描述 Description

The MAX1084/MAX1085 10-bit analog-to-digital converters (ADCs) combine a high-bandwidth track/hold, a serial interface with high conversion speed, an internal +2.5V reference, and low power consumption. The MAX1084 operates from a single +4.5V to +5.5V supply; the MAX1085 operates from a single +2.7V to +3.6V supply.
The 3-wire serial interface connects directly to SPI?/QSPI?/MICROWIRE? devices without external logic. The devices use an external serial-interface clock to perform successive-approximation analog-to-digital conversions.
Low power combined with ease of use and small package size make these converters ideal for remote-sensor and data-acquisition applications, or for other circuits with demanding power consumption and space requirements. The MAX1084/MAX1085 are available in 8-pin SO packages.
These devices are pin-compatible, higher-speed versions of the MAX1242/MAX1243; for more information, refer to the respective data sheets.

簡介

MAX1084B屬于集成電路（IC）的模數轉換器（ADC）。由制造生產的MAX1084B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。
