LMH6503

Wideband, Low Power, Linear Variable Gain Amplifier

General Description

Features

™

The LMH 6503 is a wideband DC coupled differential input

V_S

5V, T_A= 25˚C, R_F= 1kΩ, R_G= 174Ω, R_L= 100Ω, A_V

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.

= A_V(MAX)= 10, Typical values unless specified.

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_Gis

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.
