DESCRIPTION
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.
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.
