Over-voltage protection

  • 15-Nov-2008 08:46 EST


The PowerWise LMH6553 from National Semiconductor is a fully differential amplifier that includes a programmable output-limiting clamp for protecting analog-to-digital converters and other downstream circuitry from over-voltage events. It features 900 MHz unity-gain bandwidth while operating on 29 mA of supply current. The amplifier’s integrated clamp provides improved distortion, higher bandwidth, and clamping accuracy compared with existing amplifiers that use external discrete clamping circuits to provide the same protection. Operating over the -40 to 125°C (-40 to 257°F) temperature range, the LMH6553 is suitable for processing wide dynamic-range signals in automotive safety applications, including collision avoidance, lane departure, and backup warning systems.
