www.ti.com SNOSB06A – JANUARY 2008 – REVISED MARCH 2013 LMH6514 600 MHz, Digital Controlled, Variable Gain Amplifier
Check for Samples: LMH6514 FEATURES DESCRIPTION The LMH6514 is a high performance, digitally
controlled variable gain amplifier (DVGA). It combines
precision gain control with a low noise, ultra-linear,
differential amplifier. Typically, the LMH6514 drives a
high performance ADC in a broad range of mixed
signal and digital communication applications such as
mobile radio and cellular base stations where
automatic gain control (AGC) is required to increase
system dynamic range. When used in conjunction
with a high speed ADC, system dynamic range can
be extended by up to 42 dB. 1 2 Adjustable Gain with a 42 dB Range
Precise 6.02 dB Gain Steps
Parallel 3 Bit Gain Control
On Chip Register Gain Setting
Fully Differential Signal Path
Single Ended to Differential Capable
200Ω Input Impedance
Small Footprint (4 mm x 4 mm) WQFN Package APPLICATIONS The LMH6514 has a differential input and output
allowing large signal swings on a single 5V supply. It
is designed to accept signals from RF elements and
maintain a terminated impedance environment. The …
