 DESCRIPTION
LTC2492/LTC2488/LTC2486 
2-/4-Channel 24-/16-Bit ΔΣ ADC 
with Easy Drive Input Current Cancellation
Demonstration circuit 1009A-A features the LTC
®
2492 
2-/4-channel, 24-bit ΔΣADC with Easy Drive™ inputs. 
Key DC specifications include 2ppm INL, 1ppm offset, 
25ppm full-scale error and 10nV/°C offset drift. In the 
6.8Hz/600nV
RMS
 mode, input normal mode rejection of 
50Hz and 60Hz noise is better than 87dB. The LTC2492 also 
includes an internal temperature sensor that is accurate 
to 2°C over the operating temperature range.
Demonstration circuit 1009A-B features the LTC2488 
2-/4-channel, 16-Bit ADC that is pinout and software 
compatible with the LTC2492.
Demonstration circuit 1009A-C features the LTC2486 
2-/4-channel 16-Bit ADC that also includes a PGA with 
a gain range from 1 to 256 and the same temperature 
sensor as the LTC2492.

BOARD PHOTO
DC1009 is a member of Linear Technology‘s QuikEval™ 
family of demonstration boards. It is designed to allow easy 
evaluation of the LTC2492, LTC2488 or LTC2486. DC1009 
may be connected directly to the target application’s ana-
log signals while using the DC590 USB serial controller 
board and supplied software to measure performance.  
After evaluating with LTC’s software, the digital signals can 
be connected to the application’s processor/controller for 
development of the serial interface.
