This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION CONTINUED
The AFE5808A also integrates a low power passive mixer and a low noise summing amplifier to accomplish on-
chip CWD beamformer. 16 selectable phase-delays can be applied to each analog input signal. Meanwhile a
unique 3rd and 5th order harmonic suppression filter is implemented to enhance CW sensitivity.
The AFE5808A is available in a 15mm × 9mm, 135-pin BGA package and it is specified for operation from 0°C to
85°C. It is also pin-to-pin compatible to the AFE5807, AFE5803, and AFE5808.
