LMH6505介绍

FEATURES Near ideal input characteristics （i.e. low input bias current， low offset， low pin 3 resistance） enable the 2• VS = ±5V， TA = 25°C， RF = 1 kΩ， RG = 100Ω， RL = device to be easily configured as an inverting 100Ω， AV = AVMAX = 9.4 V/V， Typical Values amplifier as well. Unless Specified. To provide ease of use when working with a single • −3 dB BW 150 MHz supply， the VG range is set to be from 0V to +2V • Gain Control BW 100 MHz relative to the ground pin potential （pin 4）。 VG input • Adjustment Range （《10 MHz） 80 dB impedance is high in order to ease drive requirement. In single supply operation， the ground pin is tied to a • Gain Matching （Limit） ±0.50 dB “virtual” half supply. • Supply Voltage Range 7V to 12V The LMH6505’s gain control is linear in dB for a large • Slew Rate （Inverting） 1500 V/μs portion of the total gain control range from 0 dB down • Supply Current （No Load） 11 mA to −85 dB at 25°C， as shown below. This makes the • Linear Output Current ±60 mA device suitable for AGC applications. For linear gain control applications， see the LMH6503 datasheet. • Output Voltage Swing ±2.4V The LMH6505 is available in either the 8-Pin SOIC or • Input Noise Voltage 4.4 nV/√Hz the 8-Pin VSSOP package. The combination of • Input Noise Current 2.6 pA/√Hz minimal external components and small outline • THD （20 MHz， RL = 100Ω， VO = 2 VPP） −45 dBc packages allows the LMH6505 to be used in spaceconstrained applications. APPLICATIONS • Variable Attenuator • AGC • Voltage Controlled Filter • Video Imaging Processing
