LMH6503MA/NOPB

The LMH6503MA/NOPB is a wideband low power linear Variable-gain Amplifier which can directly drives a low impedance load. Gain adjustment range is more than 70dB for up to 10MHz. Maximum gain is set by external components and the gain can be reduced all the way to cut-off. Power consumption is 370mW with a speed of 135MHz. Output referred DC offset voltage is less than 350mV over the entire gain control voltage range. Device-to-device Gain matching is within 0.7dB at maximum gain. Furthermore, gain at any VG is tested and the tolerance is ensured. The output current feedback op-amp allows high frequency large signals and can also drive heavy load current (75mA). Differential inputs allow common mode rejection in low level amplification or in applications where signals are carried over relatively long wires. For single ended operation, the unused input can easily be tied to ground. Inverting or non-inverting gains could be obtained by choosing one input polarity or the other.

Avvertenze

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
