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
- Notebooks
- Portable audio equipement
- Sound cards

A cool wooden model for self-assembly from the new UGEARS Trucks Collection.
Based on UGM-11 Truck, the Mechanical Tanker model has real TANKER with the unique opening mechanism which fits well for standard 0.33 L cans. Twist the knob on the tanker’s cap and unfold it in surprising way. This model is deliberately designed to have a raw, open look so even the casual observer could appreciate the marvels going on inside. UGears 70021
