Circuit Description
The LT6402-6 is a low noise, low distortion differential
amplier/ADC driver with:
–3dB bandwidth
DC to 300MHz
Fixed gain independent of RLOAD
2V/V (6dB)
Differential input impedance
200Ω
Low output impedance
Built-in, user adjustable output ltering
Requires minimal support circuitry
Referring to the block diagram, the LT6402-6 uses a
closed-loop topology which incorporates 3 internal am-
pliers. Two of the ampliers (A and B) are identical and
drive the differential outputs. The third amplier is used
to set the output common mode voltage. Gain and input
impedance are set by the 200Ω resistors in the internal
feedback network. Output impedance is low, determined
by the inherent output impedance of ampliers A and B,
and further reduced by internal feedback.
The LT6402-6 also includes built-in single-pole output
ltering. The user has the choice of using the unltered
outputs, the ltered outputs (75MHz –3dB lowpass), or
modifying the ltered outputs to alter frequency response
by adding additional components. Many lowpass and
bandpass lters are easily implemented with just one or
two additional components.
