The HT5010/1/2 family is a low-cost stereo digital to analog converter, including interpolation, multibit D/A conversion and output analog filtering in a 10-pin package.
The device family can accept multiple audio formats up to 24-bit word length.
The device family is based on an advanced multi-bit Δ-Σ modulator to convert data into two channel analog outputs with a linear analog low-pass filter. The multi-bit Δ-Σ modulator makes the device with very low sensitivity to clock jitter and very low out-of-band noise. It also includes auto speed mode detection using both sample rate and master clock ratio as a method of auto-selecting sampling rates between 2 kHz and 200 kHz.
The device family contains on-chip digital deemphasis, operates from a single +3.3 V power supply, and requires minimal support circuitry. These features are ideal for DVD players & recorders, digital televisions, home theater and set top box products, and automotive audio systems.
The device family is available in a 10-pin MSOP package.
