The LMH6618 and LMH6619 (dual) (single shutdown) are 130 MHz rail-to-rail input and output amplifiers designed to drive complex ADCs and video loads in a wide range of applications that require high speed, low supply current, low noise, capability and ease of use. The operating voltage range is from 2.7V to 11V, and the supply current is typically 1.25 mA per channel at 5V. LMH6618 and LMH6619 PowerWise members ™ home and have an excellent power-performance ratio.
The design topology of the voltage feedback amplifier provides balanced input and high open-loop gain for ease of use and accuracy of active filter design, such as application. The offset voltage is typically 0.1 mV and 0.01% establish time of 120 ns combined at 100 kHz with 100 dBc SFDR, and part of the input buffer is suitable for ADCs using popular 8-bit, 10-bit, 12-bit, and 14-bit supersampled ADCs.
The input common mode range exceeds the power rail by 200 mV. A 5V single supply provides a 150Ω load swing with a 37 mV swing on the ground rail and a 1kΩ load swing 77 MV on the railway, providing true single-supply operation and maximum signal dynamic low-power rail range. The amplifier's output source and sink 35 mA and 30 pF load driver without external compensation.
LMH6618 low effective disable pin, resulting in a reduced supply current of 72μA and a space-saving 6-pin TSOT23 package. LMH6619 are available in an 8-pin SOIC package. LMH6618 and LMH6619 extend industrial grade temperatures from -40°C to +125°C.
