Product details
Overview
TS4962MEIJT from STMicroelectronics is a 3 W filter-free Class-D BTL audio power amplifier in a Flip Chip 9-bump package (300 µm bump diameter), operating from 2.4 V to 5.5 V supply, delivering 2.3 W into 4 Ω at 1% THD+N and 5 V, with 88% typical efficiency and 85 dB SNR - deployed in portable gaming consoles and VR headsets for low-noise, high-efficiency audio output.
For engineers reviewing the TS4962MEIJT datasheet, TS4962MEIJT pinout, TS4962MEIJT application, or TS4962MEIJT equivalent, key selection criteria include differential input architecture, standby current of 10 nA typ., adjustable gain via external resistors, PWM base frequency of 250 kHz, and pop/click suppression enabling <5 ms wake-up time.
Technical Context
The TS4962MEIJT implements a differential-input, BTL-output Class-D topology with internal PWM oscillator (180–320 kHz) and common-mode feedback loop, supporting single-ended or differential input configurations. Its gain is set externally via two matched resistors (e.g., 300 kΩ nominal), yielding precise 6 dB nominal gain with ±9% tolerance across supply voltages.
It features active low standby control (10 nA shutdown current), integrated pop-and-click reduction circuitry, and robust PSRR (63 dB @ 217 Hz) and CMRR (57 dB @ 217 Hz) - all optimized for battery-powered portable audio where supply ripple rejection and fast enable timing are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Power | 2.3 W into 4 Ω @ 5 V, 1% THD+N - sufficient for full-volume mono speaker drive in compact handhelds |
| Supply Voltage Range | 2.4 V to 5.5 V - compatible with single-cell Li-ion (3.0–4.2 V) and USB-powered (5 V) systems |
| Efficiency | 88% typ. @ 2 W into 4 Ω - minimizes thermal load and extends battery runtime vs. Class-AB alternatives |
| Signal-to-Noise Ratio | 85 dB A-weighted @ 0.9 W into 8 Ω - enables clean audio playback without audible background hiss |
| Wake-up Time | 5 ms max. - ensures near-instant audio response after standby activation in interactive devices |
| Standby Current | 10 nA typ. - supports multi-week shelf life in always-on portable electronics |
| PWM Frequency | 250 kHz typ. - enables use without external LC filter while maintaining EMI compliance in dense PCB layouts |
Pinout & Package
TS4962MEIJT uses a 9-bump Flip Chip package (300 µm bump diameter, 9 × 300 µm footprint), Pb-free, with bumps located on the die underside - requiring micro-BGA reflow assembly and underfill for mechanical reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Positive differential input | Accepts balanced audio signal; paired with IN− for common-mode noise rejection |
| IN− | Negative differential input | Completes differential pair; enables >57 dB CMRR and reduced EMI susceptibility |
| VDD | Analog power supply | 2.4–5.5 V input; requires local 1 µF + 100 nF decoupling per datasheet layout guidelines |
| GND | Power ground | Reference for all analog/digital signals; must be low-impedance plane beneath chip |
| STBY | Standby control (active low) | Pulling to GND disables output and reduces ICC to 10 nA; open or high enables operation |
| OUT+ | Positive BTL output | Drives one side of speaker load; swing amplitude ≈ VDD in push-pull mode |
| OUT− | Negative BTL output | Drives opposite speaker terminal; differential voltage = OUT+ − OUT− delivers full power |
Key Features
| Feature | Design Value |
|---|---|
| Differential input architecture | Enables >57 dB CMRR and immunity to board-level noise coupling in noisy portable environments |
| Adjustable gain via external resistors | Gain = 300 kΩ / Rin (kΩ); supports precise system-level gain tuning without IC change |
| Filter-free Class-D operation | 250 kHz PWM frequency eliminates need for external LC filter - saves board space and BOM cost |
| Low pop/click noise | Integrated soft-start and output stage sequencing limits transient artifacts to <5 ms wake-up |
| Ultra-low standby current | 10 nA typ. shutdown current preserves battery charge during extended idle periods |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Class-D audio amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS4962IDT | Same die, SO-8 package (5 mm × 4 mm) with exposed pad; higher RthJA (200 °C/W vs. 90 °C/W for Flip Chip) | Suitable for prototyping or lower-power applications where thermal margin is available and reflow compatibility is preferred | Select when board assembly lacks Flip Chip capability or when heatsinking via exposed pad is feasible |
| TAS5342AIDBTR | 3.2 W into 4 Ω @ 5 V, 1% THD+N; fixed 20 dB gain; requires external LC filter; 40-pin HTSSOP package | Targeted at higher-fidelity audio systems needing fixed-gain stability and higher channel count (dual-channel) | Choose only if filter-based design is acceptable and dual-channel operation is required - not drop-in compatible |
Compared with TS4962IDT, TS4962MEIJT offers superior thermal performance (90 vs. 200 °C/W) and smaller footprint but requires Flip Chip assembly; versus TAS5342AIDBTR, it eliminates external filtering and reduces board area by >70%, at the cost of programmable gain flexibility.

FAQ
What is the minimum recommended supply voltage for reliable operation?
The TS4962MEIJT operates down to 2.4 V per absolute maximum ratings and electrical characteristics tables. At 2.4 V, output power drops to 0.48 W into 4 Ω (1% THD+N), and the operating temperature range is limited to 0 °C to +70 °C. Full specification compliance requires ≥2.5 V supply.
Can the TS4962MEIJT drive an 8 Ω speaker effectively?
Yes - it delivers 1.4 W into 8 Ω at 5 V and 1% THD+N, and 0.45 W at 3.0 V. The device maintains >77% efficiency across load impedances ≥4 Ω, and its BTL architecture ensures optimal power transfer without external impedance matching networks.
Is external gain-setting resistor matching critical?
Yes - the datasheet specifies that Rin values must be matched within ±1% to maintain gain accuracy and minimize DC offset. Mismatch >2% increases output offset voltage and may degrade THD+N performance, especially at low signal levels.
Does the TS4962MEIJT require a heatsink in standard operation?
No - the 9-bump Flip Chip package has RthJA = 90 °C/W with 125 mm² copper pour, enabling 2.3 W output into 4 Ω at 5 V without external heatsinking at Tamb ≤ +60 °C. Thermal derating begins above 60 °C ambient per Figure 22 in the datasheet.
