3 概要

AMC7836は高度に統合された、低消費電力のアナログ監視および制御ソリューションです。このデバイスには、21チャネル、12ビットのアナログ/デジタル・コンバータ(ADC)、出力範囲をプログラム可能な16の12ビット・デジタル/アナログ・コンバータ(DAC)、8つのGPIO、内部基準電圧、およびローカル温度センサ・チャネルが搭載されています。高レベルの統合により、部品数が大幅に減少し、閉ループ・システムの設計が簡素化するため、基板面積、サイズ、低消費電力が重要なマルチチャネル・アプリケーションに理想的です。

低消費電力、非常に高度な統合、広い動作温度範囲から、マルチチャネルRF通信システムに見られる、パワー・アンプ(PA)用のオールインワン、低コストのバイアス制御回路に適しています。柔軟なDAC出力範囲から、このデバイスはLDMOS、GaAs、GaNなど広範なトランジスタ・テクノロジのバイアス・ソリューションとして使用できます。AMC7836の一連の特長は、汎用の監視および制御システムにも同様に利益があります。

テキサス・インスツルメンツは、チャネル数、追加機能、コンバータ分解能についての要求が異なるアプリケーション向けに、アナログ監視および制御(AMC)製品の完全なファミリを用意しています。詳細については、www.ti.com/amcをご覧ください。
