DESCRIPTION  
The ADS2806 is a dual, high-speed, high dynamic range,  
12-bit pipelined Analog-to-Digital Converter (ADC). This con-  
verter includes a high-bandwidth track-and-hold that gives  
excellent spurious performance up to and beyond the Nyquist  
rate. The differential nature of this track-and-hold and ADC  
circuitry minimizes even-order harmonics and gives excel-  
lent common-mode noise immunity. The track-and-hold can  
also be operated single-ended.  
The ADS2806 provides an over-range indicator flag to  
indicate an input signal that exceeds the full-scale input  
range of the converter. This flag can be used to reduce the  
gain of front end gain control circuitry. There is also an  
output enable pin to allow for multiplexing and testability on  
a PC board.  
The ADS2806 employs digital error correction techniques to  
provide excellent differential linearity for demanding imag-  
ing applications. The ADS2806 is available in a TQFP-64  
power package.  
The ADS2806 provides for setting the full-scale range of the  
converter without any external reference circuitry. The internal
