ADS1208 - 10MHz Modulator With Built-in Current Excitation for Hall Sensors
Updated : 2020-01-09 14:26:06Description
The ADS1208 is a 2nd-order  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 <b><b>ADS1208</b></b> 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.</p> Products containing the "ADS1208")
