DESCRIPTION
The ADS1208 is a 2nd-order DS (delta-sigma) modu·
lator operating at a 10MHz clock rate. The specified
input range is ±100mV, optimized for current
measurement with a Hall sensor, especially in motor
control applications. The ADS1208 contains a
programmable current source for sensor biasing and
has integrated input buffers for fast settling of the
sample capacitors; it also requires only a minimum of
external components. The differential analog input
offers low noise and excellent common-mode rejection.
