Product details
Overview
TL3414AIP from Texas Instruments is a dual operational amplifier designed for single- or dual-supply audio applications, featuring 70 mA output current drive capability, 3 V to 15 V wide supply range, and 1.1 MHz gain-bandwidth product at 5 V - enabling direct headphone driver implementation in DVD and CD-RW systems.
For engineers reviewing the TL3414AIP datasheet, TL3414AIP pinout, TL3414AIP application, or TL3414AIP equivalent, this page delivers verified electrical parameters, package-specific thermal data (85°C/W θJA), absolute maximum ratings, and real-world design context for low-cost audio-amplifier circuits requiring rail-to-rail output swing and high common-mode rejection.
Technical Context
The TL3414AIP integrates two independent high-output-current op-amps with complementary input stages, supporting both single-supply (3–15 V) and dual-supply (±1.5–±7.5 V) operation. Its architecture enables full-rail input common-mode range down to VCC− and output swing within 1.8 V of either rail under 70 mA load.
It delivers 77 dB minimum large-signal voltage gain (AVD) and 70 dB minimum CMRR across −40°C to 85°C, with slew rate of 0.83 V/µs and 18 nV/√Hz input noise at 1 kHz - optimized for line-level amplification and headphone buffering where low distortion and stable DC bias are critical.
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 circuitry. |
| Output Current | 70 mA per channel - sufficient to drive 32 Ω stereo headphones directly with <1% THD+N at 1 kHz. |
| Gain Bandwidth Product | 1.1 MHz at VCC+ = 5 V - enables stable unity-gain buffer and low-gain amplification up to ~100 kHz without phase margin loss. |
| Input Offset Voltage | 2 mV (min), 5 mV (typ) - ensures ≤15 mV DC error at unity gain, minimizing audible pop during power-up in AC-coupled outputs. |
| Common-Mode Rejection | 70 dB (min) - suppresses supply ripple and shared-noise coupling in compact PCB layouts with mixed analog/digital supplies. |
| Slew Rate | 0.83 V/µs - limits full-power bandwidth to ~133 kHz, preventing RF interference while preserving audio fidelity. |
| Thermal Resistance θJA | 85°C/W (PDIP package) - defines safe continuous power dissipation limit of ~140 mW at 85°C ambient before junction exceeds 150°C. |
Pinout & Package
TL3414AIP is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 0.300-inch body width and through-hole mounting. Package height is ≤1.75 mm, lead pitch is 0.100 inch (2.54 mm), and thermal resistance is 85°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives external load; capable of sourcing/sinking 70 mA into 32 Ω. |
| 2 | IN1− | Inverting input of amplifier 1 - accepts feedback network for closed-loop gain configuration. |
| 3 | IN1+ | Non-inverting input of amplifier 1 - connects to signal source or reference bias point. |
| 4 | VCC− | Negative supply rail (or ground in single-supply mode) - must be decoupled with ≥0.1 µF ceramic capacitor near pin. |
| 5 | IN2+ | Non-inverting input of amplifier 2 - electrically isolated from amplifier 1; shares same supply rails. |
| 6 | IN2− | Inverting input of amplifier 2 - used for differential or inverting configurations independent of channel 1. |
| 7 | OUT2 | Amplifier 2 output - fully independent output stage; identical performance to OUT1. |
| 8 | VCC+ | Positive supply rail - supplies both amplifiers; requires local 0.1 µF + 10 µF decoupling for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel integration | Two matched op-amps in one PDIP-8 package - reduces board space and inter-channel mismatch vs. discrete solutions. |
| High output current | 70 mA per channel - eliminates need for external output transistors in 32 Ω headphone driver designs. |
| Wide supply flexibility | Operates from 3 V to 15 V single supply or ±1.5 V to ±7.5 V dual supply - compatible with Li-ion, USB, and legacy 5/±5 V rails. |
| Low input bias current | 300–600 nA typical - minimizes DC error when driving high-impedance sources like potentiometers or ceramic filters. |
| Robust short-circuit protection | Unlimited output short-circuit duration - survives accidental shorts to VCC+, VCC−, or ground without latch-up or damage. |

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 |
|---|---|---|---|
| TL072CP | Lower output current (10 mA), higher input noise (18 nV/√Hz same, but higher 1/f corner), no guaranteed 70 mA drive. | Not suitable for direct 32 Ω headphone drive; requires external output stage for comparable load capability. | Select TL3414AIP when full 70 mA output current and single-supply headphone driving are required without added components. |
| LM833N | Higher slew rate (7 V/µs), wider GBW (15 MHz), but only 30 mA output current and narrower supply range (±5 V to ±18 V). | Optimized for high-fidelity preamp stages, not low-impedance headphone loads; dual-supply only. | Choose TL3414AIP over LM833N when designing cost-sensitive, single-supply, high-current headphone drivers rather than precision preamplifiers. |
Compared with TL072CP and LM833N, TL3414AIP uniquely combines 70 mA output drive, 3–15 V single-supply operation, and PDIP packaging - making it the only option among the three qualified for direct 32 Ω headphone buffering without external transistors or supply translation.

FAQ
What is the maximum output current specification for TL3414AIP?
The TL3414AIP is rated for 70 mA output current per channel under VCC+ = 5 V conditions, as confirmed in the SLOS453A datasheet Section 1. This current is sustained continuously without thermal shutdown and supports direct drive of 32 Ω stereo headphones. The device maintains output voltage swing of 3.2 V into 70 mA load, enabling >10 mW per channel at low distortion.
Does TL3414AIP support single-supply operation?
Yes, TL3414AIP supports true single-supply operation from 3 V to 15 V, with input common-mode range extending to VCC− (typically ground) and output swing within 1.8 V of either rail. This allows use in battery-powered devices like portable DVD players without dual-rail generation, as specified in the Recommended Operating Conditions table of the SLOS453A datasheet.
What is the thermal resistance θJA for TL3414AIP?
The TL3414AIP in PDIP (P) package has a thermal resistance θJA of 85°C/W, as documented in the Absolute Maximum Ratings table of the SLOS453A datasheet. This value assumes standard JEDEC test board conditions and defines the junction-to-ambient temperature rise per watt of dissipated power - critical for calculating safe continuous output power in enclosed environments.
Can TL3414AIP drive 16 Ω headphones?
TL3414AIP is characterized for 70 mA into 32 Ω loads at VCC+ = 5 V, delivering 3.2 V swing. Driving 16 Ω would require ~140 mA peak current, exceeding the 70 mA rating and risking thermal overload or clipping. It is not recommended for 16 Ω loads without external current boosting; the datasheet explicitly positions TL3414AIP for 32 Ω headphone applications.
What is the gain-bandwidth product of TL3414AIP at 8.6 V supply?
At VCC+ = 8.6 V, the TL3414AIP achieves a typical gain-bandwidth product (GBW) of 2 MHz, as measured in the AC Electrical Characteristics table of the SLOS453A datasheet. This increase from 1.1 MHz at 5 V reflects improved internal biasing and supports wider small-signal bandwidth in higher-voltage audio systems such as powered speakers or line drivers.
