3 Description

The ADC364x family of devices are low-noise,

ultra-low power, 14-bit, 10-MSPS to 65-MSPS

dual-channel, high-speed analog-to-digital converters

(ADCs). Designed for low power consumption, these

devices deliver a noise spectral density of –155

dBFS/Hz, combined with excellent linearity and

dynamic range. The ADC364x offers very good dc

precision, together with IF sampling support, which

make the device an excellent choice for a wide range

of applications. High-speed control loops benefit from

the short latency of only one clock cycle. The ADC

consumes only 72 mW/ch at 65 MSPS, and power

consumption scales well with lower sampling rates.

The ADC364x use a DDR or serial CMOS interface to

output the data offering lowest power digital interface,

together with flexibility to minimize the number of

digital interconnects. These devices are a pin-to-pin

compatible family with different speed grades. These

devices support the extended industrial temperature

range of –40 to +105?C.

ADC3642屬于集成電路（IC） > 模數(shù)轉(zhuǎn)換器（ADC）。美國(guó)德州儀器公司制造生產(chǎn)的ADC3642模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號(hào)。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。
