TMUX4827YBH Evaluation Module
Description
The TMUX4827YBHEVM is used to evaluate the
performance of the TMU4827. The evaluation module
(EVM) comes with a TMUX4827YBH device soldered
on. The EVM allows for an easy way for engineers
to evaluate the TMUX4827 with audio signals by
using on board audio jacks. Additionally, test points
on board are provided to allow for the capability to test
for signals that aren't audio signals as well.
Features
• TMUX4827YBH pre-soldered on board
• 2 power supply decoupling capacitor from VDD to
Ground (1µF 0402; 0.1µF 0402)
• 6 test points on I/O's supporting TMUX4827 full
current capabilities
• 7 additional GND test points for easy of probing
• 1 3-pin header for connecting/disconnecting device
from external power
• 1 3-pin header to change signal path state of
device

1 Evaluation Module Overview
1.1 Introduction
This user’s guide describes the TMUX4827YBHEVM evaluation module (EVM) and the intended use. This board
allows for the quick prototyping and characterization of TI’s TMUX4827 multiplexers in an 9-Pin YBH package.
This EVM allows for evaluation of the signal path along with the power sequencing flexibility of the TMUX4827.
1.2 Kit Contents
The EVM kit includes the following :
• TMUX4827YBHEVM board
1.3 Specification
The TMUX4827YBHEVM is used for quick prototyping of the TMUX4827 in the YBH package. The EVM has two
3-pin headers. One header for toggling the SEL pin to switch control the signal path routing of the device. The
other 3-pin header allows for the VDD supply to be connected to an external source, to the board ground or left
floating.
The EVM has test points on each I/O for a total of six total test points that are rated up to 2 A to support testing
the TMUX4827 at the fullest current carrying capabilities. Seven extra ground test points are provided to allow
for easy testing of the board.

1.4 Device Information
The TMUX4827 is a complementary metal-oxide semiconductor (CMOS) multiplexer with two independently
selectable 2:1, single-pole, doublethrow (SPDT) switch channels. This device works with a single supply (1.8 to
5.5 V), but can pass bidirectional analog and digital signals beyond the supply from -12 V to 12 V.
The TMUX4827 also features powered off protection up to ±12 V, which isolates the Dx from a voltage on the Sx
even when there is no supply voltage present (VDD = 0 V). Without this protection feature, any voltage on the
switch can back-power the supply rail through an internal ESD diode and cause potential damage to the rest of
the system.
With 0.001% THD+N and 1 mΩ RON-flatness, the TMUX4827 is an excellent choice for passing precision
analog and audio signals without adding distortion.

2 Hardware
2.1 Power Requirements
TMUX4827YPHEVM requires a 1.8V to 5.5V supply provided either through the J1 terminal, or directly hooked
to the red VDD_EXT test point to provide a passive signal pathway between the Sx and Dx pins in according to
the logic selected.
2.2 Header and Jumper Information
The TMUX4827YBHEVM has two 3-pin headers to control the power supply connection, location C2 of the
TMUX4827, and the control inputs, location A2.
1. Supply Header J2
Header J2 connects the VDD pin to either the external power or to ground via a jumper. If Header J2 is not
connected, then the devices supply is left floating. Figure 2-1 shows header J2.
a. To connect to the external supply, short the J2-2 location on the header to J2-3. The VDD_EXT terminal
is now supplying the device power.
b. To connect to ground, short the J2-2 location on the header to J2-1. The device supply pin is now
grounded.
c. To leave the device supply pin floating, leave J2-2 unconnected and floating.
2. Control Header J7
Header J7 connects the SEL pin to either the external power or ground via a jumper. If Header J7 is not
connected, then the devices SEL pin are left floating.
a. To connect to the external supply, short the J7-2 location on the header to J7-1. The VDD_EXT terminal
is now connected to the devices SEL pin.
b. To connect to ground, GND, short the J7-2 location on the header to J7-3. The device SEL pin is now
grounded.
c. Leaving J7-2 unconnected leaves the SEL pin floating. Doing this is not recommended as the device is
in an unknown state.

FCC Interference Statement for Class A EVM devices
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
FCC Interference Statement for Class B EVM devices
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
3.2 Canada
3.2.1 For EVMs issued with an Industry Canada Certificate of Conformance to RSS-210 or RSS-247
Concerning EVMs Including Radio Transmitters:
