AD6600AST集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD6600AST屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD6600AST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。

PRODUCT DESCRIPTION

The AD6600 mixed-signal receiver chip directly samples signals at analog input frequencies up to 250 MHz. The device includes two input channels, each with 1 GHz input amplifiers and 30 dB of automatic gain-ranging circuitry. Both channels are sampled with a 450 MHz track-and-hold followed by an 11-bit, 20 MSPS analog-to-digital converter. Digital RSSI outputs, an A/B channel indicator, a 2× Clock output, references, and con trol circuitry are all on-chip. Digital output signals are two’s complement, CMOS-compatible and interface directly to 3.3 V or 5 V digital processing chips.
