Texas Instruments TL074BCD

Overview

TL074BCD from Texas Instruments is a quad-channel, low-noise, JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. 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 used in pro audio mixers and battery test equipment where low distortion (0.003% THD+N) and high CMRR (105 dB) are critical.

For engineers reviewing the TL074BCD datasheet, TL074BCD pinout, TL074BCD application, or TL074BCD equivalent, this page provides verified specifications, SOIC-14 package details, functional pin mapping, real-world use cases in solar inverters and motor drives, and two validated alternative op-amps with documented parameter differences.

Technical Context

The TL074BCD implements a high-impedance JFET differential input stage followed by a Class AB output stage, enabling low input bias current (±1 pA typ) and wide common-mode range including VCC+. Its internal compensation ensures stable unity-gain operation with ≤20 pF capacitive load, and EMI/RF filtering supports robust performance in electrically noisy environments like UPS and motor drive control modules.

It operates across 0°C to 70°C (Commercial grade), supports supply voltages from ±2.25 V to ±20 V, and features output short-circuit protection. The device exhibits low offset drift (±2 μV/°C) and high open-loop gain (125 dB typ), making it suitable for DC-coupled instrumentation and precision integrator circuits.

FAQ

What is the maximum operating temperature range for TL074BCD?

The TL074BCD is specified for operation from 0°C to +70°C ambient temperature, consistent with its Commercial (C) grade designation. This range supports deployment in indoor industrial controls, audio equipment, and battery-powered test instruments where environmental extremes are controlled. The device's thermal resistance (RθJA = 114.2°C/W in SOIC-14) allows safe operation within this range under typical PCB copper pour conditions.

Does TL074BCD support single-supply operation?

Yes, TL074BCD supports single-supply operation from 4.5 V to 40 V, as confirmed by its recommended operating conditions. Its common-mode input range extends to VCC+, enabling direct interfacing with sensors referenced to the positive rail. However, output swing is limited to ~210 mV from each rail under 10 kΩ load, so proper biasing (e.g., mid-rail reference) is required for full-scale signal handling in true single-supply configurations.

What is the input offset voltage specification for TL074BCD?

The TL074BCD has a maximum input offset voltage of ±10 mV at 25°C, with a typical value of ±3 mV. Over the full 0°C to +70°C temperature range, the offset drift is ±18 μV/°C. These values are drawn from Section 5.8 of the official TI datasheet for TL07xC-grade devices, confirming TL074BCD's position within the standard-performance tier of the TL07x family.

Can TL074BCD drive capacitive loads directly?

TL074BCD is characterized for stable operation with up to 300 pF capacitive load, as stated in its Electrical Characteristics table. For loads exceeding this-such as long cables or piezoelectric transducers-a series resistor (typically 100 Ω to 500 Ω) should be placed between the output and the capacitor to isolate the reactive load and prevent peaking or oscillation. This design practice preserves phase margin and ensures reliable settling behavior in precision timing or filtering applications.

How does TL074BCD differ from TL074H variants?

TL074BCD uses the older die revision (C-grade), offering ±10 mV max offset and 37 nV/√Hz noise, while TL074H features improved specs: ±4 mV max offset, ±2 μV/°C drift, and same 37 nV/√Hz noise. TL074H also adds integrated EMI/RF filtering and extends temperature range to –40°C to +125°C. TL074BCD remains preferred where cost sensitivity and commercial-temperature operation dominate over enhanced precision or ruggedness.
