TLC0838是8位串行8通道模数转换器,它与TLC0834、TLC0832、TLC0831,各项性能除通道数、引脚数不同外,其它方面基本一致。它可以与美国国家半导体公司的ADC083X系列产品直接代换。单片机系统特别是嵌入式控制系统PCB板的尺寸要求很严格,所以要求设计者既要考虑完成设计要求,又不能超过体积。根据输出的信号格式,比较常用的A/D转换方式可分为并行A/D和串行A/D。并行方式一般在转换后可直接接收,但芯片的引脚比较多;串行A/D转换方式所用芯片引脚少、封装小,在PCB板上占用的空间
TLC0838 is an 8-bit serial 8-channel analog-to-digital converter. It is compatible with TLC0834, TLC0832, and TLC0831 in various aspects except for the number of channels and pins. It can be directly replaced with the National Semiconductor ADC083X series. SCM system especially embedded control system PCB board size requirements are very strict, so designers are required to consider both the completion of design requirements, but also can not exceed the volume. According to the output signal format, more commonly used A / D conversion can be divided into parallel A / D and serial A / D. The parallel mode can be directly received after conversion, but the chip pins are more; serial A / D conversion chip pin used less, small package, the space occupied on the PCB board
