CS4228A-KSZ

The CS4228A-KSZ belongs to CS4228A, whose codec provides two analog-to-digital and six digital-to-analog delta-sigma converters, along with volume controls, in a compact 28-pin SSOP device. Combined with an IEC958 (SPDIF) receiver (like the CS8414) and surround sound decoder (such as one of the CS492x or CS493xx families), it is ideal for use in DVD player, A/V receiver and car audio systems sup- porting multiple standards such as Dolby Digital AC-3, AAC, DTS, Dolby ProLogic, THX, and MPEG. A flexible serial audio interface allows operation in Left Justified, Right Justified, IZS, or One Line Data modes.
 
The features of CS4228A can be summarized as (1)six 24-bit D/A converters:100 dB dynamic range; -90 dB THD+N ; (2)Two 24-bit ND converters: 97 dB dynamic range; -95 dB THD+N ; (3)sample rates up to 100 kHz ; (4)pop-free digital output volume controls: 90.5 dB range, 0.5 dB resolution (182 levels); variable smooth ramp rate, 0.125 dB steps ; (5)mute control pin for off-chip muting circuits ; (6)on-chip anti-alias and output filters ; (7)de-emphasis tilters for 32, 44.1 and 48 kHz.
 
The maximum absolute ratings of CS4228A are (AGND, DGND = 0V, all voltages with respect to 0V) of CS4228A are(1)power supply, VA/VD/VL:-0.3 to 6.0V(analog)/-0.3 to 6.0V(digital)/-0.3 to 6.0(interface); (2)input current(Note 1: 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 2: The maximum over/under voltage is limited by the input current. ): -0.7 to VA+0.7 V; (4)digital input voltage: -0.7 to VL+ 2.5V(input pins)/-0.7 to VL+ 0.7V(bidiraction pins); (5)ambient temperature(power applied):-55 to+125 °C; (6)storage temperature, Tstg:-65 +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.)
