Starting at an unrivaled offering of $14.95 in quantities as low as 1,000 units, this ADC is ideal for demanding applications such as digital mixing consoles, multi-track recording systems, A/V receivers, and DVD recorders, which all require wide dynamic range, negligible distortion, and the best sound quality available. The CS5381 uses a 5th-order, multi-bit ∆Σ modulator along with digital filtering and decimation to eliminate the need for an external anti-alias filter. The CS5381 features a differential architecture that provides excellent noise rejection and performs sampling, analog-todigital conversion and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 200 kHz per channel. Power consumption of a mere 315 mW is less than half of competing solutions and can simplify the design for systems that use multiple devices. Also, this ADC is pin-compatible with the CS5361 and CS5351, so current Cirrus customers can upgrade product performance with no need to modify their existing board design. Actual Size The CS5381 sets a new standard for price/performance, so flagship sound quality and analog performance no longer cost a fortune!
