... S I FOR ATIO Logic Inputs The logic inputs of the LT1204 are compatible with all 5V logic. All pins have ESD protection (> 2kV), and shorting them to 12V or 15V will cause excessive currents to flow. Limit the current to less than 50mA when driving the logic above 6V ...

... For gains less than 10, the overall slew rate is limited by the input stage. The input slew rate of the LT1204 is approximately 135V/ s and is set by internal currents and capacitances. The output slew rate is set by the value of the feedback resistors and the internal capacitances ...

... The key to the outstanding crosstalk performance of the LT1204 is the use of tee switches (see Figure 1). When the tee switch is on (Q2 off) Q1 and Q3 are a pair of emitter followers with excellent AC response for driving the CFA. 1204AI05 ...

... AI13 A shutdown feature (Pin 12 low) reduces the supply current to 1.5mA and lowers the power dissipation when the LT1204 is not in use. If the part is shut down, the bootstrapping is inoperative and the feedback resis- tors will load the output. If the CFA is operated at a gain ...

... As a practical matter the gain error at frequency is also set by capacitive loading. The disabled output capaci- tance of the LT1204 is about 8pF, and in the case of sixteen LT1204s, it would represent a 128pF load. The combination of 1.67k and 128pF correspond to about a 0.3dB roll-off at 5MHz. ...

... CABLE *OPTIONAL 0.5, 0.25 and 0.125 to form an amplifier with a gain of 16 when LT1204 #1 is selected. LT1204 #2 is connected to the same attenuator. When enabled (LT1204 #1 disabled), it results in gain of 1, 0.5, 0.25 and 0.125. The wide input common mode range of the LT1204 is needed to accept inputs of 8V ...

... The circuit uses an LT1227 current feedback amplifier connected with a gain of – 2, and an LT1204 with a gain of 2. The 47 resistors back-terminate the low cost cable in its charac- teristic impedance to prevent reflections. The receiver for the differential signal is an LT1193 connected for a gain of 2 ...
