GENERAL DESCRIPTION
The AD15700 is a precision component to interface analog input and output channels to a digital processor. It is ideal for area limited applications that require maximum circuit density. The AD15700 contains the functionality of a 16-bit, 1 MSPS charge redistribution SAR analog-to-digital converter that operates from a 5 V power supply. The high speed 16-bit sampling ADC incorporates a resistor input scaler that allows various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports. The AD15700 also contains a 14-bit, serial input, voltage output DAC that operates from a 5 V supply and has a settling time of 1 ms.
