Product details
Overview
TL3414AID from Texas Instruments is a dual operational amplifier designed for single- or dual-supply audio-amplifier 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 supply - enabling direct headphone driver implementation in DVD and CD-RW systems.
For engineers reviewing the TL3414AID datasheet, TL3414AID pinout, TL3414AID application, or TL3414AID equivalent, key selection considerations include its SOIC-8 package, rail-to-rail input common-mode range (VCC− to VCC+ − 2 V), 3.2 V output swing into 70 mA load at 5 V supply, and suitability for low-cost stereo line/headphone amplification where high output current and moderate bandwidth are required.
Technical Context
The TL3414AID integrates two independent high-output-current op-amps in a single SOIC-8 package, each with internally compensated unity-gain-stable architecture. It supports both single-supply (3–15 V) and split-supply (±1.5 V to ±7.5 V) operation, with input voltage range extending from VCC− to VCC+ − 2 V and output capable of sourcing/sinking 70 mA.
Its AC performance includes 0.83 V/µs slew rate and 18 nV/√Hz input noise at 1 kHz under 5 V supply, while DC characteristics feature 2–5 mV input offset voltage, 300–600 nA input bias current, and 77–100 dB large-signal voltage gain - optimized for cost-sensitive, medium-fidelity analog signal conditioning and buffer stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 15 V (single supply); enables direct integration into 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Output Current Drive | 70 mA per amplifier; sufficient to directly drive 32 Ω headphones or low-impedance transducers without external buffers. |
| Gain-Bandwidth Product | 1.1 MHz at VCC+ = 5 V; supports stable unity-gain and low-gain audio amplification up to ~100 kHz. |
| Slew Rate | 0.83 V/µs at 5 V; limits full-power bandwidth to ~210 kHz, appropriate for CD-quality audio (20 kHz) with low distortion. |
| Input Offset Voltage | 2–5 mV max; ensures ≤150 mV DC error at unity gain into 32 Ω load, minimizing audible pop/click on power-up. |
| Common-Mode Input Range | VCC− to VCC+ − 2 V; allows rail-to-rail input operation in single-supply configurations down to 3 V. |
| Output Voltage Swing | 3.2 V into 70 mA at 5 V supply; delivers >64% of rail-to-rail swing, supporting ≥1 Vrms audio output into 32 Ω. |
Pinout & Package
TL3414AID is housed in an 8-pin SOIC (D) package with 1.27 mm lead pitch, 3.9 mm body width, and 1.75 mm maximum height - compatible with standard surface-mount assembly processes and IPC-7351 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output; capable of sourcing/sinking 70 mA into resistive or capacitive loads. |
| 2 | IN1− | Inverting input of amplifier 1; high-impedance node (600 nA max bias current) for feedback network connection. |
| 3 | IN1+ | Non-inverting input of amplifier 1; accepts signals from VCC− to VCC+ − 2 V in single-supply mode. |
| 4 | VCC− | Negative supply rail (GND in single-supply mode); must be connected to system ground or negative rail. |
| 5 | IN2+ | Non-inverting input of amplifier 2; electrically identical to Pin 3, enabling dual-channel symmetric design. |
| 6 | IN2− | Inverting input of amplifier 2; used for feedback configuration matching amplifier 1's topology. |
| 7 | OUT2 | Amplifier 2 output; independently drives second channel (e.g., right earphone) with same 70 mA capability. |
| 8 | VCC+ | Positive supply rail; accepts 3–15 V; decoupling capacitor recommended adjacent to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual high-output-current amplifiers | Each channel delivers 70 mA continuous output, eliminating need for discrete output transistors in headphone driver designs. |
| Single/dual supply flexibility | Operates from 3–15 V single supply or ±1.5 V to ±7.5 V dual supply - simplifies power architecture across portable and line-powered systems. |
| Rail-to-rail input common-mode range | Accepts inputs from VCC− to VCC+ − 2 V, enabling direct coupling of AC signals without DC-blocking capacitors in many configurations. |
| Low input bias current | 300–600 nA typical; minimizes voltage error across high-impedance sensor or potentiometer interfaces. |
| Thermal protection | Unlimited output short-circuit duration supported; internal thermal shutdown prevents damage during fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher 3 MHz GBW but lower 25 mA output current; JFET-input (lower IIB = 65 pA) vs. bipolar (300–600 nA). | Better for high-impedance sensor interfaces; unsuitable for direct 32 Ω headphone drive due to limited output current. | Select TL072CDR when input bias current <100 pA is critical and load impedance ≥10 kΩ; avoid for low-Z audio loads. |
| LM833N | Higher 15 MHz GBW and 20 V/µs slew rate; rated for ±18 V supplies but only 30 mA output current; higher quiescent current (5.6 mA vs. 4 mA). | Targeted at high-fidelity preamp stages; insufficient output current for sustained 70 mA headphone drive. | Choose LM833N for wideband audio preamplification with low distortion; use TL3414AID where output current >50 mA is mandatory. |
Compared with TL072CDR and LM833N, TL3414AID uniquely balances 70 mA output drive, 1.1 MHz bandwidth, and SOIC-8 packaging - making it the only option among the three qualified for direct 32 Ω headphone amplification without external boost circuitry.

FAQ
What is the maximum output current capability of TL3414AID per channel?
The TL3414AID delivers up to 70 mA of continuous output current per amplifier channel when supplied with 5 V single supply, as verified in the SLOS453A datasheet under "High Output Current . . . 70 mA, VCC+ = 5 V". This rating applies to both channels simultaneously under thermal limits, and enables direct drive of 32 Ω headphones without external transistor stages. The device maintains this current capability across its full operating temperature range of −40°C to 85°C.
Can TL3414AID operate from a single 3.3 V supply?
Yes, TL3414AID supports single-supply operation from 3 V to 15 V, including 3.3 V. At 3.3 V, its common-mode input range extends from VCC− (GND) to VCC+ − 2 V (1.3 V), and output swing reaches approximately 1.1 V into 70 mA load per the datasheet's extrapolated performance curves. While output headroom is reduced versus 5 V operation, the TL3414AID remains functional for low-voltage headphone or line-driver applications where signal amplitude requirements are modest.
What is the pin 1 marking and orientation for TL3414AID in SOIC-8 package?
The TL3414AID uses standard SOIC-8 pin 1 identification: a small circular or rectangular mark located at the top-left corner of the package body when the part is oriented with the marking side up and the leads pointing downward. Per TI's D0008A package drawing, pin 1 is in quadrant Q1 of the tape-and-reel carrier, and the top-side marking "Z3414A" appears adjacent to pin 1. The device follows JEDEC MS-012 variation AA mechanical standards.
Does TL3414AID include internal ESD protection diodes on its inputs?
Yes, TL3414AID incorporates internal ESD protection diodes on both inputs (IN1± and IN2±), as confirmed by the absolute maximum ratings specifying input voltage limits of VCC− to VCC+ and ±10 mA input current. These diodes clamp transient overvoltage events to within safe operating limits, protecting the bipolar input stage. However, external series resistors are still recommended for sustained overvoltage conditions exceeding the diode conduction threshold (~0.6 V differential).
Is TL3414AID RoHS compliant and what is its moisture sensitivity level?
Yes, TL3414AID is RoHS compliant (lead-free, NIPDAU finish) and carries a Moisture Sensitivity Level (MSL) rating of Level-1 at 260°C peak reflow, meaning it has unlimited floor life and requires no baking prior to soldering. This MSL-1 classification is documented in TI's Package Option Addendum and applies to both tube (TL3414AID) and reel (TL3414AIDR) variants of the SOIC-8 packaged TL3414AID.
