LMH6504

Wideband, Low Power, Variable Gain Amplifier

General Description

The LMH

trolled gain stage followed by a high-speed current feedback

Op Amp which can directly drive a low impedance load. Gain

adjustment range is 80 dB for up to 10 MHz by varying the

gain control input voltage, V

Maximum gain is set by external components, and the gain

can be reduced all the way to cut-off. Power consumption is

110 mW with a speed of 150 MHz and a gain control band-

width (BW) of 150 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

mum gain. Furthermore, gain is tested and guaranteed over

a wide range. The output current feedback Op Amp allows

high frequency large signals (Slew Rate

can also drive a heavy load current (60 mA). Near ideal input

characteristics (i.e. low input bias current, low offset, low pin

3 resistance) enable the device to be easily configured as an

inverting amplifier as well (see Application Information sec-

tion for details).

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

pin potential (pin 4). V

ease drive requirement. In single supply operation, the

ground pin is tied to a "virtual" half supply.

LMH6504 gain control is linear in dB for a large portion of the

total gain control range. This makes the device suitable for

AGC applications. For linear gain control applications, see

LMH6503 data sheet.

The combination of minimal external components and small

outline packages (SO8 and MSOP8) allows the LMH6504 to

be used in space-constrained applications.
