This easy-to-use device includes a sample-andhold, a precision reference, a switched capacitor successive approximation A/D and trimmed internal clock.
The input range is specified for bipolar inputs of ±10V, ±5V and ±3.
3V and unipolar inputs of 0V to 10V, 0V to 5V and 0V to 4V.
Maximum DC specs include ±2LSB INL and 16-bit no missing codes over temperature.
It has a typical signal-to-noise ratio of 87dB.
The ADC has a high speed serial interface.
The serial output data can be clocked out using either the internal serial shift clock or be clocked out by an external shift clock.
A separate convert start input (R/C) and a data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
