Texas Instruments TL3414AIPG4

Overview

TL3414AIPG4 from Texas Instruments is a dual operational amplifier designed for single- or dual-supply audio amplification, featuring 70 mA output current drive capability, 3 V to 15 V wide supply range (single), and 1.1 MHz gain-bandwidth product at 5 V. It delivers 3.2 V output swing into 70 mA load and supports headphone driver applications in DVD and CD-RW systems.

For engineers reviewing the TL3414AIPG4 datasheet, TL3414AIPG4 pinout, TL3414AIPG4 application, or TL3414AIPG4 equivalent, key selection criteria include output current capability under load, rail-to-rail input common-mode range (VCC+ − 2 V), slew rate (0.83 V/µs), supply-voltage rejection ratio (80–90 dB), and SOIC-8 thermal performance (θJA = 97°C/W).

Technical Context

The TL3414AIPG4 integrates two independent high-output-current op-amps with internally compensated unity-gain-stable architecture. Its input stage supports common-mode voltage up to VCC+ − 2 V and down to VCC−, enabling operation near ground in single-supply configurations.

Each amplifier provides 77–105 dB large-signal voltage gain (AVD), 70–90 dB CMRR, and 80–90 dB kSVR across 5 V and 8.6 V supplies. Output stage is optimized for capacitive loads and 70 mA continuous sourcing/sinking without external boost components.

Key Specifications

Pinout & Package

TL3414AIPG4 is housed in an 8-pin SOIC (D) package with 1.27 mm pitch, 3.91 mm body width, and 1.75 mm max height. Pin 1 is located at the top-left corner with notch or beveled edge marking.

FAQ

What is the maximum output current capability of TL3414AIPG4?

The TL3414AIPG4 delivers up to 70 mA of continuous output current per amplifier channel when supplied with 5 V single supply. This is verified under IO = 70 mA, VCC+ = 5 V conditions in the datasheet, enabling direct drive of 32 Ω stereo headphones without external transistors or boost circuits. The TL3414AIPG4 maintains this current capability across its full operating temperature range of −40°C to 85°C.

Can TL3414AIPG4 operate from a single 3.3 V supply?

Yes, TL3414AIPG4 supports single-supply operation from 3 V to 15 V, including 3.3 V. At 3.3 V, it provides ≥2.5 V output swing into high-impedance loads and maintains functional common-mode input range from GND to VCC+ − 2 V (i.e., 0 V to 1.3 V). However, 70 mA output current is specified at 5 V and 8.6 V; performance at 3.3 V should be validated per application load.

Is TL3414AIPG4 pin-compatible with other dual op-amps in SOIC-8?

No, TL3414AIPG4 uses a standard dual op-amp pinout (OUT1, IN1−, IN1+, VCC−, VCC+, IN2+, IN2−, OUT2), which matches industry convention but is not guaranteed pin-compatible with all SOIC-8 dual op-amps due to internal architecture differences. Always verify pin function mapping against target replacement part's datasheet before substitution.

What is the thermal resistance (θJA) of TL3414AIPG4 in SOIC-8 package?

The TL3414AIPG4 in SOIC-8 (D) package has a junction-to-ambient thermal resistance (θJA) of 97°C/W, measured per JEDEC standards. This value assumes standard 2-layer PCB layout with no copper pour enhancement. For sustained 70 mA output into low-impedance loads, thermal design must ensure ambient temperature remains below 75°C to keep junction temperature under 150°C maximum rating.

Does TL3414AIPG4 support rail-to-rail input or output operation?

TL3414AIPG4 supports rail-to-rail output swing only under light loads (RL > 2 kΩ); under 70 mA load, output swing is 3.2 V (5 V supply) or 6.7 V (8.6 V supply), i.e., not rail-to-rail. Input common-mode range extends from VCC− to VCC+ − 2 V - not rail-to-rail, but sufficient to accept 0–3 V signals in 5 V systems. Neither input nor output is fully rail-to-rail.
