AX5689

4-Channel, Digital-Input Class-D Audio Controller

Datasheet

Description

The AX5689 is a 4-channel bridge-tied load (BTL) or 2-channel parallel bridge-tied load (PBTL) audio controller IC with digital inputs, integrated low-latency analog-to-digital converters (ADCs), and CMOS-level pulse-width modulation (PWM) outputs. It enables high-order digital control loops with post-filter feedback for low power consumption and exceptional audio performance. It is available in a QFN-64 (9mmx9mm) package.

Configurations:

4x BTL
2x PBTL

Features & Benefits

8 Flexible, Differential Low-Latency Analog-to-Digital Converters (ADCs)
8 Configurable, Digital Control Loop Filter Slices
8 CMOS-Level Pulse-Width Modluation (PWM) Outputs
Up to 4x Bridge-Tied Load (BTL) Channels, 2x 4-Phase Parallel Bridge-Tied Load (PBTL) Channel, or Combination Thereof
Feedback Is Taken after the Output Filter to Reduce Distortion
Multiple ADCs Can Be Placed in Parallel for Higher Performance
Configurable Interconnections between Slices and ADCs for Versatility and Multiple Input, Multiple Output (MIMO) Control
I²C and SPI Control Interface with Selectable Address for Multi-Chip Systems

Applications:

Active Loudspeakers (Party Boxes, Monitor Speakers)
Streaming Audio Amplifier Solutions
Soundbars and Subwoofers
Professional Audio Solutions
Thermally Sensitive Audio Solutions
