Replacement verdict
Compatible functional replacement candidate
The AK4396VF and AK4393VM are both 24-bit multi-bit delta-sigma stereo DACs from Asahi Kasei Microdevices, sharing a common functional role in digital audio conversion. However, they differ in package footprint, supply voltage range, and dynamic performance, so the AK4396VF is a functional replacement candidate for the AK4393VM only after validating package compatibility, power supply requirements, and audio performance targets against the specific application.

Key electrical and mechanical differences between the two devices
| Parameter | AK4396VF | AK4393VM | Why it matters |
|---|---|---|---|
| Resolution (bits) | 24 | 24 | Both are 24-bit DACs, so bit depth is not a differentiator for substitutability. |
| Number of DAC channels | 2 (stereo) | 2 (stereo) | Both are stereo DACs; channel count must match the target audio path. |
| Dynamic range (DAC) | 120 dB | 108 dB | Higher dynamic range yields lower noise floor and better low-level detail; the AK4396VF is notably superior here. |
| THD+N | -100 dB | -94 dB | Lower distortion improves fidelity; the AK4396VF offers better linearity than the AK4393VM. |
| Supported sampling frequency | Up to 216 kHz | Up to 96 kHz | Higher sample-rate support enables high-resolution audio; the AK4396VF supports wider input rates. |
| Digital audio interface | I2S / 24-bit serial | I2S / 24-bit serial | Matching digital interface formats ensures drop-in compatibility with the host DSP or receiver. |
| Supply voltage (analog) | 5 V | 5 V | Same analog supply simplifies power-rail reuse when substituting parts. |
| Package | 28-pin VSOP | 28-pin SSOP | Package footprint and pinout must match for board-level interchangeability; differing package types may require layout changes. |
| Operating temperature range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings mean both suit the same environmental conditions. |

Frequently asked questions
What are the key differences between the AK4396VF and AK4393VM audio DACs?
The AK4396VF is a 24-bit 192 kHz advanced segment stereo DAC with 120 dB dynamic range and -100 dB THD+N, while the AK4393VM is a 24-bit 96 kHz stereo DAC with 108 dB dynamic range and -94 dB THD+N. The AK4396VF supports higher sample rates and offers improved dynamic range and distortion performance compared to the AK4393VM.
Do the AK4396VF and AK4393VM use the same package type?
No. The AK4396VF is supplied in a 28-pin VSOP package, while the AK4393VM is supplied in a 28-pin SSOP package. The package footprints and pin assignments differ, so they are not drop-in replacements for each other.
What sample rates do the AK4396VF and AK4393VM support?
The AK4396VF supports PCM sample rates from 8 kHz to 192 kHz. The AK4393VM supports PCM sample rates from 8 kHz to 96 kHz. Designs requiring 192 kHz operation must use the AK4396VF.
How do the dynamic range specifications compare between the AK4396VF and AK4393VM?
The AK4396VF achieves 120 dB dynamic range, whereas the AK4393VM achieves 108 dB dynamic range. The AK4396VF therefore provides approximately 12 dB better dynamic range, which can benefit high-resolution audio applications.
How do the THD+N specifications compare between the AK4396VF and AK4393VM?
The AK4396VF specifies -100 dB THD+N, while the AK4393VM specifies -94 dB THD+N. The AK4396VF offers lower distortion and noise, making it preferable for applications demanding higher audio fidelity.
Are the AK4396VF and AK4393VM pin-compatible?
No. Although both are 28-pin devices, the AK4396VF uses a VSOP package and the AK4393VM uses an SSOP package, and their pin assignments and package dimensions differ. A PCB redesign is required when substituting one for the other.
What digital audio interfaces do the AK4396VF and AK4393VM support?
Both devices support PCM digital audio input. The AK4396VF supports sample rates up to 192 kHz, while the AK4393VM supports sample rates up to 96 kHz. Designers should consult the respective AKM datasheets for the exact interface format and configuration options of each device.
Can the AK4393VM be replaced by the AK4396VF in an existing design?
Not as a direct drop-in replacement. The AK4396VF offers higher sample rate support and better dynamic range and THD+N, but it uses a different package (VSOP vs SSOP) with different pin assignments. Replacement requires PCB layout changes and verification of the digital interface and power supply requirements against the AK4396VF datasheet.
