TC514集成電路（IC）的模擬前端（AFE）規(guī)格書PDF中文資料

TC514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TC514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)。

GENERAL DESCRIPTION

The TC500/500A/510/514 family are precision analog front ends that implement dual slope A/D converters having a maximum resolution of 17 bits plus sign. As a minimum, each device contains the integrator, zero crossing comparator and processor interface logic. The TC500 is the base (16 bit max) device and requires both positive and negative power supplies. The TC500A is identical to the TC500, except it has improved linearity allowing it to operate to a maximum resolution of 17 bits. The TC510 adds an on board negative power supply converter for single supply operation. The TC514 adds both a negative power supply converter and a 4 input differential analog multiplexer.
