The Simple Way to Match to a High-Speed ADC Input - LTM9001

Todd Nelson - Mixed Signal Applications Engineering Manager Jun 15th 2009

High-speed, high-resolution ADCs are critical components in communications and instrumentation applications. The interface between the final amplifier of the signal chain and the input pins of the ADC is challenging and time-consuming. Yet it is critical to the performance of the entire system. Traditionally, this requires impedance matching, developing an anti-alias filter and multiple iterations of the board layout to get everything right. Linear Technology’s LTM9001 greatly simplifies this part of the signal chain design. The ADC, the amplifier, all of the bypass capacitors and especially the matching and filter network are all integrated.
