AD9280ARS集成電路（IC）的模數(shù)轉換器（ADC）規(guī)格書PDF中文資料

AD9280ARS屬于集成電路（IC）的模數(shù)轉換器（ADC）。由亞德諾半導體技術有限公司制造生產的AD9280ARS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。

PRODUCT DESCRIPTION

The AD9280 is a monolithic, single supply, 8-bit, 32 MSPS analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference. The AD9280 uses a multistage differential pipeline architecture at 32 MSPS data rates and guarantees no missing codes over the full operating temperature range.

The input of the AD9280 has been designed to ease the development of both imaging and communications systems. The user can select a variety of input ranges and offsets and can drive the input either single-ended or differentially.

The sample-and-hold amplifier (SHA) is equally suited for both multiplexed systems that switch full-scale voltage levels in successive channels and sampling single-channel inputs at frequencies up to and beyond the Nyquist rate. AC-coupled input signals can be shifted to a predetermined level, with an onboard clamp circuit. The dynamic performance is excellent.

The AD9280 has an onboard programmable reference. An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of the application.
