Product details
Overview
TS2007EIJT from STMicroelectronics is a 3 W filter-free Class-D audio power amplifier in a 9-bump flip-chip package, delivering 1.4 W into 8 Ω at 5 V with ≤1% THD+N, 86% typical efficiency, and selectable 6 dB or 12 dB fixed gain via the GS pin. It operates from 2.4 V to 5.5 V and integrates thermal shutdown, output short-circuit protection, and low-pop/click startup for portable audio systems.
For engineers reviewing the TS2007EIJT datasheet, TS2007EIJT pinout, TS2007EIJT application, or TS2007EIJT equivalent, key selection criteria include its differential input architecture, 280 kHz PWM base frequency, 90 dB SNR (A-weighted), 1 µA standby current, and compatibility with single-ended or differential input configurations in space-constrained mobile designs.
Technical Context
The TS2007EIJT employs a fully differential input stage with internal common-mode feedback, supporting both differential and single-ended inputs via external capacitor coupling. Its 280 kHz PWM carrier enables compact LC output filtering or direct filterless speaker drive with ferrite bead suppression.
Gain selection is implemented via a logic-level GS pin (6 dB at GND, 12 dB at VCC), while active-low STDBY enables 1 µA ultra-low-power shutdown. Thermal shutdown triggers at 150 °C, and output short-circuit protection operates without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Power | 1.4 W into 8 Ω @ 5 V, 1% THD+N - sufficient for mono loudspeaker in smartphones and PDAs |
| Supply Voltage Range | 2.4 V to 5.5 V - compatible with single-cell Li-ion and Li-poly battery rails |
| Efficiency | 86% typ. @ 1.4 W/8 Ω - reduces thermal load and extends battery life vs. Class-AB |
| PSRR | 68 dB @ 217 Hz, 6 dB gain - suppresses power supply ripple without external regulation |
| SNR | 90 dB A-weighted - ensures clean audio playback with minimal background noise |
| Standby Current | 1 µA typ. - enables rapid system-level power gating in always-on audio subsystems |
| PWM Frequency | 280 kHz typ. - balances EMI control and LC filter size for portable form factors |
Pinout & Package
TS2007EIJT uses a 9-bump flip-chip lead-free package with back coating option, measuring 1.5 mm × 1.5 mm × 0.55 mm (max), optimized for high-density PCB layouts in mobile devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Differential positive input | Accepts AC-coupled or DC-coupled audio signal; forms balanced pair with IN− |
| IN− | Differential negative input | Enables common-mode noise rejection; required for full PSRR and CMRR performance |
| VCC | Power supply input | Supplies 2.4–5.5 V; requires local 1 µF ceramic decoupling per datasheet Figure 2 |
| GND | Ground reference | Low-impedance return path for power and signal; must be connected to thermal pad |
| GS | Gain select input | Logic-low = 6 dB gain; logic-high = 12 dB gain; internal 300 kΩ pull-up defaults to 6 dB |
| STDBY | Standby control (active low) | Pulling to GND reduces ICC to 1 µA; internal 300 kΩ pull-down ensures default standby if floating |
| OUT+ | Differential positive output | Drives speaker terminal or LC filter; requires ferrite bead for EMI compliance in filterless mode |
| OUT− | Differential negative output | Completes H-bridge output stage; phase-inverted relative to OUT+ for differential drive |
| NC | No-connect bump | Unused mechanical bump; no electrical connection or routing required |
Key Features
| Feature | Design Value |
|---|---|
| Filter-free operation | Direct speaker drive without external LC filter - saves board space and BOM cost in thin mobile designs |
| Ultra-low standby current | 1 µA typical - enables seamless integration into low-power audio subsystems with fast wake-up (1 ms) |
| Dual fixed-gain configuration | 6 dB or 12 dB via single GPIO - eliminates need for external gain-setting resistors or digital control |
| Integrated protection | Thermal shutdown + output short-circuit protection - removes requirement for discrete fault management circuitry |
| Low pop-and-click noise | <1 ms startup time with internal soft-start - eliminates audible transients during playback activation |

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 |
|---|---|---|---|
| MAX9718ETA+ | 2.5 W into 8 Ω @ 5 V; 1.2 µA standby; requires external LC filter | Higher THD+N (0.15% vs. 0.12%) and no filterless mode - demands more board area | Select when strict EMI certification requires full LC filtering and higher output voltage swing is needed |
| TAS5086RTJR | 4.5 W into 8 Ω @ 5 V; I²C programmable gain; 2.5 µA standby; 32-pin QFN | Larger footprint (5 mm × 5 mm), digital interface overhead, and higher quiescent current | Choose for multi-channel systems requiring dynamic gain adjustment and channel synchronization |
Compared with MAX9718ETA+ and TAS5086RTJR, TS2007EIJT offers the smallest footprint (1.5 mm × 1.5 mm), true filterless operation, and lowest standby current - making it optimal for ultra-thin single-speaker portable devices where space and battery life are critical.

FAQ
What is the minimum recommended load impedance for TS2007EIJT?
The absolute minimum load resistor is 3.2 Ω per absolute maximum ratings, but the device is characterized and guaranteed for stable operation with ≥4 Ω loads. Driving lower impedances risks thermal shutdown due to increased current and reduced efficiency, especially at higher supply voltages or ambient temperatures above 60 °C.
Can TS2007EIJT operate with a single-ended input?
Yes - the TS2007EIJT supports single-ended input via AC coupling of the signal to IN+ while grounding IN− through a 1 µF capacitor, as shown in Figure 45 of the datasheet. Input impedance remains ~75 kΩ, and THD+N performance is maintained within 0.02% of differential mode at 1 kHz and 1.4 W output.
How does the GS pin function when left unconnected?
When the GS pin is unconnected, its internal 300 kΩ pull-up resistor biases it to VCC, selecting the 12 dB gain configuration by default. To ensure 6 dB gain, GS must be actively pulled to GND; floating or high-impedance states are not recommended for production designs due to potential noise susceptibility.
Is an LC output filter mandatory for TS2007EIJT?
No - the TS2007EIJT is explicitly designed for filterless operation using only a ferrite chip bead on each output (Figure 46), reducing BOM count and PCB area. An LC filter (Figure 47) may be added for stricter EMI compliance, but it degrades efficiency by ~3% and adds 3–4 passive components per channel.
