BUF634AD Evaluation module
The BUF634ADEVM is an evaluation module (EVM) for the BUF634A high-speed buffer in the D (8-pin
SOIC) package. The BUF634ADEVM features two BUF634A devices and is designed to quickly
demonstrate the functionality and versatility of the buffer. Optionally, the buffers can be configured as
outputs for a dual SOIC amplifier in a composite loop. The EVM is ready to connect to power, signal
sources, and test instruments by using onboard connectors. The default configuration uses split supplies
and subminiature version A (SMA) input and output connecters with a 50-Ω output impedance for standard
test equipment. The EVM can be easily configured for other connections and single-supply operation.
Dual-channel path configuration is also available for the RCA™ audio input jacks and a 3.5-mm output
jack.
Throughout this document, the terms EVM and evaluation module are synonymous with the
BUF634ADEVM.

Power Connections
The BUF634ADEVM is equipped with banana jacks for easy connection of power. The positive supply
input is labeled V+, the negative supply input is labeled V–, and ground is labeled GND.
1.1.1
Split-Supply Operation
To operate in split supply, apply the positive supply voltage to V+, the negative supply voltage to V–, and
the ground reference from supply to GND.
1.1.2
Single-Supply Operation
To operate in single supply, apply jumper V– to GND and apply the positive supply voltage to V+. Inputs
and outputs must be biased per data sheet specifications for proper operation.
1.2
Input and Output Connections
The BUF634ADEVM is equipped with SMA connectors for easy connection to benchtop signal generators
and analysis equipment. Additionally, the EVM also includes RCA input jacks and a 3.5-mm output jack
that can be used with the two BUF634A devices in a differential audio buffer configuration. The
connections to the SMA outputs include 50–Ω termination resistors for easy connection to 50–Ω
impedance test equipment. The inputs are high impedance but can be easily terminated to 50 Ω as well by
populating resistors R1 and R4. For best results in the default configuration, route the outputs to test
equipment using cables with a 50–Ω characteristic impedance and the connect the inputs to the signal
source with as short of cables as possible.
1.2.1
Use With a Dual SOIC Amplifier in a Composite Loop
The BUF634ADEVM features the option to configure the devices in two composite amplifier loops using a
dual SOIC package amplifier, such as the OPA2810. In the composite loop, the BUF634A forms an output
driving stage for the chosen input amplifier and, with the dual paths on the EVM, forms a differential
composite amplifier useful for applications such as audio amplification. When configuring the EVM to use
the composite loop, populate device U1, resistors R2, R3, R4, and R5, and capacitors C2, and C4, and
remove resistors R11 and R16.

EVM Use Restrictions and Warnings:
4.1 EVMS ARE NOT FOR USE IN FUNCTIONAL SAFETY AND/OR SAFETY CRITICAL EVALUATIONS, INCLUDING BUT NOT
LIMITED TO EVALUATIONS OF LIFE SUPPORT APPLICATIONS.
4.2 User must read and apply the user guide and other available documentation provided by TI regarding the EVM prior to handling
or using the EVM, including without limitation any warning or restriction notices. The notices contain important safety information
related to, for example, temperatures and voltages.
4.3 Safety-Related Warnings and Restrictions:
4.3.1
User shall operate the EVM within TI’s recommended specifications and environmental considerations stated in the user
guide, other available documentation provided by TI, and any other applicable requirements and employ reasonable and
customary safeguards. Exceeding the specified performance ratings and specifications (including but not limited to input
and output voltage, current, power, and environmental ranges) for the EVM may cause personal injury or death, or
property damage. If there are questions concerning performance ratings and specifications, User should 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 also result in unintended and/or inaccurate operation and/or possible
permanent damage to the EVM and/or interface electronics. Please consult the EVM user 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, even with the inputs and outputs kept within the specified allowable ranges, some circuit
components may have elevated case temperatures. These components include but are not limited to linear regulators,
switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the
information in the associated documentation. When working with the EVM, please be aware that the EVM may become
very warm.
4.3.2
EVMs 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 assumes all responsibility and liability for proper and safe handling and use of the EVM by User or its employees,
affiliates, contractors or designees. User assumes all responsibility and liability to ensure 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. User assumes all responsibility and
liability for any improper or unsafe handling or use of the EVM by User or its employees, affiliates, contractors or
designees.
4.4 User assumes all responsibility and liability to determine whether the EVM is subject to any applicable international, federal,
state, or local laws and regulations related to User’s handling and use of the EVM and, if applicable, User assumes all
responsibility and liability for compliance in all respects with such laws and regulations. User assumes all responsibility and
liability for proper disposal and recycling of the EVM consistent with all applicable international, federal, state, and local
requirements.
