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.
