LMH6643QMM/NOPB 3 Description

The LMH664X family true single supply voltagefeedback amplifiers offer high speed (130 MHz), lowdistortion (−62 dBc), and exceptionally high outputcurrent (approximately 75 mA) at low cost and withreduced power consumption when compared againstexisting devices with similar performance.Input common mode voltage range extends to 0.5 Vbelow V− and 1 V from V+. Output voltage rangeextends to within 40mV of either supply rail, allowingwide dynamic range especially desirable in lowvoltage applications. The output stage is capable ofapproximately 75 mA in order to drive heavy loads.Fast output Slew Rate (130 V/µs) ensures largepeak-to-peak output swings can be maintained evenat higher speeds, resulting in exceptional full powerbandwidth of 40 MHz with a 3-V supply. Thesecharacteristics, along with low cost, are ideal featuresindustrial and commercialfor a multitude ofapplications.Device Information(1)

LMH6643QMM/NOPB 5 Description (continued)

Careful attention has been paid to ensure device stability under all operating voltages and modes. The result is avery well behaved frequency response characteristic (0.1dB gain flatness up the 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, andhigh 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 heavyloads (150Ω) and throughout the output voltage range. The LMH664X family is offered in single (LMH6642) anddual (LMH6643).
