TAS5086 is a six-channel PWM processor from TI. It supports 32-, 44.1-, 48-, 88.2-, 96-, 176.4-, 192 kHz sampling rates, has a dynamic range of ≥105-dB and THD of <0.06%. It supports multiple data formats and clock rates.
The TAS5086 PurePath Digital Audio PWM Processor provides six PWM audio output channels that can be mapped to any output pin and supports both single‑ended and bridge‑tied load configurations. It includes features such as integrated bass management, two programmable biquads, and a flexible serial audio interface supporting a wide range of sampling rates and data formats.
Key specifications include a master clock rate up to 50 MHz, volume control ranging from 48 dB to –100 dB, THD less than 0.06 %, and a dynamic range of 210 dB when paired with the TAS5186. The device operates from a single 3.3‑V supply and is packaged in a 38‑pin TSSOP.
