The INA200-Q1, INA201-Q1, and INA202-Q1 (INA20x-Q1) are low-side or high-side, current-shunt monitors with voltage output. The INA20x-Q1 devices can sense drops across shunts at common-mode voltages from –16V to +80V. The INA20x-Q1 are available with three output voltage scales: 20V/V, 50V/V, and 100V/V, with up to a 500kHz bandwidth.

The INA20x-Q1 also incorporates an open-drain comparator and internal reference that provides a 0.6V threshold. External dividers set the current trip point. The comparator includes a latching capability, and can be made transparent by grounding (or leaving open) the RESET pin.

The INA20x-Q1 operates from a single 2.7V to 18V supply, drawing a maximum of 1800µA supply current. These devices are available in the very small VSSOP-8 package. Specifications for all devices extend over the operating temperature range of –40°C to +125°C.

ANALOG-ENGINEER-CALC — PC software analog engineer's calculator

類比工程師的計算機旨在加速類比電路設計工程師定期使用的許多重複計算。此基於 PC 的工具提供圖形介面,列出各種常見計算,從使用回饋電阻器設定運算放大器增益到選擇適當的電路設計元件以穩定類比數位轉換器 (ADC) 驅動緩衝電路。

除了作為獨立工具使用外,此計算機還與類比工程師口袋參考中描述的概念相得益彰。

TIDA-00271 — 適用遠端攝影機和雷達模組的 ADAS 感測器互連參考設計基板

ADAS 感測器互連電路板適用於需要將攝影機、光達或雷達模組等遠端感測器連接至中央處理 ECU 的應用。電路板支援高達 3 個同軸和 1 個 LVDS 雙絞線資料輸入,以及 3 個 FMC 纜線和 1 個電路板至電路板連接器,以做為處理 ECU 的資料輸出。  透過同軸連接器(SMB 標準)連接的攝影機或其他感測器模組,直接透過互連板的同軸纜線(同軸電纜供電)供電。由於所有 IC 皆有獨立完整電源解決方案,且板載同軸纜線供電,因此單一汽車電池或類似寬電壓供應器可直接連接至 ADAS 感測器互連電路板上的電源接頭。板載 uC 和 LIN 介面可控制和配置互連電路板,以及隨插即用操作。
