DESCRIPTION
LTC2499/LTC2497/LTC2495
24-/16-Bit Easy Drive
8-/16- Channel Delta Sigma
ADC with I
2
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
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
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.
