5 Description (continued)
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 (0.1dB gain flatness up the 12MHz under 150Ω load and A_V
= +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.
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 LMH664X family is offered in single (LMH6642) and
dual (LMH6643).
