The new Cirrus Logic®family of digital-to-analog converters, the
CS4344, CS4345, CS4346 and CS4348, delivers superior audio quality
while providing OEMs with the industry’s smallest, most cost-effective
192 kHz stereo DAC.
Helping reduce printed circuit board space requirements, the chips
are offered in a low profile 10-pin package that is 50 percent smaller
than Cirrus’ current eight-pin DAC family. Based on an advanced
multi-bit Delta-Sigma architecture, the CS4344 family provides a single-
ended output architecture and delivers -95 dB THD+N and a dynamic
range of 105 dB. The DACs operate from a single +3.3 V or +5 V
power supply and include value-added features such as patented
automatic sample-rate detection, on-chip digital de-emphasis and
Cirrus Logic’s Popguard technology to eliminate power cycling clicks
and pops, which further reduces the number of external components
required.
The CS4344, CS4345, CS4346, and CS4348 differ only in the serial
audio interface format they support, which includes I2S, left-justified,
and 24-bit and 16-bit right-justified, respectively. Existing Cirrus
Logic customers have a simple upgrade path because the CS4344
family is functionally compatible with other popular value-line DACs
from Cirrus Logic, including the CS4334, CS4340, and CS4340A.
The CS4344 family strengthens Cirrus’ industry leading D/A converter
product line and provides manufacturers a simple, small, and cost-
effective solution, which is precisely what you need to get premium
audio products to market fast. You will have to look closely to see this
tiny 10-pin DAC, but your ears will easily discern the remarkable
sound quality that this DAC delivers.
