LMH6503MA/NOPB General Description

The LMH6503 is a wideband, DC coupled, differential input, voltage controlled gain stage followed by a high-speed current feedback Op Amp which can directly drive 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 V_G is tested and the tolerance is ensured. The output current feedback Op Amp allows high frequency large signals (Slew Rate = 1800V/μs) 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 (or to a virtual half-supply in single supply application). Inverting or non-inverting gains could be obtained by choosing one input polarity or the other.

To further increase versatility when used in a single supply application, gain control range is set to be from −1V to +1V relative to pin 11 potential (ground pin). In single supply operation, this ground pin is tied to a "virtual" half supply. Gain control pin has high input impedance to simplify its drive requirement. Gain control is linear in V/V throughout the gain adjustment range. Maximum gain can be set to be anywhere between 1V/V to 100V/V or higher. For linear in dB gain control applications, see LMH6502 datasheet.

The LMH6503 is available in the SOIC-14 and TSSOP-14 package.
