Product details

Overview

TDA7292 from STMicroelectronics is a Class-AB dual-channel audio power amplifier in Multiwatt11 package, delivering 40 W + 40 W into 8 Ω at ±26 V with 10% THD. It integrates mute and standby functions, features split-supply operation up to ±33 V, and provides thermal/short-circuit protection-designed for stereo TV sets and hi-fi music centers.

For engineers reviewing the TDA7292 datasheet, TDA7292 pinout, TDA7292 application, or TDA7292 equivalent, key selection considerations include dual-rail supply compatibility, mute/standby voltage thresholds on Pin 5, output power vs. supply voltage curves, and thermal resistance (R_{th j-case} = 1.5 °C/W) for heatsink sizing.

Technical Context

The TDA7292 uses a fully differential input stage with internal biasing, supporting both dual-supply (±8 V to ±33 V) and single-supply configurations via external DC offset networks. Its open-loop gain is 80 dB and slew rate is 11 V/ms, enabling stable 20 Hz–20 kHz audio bandwidth with <0.02% THD at 1 W output.

Mute and standby are controlled by a single pin (Pin 5), referenced to +VS: mute activates at +VS − 6.0 V to +VS − 2.5 V (75 dB attenuation), standby engages below +VS − 2.5 V (110 dB attenuation, I_q = 8 mA). Thermal shutdown triggers at 145 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Power	40 W + 40 W into 8 Ω @ ±26 V, 10% THD - sufficient for full-range stereo speakers without external boost stages
Supply Voltage Range	±8 V to ±33 V - supports wide rail flexibility for legacy and high-performance audio systems
THD+N	0.02% @ 1 W, 1 kHz - low distortion preserves midrange clarity and vocal fidelity
Crosstalk	70 dB @ 1 kHz - ensures channel separation critical for stereo imaging
Input Resistance	20 kΩ - compatible with standard line-level preamp outputs without loading
Quiescent Current	50–130 mA @ ±26 V - enables efficient idle power management before mute/standby activation
Thermal Resistance	R_{th j-case} = 1.5 °C/W - defines minimum heatsink requirement for continuous 40 W/channel operation

Pinout & Package

The TDA7292 is housed in a vertical 11-pin Multiwatt package with exposed metal tab (connected to Pin 6, −VS) for thermal conduction. The package meets ECOPACK® environmental compliance standards.

Pin/Terminal	Circuit Role	Design Meaning
1	IN−(L)	Inverting input for left channel - used with external feedback network to set closed-loop gain
2	IN+(L)	Non-inverting input for left channel - accepts AC-coupled line-level signal via 1 μF capacitor
3	GND	Analog ground reference - must be star-connected to minimize ground loop noise
4	IN−(R)	Inverting input for right channel - independently configurable for balanced or unbalanced topology
5	MUTE/STANDBY	Control input referenced to +VS - voltage thresholds determine mute (75 dB) or standby (110 dB, 8 mA I_q) state
6	−VS	Negative supply rail - tab connection requires low-thermal-resistance mounting to heatsink
7	OUT(R)	Right channel output - drives speaker load directly; requires 100 nF stability capacitor to ground
8	+VS	Positive supply rail - decoupled with 1000 μF + 100 nF capacitors to suppress rail bounce
9	OUT(L)	Left channel output - symmetrical layout with OUT(R); PCB trace length matching recommended
10	IN+(R)	Non-inverting input for right channel - identical electrical behavior to IN+(L)
11	−VS (Tab)	Thermal pad / electrical connection to Pin 6 - mandatory mechanical attachment to heatsink for thermal safety

Key Features

Feature	Design Value
No "pop" at turn-on/off	Internal soft-start circuit eliminates transient voltage spikes during power sequencing - prevents speaker thump in consumer AV systems
Split-supply operation	Supports true bipolar rails up to ±33 V - enables high-voltage headroom for dynamic audio peaks without clipping
Mute function	75 dB attenuation with <10 µs response time - allows seamless source switching without audible artifacts
Standby mode	Reduces quiescent current to 8 mA while retaining fast wake-up - ideal for energy-conscious smart TVs and streaming devices
Integrated protection	Thermal shutdown (145 °C), short-circuit limiting (5 A peak), and SOA monitoring - eliminates need for external fault-handling circuitry

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel Class-AB audio amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TDA7265	Lower max supply (±26 V), 30 W + 30 W @ 8 Ω, no dedicated mute pin (requires external logic)	Targeted at cost-sensitive stereo receivers with simpler control requirements	Select when supply rails ≤ ±26 V and mute functionality can be implemented externally
LM4780	Higher THD (0.1% @ 1 W), no integrated standby, requires external thermal shutdown circuitry	Suitable for DIY audio kits where discrete protection and tuning are preferred	Choose only if design permits manual thermal management and higher distortion is acceptable

Compared with TDA7292, TDA7265 offers lower power and simplified control at reduced BOM cost, while LM4780 trades integration for greater external configurability-neither matches the TDA7292's combined mute/standby precision, thermal robustness, and 40 W/channel capability at ±33 V.

FAQ

What is the minimum supply voltage required for rated 40 W output?

The TDA7292 achieves 40 W + 40 W into 8 Ω only at ±26 V supply with 10% THD. At ±18 V, maximum output drops to 31 W into 4 Ω. Operation below ±8 V is outside absolute maximum ratings and will not sustain functional amplification.

How does the MUTE/STANDBY pin (Pin 5) interface with microcontroller GPIO?

Pin 5 is voltage-referenced to +VS, not ground. To assert mute, drive it to +VS − 4.5 V (midpoint of −6 V to −2.5 V range); for standby, drive below +VS − 2.5 V. A level-shifting resistor divider from 3.3 V GPIO is required-direct 0–3.3 V logic connection will not activate either mode.

Can the TDA7292 be used in bridged-tied-load (BTL) configuration?

No. The TDA7292 is strictly a dual-channel amplifier with independent output stages referenced to −VS. It lacks internal BTL control logic or complementary output pairs. Each channel must drive a grounded speaker load or transformer-coupled output.

What is the recommended heatsink thermal resistance for continuous 40 W/channel operation?

With R_{th j-case} = 1.5 °C/W and max junction temperature of 145 °C, ambient at 50 °C, and case-to-heatsink interface resistance of 0.5 °C/W, the heatsink must have R_{th sink-ambient} ≤ 2.7 °C/W to maintain safe junction temperature under full load.
