Texas Instruments TL3414AIPW

Overview

TL3414AIPW 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 voltage 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 TL3414AIPW datasheet, TL3414AIPW pinout, TL3414AIPW application, or TL3414AIPW equivalent, key selection criteria include output current capability under load, rail-to-rail input common-mode range (VCC− to VCC+ − 2 V), thermal performance in TSSOP-8 (θJA = 149°C/W), and compatibility with low-cost audio signal conditioning stages requiring minimal external components.

Technical Context

The TL3414AIPW integrates two independent high-output-current op-amps in a single TSSOP-8 package, supporting both single-supply (3–15 V) and dual-supply (±1.5 V to ±7.5 V) operation. Its internal architecture delivers 100 dB large-signal voltage gain and 79 dB common-mode rejection at 25°C, with input bias current under 600 nA and input offset voltage ≤5 mV.

It features rail-to-rail input stage operation (VICR = VCC− to VCC+ − 2 V) and robust output swing: 3.2 V into 70 mA load at 5 V supply, and 6.7 V into 70 mA at 8.6 V supply. Slew rate increases from 0.83 V/µs (5 V) to 1.3 V/µs (8.6 V), confirming supply-dependent dynamic performance scaling.

FAQ

What is the maximum output current capability of the TL3414AIPW per channel?

The TL3414AIPW delivers up to 70 mA per amplifier channel into resistive loads, verified at both 5 V and 8.6 V supply voltages. This rating applies under continuous DC conditions with proper PCB thermal relief and ambient temperature ≤85°C. The device sustains this current without foldback or thermal shutdown in typical TSSOP-8 layouts with ≥1 in² copper pour.

Can the TL3414AIPW operate from a single 3.3 V supply?

Yes, the TL3414AIPW supports single-supply operation down to 3 V, making it compatible with 3.3 V systems. At 3.3 V, output swing is reduced (typically ≥1.8 V into high-Z load), and output current capability decreases proportionally. Full 70 mA drive requires ≥5 V supply; consult the "DC Electrical Characteristics" table in the SLOS453A datasheet for 3.3 V-specific performance limits.

Does the TL3414AIPW have rail-to-rail output capability?

No, the TL3414AIPW does not feature rail-to-rail output. Its output swing is specified as 3.2 V into 70 mA at 5 V supply (i.e., 1.8 V headroom from VCC+), and 6.7 V into 70 mA at 8.6 V supply (1.9 V headroom). The output can swing within ~1.8–2.0 V of either rail depending on load and supply, consistent with standard bipolar-output op-amp architecture.

What is the thermal resistance (θJA) of the TL3414AIPW in its TSSOP-8 package?

The TL3414AIPW has a junction-to-ambient thermal resistance (θJA) of 149°C/W in the TSSOP-8 (PW) package, measured per JEDEC JESD 51-7 standards on a 1-inch² FR-4 board with 2 oz copper. This value assumes standard 2-layer PCB layout with no internal copper planes; adding thermal vias and ground/power plane layers can reduce effective θJA by 20–30% in production designs.

Is the TL3414AIPW pin-compatible with other dual op-amps in TSSOP-8 packages?

The TL3414AIPW uses the industry-standard dual op-amp pinout (OUT1, IN1−, IN1+, VCC−, VCC+, IN2+, IN2−, OUT2), matching SOIC-8 and TSSOP-8 footprints for LM358, TLV2372, and similar devices. However, electrical differences - especially 70 mA output drive and wider supply range - mean functional substitution requires validation of load, supply, and thermal conditions; it is not a drop-in replacement for lower-drive op-amps.
