The LMH5485-SP is a radiation-hardened assured, low-power, voltage-feedback, fully differential amplifier (FDA). This device is able to achieve a high gain bandwidth product (GBWP) of 850MHz to maintain excellent distortion performance over a wide range of frequencies. This wide bandwidth range is also achieved with a relatively low power consumption of 10.1mA and broadband voltage noise of 2.4nV/√Hz. These features make the LMH5485-SP an excellent choice for power-sensitive data acquisition systems with frequencies > 10MHz that require both the best signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR).

The LMH5485-SP features the negative-rail input required when interfacing with a dc-coupled, ground-centered source signal. This negative-rail input with a 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 2.7V to 5.4V power supply. The LMH5485-SP also features a low offset voltage drift of ±0.5µV/°C to maintain excellent dc performance over a wide temperature range of –55°C to +125°C.
