Product details
Overview
TL071BCDR from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for low-noise audio and precision 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 1 mV typical input offset voltage. It is widely used in pro-audio mixers and battery test equipment where high CMRR and rail-inclusive common-mode range are critical.
For engineers reviewing the TL071BCDR datasheet, TL071BCDR pinout, TL071BCDR application, or TL071BCDR equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±1 pA typ), wide supply flexibility, output short-circuit protection, and compatibility with SOIC-8 PCB footprints in industrial and audio signal chains.
Technical Context
The TL071BCDR uses a high-voltage, dielectrically isolated JFET input stage enabling femtoampere-level input bias currents and excellent common-mode rejection. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF, and the output stage provides symmetrical sourcing/sinking capability with rail-to-rail input voltage range extending to VCC+.
Designed for cost-sensitive yet performance-critical analog signal paths, it integrates EMI/RF filtering and achieves 125 dB open-loop gain with 5.25 MHz gain-bandwidth product - making it suitable for active filters, transimpedance amplifiers, and DC-coupled instrumentation front-ends operating across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables faithful reproduction of fast transient signals in audio and control loops without slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - supports low-noise preamplification in microphone and sensor interfaces |
| Input Offset Voltage | ±1 mV (typ) - reduces DC error in precision integrators and differential amplifiers |
| Supply Voltage Range | ±2.25 V to ±20 V - accommodates both low-power portable systems and high-dynamic-range industrial supplies |
| Common-Mode Input Range | Includes VCC+ - allows direct sensing of signals referenced to positive rail, e.g., high-side current monitoring |
| Quiescent Current | 940 μA/ch (typ) - balances low power consumption with high-speed performance in always-on analog stages |
| Open-Loop Gain | 125 dB - ensures high closed-loop accuracy and minimal gain error in precision gain blocks |
Pinout & Package
TL071BCDR is housed in an 8-pin SOIC (D) package with standard industry footprint and thermal characteristics (RθJA = 158.8°C/W). The device features no internal offset null pins in this variant - consistent with the 'B' grade and SOIC packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output | Amplified signal output; capable of ±26 mA short-circuit current and 210 mV headroom from positive rail (RL = 10 kΩ) |
| 2 | Inverting Input | High-impedance FET node; bias current ≤ ±1 pA (typ) minimizes resistor-induced errors in high-Z networks |
| 3 | Noninverting Input | High-impedance FET node; common-mode range extends to VCC+, enabling rail-referenced sensing |
| 4 | VCC– | Negative supply connection; supports split or single-supply operation down to –2.25 V |
| 5 | No Connect | Unused terminal; must remain unconnected per TI specification for SOIC-8 TL071B variants |
| 6 | Output | Not applicable - TL071BCDR is single-channel; pin 6 is NC in this package configuration |
| 7 | VCC+ | Positive supply connection; accepts up to +20 V, enabling wide dynamic range signal processing |
| 8 | No Connect | Unused terminal; electrically isolated and not bonded internally in SOIC-8 D package |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CDR | Higher input offset voltage (±3 mV max vs ±1 mV max), wider temp range (0°C to 70°C vs –40°C to 125°C) | Less suited for precision DC-coupled systems requiring long-term drift stability | Select TL071CDR only for cost-sensitive commercial-grade audio or non-critical signal buffering |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), higher quiescent current (3.6 mA), rail-to-rail output, no short-circuit protection | Preferred for ultra-low-noise studio-grade preamps but unsuitable for rugged industrial feedback loops | Choose OPA1611AIDR when noise dominates design priority and output fault tolerance is managed externally |
Compared with TL071CDR and OPA1611AIDR, TL071BCDR uniquely balances low noise, wide temperature operation, short-circuit resilience, and cost-making it optimal for industrial audio and battery test systems where reliability and DC precision coexist.

FAQ
What is the maximum supply voltage for TL071BCDR?
The TL071BCDR supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V), with absolute maximum ratings of –0.3 V to +36 V on VCC+ and VCC– for NS/PS packages. Operation beyond ±20 V requires verification against derating curves in the datasheet's thermal tables.
Does TL071BCDR have offset null pins?
No, TL071BCDR in the SOIC-8 (D) package does not include offset null pins. Pin 1 and Pin 5 are designated as NC (no connect) per TI's pin function table for TL071C/TL071B variants in D and P packages - offset adjustment is not supported in this configuration.
Is TL071BCDR suitable for single-supply operation?
Yes, TL071BCDR supports single-supply operation with VCC– grounded and VCC+ between 4.5 V and 40 V. Its common-mode input range includes VCC+, allowing input signals up to the positive rail - ideal for sensors referenced to VCC+ in 3.3 V or 5 V systems.
What is the input bias current specification for TL071BCDR?
The TL071BCDR exhibits a typical input bias current of ±1 pA at 25°C, with a maximum of ±120 pA over full temperature range (–40°C to +125°C). This ultra-low value stems from its JFET input stage and enables use with megaohm-level feedback and source impedances without significant DC error.
How does TL071BCDR compare to TL071H in noise performance?
TL071BCDR and TL071H share identical noise specifications: 37 nV/√Hz input voltage noise density at 1 kHz and 1.4 µVRMS integrated 0.1 Hz–10 Hz noise. Both belong to the same core TL07x family die; the 'H' suffix denotes newer process revision with enhanced ESD (1.5 kV HBM) and extended temperature range, while 'B' denotes initial precision grade.
