  • Description

    The LMH6643HA is a wideband DC-coupled voltage-controlled gain stage followed by a high-speed current feedback operational amplifier. It is specifically designed to drive low impedance loads. With a gain adjustment range of 80 dB up to 10 MHz, the gain control input voltage, VG, can be varied to achieve the desired gain. The maximum gain is set by external components, and the gain can be reduced to cutoff. The power consumption of the LMH6643HA is 110 mW, and it has a speed of 150 MHz with a gain control bandwidth (BW) of 100 MHz. The DC offset voltage at the output is less than 55 mV across the entire gain control voltage range. The LMH6643HA also offers high device-to-device gain matching within ±0.5 dB at maximum gain. It is a versatile component that can be easily configured as an inverting amplifier due to its near-ideal input characteristics such as low input bias current, low offset, and low pin 3 resistance.
