13 Device and Documentation Support

13.1 Device Support

13.1.1 Device Nomenclature

The glossary listed in the Glossary section is a general glossary with commonly used acronyms and words which

are defined in accordance with a broad TI initiative to comply with industry standards such as JEDEC, IPC, IEEE,

and others. The glossary provided in this section defines words, phrases, and acronyms that are unique to this

product and documentation, collateral, or support tools and software used with this product. For any additional

questions regarding definitions and terminology, please see the e2e Audio Amplfier Forum.

Bridge tied load (BTL) is an output configuration in which one terminal of the speaker is connected to one half-

bridge and the other terminal is connected to another half-bridge.

DUT refers to a device under test to differentiate one device from another.

Closed-loop architecture describes a topology in which the amplifier monitors the output terminals, comparing

the output signal to the input signal and attempts to correct for non-linearities in the output.

Dynamic controls are those which are changed during normal use by either the system or the end-user.

GPIO is a general purpose input/output pin. It is a highly configurable, bi-directional digital pin which can perform

many functions as required by the system.

Host processor (also known as System Processor, Scalar, Host, or System Controller) refers to device

which serves as a central system controller, providing control information to devices connected to it as well as

gathering audio source data from devices upstream from it and distributing it to other devices. This device often

configures the controls of the audio processing devices (like the ) in the audio path in order to optimize the audio

output of a loudspeaker based on frequency response, time alignment, target sound pressure level, safe

operating area of the system, and user preference.

Maximum continuous output power refers to the maximum output power that the amplifier can continuously

deliver without shutting down when operated in a 25°C ambient temperature. Testing is performed for the period

of time required that their temperatures reach thermal equilibrium and are no longer increasing

Parallel bridge tied load (PBTL) is an output configuration in which one terminal of the speaker is connected to

two half-bridges which have been placed in parallel and the other terminal is connected to another pair of half

bridges placed in parallel

rDS(on) is a measure of the on-resistance of the MOSFETs used in the output stage of the amplifier.

Static controls/Static configurations are controls which do not change while the system is in normal use.

Vias are copper-plated through-hole in a PCB.
