Check for Samples: LMH6504 FEATURES DESCRIPTION The LMHв„ў6504 is a wideband DC coupled 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 80 dB
for up to 10 MHz by varying the gain control input
voltage, VG. 1 23 VS = ±5V, TA = 25°C, RF = 1 KΩ, RG = 100Ω, RL
= 100Ω, AV = AVMAX = 9.7V/V, Typical values
unless specified.
-3 dB BW 150 MHz
Gain control BW 150 MHz
Adjustment range ( 1500 V/Ојs) and
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 section for details). Variable attenuator
