FEATURES  
DESCRIPTION  
The LMH™6502 is  
a
wideband DC coupled  
23  
•
VS = ±5V, TA = 25°C, RF = 1kΩ, RG = 174Ω, RL =  
100Ω, AV = AV(MAX) = 10 Typical Values Unless  
Specified.  
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.  
•
-3dB BW: 130MHz

•
Gain Control BW: 100MHz  
Maximum gain is set by external components and the  
gain can be reduced all the way to cut-off. Power  
consumption is 300mW with a speed of 130MHz.  
Output referred DC offset voltage is less than 350mV  
over the entire gain control voltage range. Device-to-  
device Gain matching is within ±0.6dB 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 (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.  
Adjustment Range (Typical Over Temp): 70dB  
Gain Matching (Limit): ±0.6dB  
Slew Rate: 1800V/µs  
Supply Current (No Load): 27mA  
Linear Output Current: ±75mA  
Output Voltage (RL = 100Ω): ±3.2V  
Input Voltage Noise: 7.7nV/√Hz  
Input Current Noise: 2.4pA/√Hz  
THD (20MHz, RL = 100Ω, VO = 2VPP): −53dBc  
Replacement for CLC520  
APPLICATIONS  
•

•
•
Variable Attenuator  
AGC  
To provide ease of use when working with a single  
supply, VG range is set to be from 0V to +2V relative  
to pin 11 potential (ground pin). In single supply  
operation, this ground pin is tied to a "virtual" half  
supply.  
Voltage Controller Filter  
Video Imaging Processing  
LMH6502 gain control is linear in dB for a large  
portion of the total gain control range. This makes the  
device suitable for AGC circuits among other  
applications. For linear gain control applications, see  
the LMH6503 datasheet. The LMH6502 is available in  
the SOIC and TSSOP package.
