The LT6552 is a video difference amplifier with two pairs

of high impedance inputs. The primary purpose of the

LT6552 is to convert high frequency differential signals

into a single-ended output, while rejecting any common

mode noise. In the simplest configuration, one pair of

inputs is connected to the incoming differential signal,

while the other pair of inputs is used to set amplifier gain

and DC level. The device will operate on either single or

dual supplies and has an input common mode range

which includes the negative supply. The common mode

rejection ratio is greater than 60dB at 10MHz. Feedback is

applied to Pin 8 and the LT6552’s transient response is

optimized for gains of 2 or greater.

Figure 3 shows the single supply connection. The ampli-

fier gain is set by a feedback network from the output to

Pin 8 (FB). A DC signal applied to Pin 1 (REF) establishes

the output quiescent voltage and the differential signal is

applied to Pins 2 and 3.

Figure 4 shows several other connections using dual

supplies. In each case, the amplifier gain is set by a

feedback network from the output to Pin 8 (FB).
