Key electrical and mechanical differences between the two devices
| Parameter | AK4396VF | AK4393VF | Why it matters |
|---|---|---|---|
| Resolution (bits) | 24 | 24 | Both are 24-bit DACs, so bit depth is not a differentiator for substitutability. |
| Dynamic Range (dB) | 120 | 108 | Higher dynamic range yields lower noise floor and better low-level detail; the AK4396 offers a significant advantage. |
| THD+N (dB) | -100 | -94 | Lower distortion improves fidelity; the AK4396 is cleaner, which matters for high-quality audio reproduction. |
| Sampling Rate (max, kHz) | 216 | 192 | Higher maximum sample rate supports higher-resolution audio formats and future-proofs the design. |
| Digital Interface | I2S / Left-Justified / Right-Justified / TDM | I2S / Left-Justified / Right-Justified | Interface compatibility determines whether the DAC can drop into an existing digital audio path; TDM support in the AK4396 adds flexibility. |
| Supply Voltage (V) | 3.0 to 3.6 (digital), 4.75 to 5.25 (analog) | 3.0 to 3.6 (digital), 4.75 to 5.25 (analog) | Matching supply rails means the same power design can be reused, simplifying substitution. |
| Package | 28-pin VSOP | 28-pin VSOP | Identical package and pin count allow direct PCB footprint compatibility. |
| Operating Temperature Range (°C) | -40 to +85 | -40 to +85 | Same temperature range ensures equivalent environmental robustness in the target application. |
| Power Consumption (mW, typ) | ~120 | ~100 | Lower power draw benefits portable and thermally constrained designs; the AK4393 is slightly more efficient. |

Frequently asked questions
What are the key differences between the AK4396VF and AK4393VF 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 AK4393VF 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 lower distortion compared to the AK4393VF.
Are the AK4396VF and AK4393VF pin-compatible?
Both devices are offered in a 28-pin VSOP package, but pin compatibility must be confirmed against the respective AKM datasheets, as pin functions and control interfaces may differ between the two parts. Designers should verify the pinout and control register maps before considering a direct replacement.
What sample rates do the AK4396VF and AK4393VF support?
The AK4396VF supports PCM sample rates from 32 kHz to 192 kHz, while the AK4393VF supports PCM sample rates from 32 kHz to 96 kHz. The AK4396VF is therefore suitable for higher-resolution audio applications requiring up to 192 kHz operation.
What are the dynamic range specifications of the AK4396VF and AK4393VF?
The AK4396VF achieves a dynamic range of 120 dB, whereas the AK4393VF achieves 108 dB. The higher dynamic range of the AK4396VF makes it preferable for applications demanding greater signal-to-noise performance.
What THD+N performance do the AK4396VF and AK4393VF offer?
The AK4396VF specifies THD+N of -100 dB, while the AK4393VF specifies THD+N of -94 dB. The AK4396VF provides lower distortion and noise, which is beneficial for high-fidelity audio designs.
Do both the AK4396VF and AK4393VF support digital audio interfaces such as I2S?
Both devices support standard digital audio interfaces including I2S and left-justified formats, as documented in their respective AKM datasheets. Designers should confirm the specific interface mode and clock requirements for each part in the manufacturer documentation.
What are the typical applications for the AK4396VF versus the AK4393VF?
The AK4396VF is typically used in high-resolution audio equipment such as AV receivers, professional audio gear, and high-end DACs requiring up to 192 kHz support. The AK4393VF is suited for consumer audio products, set-top boxes, and other applications where 96 kHz support and 108 dB dynamic range are sufficient.
