TAS5162DDV - 210W Stereo Class-D Amplifier | Texas Instruments
MPN: TAS5162DDV ✓ AktifTAS5162DDV Ringkasan
A Class-D audio amplifier is a switching power amplifier that uses pulse-width modulation to represent an analog audio waveform. It belongs to the broader power-amplifier hierarchy and converts digital or PWM control signals into high-current bridge-tied speaker outputs. Compared with a linear amplifier, a properly implemented Class-D stage can deliver high output power with lower power dissipation, making it suitable for home theater, multichannel audio, powered speakers, and compact high-performance sound systems.
The TAS5162DDV combines a 160 W stereo configuration with a 300 W mono capability in one integrated device. Each channel can deliver up to 210 W into 6 ohms at 10% THD, while the product page identifies improved protection, low integrated output noise, low THD+N without clipping, and low idle-power dissipation. Internal pull-up resistors on the shutdown and overtemperature-warning outputs can connect those signals to 3.3 V; external pull-ups support 5 V logic levels.
As a digital power stage, the device combines PWM command processing with integrated output-driver circuitry and an exposed-pad thermal interface. The 44-pin HTSSOP package provides the electrical connections required for PWM audio input, clocking, control, fault signaling, power rails, ground, and differential speaker outputs. Because output energy is dissipated in the power stage, the exposed thermal pad and PCB copper area are central to maintaining reliable operation at high continuous output power.
Typical uses include powered stereo speakers, home-theater amplifiers, multimedia speaker systems, active subwoofers, and high-output consumer audio equipment. The TAS5162 can also be configured for mono operation when greater output power is required. System designers should match the speaker impedance, supply capability, switching layout, and thermal design to the intended channel configuration.
For PCB implementation, place input and power decoupling close to the relevant device pins, connect the exposed pad to a properly sized thermal plane, and keep high-current speaker outputs away from sensitive audio inputs. The manufacturer datasheet's pin-description table and typical application circuit should govern net assignment, output-filter design, and thermal-pad connection.
This page organizes the TAS5162DDV's principal electrical ratings, protection features, application guidance, package information, and engineering trade-offs. It also highlights where pin-compatible substitutions require additional qualification rather than assuming that similar audio amplifiers are automatic board-level replacements.

Aplikasi Biasa
TAS5162DDV patut untuk 6 aplikasis: Powered Stereo Speakers, Home Theater Amplifier, Active Subwoofer, Powered Subwoofer, Multichannel Audio System, Portable Audio Infrastructure.
Powered Stereo Speakers
The TAS5162DDV fits powered stereo speakers that require high output from two integrated channels. Its 210 W per channel capability into a 6-ohm bridge-tied load at 10% THD provides useful headroom for music playback, while the 160 W stereo rating describes a lower-power operating point for design planning. The device is placed between the system's PWM audio source and the speaker outputs. Designers should size the 0 V to 52.5 V amplifier supply for continuous load, implement the recommended output filters, and connect the exposed pad to a substantial thermal plane so heat can leave the 44-pin HTSSOP efficiently.

Home Theater Amplifier
TAS5162DDV can serve as the stereo power stage in a home-theater amplifier, where two channels drive left and right speakers at substantial output levels. The 210 W per channel rating into 6 ohms at 10% THD is appropriate for high-volume listening, and the 160 W stereo configuration provides a practical system-level power target. The amplifier is driven by PWM audio commands and uses bridge-tied outputs. A successful implementation requires supply voltage headroom, inductor selection that matches the output power, careful separation of switching currents, and thermal management based on the exposed pad rather than the leads alone.
Disebarkan
Active Subwoofer
The TAS5162DDV is suitable for an active subwoofer or other high-power BTL speaker system when the amplifier is configured for mono operation. Texas Instruments specifies up to 300 W mono output, while each bridge-tied amplifier channel can reach 210 W into 6 ohms at 10% THD. This arrangement concentrates power in one speaker and requires the system integrator to reconcile the amplifier rating, speaker impedance, supply capability, and output-filter design. Because continuous low-frequency playback can produce sustained thermal load, the HTSSOP exposed pad should be tied to a carefully sized copper heat-spreading area with multiple thermal vias.

Powered Subwoofer
The TAS5162DDV can support a powered subwoofer platform built around a high-efficiency Class-D output stage. Its 210 W per-channel capability into a 6-ohm BTL load provides a practical basis for selecting the speaker and supply, while the 300 W mono specification supports higher-power configurations. The device's PWM interface allows it to work with a compatible digital audio processor rather than requiring a traditional analog input path. Critical implementation details include the recommended output filter, clean return-current routing, adequate supply decoupling, and continuous-load thermal analysis. The integrated protection system should also be monitored through the shutdown and overtemperature-warning outputs.
Disebarkan
Multichannel Audio System
TAS5162DDV can be used in a multichannel audio architecture where each device supplies two Class-D power channels. Its 210 W per-channel capability and 0 V to 52.5 V power supply range permit repeated amplifier sections to serve adjacent speakers when the power budget and cooling system are designed accordingly. Because the device accepts PWM audio commands, it fits systems that distribute digital audio through a common processor or bus. System planners should budget amplifier supply current, isolate switching energy from sensitive audio routing, allocate exposed-pad copper for each device, and use fault outputs for coordinated shutdown when protection events occur.
Disebarkan
Portable Audio Infrastructure
The TAS5162DDV can support portable or transportable audio infrastructure where high output power is needed from compact equipment. Its 160 W stereo and 210 W per-channel ratings make it suitable for performance-oriented powered speakers and related installations, provided the enclosure has a usable heat-transfer path. The exposed thermal pad is especially important in compact designs because less natural airflow can increase the temperature rise of the power stage. Engineers should verify enclosure dissipation, load-dependent efficiency, supply startup behavior, and output filtering. The 10.8 V to 13.2 V digital supply range must also be integrated with the system's control and processing rails.

Catatan Desain
Use the exposed pad as the primary thermal path and connect it to a continuous PCB ground plane with multiple short thermal vias. Estimate the required copper area from the highest sustained channel dissipation and the enclosure's heat-transfer conditions. Keep the thermal-via current path short so heat from the power stage does not depend on thin surface-mount traces.
Place the input, supply, and decoupling components close to their associated pins. Keep the high-current output loops compact and route them away from PWM audio inputs and control traces. Use the manufacturer land pattern rather than treating the 44-pin HTSSOP as a generic TSSOP footprint, because the exposed-pad connection and thermal requirements are integral to reliable operation.
Size the 0 V to 52.5 V amplifier supply for the selected stereo or mono configuration, including continuous speaker load and transient demand. Keep the 10.8 V to 13.2 V digital supply clean and decoupled. Account for startup current, amplifier efficiency, and any inrush into the output network so the supply does not become the limiting factor during high-level playback.
Do not assume that two 210 W channel ratings can be loaded independently without checking the total supply capability and thermal budget. Use bridge-tied speaker wiring, verify that the speaker impedance meets the 6-ohm reference condition, and include the correct output-filter components. Monitor shutdown and overtemperature-warning outputs rather than relying only on normal audio playback.
Preserve the integrity of the PWM audio command path by keeping it away from high-current switching nets and by following the datasheet's grounding recommendations. External pull-up resistors are required when the shutdown or overtemperature-warning signals must operate with 5 V logic; the internal pull-ups target 3.3 V. Validate thresholds, rise times, and fault-response timing in the finished control system.
