THS4513-SP
SLOS539A – SEPTEMBER 2007 – REVISED OCTOBER 2007
The 225 Ω resistors and 2.7 pF capacitor between
the THS4513 outputs and ADS5424 inputs (along
with the input capacitance of the ADC) limit the
bandwidth of the signal to about 100 MHz (–3 dB).
Because the ADS5424s recommended input
common-mode voltage is 2.4 V, the THS4513 is
operated from a single power supply input with V_S+ =
5 V and V_S– = 0 V (ground).
