DESCRIPTION

•
Six Pseudo- or Four Fully Differential Inputs  
The ADS7865 is  
a
dual, 12-bit, 2MSPS  
analog-to-digital converter (ADC) with four fully  
differential or six pseudo-differential input channels  
grouped into two pairs for high-speed, simultaneous  
signal acquisition. Inputs to the sample-and-hold  
(S/H) amplifiers are fully differential and are  
maintained differentially to the input of the ADC. This  
architecture provides excellent common-mode  
rejection of 72dB at 100kHz, which is a critical  
performance characteristic in noisy environments.

SNR: 71.7dB, THD: –87dB

•
Flexible Power-Down Features  
Variable Power-Supply Ranges: 2.7V to 5.5V  
Low-Power Operation: 44mW Maximum at 5V  
Operating Temperature Range:  
–40°C to +125°C  
The ADS7865 is pin-compatible with the ADS7862,  
but offers additional features such as  
a
•
Pin-Compatible Upgrade for the ADS7862  
programmable channel sequencer and reference  
output, flexible supply voltage (2.7V to 5.5V for AVDD  
and BVDD), a pseudo-differential input multiplexer with  
three channels per ADC, and several power-down  
features.  
APPLICATIONS  
•

•
Motor Control  
Multi-Axis Positioning Systems  
Three-Phase Power Control  
The ADS7865 is offered in a TQFP-32 package. It is  
specified over the extended operating temperature  
range of –40°C to +125°C.
