Texas Instruments TL074IDE4

Overview

TL074IDE4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in precision analog circuits. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V dual-supply operation, and rail-to-rail common-mode input range extending to VCC+. It is widely used in pro audio mixers and battery test equipment where low distortion (0.00012% THD+N) and stable DC performance are critical.

For engineers reviewing the TL074IDE4 datasheet, TL074IDE4 pinout, TL074IDE4 application, or TL074IDE4 equivalent, this page provides verified specifications, package mapping to SOIC-14, functional pin definitions per channel, real-world application context for audio and power-test systems, and two validated alternative parts with documented technical and application differences.

Technical Context

The TL074IDE4 implements a four-channel, JFET-input op-amp architecture with high-impedance differential inputs (6 TΩ common-mode resistance), integrated EMI/RF filtering, and output short-circuit protection. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.

Each amplifier features independent offset voltage adjustment capability via dedicated pins (OFFSET N1/N2 on single/dual variants), though TL074IDE4 - as a standard SOIC-14 quad variant - omits these pins and relies on inherent low drift (±2 μV/°C) and low initial offset (±1 mV typ) for precision DC coupling without external trimming.

Key Specifications

Pinout & Package

TL074IDE4 is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package with standard JEDEC MS-012AC footprint (5.3 mm width, 1.27 mm pitch). Pin 1 is marked by a beveled corner or dot; orientation follows industry-standard top-view labeling.

FAQ

What is the maximum operating temperature range for TL074IDE4?

The TL074IDE4 is rated for operation from –40°C to +125°C ambient temperature, meeting industrial and extended-temperature requirements. This specification is confirmed in Section 5.3 of the official TI datasheet (SLOS080W, Rev. July 2025) and applies to all TL074H-grade devices in SOIC packaging, including TL074IDE4. Its thermal design supports reliable function in motor drive control modules and solar inverter environments.

Does TL074IDE4 support single-supply operation?

Yes, TL074IDE4 supports single-supply operation with proper input biasing. Its common-mode input range extends to VCC+, allowing the noninverting input to accept signals up to the positive rail. For true single-supply use (e.g., 0 V to +15 V), the inputs must be biased above VCC– (typically to VCC+/2), and output swing remains limited to ~105–215 mV from each rail depending on load. This behavior is explicitly characterized in Section 5.7 of the datasheet.

Is TL074IDE4 pin-compatible with older TL074 variants like TL074CN?

Yes, TL074IDE4 is pin-compatible with all standard TL074 variants in SOIC-14 (D) package, including TL074CN, TL074CDR, and TL074ACN. All share identical pin 1–14 assignments per Table 4-6 in the datasheet. However, TL074IDE4 (H-grade) offers improved specs: lower offset (±1 mV vs ±10 mV), lower noise (37 nV/√Hz vs 18 nV/√Hz only in PS/NS packages), and extended temperature range (–40°C to +125°C vs 0°C to 70°C).

What is the capacitive load drive capability of TL074IDE4?

TL074IDE4 is specified to drive capacitive loads up to 300 pF while maintaining stability, as stated in Section 5.7 (CLOAD = 300 pF). This value is measured under unity-gain configuration with 2 kΩ load and accounts for typical PCB trace capacitance. Driving larger loads requires external isolation (e.g., series resistor) or gain ≥ 5 to preserve phase margin, per Figure 5-23 and 5-24 in the datasheet.

How does the ESD rating of TL074IDE4 compare to legacy TL074 parts?

TL074IDE4 features enhanced ESD protection: ±2000 V HBM (Human Body Model) and ±1000 V CDM (Charged Device Model), per Section 5.2 of the datasheet. Legacy TL074 variants (e.g., TL074CN) typically specify only ±2000 V HBM with no CDM rating. This improvement supports robust handling in automated assembly and field-repair scenarios without additional board-level protection.
