Datasheet

National Semiconductor Corp. today introduced the industry’s first wideband 900 MHz fully differential amplifier to include a programmable output limiting clamp for protecting analog-to-digital converters (ADC) and other downstream circuitry from over-voltage events. The amplifier’s integrated clamp provides improved distortion, higher bandwidth and clamping accuracy compared with existing amplifiers that must use external discrete clamping circuits to provide the same protection.

The LMH6553 operates over the -40 degrees C to 125 degrees C temperature range and is well-suited for processing wide dynamic-range signals in automotive safety applications, including collision avoidance, lane departure and back-up warning systems. A member of National’s PowerWise® family of energy-efficient products, the LMH6553 features 900 MHz unity-gain bandwidth while operating on only 29 mA of supply current. This results in an industry-leading power-to-performance ratio of 32 uA per MHz.

Additionally, National provides designers with a variety of signal path solutions by pairing the LMH6553 with one of more than 40 differential input 8-bit to 14-bit ADCs featuring sampling rates up to 1 giga samples per second (GSPS). These ADCs include the ADC08D1000, ADC10080, ADC12C170 and ADC14DS105.
