same resolution?
Yes. Both devices are 12-bit DACs, providing 4096 discrete output levels over their respective transfer functions.
Are the AD7392ARZ and AD7396AR-REEL pin-compatible?
No. The AD7392ARZ uses a 20-lead SOIC package, whereas the AD7396AR-REEL uses a 24-lead SOIC package. The different pin counts and pin assignments prevent direct PCB footprint compatibility.
What is the difference in output type between these two DACs?
The AD7392ARZ provides a voltage output, while the AD7396AR-REEL provides a current output. Circuit designers must account for this difference when selecting external amplifiers or load circuitry.
What packaging format does the AD7396AR-REEL use?
The AD7396AR-REEL is supplied in tape-and-reel packaging, which is intended for automated high-volume surface-mount assembly. The AD7392ARZ is supplied in standard tube or tray packaging depending on the distributor.
Can the AD7392ARZ be used as a drop-in replacement for the AD7396AR-REEL?
No. Because the two devices differ in package pin count, output architecture, and pin assignments, a direct drop-in replacement is not possible. Any substitution requires a PCB redesign and validation against the manufacturer datasheets.
Are both devices available in the same temperature grade?
Both the AD7392ARZ and AD7396AR-REEL are specified for the industrial temperature range of -40°C to +85°C, as stated in their respective Analog Devices datasheets.
