AK7738VQ FAQs

1.Q: What is the resolution of the AK7738VQ’s ADC and DAC?

A: The ADC has 24-bit resolution (single channel), while the dual DACs support 32-bit resolution (2 channels each).

2.Q: What interfaces does the AK7738VQ support?

A: It includes 1x SPI and 1x I2C for control, but no I2S, USB, CAN, or Ethernet. Audio data is processed internally via its ADC/DAC paths.

3.Q: What is the package type of the AK7738VQ?

A: It comes in a 64-pin LQFP (Low-profile Quad Flat Package) with dimensions 10x10x1.6mm (max height), suitable for surface-mount PCB designs.

4.Q: Does the AK7738VQ support automotive use?

A: No. The "Automotive" field is marked "Unknown," and PPAP status is unconfirmed. It’s primarily for consumer electronics (ECCN: EAR99).

5.Q: What applications is the AK7738VQ designed for?

A: It’s optimized for portable/wearable devices like wireless earbuds, smartwatches, and Bluetooth audio modules requiring high-resolution audio processing.

6.Q: What are the recommended operating conditions for the AK7738VQ?

A: The chip operates at 3.3V (typical), with a range of 1.7V–3.6V. Temperature range is -40°C to +85°C, and the input clock speed is up to 48MHz.

7.Q: What is the pinout configuration of the AK7738VQ?

A: The AK7738VQ has 64 pins in an LQFP package (10x10mm, gull-wing leads). Pin functions include power supply, I2C/SPI control, audio input/output, and clock signals. Refer to the datasheet for the detailed pinout diagram.

8.Q: What are the key features of the AK7738VQ?

A: The AK7738VQ features a 24-bit ADC, dual 32-bit DACs, floating-point arithmetic, 36KB RAM, and supports I2C/SPI interfaces. It operates at 1.7V–3.6V with a 48MHz clock, targeting portable/wearable devices.
