... The shutdown feature reduces power dissipa- tion to less than 1mW and allows multiple amplifiers to drive the same cable. The LT6552 is available in the 8-lead SO package as well as a tiny, dual fine pitch leadless package (DFN). The device is specified over the commercial and industrial temperature ranges ...

... U U APPLICATIO S I FOR ATIO 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 ...

... U U APPLICATIO S I FOR ATIO Amplifier Characteristics Figure 5 shows a simplified schematic of the LT6552. There are two input stages; the first one consists of transistors for the (+) and (–) inputs while the second input stage consists of transistors Q9 to Q16 for the reference and feedback inputs. This topology provides high slew rates at low supply voltages ...

... Figure 6 shows the closed-loop gain of 2 frequency response with various values of the feedback capacitor. This peaking shows time domain overshoot of 40%; with an 8pF feedback capacitor the overshoot is eliminated. Figures 7A and 7B show the Small Signal Response of the LT6552 with and without an 8pF feedback capacitor ...
