1 EVM Overview 1.1 Features User's Guide SLAU189 – September 2006 ADS8364/65MEVM This user's guide describes the characteristics, operation, and use of the ADS8364/65MEVM 16-bit, parallel analog-to-digital converter evaluation module (EVM).
www.ti.com 2 Introduction 3 Analog Interface 3.1 Analog Input – Channel A0 Introduction The ADS8364 and ADS8365 are high-speed, low-power, 6-channel, 16-bit A/D converters that operate from independent +5-V Avdd and Dvdd supplies. Internal buffer circuits powered from 3.
www.ti.com 3.2 Bipolar Input to Channel A0 Analog Interface NOTE: Components marked NI are NOT INSTALLED. Figure 1. Channel A0 Input Circuit This configuration allows single-ended signals of ± 2.5 V (+5 Vpp) to be applied to either input of channel A0 (J2 pin 1 or 3 referenced to pin 2).
www.ti.com 3.3 Analog Input – Channel A1 3.4 Analog Inputs –Channels B0/B1 and C0/C1 4 Digital Interface Digital Interface The output from the buffer stage in each case applies 0-5 V to the CHA0(+) input when the applied signal is connected to J2 pin 1 or J4 pin 2.
