General Description

The CS5381 is a complete analog-to-digital converter for digital audio systems. It performs sampling, analogto-digital conversion, and anti-alias filtering - generating 24-bit values for both left and right inputs in serial form at sample rates up to 216 kHz per channel.

The CS5381 uses a 5th-order, multi-bit delta-sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter. The ADC uses a differential architecture which provides excellent noise rejection.

The CS5381 is available in 24-pin TSSOP and SOIC packages for Commercial grade (-10° to +70° C). The CDB5381 Customer Demonstration board is also available for device evaluation and implementation suggestions.

The CS5381 is ideal for audio systems requiring wide dynamic range, negligible distortion, and low noise - such as A/V receivers, DVD-R, CD-R, digital mixing consoles, and effects processors.

ABSOLUTE MAXIMUM RATINGS

(GND = 0 V, All voltages with respect to ground.) (Note 1)

Notes:

1. Operation beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes.

2. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause SRC latch-up.

3. The maximum over/under voltage is limited by the input current.
