LMH6503
Wideband, Low Power, Linear Variable Gain Amplifier
General Description
The LMH
voltage controlled gain stage followed by a high-speed cur-
rent feedback Op Amp which can directly drive a low imped-
ance 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
tested and the tolerance is guaranteed. 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 opera-
tion, 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.
