National LMH6642/6643/6644 handbook
The LMH664X family is a 3V single-supply voltage feedback amplifier with high speed (130MHz), low distortion (-62dBc), and exceptionally high output current (approximately 75mA), at a low cost and reduced power consumption compared to existing devices with similar performance. The input common mode voltage range extends to 0.5V below V- and 1V above V+. The output voltage range extends to within 40mV of either supply rail, allowing wide dynamic range, especially desirable in low voltage applications. The output stage is capable of approximately 75mA 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 an 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 commercial applications. Device stability has been carefully considered under all operating voltages and modes. The result is a very well-behaved frequency response characteristic (0.1dB gain flatness up to 12MHz under 150Ω load and AV = +2) with minimal peaking (typically 2dB 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.
