GENERAL DESCRIPTION

The AD9237 is a family of monolithic, single 3 V supply, 12-bit, 20 MSPS/40 MSPS/65 MSPS analog-to-digital converters (ADC). This family features a high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9237 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 20 MSPS/40 MSPS/65 MSPS data rates and guarantees no missing codes over the full operating temperature range.

FEATURES

Ultralow power 85 mW at 20 MSPS 135 mW at 40 MSPS 190 mW at 65 MSPS

SNR = 66 dBc to Nyquist at 65 MSPS

AD9237BCPZRL7-20屬于集成電路（IC） > 模數(shù)轉換器（ADC）。亞德諾半導體技術有限公司制造生產(chǎn)的AD9237BCPZRL7-20模數(shù)轉換器（ADC）模數(shù)轉換器（ADC、A/D 或 A 轉 D）對模擬信號進行采樣，例如由麥克風采集的聲音或傳感器的輸出，然后將其轉換為數(shù)字信號。一般來說，數(shù)字輸出是二進制補碼二進制數(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)轉換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉換器數(shù)和架構（例如自適應增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進行選擇。
