PRODUCT DESCRIPTION

The AD872A is a monolithic 12-bit, 10 MSPS analog-to-digital converter with an on-chip, high performance track-and-hold amplifier and voltage reference. The AD872A uses a multistage differential pipelined architecture with error correction logic to provide 12-bit accuracy at 10 MSPS data rates and guarantees no missing codes over the full operating temperature range. The AD872A is a redesigned version of the AD872 which has been optimized for lower noise. The AD872A is pin compatible with the AD872, allowing the parts to be used interchangeably as sys

tem requirements change.

AD872AJD屬于集成電路（IC） > 模數轉換器（ADC）。亞德諾半導體技術有限公司制造生產的AD872AJD模數轉換器（ADC）模數轉換器（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，然后將其轉換為數字信號。一般來說，數字輸出是二進制補碼二進制數，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數轉換器可按照位數、采樣率、輸入數、接口、轉換器數和架構（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。
