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.
