CDB4349屬于開發(fā)板套件編程器的評估板-數(shù)模轉(zhuǎn)換器（DAC）。由凌云邏輯制造生產(chǎn)的CDB4349評估板 - 數(shù)模轉(zhuǎn)換器（DAC）該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗證的設(shè)計環(huán)境中對用于將數(shù)字?jǐn)?shù)據(jù)轉(zhuǎn)換為模擬格式的器件進(jìn)行性能或特性評估。重點(diǎn)器件涵蓋范圍從以適合學(xué)生或愛好者使用的方式實現(xiàn)的適度功能器件，到適合電信基礎(chǔ)設(shè)施應(yīng)用的高級器件。

Description

The CS4349 is a complete stereo digital-to-analog system including digital interpolation, 5th-order multi-bit delta-sigma digital-to-analog conversion, digital de-emphasis, volume control, channel mixing, and analog filtering. The advantages of this architecture include ideal linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature, tolerance to clock jitter, and a minimal set of external components.

The CS4349 supports all standard digital audio interface formats, including TDM.

The CS4349 is available in a 24-pin TSSOP package in both Commercial (-40° to +85°C) and Automotive grades (-40° to +105°C). The CDB4349 Customer Demonstration board is also available for device evaluation and imple mentation suggestions. Please refer to “Ordering Information” on page 40 for complete ordering information.

These features are ideal for cost-sensitive, two-channel audio systems, including DVD players and recorders, set top boxes, digital TVs, mini-component systems, musical instruments and automotive audio systems.
