AD8401 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 ms. Analog input bandwidth is 200 kHz, and DAC output voltage settling time is less than 4 ms, making the AD8401 capable of controlling servo loops with speed and precision.
The 8-bit data interface provides both read and write operation for parallel bus interfaces to microcontrollers and DSP processors. An external 5 MHz clock sets the 2 ms conversion rate. Slower clocks reduce the conversion time and the internal power dissipation. The standard control lines: Reset, Busy, Interrupt, Read and Write complete the handshaking signals for microprocessor communication. A start trigger ST input allows precise sampling intervals in synchronous sampling applications. The input multiplexer addressing is designed for direct interface to the AD899 hard-disk drive, read-channel device with no extra hardware or special software. Analog input range levels are likewise compatible with the AD899.
The AD8401 is designed to operate from a single +5 volt supply, which will give an ADC input range of 0 V to 3.0 V, and DAC output range of 0 V to 2.5 V.
The AD8401 is offered in the SOIC-28 surface mount package, and is guaranteed to operate over the extended industrial temperature range of 40 to +85.
