Product details
Overview
TL3414AIDRE4 from Texas Instruments is a dual operational amplifier designed for single- or dual-supply audio applications, featuring 70 mA output drive capability, 3 V to 15 V wide supply range, and 1.1 MHz gain-bandwidth product at 5 V supply - enabling direct headphone driver implementation in DVD/CDRW systems.
For engineers reviewing the TL3414AIDRE4 datasheet, TL3414AIDRE4 pinout, TL3414AIDRE4 application, or TL3414AIDRE4 equivalent, key selection criteria include output current capability (70 mA), rail-to-rail input common-mode range (VCC− to VCC+ − 2 V), slew rate (0.83 V/µs), and SOIC-8 packaging with industrial temperature range (−40°C to 85°C).
Technical Context
The TL3414AIDRE4 integrates two independent high-output-current op-amps in a single SOIC-8 package, supporting both single-supply (3–15 V) and split-supply (±1.5 V to ±7.5 V) operation. Its internal architecture delivers high open-loop gain (77–105 dB) and robust CMRR (70–90 dB), optimized for low-distortion analog signal amplification.
It features rail-compatible inputs (VICR = VCC− to VCC+ − 2 V), output swing of 3.2 V into 70 mA load at 5 V supply, and thermal performance rated at θJA = 97°C/W. The device is not rail-to-rail output but achieves >65% of full rail under heavy load - critical for line/headphone driver stages requiring headroom and stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 15 V (single supply); ±1.5 V to ±7.5 V (dual supply) - supports battery-powered and line-powered audio systems without level-shifting. |
| Output Current | 70 mA per amplifier - sufficient to drive 16 Ω headphones directly without external buffer stage. |
| Gain-Bandwidth Product | 1.1 MHz at 5 V - enables stable unity-gain headphone amplification with adequate phase margin. |
| Slew Rate | 0.83 V/µs at 5 V - limits large-signal distortion in audio band (20 Hz–20 kHz) while maintaining fidelity. |
| Input Offset Voltage | 2–5 mV - ensures low DC error in AC-coupled headphone outputs, minimizing pop/click on power-up. |
| Common-Mode Input Range | VCC− to VCC+ − 2 V - allows input signals near ground in single-supply configurations, simplifying biasing. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and consumer embedded audio equipment environments. |
Pinout & Package
TL3414AIDRE4 is housed in an 8-pin SOIC (D) package (5.3 mm × 6.2 mm, 1.75 mm max height), RoHS-compliant, with NIPDAU lead finish and moisture sensitivity level (MSL) 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives first channel load (e.g., left headphone speaker). |
| 2 | IN1− | Inverting input of Amp 1 - used for feedback configuration or inverting gain stage. |
| 3 | IN1+ | Non-inverting input of Amp 1 - accepts input signal for non-inverting amplification. |
| 4 | VCC− | Negative supply rail (ground in single-supply mode) - reference for all internal circuitry. |
| 5 | IN2+ | Non-inverting input of Amp 2 - accepts second-channel input (e.g., right audio channel). |
| 6 | IN2− | Inverting input of Amp 2 - enables differential or inverting configuration for second channel. |
| 7 | OUT2 | Amplifier 2 output - drives second channel load (e.g., right headphone speaker). |
| 8 | VCC+ | Positive supply rail - powers both amplifiers; supports up to 15 V for higher output swing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual high-output-current op-amps | 70 mA per channel enables direct 16–32 Ω headphone driving without discrete buffers. |
| Wide single-supply voltage range | 3 V to 15 V accommodates Li-ion (3.7 V), USB (5 V), and legacy 9–12 V rails in portable/desktop audio. |
| Industrial temperature rating | −40°C to +85°C ensures reliability in automotive infotainment, set-top boxes, and embedded media players. |
| Low input bias current | 300–600 nA minimizes DC offset drift in high-impedance sensor or DAC interface applications. |
| High PSRR and CMRR | 80–90 dB supply rejection and 70–90 dB common-mode rejection reduce noise coupling in noisy digital systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp audio driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Lower output current (40 mA), lower GBW (1 MHz), rail-to-rail output (TL3414AIDRE4 is not RRO), smaller input offset (1.5 mV typ). | Best suited for line-out or low-impedance pre-driver stages; insufficient for direct 16 Ω headphone drive. | Select LMV358IDR only when load impedance ≥ 100 Ω and supply is ≤ 5.5 V. |
| TL072CP | Higher VCC+ limit (18 V), JFET input (50 pA bias), lower noise (18 nV/√Hz same), but only 10 mA output current and no 70 mA spec. | Preferred for high-impedance sensor buffering or line-level mixing; unsuitable for headphone loads due to current limitation. | Choose TL072CP for low-noise, high-Z signal conditioning - not for power output stages. |
Compared with LMV358IDR and TL072CP, TL3414AIDRE4 uniquely combines 70 mA output drive, 3–15 V supply flexibility, and SOIC-8 industrial qualification - making it the only option among the three capable of direct 16–32 Ω headphone amplification without external components.

FAQ
What is the maximum output current specification for TL3414AIDRE4?
The TL3414AIDRE4 is specified for 70 mA output current per amplifier at VCC+ = 5 V, as confirmed in the "DC Electrical Characteristics" table of the SLOS453A datasheet. This rating applies under continuous DC conditions with thermal limits observed and enables direct drive of 16–32 Ω headphones without external transistors or buffers.
Does TL3414AIDRE4 support single-supply operation?
Yes, TL3414AIDRE4 supports true single-supply operation from 3 V to 15 V, with input common-mode range extending from VCC− (ground) to VCC+ − 2 V. This allows use in battery-powered devices like portable DVD players where only a positive rail is available, and simplifies biasing for AC-coupled audio paths.
What is the package type and lead finish of TL3414AIDRE4?
TL3414AIDRE4 is supplied in an 8-pin SOIC (D) package with dimensions 5.3 mm × 6.2 mm and maximum height of 1.75 mm. It features NIPDAU (nickel-palladium-gold) lead finish, RoHS compliance, and MSL Level-1 rating for unlimited floor life at 260°C peak reflow.
Can TL3414AIDRE4 be used in dual-supply configurations?
Yes, TL3414AIDRE4 is fully specified for dual-supply operation with VCC+ ranging from ±1.5 V to ±7.5 V. The absolute maximum rating allows ±7.5 V supplies (15 V total), and electrical characteristics including input offset, CMRR, and output swing are validated across this range per the datasheet's "Recommended Operating Conditions" table.
What is the gain-bandwidth product and slew rate of TL3414AIDRE4 at 5 V supply?
At VCC+ = 5 V and TA = 25°C, TL3414AIDRE4 has a typical gain-bandwidth product of 1.1 MHz and a slew rate of 0.83 V/µs, as documented in the "AC Electrical Characteristics" section of the SLOS453A datasheet. These values ensure stable unity-gain performance and low distortion in audio-frequency applications up to 20 kHz.
