CS4226-KQ

The CS4226-KQ belongs to CS4226, which is a single-chip codec providing stereo analog-to-digital and six digital-to-analog converters using delta-sigma conversion techniques. This +5 V device also contains volume control independently selectable for each of the six D/A channels. An S/PDIF receiver is included as a digital input channel. Applications include Dolby Pro-logic, THX, DTS and Dolby Digital AC-3 home theater systems, DSP based car audio systems, and other multi-channel applications. The CS4226 is packaged in a 44-pin plastic TQFP.

The features of CS4226 can be summarized as (1)stereo 20-bit A/D converters; (2)six 20-bit D/A converters; (3)S/PDIF receiver: AC-3 & MPEG auto-detect capability; (4)108 dB DAC signal-to-noise ratio (EIAJ); (5)mono 20-bit A/D converter; (6)programmable input gain & output attenuation; (7)on-chip anti-aliasing and output smoothing filters; (8)de-emphasis for 32 kHz, 44.1 kHz, 48 kHz.

The absolute maximum ratings of CS4226 are (1)power supplies digital(VD+)/Analog(VA+): all are -03 to 60 V; (2)input current (Note 16:Notes: Any pin except supplies transient currents of up to ±100 mA on the analog input pins will not cause SCR latch-up): ±10 mA(max); (3)analog input voltage (Note 17: The maximum over or under voltage is limited by the input current): -07 to (VA+)+07V; (4)digital input voltage (Note 17): -07 to (VD+)+07 V; (5)ambient temperature (power applied): -55 to +125 °C; (6)storage temperature: -65 yo +150 °C.(Warning: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes.)
