DEMO MANUAL DC1011A

Description

LTC2498, LTC2496, LTC2494

24-bit/16-bit, 8-/16-Channel, Easy Drive

ΔS ADC with SPI Interface

Demonstration Circuit 1011A-A features the LT C

2498

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 6.9Hz/280nV

RMS

mode, input normal mode rejection

of 50Hz and 60Hz noise is better than 87dB.

DC1011A-B features the LTC2496 16-bit Δ∑ ADC that is

pinout and software compatible with the LTC2498.

DC1011A-C features the LTC2494 16-bit Δ∑ ADC with

internal PGA and temperature sensor.

DC1011A is a member of Linear Technology’s QuikEval™

family of demonstration boards. It is designed to allow

easy evaluation of the LTC2498, LTC2496 or LTC2494

and may be connected directly to the target application’s

analog signals while using the DC590 USB Serial Control-

ler board and QuikEval software to measure performance.

The exposed ground planes allow proper grounding to

prototype circuitry. After evaluating with LT C ’s software,

the digital signals can be connected to the application’s

processor/controller for development of the serial interface.
