The CS5381 analog-to-digital converter is ideal for designers who
need to deliver premium audio performance at a competitive price.
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!
