(1) Stresses beyond those listed under "absolute ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operation conditions" are not implied. Exposure to absolute-maximum conditions for extended periods may affect device reliability.
(2) 5-V tolerant inputs are RESET, PDN, MUTE, SCLK, LRCLK, MCLK, SDA, and SCL.
DescriptionThe TAS5086 is a six channel digital pulse width modulator (PWM) that provides both advanced per- formance and a high level of system integration.
TAS5086 is designed to interface seamlessly with most audio digital signal processors and MPEG decoders accepting a wide range of input data and clock formats.
The TAS5086 drives six channels of speakers in either single-ended or bridge tied load configurations that accept a 1N+1 interface format. TAS5086 also supports 2N+1 power stages with the use of some external logic (e.g. TAS5112). Stereo line out in I2S format is available with either a pass-through signal (SDIN4) or an internal down mix.
TAS5086 uses AD modulation operating at a 384-kHz switching rate for 32-, 44.1-, 48-, 88.2-, 96-, 176.4-, and 192-kHz data. The 8 x over sampling combined with the 4th order noise shaper provides a broad flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.
TAS5086 is clock slave only device. TAS5086 re- ceives MCLK, SCLK and LRCLK from other system components. TAS5086 accepts master clock rates of 128, 192, 256, 384, and 512 Fs. TAS5086 accepts a 64 Fs master clock for 176.4-kHz and 192-kHz data.
