LMH6643EP Datasheet | National Semiconductor

Description The LMH664XEP family true single supply voltage feedback amplifiers offer high speed (130MHz), low distortion (- 62d Bc), and exceptionally high output current (approximately 75m A) at low cost and with reduced power consumption when pared against existing devices with similar performance. Input mon mode voltage range extends to 0.5V below V- and 1V from V+. Output voltage range extends to within 40m V of either supply rail, allowing wide dynamic range especially desirable in low voltage applications. The output stage is capable of approximately 75m A in order to drive heavy loads. Fast output Slew Rate (130V/µs) ensures large peak-to-peak output swings can be maintained even at higher speeds, resulting in exceptional full power bandwidth of 40MHz with a 3V supply. These characteristics, along with low cost, are ideal features for a multitude of industrial and mercial applications. Careful attention has been paid to ensure device stability under all operating voltages and modes. The result is a very well behaved frequency response characteristic (0.1d B gain flatness up the 12MHz under 150Ω load and AV = +2) with minimal peaking (typically 2d B maximum) for any gain setting and under both heavy and light loads. This along with fast settling time (68ns) and low distortion allows the device to operate well in ADC buffer, and high frequency filter applications as well as other applications. This device family offers professional quality video performance with low DG (0.01%) and DP (0.01˚) characteristics. Differential Gain and Differential Phase characteristics are also well maintained under heavy loads (150Ω) and throughout the output voltage range. The LMH664XEP family is offered in single (LMH6642EP), dual (LMH6643EP), and quad (LMH6644EP) options. See ordering information for packages offered.
