DAC技術(shù)用語 (D/A Converters Defini

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 codechange exhibits 1⁄2 LSB differential non-linearity. Differentialnon-linearity may be expressed in fractional bits or as a percentageof full scale. A differential non-linearity greater than1 LSB will lead to a non-monotonic transfer function in aDAC.Gain Error (Full Scale Error): The difference between theoutput voltage (or current) with full scale input code and theideal voltage (or current) that should exist with a full scale inputcode.Gain Temperature Coefficient (Full Scale TemperatureCoefficient): Change in gain error divided by change in temperature.Usually expressed in parts per million per degreeCelsius (ppm/°C).Integral Nonlinearity (Linearity Error): Worst case deviationfrom the line between the endpoints (zero and full scale).Can be expressed as a percentage of full scale or in fractionof an LSB.LSB (Lease-Significant Bit): In a binary coded system thisis the bit that carries the smallest value or weight. Its value isthe full scale voltage (or current) divided by 2n, where n is theresolution of the converter.Monotonicity: A monotonic function has a slope whose signdoes not change. A monotonic DAC has an output thatchanges in the same direction (or remains constant) for eachincrease in the input code. the converse is true for decreasing codes.

100-15V TO 12V DCDC 原理圖 PCB BOM表

高的工作電壓高達100V N雙N溝道MOSFET同步驅(qū)動 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSFET. When in regulation, power is derived from the output for higher effi ciency.

USB TO Gigabit LAN網(wǎng)卡的設(shè)計與制作

畢業(yè)設(shè)計 USB TO Gigabit LAN 網(wǎng)卡隨著網(wǎng)絡(luò)技術(shù)飛速發(fā)展，多媒體的應(yīng)用越來越多，人們對網(wǎng)絡(luò)的要求也越來越高，為了適應(yīng)市場的需求，網(wǎng)卡出現(xiàn)了。它以其結(jié)構(gòu)簡單、成本低廉、兼容性強等諸多的優(yōu)越性得到了廣泛的應(yīng)用。由于網(wǎng)絡(luò)的應(yīng)用越來越廣泛，網(wǎng)卡的應(yīng)用也越來越多、功能越來越強大。開始時由于技術(shù)方面的限制，網(wǎng)卡只有10Mbps的吞吐量，由于網(wǎng)絡(luò)技術(shù)的發(fā)展，100Mbps吞吐量的網(wǎng)卡開始在市場上得到廣泛的應(yīng)用。而現(xiàn)在1000Mbps吞吐量的網(wǎng)卡的出現(xiàn)又給網(wǎng)絡(luò)的傳輸帶來了新的活力。論文中主要闡述了基于以太網(wǎng)的USB TO Gigabit LAN網(wǎng)卡的設(shè)計與制作。論文首先對以太網(wǎng)進行了介紹，緊接著講了網(wǎng)卡的基本知識。隨后又對USB TO Gigabit LAN網(wǎng)卡的電路設(shè)計和制作進行了詳細(xì)的描述。論文還包括了USB TO Gigabit LAN網(wǎng)卡的調(diào)試等內(nèi)容。

PICKIT™ 2 PROGRAMMER-TO-

PICKIT™ 2 PROGRAMMER-TO-GO USER GUIDE The PICkit 2 Programmer-To-Go functionality allows a PIC MCU memory image to be downloaded into the PICkit 2 unit for later programming into a specific PIC MCU. No software or PC is required to program devices once the PICkit 2 unit is set up for Programming-To-Go. A USB power source for the PICkit 2 is all that is needed.

PCA9541 2 to 1 I2C-bus master

The PCA9541 is a 2-to-1 I2C-bus master selector designed for high reliability dual masterI2C-bus applications where system operation is required, even when one master fails orthe controller card is removed for maintenance. The two masters (for example, primaryand back-up) are located on separate I2C-buses that connect to the same downstreamI2C-bus slave devices. I2C-bus commands are sent by either I2C-bus master and are usedto select one master at a time. Either master at any time can gain control of the slavedevices if the other master is disabled or removed from the system. The failed master isisolated from the system and will not affect communication between the on-line masterand the slave devices on the downstream I2C-bus.
