This application note describes a Linear Technology "Half-Flash" A/D converter, the LTC1099, being connected to a 256 element line scan photodiode array. This technology adapts itself to handheld (i.e., low power) bar code readers, as well as high resolution automated machine inspection applicatio ...

The LM20, LM45, LM50, LM60, LM61, and LM62 are analog output temperature sensors. They have various output voltage slopes (6.25mV/°C to 17mV/°C) and power supply voltage ranges (2.4V to 10V).The LM20 is the smallest, lowest power consumption analog output temperature sensor National Semiconductor ...

Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codec ...

Abstract: We don't expect manufacturers to produce clothes that in one size that fits everyone. In thesame way, one ESD component can't solve all issues—each application has different ESD requirements.Knowing that "one size fits all" cannot apply to power design, the power designer, ...

  The makers of handheld medical, industrial and consumerdevices use a wide variety of high resolution, small tomedium sized color TFT LCD displays. The power supplydesigners for these displays must contend with shrinkingboard area, tight schedules, and variations in displaytypes and featur ...

　　为了使音频信号分析仪小巧可靠，成本低廉，设计了以2片MSP430F1611单片机为核心的系统。该系统将音频信号送入八阶巴特沃兹低通滤波器，对信号进行限幅放大、衰减、电平位移、缓冲，并利用一单片机负责对前级处理后的模拟信号进行采样，将采集得到的音频信号进行4 096点基2的FFT计算，并对信号加窗函数提高分辨率，另 ...

为了解决磁放大器性能测试过程中，需要对其供给不同数值恒定电流的问题，设计了一种基于DAC7512和单片机的数控恒流源系统。该系统采用AT89C51作为主控器件，将计算机发送的电流控制字命令转换为D/A转换器控制字，通过模拟SPI通信接口，写D/A控制字到DAC7512，从而控制其输出相应数字电压值，经差动缩放电路、电压/电路变换 ...

Luminary Micro provides an analog-to-digital converter (ADC) module on some members of theStellaris microcontroller family. The hardware resolution of the ADC is 10 bits; however, due to noiseand other accuracy-diminishing factors, the true accuracy is less than 10 bits. This application noteprovide ...

8.1  模拟接口概述单片机的外部设备不一定都是数字式的，也经常会和模拟式的设备连接。     例如单片机来控制温度、压力时，温度和压力都是连续变化的，都是模拟量，在单片机与外部环境通信的时候，就需要有一种转换器来把模拟信号变为数字信号，以便能够输送给单片机进行处理。而单片机送出的控 ...
