Dual 500kHz, 12-Bit, 2 + 2 Channel  
Simultaneous Sampling  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
The ADS7862 is a dual 12-bit, 500kHz analog-to-  
digital converter (A/D) with 4 fully differential input  
channels grouped into two pairs for high speed simulta-  
neous signal acquisition. Inputs to the sample-and-hold  
amplifiers are fully differential and are maintained dif-  
ferential to the input of the A/D converter. This provides  
excellent common-mode rejection of 80dB at 50kHz  
which is important in high noise environments.  
4 INPUT CHANNELS  
FULLY DIFFERENTIAL INPUTS  
2µs TOTAL THROUGHPUT PER CHANNEL  
GUARANTEED NO MISSING CODES  
PARALLEL INTERFACE  
1MHz EFFECTIVE SAMPLING RATE  
LOW POWER: 40mW  
The ADS7862 offers parallel interface and control in-  
puts to minimize software overhead. The output data for  
each channel is available as a 12-bit word. The ADS7862  
is offered in an TQFP-32 package and is full specified  
over the –40°C to +85°C operating range.
