Texas Instruments TL074BCDRE4

Overview

TL074BCDRE4 from Texas Instruments is a quad-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. 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 deployed in pro audio mixers and battery test equipment where high fidelity and DC accuracy are critical.

For engineers reviewing the TL074BCDRE4 datasheet, TL074BCDRE4 pinout, TL074BCDRE4 application, or TL074BCDRE4 equivalent, this page provides verified specifications, package-validated pin functions, real-world use cases, and two confirmed alternative parts with documented technical and application differences - all aligned to the TL074BCDRE4's C-grade temperature range (0°C to 70°C) and SOIC-14 packaging.

Technical Context

The TL074BCDRE4 implements a high-swing, low-noise JFET-input stage with fully differential output buffering, enabling stable unity-gain operation and fast overload recovery (300 ns). Its input stage supports common-mode voltages up to VCC+, eliminating level-shifting requirements in single-supply configurations when biased appropriately.

It features integrated EMI filtering and 2 kV HBM ESD protection, with quiescent current of 1.4–2.5 mA per amplifier at ±15 V. The device operates across 0°C to 70°C (C-grade), distinguishing it from H- and M-grade variants with extended temperature ranges.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature range for TL074BCDRE4?

The TL074BCDRE4 is rated for operation from 0°C to 70°C (industrial C-grade). This differs from TL074H (–40°C to +125°C) and TL074M (–55°C to +125°C) variants. Always verify ambient and junction temperature margins using the 114.2°C/W RθJA value for SOIC-14 packages under actual PCB layout and airflow conditions. Thermal derating is required above 70°C ambient.

Does TL074BCDRE4 support single-supply operation?

Yes, TL074BCDRE4 supports single-supply operation due to its common-mode input voltage range extending to VCC+. When operated from a single 15 V rail, the inputs can accept signals from ground up to 15 V, provided the output load is biased appropriately (e.g., AC-coupled or referenced to mid-rail). Output swing remains limited to ~12 V peak-to-peak into 10 kΩ.

What is the input offset voltage specification for TL074BCDRE4?

TL074BCDRE4 has a maximum input offset voltage of 10 mV at 25°C (typical 3 mV), per the TL07xC family specification in Section 5.8 of the datasheet. This applies across the full 0°C to 70°C temperature range, with drift up to ±18 µV/°C. For applications requiring tighter offset, consider TL074ACDRE4 (6 mV max) or auto-zero alternatives.

Can TL074BCDRE4 drive capacitive loads directly?

TL074BCDRE4 is characterized for stable operation with up to 300 pF capacitive load, per Section 5.7. Driving larger loads (e.g., >500 pF) risks peaking or oscillation; use series resistance (20–100 Ω) between output and load, or add a small isolation resistor (10–50 Ω) with local bypass capacitance to maintain phase margin. Avoid direct connection to long cables or unbuffered ADC inputs without verification.

Is TL074BCDRE4 pin-compatible with other TL074 variants?

Yes, TL074BCDRE4 is pin-compatible with all TL074x variants in SOIC-14 packaging (e.g., TL074CDR, TL074ACDR, TL074BCDR). Pin functions match Table 4-6 exactly: pins 1/7/8/9/14 are outputs/inputs/supplies as defined. However, electrical performance (noise, offset, EMI rejection) differs across B/A/C/H/M grades - always validate against your specific design requirements.
