ADS7864  
SBAS141ASEPTEMBER 2000REVISED MARCH 2005  
500kHz, 12-Bit, 6-Channel Simultaneous Sampling  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
6 Simultaneous Sampling Channels  
Fully Differential Inputs  
2µs Total Throughput per Channel  
No Missing Codes  
The ADS7864 is  
a
dual 12-bit, 500kHz  
analog-to-digital (A/D) converter with 6 fully differen-  
tial input channels grouped into three pairs for high  
speed simultaneous signal acquisition. Inputs to the  
sample-and-hold amplifiers are fully differential and  
are maintained differential to the input of the A/D  
converter. This provides excellent common-mode re-  
jection of 80dB at 50kHz which is important in high  
noise environments.  
Parallel Interface  
1MHz Effective Sampling Rate  
Low Power: 50mW  
6X FIFO  
The ADS7864 offers a parallel interface and control  
inputs to minimize software overhead. The output  
data for each channel is available as a 16-bit word  
(address and data). The ADS7864 is offered in a  
TQFP-48 package and is fully specified over the  
–40°C to +85°C operating range.
