PRODUCTION DATA.
For optimum performance, the analog inputs must be driven differentially. If the inputs are driven in a single-ended manner, capacitors must be placed on the INx_M signals and close to the INx_M pins. An optional 5-Ω to 15-Ω resistor in series with each input pin can be kept to damp out ringing caused by package parasitics. The drive circuit may have to be designed to minimize the impact of kick-back noise generated by sampling switches opening and closing inside the ADC, as well as ensuring low insertion loss over the desired frequency range and matched impedance to the source.
