TS4657: single supply stereo digital audio line driver with 2.2 Vrms capless outputs


The TS4657 is a stereo DAC that integrates a high-performance audio line driver capable of generating a 2.2 Vrms output level from a single 3.0 to 5.5 V supply.
One single supply is sufficient for the digital and analog parts of the circuit, thus eliminating the need for external regulators. The TS4657 is a low-power consumption device. It features only 22 mW power dissipation at a 3.0 V power supply in full operation.
A multi-bit sigma delta DAC is used, operating at 256xFs with oversampling digital interpolation filters. The digital audio data can be 16-to 24-bit long and sample rates from 32 to 48 kHz are supported.
The output stage signal is ground-referenced by using an internal self-generated negative power supply, and as such external bulky output coupling capacitors are not necessary.

Key features

  • Single 3.0 to 5.5 V supply for DAC and line driver
  • Audio line output: 2.2 Vrms for all VCC range
  • 16- to 24-bit audio data format stereo DAC, 32 to 48 kHz sample rate
  • I2S, right- or left-justified compatible digital audio interface
  • 95 dB SNR A-weighted at 48 kHz, VCC =5 V
  • 7.4 mA current consumption at VCC = 3.0 V, full operation
  • Internal negative power supply to ensure ground-referenced, capless outputs
  • No external capacitor needed for the negative power supply generation
  • Integrated structure to suppress pop and click noise


Applications

  • Digital set-top-boxes
  • DVD players
  • Digital TVs
