TAS5701

illustrate

The TAS5701 is a 20-watt high-efficiency, digitally driven audio power amplifier for stereo bridged speakers. The two input serial data supports up to 3 independent audio channels. The SDIN1 input is routed to the internal left and right outputs. This SDIN2 input is dedicated to SUB_PWM ± output.

TAS5701 is a slave to a clock, and the only device that receives from an external clock. The TAS5701 operates at 384 kHz switching speeds of 32-, 48-, 96-, and 192 kHz and 352.8 kHz switching frequencies of 44.1-, 88.2-, and 176.4 kHz. 8 × sampling combined with a fourth-order noise shaper provides a unit noise substrate from 20 Hz and an excellent dynamic range of 20 kHz.

characteristic

• Audio input/output
  • 8 - 20 WThe load is from an 18 V power supply
  • Wide PVDD range (0 V to 21 V).
  • Efficient Class D operation eliminates the need for a radiator
  • Two serial (3 audio channels) audio inputs
  • Supports sample rates from 32 kHz to 192 kHz (2 seconds per RJ/me)
  • Subwoofer with line-level PWM output
• Audio/pulse width modulation processing
  • BD (no filter) modulation supports bridging only loading
  • 4 levels of volume control (0 dB, 6 dB, 12 dB, 18 dB)
    - All channels share the same controls
  • Soft Silent (50% Duty Cycle)
  • DC Barrier Filter
  • Fixed at 97.7%, maximum modulation limit
  • ≥ 100 dB signal-to-noise ratio - THD + N = 1% in use, measured by 1 kHz maximum output,
    A-weighted noise, gain = 0 dB
  • 总谐波失真
• General characteristics
  • 5 - V tolerance input (see 5 V Fault Tolerance entered on the pin list for details)
  • Shutdown mode for low power consumption
  • Thermal and short-circuit protection
  • Auto-Detect: Automatically detects changes in sampling rate -
    No need for external microprocessor intervention
