DESCRIPTION
The ADS5409 is a high linearity dual channel 12-bit, 900 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
outstanding spurious-free dynamic range over a large input-frequency range. The device is available in a 196pin
BGA package and is specified over the full industrial temperature range (–40°C to 85°C).
