LMH6502

Wideband, Low Power, Linear-in-dB Variable Gain

Amplifier

General Description

Features

™

The LMH 6502 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.

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 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.

Applications

n Variable attenuator

n AGC

n Voltage controller filter

n Video imaging processing

To provide ease of use when working with a single supply,

V_Grange 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.

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 con-

trol applications, see the LMH6503 datasheet. The

LMH6502 is available in the SOIC-14 and TSSOP-14 pack-

age.
