一 概述

TM7711 是應(yīng)用于電子秤低頻測(cè)量的單通道模擬前端。該器件可以接受直接來(lái)自傳感器的低電平的輸入信號(hào)，然后產(chǎn)生串行的數(shù)字輸出。利用 Σ-Δ 轉(zhuǎn)換技術(shù)實(shí)現(xiàn)了 24 位無(wú)丟失代碼性能。通過選定的輸入信號(hào)被送到一個(gè)基于模擬調(diào)制器的增益可編程專用前端。片內(nèi)數(shù)字濾波器處理調(diào)制器的輸出信號(hào)，通過通信口發(fā)命令可調(diào)節(jié)濾波器的截止點(diǎn)和輸出更新速率，從而對(duì)數(shù)字濾波器的第一個(gè)陷波進(jìn)行編程。TM7711 只需 2.6~5.5V 單電源供電。TM7711 是全差分模擬輸入，帶有一個(gè)基準(zhǔn)輸入。TM7711 是一款用于高精度電子秤系統(tǒng)的理想產(chǎn)品，由于采用特殊的結(jié)構(gòu)確保器件具有極低功耗，并且內(nèi)建有掉電模式以減少待機(jī)功耗。該芯片還具有集成度高、響應(yīng)速度快、抗干擾強(qiáng)等優(yōu)點(diǎn)，可以大大降低電子秤系統(tǒng)的整機(jī)成本，提高整機(jī)系統(tǒng)的性能和可靠性。

三 典型應(yīng)用

四 管腳信息

五 串口通信

串口通訊線由管腳 PD_SCK 和 DOUT 組成，用來(lái)輸出數(shù)據(jù)，選擇輸出數(shù)據(jù)速率和輸入信號(hào)。當(dāng)數(shù)據(jù)輸出管腳 DOUT 為高電平時(shí)，表明 A/D 轉(zhuǎn)換器還未準(zhǔn)備好輸出數(shù)據(jù)，此時(shí)串口時(shí)鐘輸入信號(hào) PD_SCK 應(yīng)為低電平。當(dāng) DOUT 從高電平變低電平后，PD_SCK 應(yīng)輸入 25 至 27 個(gè)不等的時(shí)鐘脈沖（圖 3）。其中第一個(gè)時(shí)鐘脈沖的上升沿將讀出輸出 24 位數(shù)據(jù)的最高位（MSB），直至第 24 個(gè)時(shí)鐘脈沖完成，24 位輸出數(shù)據(jù)從最高位至最低位逐位輸出完成。第 25 至 27 個(gè)時(shí)鐘脈沖用來(lái)選擇下一次 A/D 轉(zhuǎn)換的輸出數(shù)據(jù)速率和輸入信號(hào)，參見表 4。PD_SCK 的輸入時(shí)鐘脈沖數(shù)不應(yīng)少于 25 或多于27，否則會(huì)造成串口通訊錯(cuò)誤。當(dāng) A/D 轉(zhuǎn)換器的輸入信號(hào)或輸出數(shù)據(jù)速率改變時(shí)，A/D 轉(zhuǎn)換器需要 4 個(gè)數(shù)據(jù)輸出周期才能穩(wěn)定。DOUT 在 4 個(gè)數(shù)據(jù)輸出周期后才會(huì)從高電平變低電平，輸出有效數(shù)據(jù)。

歡迎同學(xué)們走進(jìn)AmazIOT知識(shí)庫(kù)的世界！

這里是為物聯(lián)網(wǎng)人構(gòu)建的技術(shù)應(yīng)用百科，以便幫助你更快更簡(jiǎn)單的開發(fā)物聯(lián)網(wǎng)產(chǎn)品。

Cellular IoT Wiki初心：

在我們長(zhǎng)期投身于蜂窩物聯(lián)網(wǎng) ODM/OEM 解決方案的實(shí)踐過程中，一直被物聯(lián)網(wǎng)技術(shù)碎片化與產(chǎn)業(yè)資源碎片化的問題所困擾。從產(chǎn)品定義、芯片選型，到軟硬件研發(fā)和測(cè)試，物聯(lián)網(wǎng)技術(shù)的碎片化以及產(chǎn)業(yè)資源的碎片化，始終對(duì)團(tuán)隊(duì)的產(chǎn)品開發(fā)交付質(zhì)量和效率形成制約。為了減少因物聯(lián)網(wǎng)碎片化而帶來(lái)的重復(fù)開發(fā)工作，我們著手對(duì)物聯(lián)網(wǎng)開發(fā)中高頻應(yīng)用的技術(shù)知識(shí)進(jìn)行沉淀管理，并基于 Bloom OS 搭建了不同平臺(tái)的 RTOS 應(yīng)用生態(tài)。后來(lái)我們發(fā)現(xiàn)，很多物聯(lián)網(wǎng)產(chǎn)品開發(fā)團(tuán)隊(duì)都面臨著相似的困擾，于是，我們決定向全體物聯(lián)網(wǎng)行業(yè)開發(fā)者開放奇跡物聯(lián)內(nèi)部沉淀的應(yīng)用技術(shù)知識(shí)庫(kù) Wiki，期望能為更多物聯(lián)網(wǎng)產(chǎn)品開發(fā)者減輕一些重復(fù)造輪子的負(fù)擔(dān)。

Cellular IoT Wiki沉淀的技術(shù)內(nèi)容方向如下：

奇跡物聯(lián)的業(yè)務(wù)服務(wù)范圍：基于自研的NB-IoT、Cat1、Cat4等物聯(lián)網(wǎng)模組，為客戶物聯(lián)網(wǎng)ODM/OEM解決方案服務(wù)。我們的研發(fā)技術(shù)中心在石家莊，PCBA生產(chǎn)基地分布在深圳、石家莊、北京三個(gè)工廠，滿足不同區(qū)域&不同量產(chǎn)規(guī)模&不同產(chǎn)品開發(fā)階段的生產(chǎn)制造任務(wù)。跟傳統(tǒng)PCBA工廠最大的區(qū)別是我們只服務(wù)物聯(lián)網(wǎng)行業(yè)客戶。

連接我們，和10000+物聯(lián)網(wǎng)開發(fā)者一起降低技術(shù)和成本門檻

讓蜂窩物聯(lián)網(wǎng)應(yīng)用更簡(jiǎn)單~~
