Full-featured evaluation board for the AMC1200 single-channel precision isolation amplifier
Screw terminals for easy access to analog inputs and outputs
Two package options included:
– AMC1200BDUB
– AMC1200BDWV
Optional isolated power to VDD1 from VDD2
Introduction
The AMC1200 is a precision isolation amplifier with an output separated from the input circuitry by a
silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified
to provide basic galvanic isolation of up to 4000 VPEAK according to UL1577 and IEC60747-5-2
specifications.
For use in high-resolution measurement applications, the input of the AMC1200 is optimized for direct
connection to shunt resistors or other low-level signal sources.
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with
the AMC1200EVM.
2
Analog Interface
There are two AMC1200 devices installed on the EVM. Both of the analog inputs to the AMC1200 are
routed from the two-wire screw terminals at J2 and J5. These screw terminals give the user access to the
inverting and noninverting inputs of the AMC1200 devices installed at U1 and U2.
2.1
Analog Inputs
The analog inputs to the AMC1200EVM printed circuit board (PCB) consists of simple RC filter circuits.
Connectors J2 and J4 have identical configurations. An example input circuit for the AMC1200 is shown in
Figure 1.

Power Supplies
The AMC1200 requires two separate power rails, VDD1 and VDD2. VDD1 is on the high voltage side of
the amplifier. VDD2 is on the user side of the amplifier.
3.1
VDD1 Input
J1 provides access to the to the VDD1 supply. For power provided from high-side isolated rails (such as
from a gate drive supply), move the shunt on jumper JP1 to cover pins 1 and 2. Use a voltage between
4.5 VDC and 5.5 VDC for the user-applied VDD1 supply. In the EVM default configuration, VDD1 is
provided from VDD2 by means of an isolation transformer and the SN6501 transformer driver. In the
default configuration, apply 5 V to VDD2 through J3. The input power is shown in Figure 3.

BOM, Schematic, and Layout
www.ti.com
An analog input signal may be applied directly at screw terminal J2 or J5. Refer to Figure 1 and Table 3
for details. The differential analog input range, (VIN+) – (VIN–), is specified at ±250 mV with a maximum
of ±320 mV before clipping occurs.
The analog outputs have a nominal gain of 8 through the AMC1200 isolation amplifiers. With an input
voltage of ±250 mV, the nominal output is therefore ±2.0 V. The output voltage is centered on VDD / 2 and
provides a convenient analog input range to the embedded analog-to-digital converters (ADCs) of the
MSP430 and TMS320C2000 series of digital processors.

EVALUATION BOARD/KIT/MODULE (EVM)
WARNINGS, RESTRICTIONS AND DISCLAIMERS
For Feasibility Evaluation Only, in Laboratory/Development Environments. Unless otherwise indicated, this EVM is not a finished
electrical equipment and not intended for consumer use. It is intended solely for use for preliminary feasibility evaluation in
laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application risks
associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a finished end
product.
Your Sole Responsibility and Risk. You acknowledge, represent and agree that:
1.
2.
3.
4.
You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug
Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees,
affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes.
You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable
regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates,
contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical)
between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to
minimize the risk of electrical shock hazard.
Since the EVM is not a completed product, it may not meet all applicable regulatory and safety compliance standards (such as UL,
CSA, VDE, CE, RoHS and WEEE) which may normally be associated with similar items. You assume full responsibility to determine
and/or assure compliance with any such standards and related certifications as may be applicable. You will employ reasonable
safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even if the EVM should fail to
perform as described or expected.
You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials.
Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the
user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and
environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact
a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the
specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or
interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the
load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures
greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include
but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the
EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please
be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable
in electronic measurement and diagnostics normally found in development environments should use these EVMs.
Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their representatives
harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in
connection with any use of the EVM that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims
arise under law of tort or contract or any other legal theory, and even if the EVM fails to perform as described or expected.
Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such
as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, such as devices
which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate
Assurance and Indemnity Agreement.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
