7V to 5.
5V Digital Supply Pin APPLICATIONS • Motor Control • Current Measurement • Hall Sensors • Bridge Sensors • Instrumentation DESCRIPTION The ADS1208 is a 2nd-order ∆Σ (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.
