DESCRIPTION

The ADS5402 is a high linearity dual channel 12-bit, 800 Msps analog-to-digital converter (ADC) easing front end

filter design for wide bandwidth receivers. The analog input buffer isolates the internal switching of the on-chip

track-and-hold from disturbing the signal source as well as providing a high-impedance input. Optionally the

output data can be decimated by two. Designed for high SFDR, the ADC has low-noise performance and very

good spurious-free dynamic range over a large input-frequency range. The device is available in a 196-pin BGA

package and is specified over the full industrial temperature range (–40°C to 85°C).
