FEATURES  
DESCRIPTION  
The LMH™6503 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 135MHz

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 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 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) ±0.7dB  
Slew Rate 1800V/µs  
Supply Current (No Load) 37mA  
Linear Output Current ±75mA  
Output Voltage (RL = 100Ω) ±3.2V  
Input Voltage Noise 6.6nV/√Hz  
Input Current Noise 2.4pA/√Hz  
THD (20MHz, RL = 100Ω, VO = 2VPP) −57dBc  
Replacement for CLC522  
APPLICATIONS  
•

•
•
Variable Attenuator  
AGC  
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.  
Voltage Controller Filter  
Multiplier  
The LMH6503 is available in the SOIC-14 and  
TSSOP-14 package.
