Preliminary data sheet
11.3.4 Biasing
11.4.1 Drive modes
11.4 Clock input
The common-mode input voltage (V
buffer bias current can be set to one of three levels (high, medium or low) via the SPI (see
Table
The ADC1415S can be driven differentially (SINE, LVPECL or LVDS) with little or no
degradation on dynamic performances. It can also be driven by a single-ended LVCMOS
signal connected to pin CLKP (CLKM should be connected to ground via a capacitor) or
CLKM (CLKP should be connected to ground via a capacitor).
