GENERAL DESCRIPTION
The AD8401 is a complete data acquisition and control system containing ADC, DAC, 4-channel MUX, and internal voltage reference. Built using CBCMOS, this monolithic circuit offers the user a complete system with very high package density and reliability.
The converter is a successive approximation ADC with T/H, and is capable of operating with conversion times as short as 2 µs. Analog input bandwidth is 200 kHz, and DAC output voltage settling time is less than 4 µs, making the AD8401 capable of controlling servo loops with speed and precision.
