Texas Instruments TL074ID

Overview

TL074ID from Texas Instruments is a quad-channel, low-noise, JFET-input operational amplifier designed for precision analog signal conditioning in audio, instrumentation, and industrial control 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 widely used in pro audio mixers and battery test equipment where low distortion and high CMRR are critical.

For engineers reviewing the TL074ID datasheet, TL074ID pinout, TL074ID application, or TL074ID equivalent, key selection criteria include its FET-input architecture enabling ultra-low input bias current (±1 pA typ), wide supply range compatibility, quad-channel integration for space-constrained designs, and verified performance across –40°C to +125°C ambient temperature.

Technical Context

The TL074ID employs a high-impedance JFET differential input stage followed by a Class AB output stage, supporting stable unity-gain operation with capacitive loads up to 300 pF. Its internal compensation ensures phase margin of 56° at G = +1 with 10 kΩ load and 20 pF capacitance.

It features integrated EMI/RF filters and 2-kV HBM ESD protection, enabling robust operation in electrically noisy environments such as motor drive feedback loops and solar inverter sensor interfaces without external filtering.

FAQ

What is the maximum operating temperature range for TL074ID?

The TL074ID is specified for operation from –40°C to +125°C ambient temperature, matching the TL074H grade. This extended range supports deployment in industrial motor drives, solar inverters, and automotive under-hood electronics where thermal stress exceeds commercial-grade limits. The datasheet confirms this range under Recommended Operating Conditions section 5.3.

Does TL074ID support single-supply operation?

Yes, TL074ID supports single-supply operation with a minimum total supply voltage of 4.5 V and maximum of 40 V. Its common-mode input range extends to VCC+, allowing the noninverting input to accept signals up to the positive rail - a key enabler for single-supply sensor interfaces and active filters. This behavior is explicitly documented in the Electrical Characteristics table for VCM.

What is the input bias current specification for TL074ID at 125°C?

At TA = –40°C to +125°C, the TL074ID's input bias current is specified as ±5 nA maximum, per Section 5.7 of the datasheet. This elevated limit reflects JFET parameter shift at high temperature but remains orders of magnitude lower than bipolar-input op-amps, preserving accuracy in high-impedance circuits even under thermal stress.

Can TL074ID drive capacitive loads up to 300 pF without instability?

Yes, TL074ID is characterized to safely drive capacitive loads up to 300 pF while maintaining ≥56° phase margin at unity gain, as confirmed in the Electrical Characteristics table under CLOAD. This capability eliminates the need for external isolation resistors in many filter and cable-driving applications - a key advantage over earlier TL074 variants lacking this validation.

How does TL074ID differ from TL074CDR in terms of ESD robustness?

TL074ID features 2-kV HBM ESD rating per ANSI/ESDA/JEDEC JS-001, whereas TL074CDR is rated at 1.5-kV HBM. This 33% higher ESD tolerance makes TL074ID more resilient during automated PCB assembly and field service in electrostatic-prone environments such as factory floors and solar farm maintenance - a distinction clearly stated in Section 5.2 of the TL074xH datasheet.
