This user's guide describes the characteristics, operation, and use of the ADS8638EVM, both by itself and
as a part of the ADS8638EVM-PDK. This evaluation module (EVM) is designed to feature the ADS8638
but can also support the ADS8614, ADS8618, or
either an 8- or 12-bit, 1-MHz, multi-channel, successive approximation register (SAR) analog-to-digital
converters (ADCs). The EVM allows evaluation of all aspects of the ADS8638 device. A complete circuit
description as well as schematic diagram and bill of materials are included.

Page 3: Evm Overview
EVM and the term evaluation module are synonymous with the ADS8638EVM. For clarity of reading, the rest of this manual will refer only to the ADS8638EVM or ADS8638EVM-PDK, but operation of the EVM and kit for the ADS8614, ADS8618, and ADS8634 is identical, unless otherwise noted. -
Page 4: Analog Interface
Analog Interface For maximum flexibility, the ADS8638EVM is designed for easy interfacing to multiple analog sources. Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin, dual row header/socket combination at J1. This header/socket provides access to the analog input pins of the ADC. -

EVM Operation www.ti.com Digital Control The digital control signals can be applied directly to J2 (top or bottom side). The modular ADS8638EVM can also be connected directly to a DSP or microcontroller interface board, such as the 5-6K Interface HPA-MCU Interface boards available from Texas Instruments, or the MMB0 if purchased as part of the ADS8638EVM-PDK. -

Page 10: Connecting Ads8638Evm To Mmb0
The MMB0 is a Modular EVM System motherboard. It is designed around the TMS320VC5507, a DSP with an onboard USB interface from Texas Instruments. The MMB0 also has 16 MB of SDRAM installed. The MMB0 is not sold as a DSP development board, and it is not available separately. TI cannot offer support for the MMB0 except as part of an EVM kit. -
Page 11: Connecting The Power Supply
Connecting the Power Supply The ADS8638EVM-PDK requires multiple supplies to power the ADC to be used with the MMB0 motherboard. The ADS8638 requires two high-voltage supplies (±10 V to ±15 V), HVDD and HVEE, along with a +5-V supply to power the analog, AVDD, and +3.3 V to +5 V to power the digital circuitry, DVDD. -
Page 12: Ni-Visa Driver Installation
The program for evaluating the ADS8638EVM-PDK is called ADCPro. This program uses plug-ins to communicate with the EVM. The ADS8638EVM-PDK plug-in is included in the ADS8638EVM-PDK package. -
