LMH6504
Wideband, Low Power, Variable Gain Amplifier
General Description
The LMH
6504 is a wideband DC coupled voltage con-
trolled gain stage followed by a high-speed current feedback
OpAmp which can directly drive a low impedance load. Gain
adjustment range is 80 dB for up to 10 MHz by varying the
gain control input voltage, V
G
.
Maximum gain is set by external components, and the gain
can be reduced all the way to cut-off. Power consumption is
110 mW with a speed of 150 MHz and a gain control band-
width (BW) of 150 MHz. Output referred DC offset voltage is
less than 55 mV over the entire gain control voltage range.
Device-to-device gain matching is within
±
0.42 dB at maxi-
mum gain. Furthermore, gain is tested and guaranteed over
a wide range. The output current feedback Op Amp allows
high frequency large signals (Slew Rate
>
1500 V/μs) and
can also drive a heavy load current (60 mA). Near ideal input
characteristics (i.e. low input bias current, low offset, low pin
3 resistance) enable the device to be easily configured as an
inverting amplifier as well (see Application Information sec-
tion for details).
To provide ease of use when working with a single supply,
V
range is set to be from 0V to +2V relative to the ground
pin potential (pin 4). V
input impedance is high in order to
ease drive requirement. In single supply operation, the
ground pin is tied to a "virtual" half supply.
LMH6504 gain control is linear in dB for a large portion of the
total gain control range. This makes the device suitable for
AGC applications. For linear gain control applications, see
LMH6503 data sheet.
The combination of minimal external components and small
outline packages (SO8 and MSOP8) allows the LMH6504 to
be used in space-constrained applications.
