Product details
Overview
TL3414AIDR from Texas Instruments is a dual operational amplifier designed for single- or dual-supply audio amplification, featuring 70 mA output current capability, 3 V to 15 V wide supply range, and 1.1 MHz gain-bandwidth product at 5 V - optimized for headphone driver circuits in DVD and CD-RW systems.
For engineers reviewing the TL3414AIDR datasheet, TL3414AIDR pinout, TL3414AIDR application, or TL3414AIDR equivalent, key selection criteria include output drive strength under load, rail-to-rail input common-mode range (VCC+ − 2 V), low input offset voltage (2–5 mV), and SOIC-8 thermal performance (θJA = 97°C/W).
Technical Context
The TL3414AIDR integrates two independent high-output-current op-amps with internally compensated unity-gain stable architecture. Its input stage supports common-mode voltages down to VCC− and up to VCC+ − 2 V, enabling direct interfacing with DAC outputs in single-supply audio paths.
Each amplifier delivers 3.2 V output swing into 70 mA load at VCC+ = 5 V, with slew rate of 0.83 V/µs and 18 nV/√Hz input noise at 1 kHz - characteristics aligned with line-level and headphone buffer requirements rather than precision instrumentation or high-speed signal conditioning.
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 portable battery-powered and line-powered audio systems. |
| Output Current | 70 mA per channel - sufficient to drive 32 Ω headphones directly without external boost stages. |
| Gain-Bandwidth Product | 1.1 MHz at VCC+ = 5 V - enables stable unity-gain buffering and moderate-gain preamplifier configurations. |
| Input Offset Voltage | 2–5 mV - limits DC error in AC-coupled headphone outputs; avoids audible pop during power-up. |
| Slew Rate | 0.83 V/µs at 5 V - supports full-scale 20 kHz sine wave output without distortion at typical headphone voltage levels. |
| Common-Mode Input Range | VCC− to VCC+ − 2 V - accommodates ground-referenced input signals in single-supply designs. |
| Thermal Resistance θJA | 97°C/W (SOIC-8 package) - defines maximum power dissipation margin under continuous 70 mA load at ambient temperature. |

| 3 | IN1+ | Non-inverting input of Amp 1 - accepts audio signal source or reference bias point. |
| 4 | VCC− | Negative supply rail (0 V in single-supply mode) - serves as analog ground return path. |
| 5 | IN2+ | Non-inverting input of Amp 2 - accepts right-channel audio signal or auxiliary sensor input. |
| 6 | IN2− | Inverting input of Amp 2 - configured for gain-setting feedback network or signal inversion. |
| 7 | OUT2 | Amplifier 2 output - drives right-channel headphone load or stereo line driver output. |
| 8 | VCC+ | Positive supply rail - powers both amplifiers; supports up to 15 V for extended headroom. |
Key Features

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 |
|---|---|---|---|
| LM833N | Higher GBW (15 MHz), lower noise (4.5 nV/√Hz), but only 30 mA output current and no guaranteed 3 V operation. | Better suited for preamplifier gain stages than direct headphone driving; requires higher supply or external boost for 32 Ω loads. | Select LM833N when signal conditioning precedes a separate headphone amp; avoid for direct-drive headphone applications. |
| TPA6130A2 | Dedicated stereo headphone amplifier with 150 mW/channel into 16 Ω, integrated charge pump for rail-splitting, and shutdown control. | Replaces TL3414AIDR in new designs requiring higher output power, lower THD, or active power management - but adds complexity and cost. | Choose TPA6130A2 for premium audio quality or battery-life optimization; retain TL3414AIDR for cost-sensitive, space-constrained legacy-compatible designs. |
Compared with LM833N and TPA6130A2, the TL3414AIDR provides a balanced trade-off of drive strength, supply flexibility, and integration level - delivering verified 70 mA output at 3–15 V with minimal external components, making it optimal for mid-tier consumer audio where simplicity and BOM cost are prioritized over ultra-low noise or high-efficiency power delivery.

FAQ
What is the maximum output current specification for TL3414AIDR?
The TL3414AIDR delivers up to 70 mA per channel into resistive loads, verified at VCC+ = 5 V and TA = 25°C. This rating applies continuously under thermal limits defined by θJA = 97°C/W and maximum junction temperature of 150°C. The device maintains this output capability across its full operating temperature range (−40°C to 85°C) when PCB layout and ambient conditions meet recommended thermal guidelines.
Can TL3414AIDR operate from a single 3.3 V supply?
Yes, TL3414AIDR supports single-supply operation from 3 V minimum, making it fully compatible with 3.3 V systems. At 3.3 V, it provides ≥2.3 V output swing into high-impedance loads and maintains functional common-mode input range from 0 V to 1.3 V - sufficient for interfacing with 3.3 V DACs using appropriate biasing. Full 70 mA drive is achievable, though output voltage swing reduces proportionally with supply voltage.
What is the pin 1 marking and orientation for TL3414AIDR?
TL3414AIDR uses standard SOIC-8 pin 1 identification: a laser-marked dot or notch located at the top-left corner of the package when viewed from the top with the marking side up and leads pointing downward. The top-side marking "Z3414A" appears adjacent to pin 1, and tape-and-reel packaging follows quadrant Q1 orientation per TI's packaging specification.
Does TL3414AIDR require external compensation capacitors?
No, TL3414AIDR is internally compensated for unity-gain stability and does not require external compensation components. Its gain-bandwidth product is fixed at 1.1 MHz (at 5 V) and 2 MHz (at 8.6 V), allowing stable operation in inverting, non-inverting, and follower configurations without added capacitors - simplifying layout and reducing bill-of-materials count.
Is TL3414AIDR suitable for automotive applications?
TL3414AIDR is rated for −40°C to +85°C operating temperature and meets industrial-grade reliability standards, but it is not AEC-Q200 qualified or specified for automotive use. For automotive infotainment or telematics systems, TI recommends AEC-Q200 qualified alternatives such as the OPA1678 or TPA6132A2, which provide enhanced ESD tolerance, wider temperature range, and automotive-specific qualification documentation.
