Texas Instruments TL071HIDR

Overview

TL071HIDR from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 20 V/μs slew rate, 1 mV typical input offset voltage, 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 (0.00012% THD+N) and high CMRR (105 dB) are critical.

For engineers reviewing the TL071HIDR datasheet, TL071HIDR pinout, TL071HIDR application, or TL071HIDR equivalent, key selection considerations include its FET-input architecture enabling pA-level bias current, wide supply flexibility, integrated EMI filtering, and guaranteed operation from –40°C to +125°C - all in an industry-standard SOIC-8 package.

Technical Context

The TL071HIDR employs a JFET differential input stage with cascode gain architecture, delivering high open-loop gain (125 dB) and 5.25 MHz gain-bandwidth product. Its input stage supports common-mode voltage up to VCC+, eliminating need for level-shifting in high-side sensing.

It integrates on-die EMI/RF filters and achieves 1.5 kV HBM ESD rating. The device features output short-circuit protection and stable operation with capacitive loads up to 300 pF without external compensation.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-noise JFET-input op-amp applications.

Compared with TL071CDR, TL071HIDR offers tighter offset, wider temperature range, and superior EMI immunity - making it suitable for rugged industrial use; versus OPA1641AIDR, it trades lower noise and rail-to-rail output for significantly lower power and broader supply flexibility.

Availability

TL071HIDR is available at Aetrix Electronics and suitable for pro audio mixer design, battery test equipment development, solar inverter string monitoring, and AC motor drive feedback circuits requiring stable component supply across extended temperature and EMI-prone environments.

Supply support for TL071HIDR includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Texas Instruments is a global semiconductor leader specializing in analog, embedded processing, and connectivity technologies, with decades of heritage in precision op-amps and industrial-grade signal chain solutions.

The TL07xH family was designed specifically for demanding industrial, automotive, and professional audio applications requiring low noise, high slew rate, extended temperature operation, and robust EMI performance - succeeding the legacy TL07x series with process and packaging enhancements.

FAQ

What is the maximum capacitive load the TL071HIDR can drive stably?

The TL071HIDR is characterized for stable operation with capacitive loads up to 300 pF without external compensation. This capability simplifies design in applications such as active filters and buffered DAC outputs where moderate capacitance is present on the output node. For loads exceeding 300 pF, isolation resistor or feedback capacitor compensation may be required to maintain phase margin above 56°.

Does the TL071HIDR support single-supply operation?

Yes, the TL071HIDR supports true single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing input signals referenced to the positive rail - a key advantage over many older op-amps. However, output swing does not reach the rails: minimum headroom is ~105 mV from VCC– and ~115 mV from VCC+ under 10 kΩ load.

How does the TL071HIDR differ from the standard TL071CDR?

The TL071HIDR uses a newer die fabrication process delivering improved specifications: lower typical input offset voltage (±1 mV vs ±3 mV), lower input voltage noise (37 nV/√Hz vs same but with higher max), higher ESD rating (1.5 kV HBM vs 2 kV HBM), and guaranteed operation from –40°C to +125°C (vs 0°C to 70°C). It also includes integrated EMI/RF filters absent in the C-grade part.

Is the TL071HIDR pin-compatible with other TL071 variants in SOIC-8?

Yes, TL071HIDR is fully pin-compatible with all TL071x variants in the D (SOIC-8) package, including TL071CDR, TL071ACDR, and TL071BCDR. Pin functions - IN– (2), IN+ (3), VCC– (4), OUT (6), VCC+ (7) - are identical. NC pins (1, 5, 8) are consistent across all versions and must remain unconnected.

What is the typical quiescent current of the TL071HIDR at ±15 V supply?

At ±15 V supply (VS = 30 V), the TL071HIDR draws 960–1156 µA typical quiescent current per amplifier, as specified in Section 5.7 of the datasheet. This value increases slightly with temperature, reaching up to 1160 µA at +125°C. The low IQ enables efficient use in portable or thermally constrained instrumentation designs.
