PCM1821IRTER character

● stereo is high-powered ADC:

Microphone of 2 passageways imitate is inputted or circuit is inputted

● ADC circuitry and microphone poor cent input function:

PCM1820 dynamic limits:

123dB, enable dynamic limits booster

113dB, ban with dynamic limits booster

PCM1821 dynamic limits: 106dB

THD+N: – 95dB

● ADC difference divides input of 2VRMS full span

● ADC sampling is led (FS) = 8kHz comes 192kHz

● hardware brings a foot to control configuration

Phasic or ● linear is low defer filter is optional

The frequency with agile ● strings together travel data interface:

Advocate or from interface optional

32, 2 passageways TDM

32, 2 passageways I2S

● frequency clock loses miss the opportunity to cut off the power automatically

● is compositive high-powered frequency PLL

● only power source moves: 3.3V

● I/O power source moves: 3.3V or 1.8V

Power comsumption of depressive of report of power source of ● 3.3V AVDD:

19.6mW/ passageway is below 16kHz sampling rate

21.3mW/ passageway is below 48kHz sampling rate

PCM1821IRTER explains

Is PCM1821IRTER a high-powered, Burr-Brown? Frequency modulus converter (ADC) , supportable most the synchronous sampling of two imitate passageway. This parts of an apparatus supports the circuitry that need branch and microphone input, have signal of 2VRMS full span, compositive Suo Xianghuan (filter divides PLL) and dc to connect filter high (HPF) , support the sampling rate that is as high as 192kHz. This parts of an apparatus backs time multichannel answer is used (TDM) or I2S frequency format, and hardware brings crural n optional. In addition, PCM182x still supports choice of mode of principal and subordinate, realize operation of interface of frequency bus line thereby. These compositive high-powered character, and the function that uses power supply of 3.3 V only power source, make this parts of an apparatus special sensitive, space bears the cost in applying to recording of far field microphone to apply bounds frequency system.

The limits of rated job temperature of PCM1821IRTER is – 40 ° C comes + 125 ° C, and use the 20 WQFN that cite a base enclose.
