LMH6505 Wideband, Low Power, Linear-in-dB, Variable Gain Amplifier  
Check for Samples: LMH6505  
Near ideal input characteristics (i.e. low input bias

FEATURES  
current, low offset, low pin 3 resistance) enable the  
device to be easily configured as an inverting  
amplifier as well.

VS = ±5V, TA = 25°C, RF = 1 kΩ, RG = 100Ω, RL =  
100Ω, AV = AVMAX = 9.4 V/V, Typical Values  
Unless Specified.  
To provide ease of use when working with a single  
supply, the VG range is set to be from 0V to +2V  
relative to the ground pin potential (pin 4). VG input  
impedance is high in order to ease drive requirement.  
In single supply operation, the ground pin is tied to a  
"virtual" half supply.

−3 dB BW 150 MHz  
Gain Control BW 100 MHz  
Adjustment Range (<10 MHz) 80 dB  
Gain Matching (Limit) ±0.50 dB  
Supply Voltage Range 7V to 12V  
Slew Rate (Inverting) 1500 V/μs  
Supply Current (No Load) 11 mA  
Linear Output Current ±60 mA  
Output Voltage Swing ±2.4V  
The LMH6505’s gain control is linear in dB for a large  
portion of the total gain control range from 0 dB down  
to −85 dB at 25°C, as shown below. This makes the  
device suitable for AGC applications. For linear gain  
control applications, see the LMH6503 datasheet.  
The LMH6505 is available in either the 8-Pin SOIC or  
the 8-Pin VSSOP package. The combination of  
minimal external components and small outline  
packages allows the LMH6505 to be used in space-  
constrained applications.

DESCRIPTION

The LMH6505 is a wideband DC coupled voltage  
controlled gain stage followed by a high speed  
current feedback operational amplifier which can  
directly drive a low impedance load. The gain  
adjustment range is 80 dB for up to 10 MHz which is  
accomplished by varying the gain control input  
voltage, VG.

Figure 1. Gain vs. VG  
Maximum gain is set by external components, and  
the gain can be reduced all the way to cutoff. Power  
consumption is 110 mW with a speed of 150 MHz  
and a gain control bandwidth (BW) of 100 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 ±0.5 dB at maximum  
gain. Furthermore, gain is tested and ensured 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) ensured.
