The ADS1208 is a 2nd-order ∆ Σ (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 rejec- tion.
