The TI-10SAR01/1M is a 10-bit successive approximation analog-to-digital converter (SAR ADC) with differential analog inputs and parallel output drivers. Its typical conversion rate is 1.5 MSPS. Its fully differential architecture provides good common-mode noise rejection and effectively suppresses internal and external noise sources. Implemented digital-to-analog converter (DAC) uses binary weighted capacitor architecture with two segmented arrays allowing to decrease the total input capacitance. Input bootstrap switches provide high linearity and low on-resistance at broad ranges of supplies and operating temperatures. Internal current source with several current modes may be used to set the desired speed/power consumption ratio of the ADC: lower bias currents may be used for lower conversion frequencies.
