2.2.3.1 Power Configuration
The default configuration of the AFE882H1EVM allows the board to be powered from the USB while using an
external source for the ±15-V supplies. Jumper J26 connects power from the 3p3V line to the PVDD pins of
the device, and jumper J27 connects power to the IOVDD pins of the device. To use external power supplies,
remove the jumpers in J26 and J27 and connect the supplies to banana jacks J22 and J24 for connections to
PVDD and IOVDD.
2.2.3.2 External SPI and UART Controllers
To use an external SPI or UART controller with the EVM board, disconnect the connections from the FTDI
controller to the devices at the level shifters. To disable the level shifters, use the J25 header and add jumpers
from SPI_EN, UART_EN, and RESET_EN to ground. After the level shifters are disabled, connect an external
controller to pin headers at J9, J15, and J16 to control the AFE882H1 and XTR305.

Figure 3-1. Block Diagram for the AFE882H1EVM
With the default jumper settings, the USB sources a 3.3-V supply for PVDD and a 1.8-V supply for IOVDD. The
PVDD and IOVDD supplies source power through J26 and J27, respectively. To use external supplies, remove
the shunts connecting the jumpers and use the banana jack connectors at J22 for PVDD and J24 for IOVDD.
The output of the AFE882H1 sets the input voltage of an XTR305 current or voltage output driver. The XTR305
requires ±15-V supplies that are applied to banana jack connectors J7 and J8. With the resistor settings of the
XTR305, the output can be set to a voltage range of ±11 V or a current range of –25-mA to +25-mA. Access the
AFE882H1 output and XTR305 output at SMA connectors J11 and J12, respectively.
SMA connector J14 is coupled to the HART input of the AFE882H1. Jumpers at J4 and J6 determine if the
HART signal is capacitively coupled to the device, or if the HART signal connects to the device through an
external filter. Access the HART output at SMA connector J18. SMA connectors J10 and J13 connect to the
inputs of a 16-bit ADC on the AFE882H1, and SMA connector J17 connects to the device CLK_OUT output
clock.

STANDARD TERMS FOR EVALUATION MODULES
1. Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or
documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance
with the terms set forth herein. User's acceptance of the EVM is expressly subject to the following terms.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.
2Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License
Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)
business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.
2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit
User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty
period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or
replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be
warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
WARNING
Evaluation Kits are intended solely for use by technically qualified,
professional electronics experts who are familiar with the dangers
and application risks associated with handling electrical mechanical
components, systems, and subsystems.
User shall operate the Evaluation Kit within TI’s recommended
guidelines and any applicable legal or environmental requirements
as well as reasonable and customary safeguards. Failure to set up
and/or operate the Evaluation Kit within TI’s recommended
guidelines may result in personal injury or death or property
damage. Proper set up entails following TI’s instructions for
electrical ratings of interface circuits such as input, output and
electrical loads.
NOTE:
EXPOSURE TO ELECTROSTATIC DISCHARGE (ESD) MAY CAUSE DEGREDATION OR FAILURE OF THE EVALUATION
KIT; TI RECOMMENDS STORAGE OF THE EVALUATION KIT IN A PROTECTIVE ESD BAG.
