Page 10: Overview
Chapter 1 Overview The ADS1110EVM is an evaluation fixture for the ADS1110 16-bit delta-sigma ∆ ∑ ) analog-to-digital converter (ADC). Designed for prototyping and evaluation, it includes four ADS1110 devices, each with a different I C address. Topic Page Introduction . -
Page 11: Introduction
The ADS1110EVM is designed using a simple card format developed by TI. This simple, consistent design makes the ADS1110EVM very easy to connect to your own prototype system. You can even think of the ADS1110EVM as an alternate package for the ADS1110one much larger than the device itself, but also much easier to wire up by hand on your test bench. -
