NATIONAL SEMICONDUCTOR SETS NEW STANDARD FOR HIGH- SPEED, LOW-POWER VOLTAGE FEEDBACK AMPLIFIERS
- 3,600V/microsec Slew Rate at only 2.5 mA of supply current
- Wide 100MHz Bandwidth
- Easy-to-Use Voltage Feedback Topology
- High Common-Mode Rejection Ratio -- 110 dB
- Guaranteed Supply Voltage Range: +/-5V and +/-15V
SANTA CLARA, Calif., June 16, 1995 - A unity-gain voltage feedback amplifier featuring the industry's lowest power consumption has been designed and developed by National Semiconductor Corporation. National's newest addition to its technologies for shaping information, the LM6171, packs high performance at low power thanks to a new proprietary bi-polar process and a patented design. The IC's slew rate of 3,600V/µsec and 100 MHz bandwidth are achieved while consuming just 2.5 mA of supply current, making the device ideal for a wide variety of applications including multimedia broadcast systems, desktop video, scanners/copiers/fax imaging, test and measurement and ADSL/HDSL residential broadband.
"The industry sent device manufacturers a clear message -- that new analog devices must offer ease-of-use, high performance, low power consumption and low cost," observed Ed Tutman, National marketing manager "This device meets the market's criteria on all counts with its easy-to-use voltage feedback topology, an input stage with a proprietary architecture that makes the combination of high slew rate and low supply current possible."
The LM6171's high slew rate of 3,600 V/microsec and unity-gain bandwidth of 100 MHz allows fast settling for driving flash ADC or buffering DAC. Low distortion performance - - both AC and DC -- make the LM6171 amplifier ideal for most video and communications applications.
The device's +/-15V power supplies allow for large signal swings and gives greater dynamic range and signal-to-noise ratio. High output current drive and low Total Harmonic Distortion (THD) are an ideal combination for ADC/DAC systems. For portable applications, the LM6171 also operates at +/-5V.
