MCP3903集成電路（IC）的模擬前端（AFE）規(guī)格書PDF中文資料

MCP3903屬于集成電路（IC）的模擬前端（AFE）。由微芯科技股份有限公司制造生產(chǎn)的MCP3903模擬前端（AFE）模擬前端 (AFE) 是一種用于信號(hào)調(diào)節(jié)的半導(dǎo)體器件，由模擬放大器、運(yùn)算放大器、濾波器和集成電路構(gòu)成。這種可配置功能塊能連接各種傳感器。分辨率范圍從 8 位至 42 位不等，通道數(shù)范圍為 1 至 256 個(gè)。

Description

The MCP3903 is a six-channel Analog Front End (AFE) containing three pairs made out of two synchronous

sampling Delta-Sigma Analog-to-Digital Converters (ADC) with PGA, a phase delay compensation block, internal voltage reference, and high-speed 10 MHz SPI compatible serial interface. The converters contain a proprietary dithering algorithm for reduced idle tones and improved THD.
