DESCRIPTION

LTC2499/LTC2497/LTC2495

24-/16-Bit Easy Drive

8-/16- Channel Delta Sigma

ADC with I

C Interface

Demonstration circuit 1012A-A features the

8-/16-channel, 24-bit delta sigma ADC 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 LTC2499

also includes an internal temperature sensor that is accurate

to 2°C over the operating temperature range.
DC1012A-B features the LTC2497 16-bit

∆Σ ADC that is

pinout and software compatible with the LTC2499.
DC1012A-C features the LTC2495 16-bit

∆Σ ADC that also

includes a PGA with a gain range from 1 to 256 and the

same temperature sensor as the LTC2499.

DC1012A is a member of Linear Technology’s QuikEval™

family of demonstration boards. It is designed to allow

easy evaluation of the LTC2499, LTC2497 or LTC2495.

DC1012A may be connected directly to the target ap-

plication’s analog signals while using the DC590 USB

serial controller board and QuikEval software to measure

performance. The exposed ground planes allow proper

grounding to prototype circuitry. After evaluating with

LTC’s software, the digital signals can be connected to

the application’s processor/controller for development

of the serial interface.
