Page 5: Overview
EVM components. EVM Operational Procedure The EVM provides a flexible means of evaluating the ADS5423/24/33 or ADS5411 in a number of modes of operation. A basic setup procedure that can be used as a board confidence check is as follows: 1. - Page 6 EVM Operational Procedure JUMPER FUNCTION SJP3 Provides AIN+ source to ADC device SJP4 Provides AIN– source to ADC device 2. Connect supplies to the EVM as follows: +5 V (4.75 V–5.25 V) ADC analog supply to J3 and return to J2. +3.3 V (3 V–3.6 V) digital buffer supply to J4 and J1 and return to J6 3.
