The LMH5485-SP is a radiation , low-power, voltage-feedback, fully differential amplifier (FDA) with an input common-mode range below the negative rail, and rail-to-rail output. Designed for power sensitive data acquisition systems where high density is critical in a high-performance analog-to-digital converter (ADC) or digital-to-analog converter (DAC) interface designs.

The LMH5485-SP features the negative-rail input required when interfacing a DC-coupled, ground-centered, source signal. This negative-rail input, with rail-to-rail output, allows for easy interface between single-ended, ground-referenced, bipolar signal sources and a wide variety of successive approximation register (SAR), delta-sigma (ΔΣ), or pipeline ADCs using only a single 2.7 V to 5.1 V power supply. LMH5485-SP also offers excellent DC precision for such ADC driving applications and is characterized for operation over the wide temperature range of –55°C to +125°C.

LMH5485-SP-EVM — 適用於 850-MHz 全差動放大器的 LMH5485-SP 評估模組

LMH5485-SP-EVM 是一款通用、未組裝的印刷電路板 (PCB)，專為評估採用 HKX (CFP-8) 封裝之 LMH5485-SP 時提供最佳佈線而設計。LMH5485-SP 為一抗輻射 (RHA) 負軌輸入、軌至軌輸出 (RRO)、精密、850-MHz 全差動放大器。開始評估時只需幾個零組件。為了避免寄生零組件電感，電路板只接受表面裝貼電阻器和電容器。此 EVM 設計適用於輸入和輸出端的 50-Ω 實驗室設備，以及輸入和輸出端的換衡器配置，可在單端和差動訊號之間進行簡單轉換。
