digital converters (ADCs) that can be configured for 16-bit or 24-bit operation. Each ADC has a dedicated 1x to 128x low-noise programmable gain amplifier (PGA) driven by a 12-channel input multiplexer that can be configured for 12-channel single-ended or 6-channel differential operation. T e MAX32675C is particularly well-


Figure 4: The MAX32655 microcontroller’s integrated functionality enables designs with a minimal footprint and bill of materials, requiring few additional devices beyond a codec, a power management device and an interface device such as the DS2488 1-wire to implement a complete TWS earbud and charging cradle solution.
