Texas Instruments  ADS1208IPW

The ADS1208 is a 2nd-order (delta-sigma) modulator 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.
