Product details
Overview
TL071HIDCKR from Texas Instruments is a single-channel, low-noise, JFET-input operational amplifier in a 5-pin SC70 package. 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 supply range, and operates across –40°C to +125°C for rugged industrial signal conditioning.
For engineers reviewing the TL071HIDCKR datasheet, TL071HIDCKR pinout, TL071HIDCKR application, or TL071HIDCKR equivalent, this page provides verified electrical specs, SC70 pin mapping, real-world use cases in pro audio and motor control, and validated alternative options with documented functional and thermal differences.
Technical Context
The TL071HIDCKR uses a high-impedance JFET differential input stage enabling ultra-low input bias current (±1 pA typ) and wide common-mode range extending to VCC+. Its internal compensation ensures stable unity-gain operation with up to 300 pF capacitive load drive and 56° phase margin.
It features integrated EMI/RF filters and 2-kV HBM ESD protection, supporting reliable operation in electrically noisy environments such as solar inverters and servo drive feedback loops without external filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables clean amplification of fast transients in audio and control loop signals without distortion |
| Input Offset Voltage | ±1 mV (typ) - supports precision DC-coupled gain stages with <0.1% error at 1 V output |
| Input Voltage Noise | 37 nV/√Hz @ 1 kHz - preserves signal integrity in low-level sensor interfaces and microphone preamps |
| Supply Voltage Range | ±2.25 V to ±20 V (4.5 V to 40 V) - compatible with dual-rail industrial supplies and single-supply systems using virtual ground |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor drives, and outdoor energy systems |
| Quiescent Current | 940 μA/ch (typ) - allows battery-powered instrumentation and always-on monitoring circuits with low standby power |
| CMRR | 105 dB (typ) - rejects common-mode interference in noisy plant-floor environments |
Pinout & Package
TL071HIDCKR is housed in a 5-pin SC70 (DCK) package - compact (2.0 mm × 1.25 mm), surface-mount, thermally efficient for space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN+ | Noninverting input - high-impedance (≥1 TΩ) node for reference or sensor signal routing |
| 2 | VCC– | Negative supply rail - must be decoupled locally to minimize ground bounce in multi-amplifier layouts |
| 3 | IN– | Inverting input - used for feedback network connection in standard op-amp configurations |
| 4 | OUT | Amplified output - capable of sourcing/sinking ±26 mA and driving ≥300 pF directly |
| 5 | VCC+ | Positive supply rail - accepts up to 40 V total supply swing; requires local 0.1 μF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical - eliminates significant DC error in high-impedance photodiode or piezoelectric sensor interfaces |
| Output Short-Circuit Protection | Internally limited to ±26 mA - prevents latch-up or destruction during accidental output shorts in field-deployed equipment |
| EMI/RF Filter Integration | On-die filtering - reduces need for external ferrite beads or RC snubbers in RF-prone industrial enclosures |
| Common-Mode Input to VCC+ | Supports rail-to-rail input beyond positive rail - enables direct sensing of signals referenced to VCC+ (e.g., high-side current sense) |
| Low THD+N | 0.00012% @ 1 kHz - meets fidelity requirements in professional audio mixer channel strips and studio-grade line drivers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CDCKR | Same SC70 package but commercial-grade (0°C to 70°C); higher max offset (±10 mV) and no EMI filter | Limited to benign environments like consumer audio or lab bench instruments | Select when cost sensitivity outweighs extended temp or EMI robustness needs |
| OPA1641AIDCKR | Lower noise (11 nV/√Hz), rail-to-rail output, higher quiescent current (1.3 mA), same SC70 footprint | Better suited for ultra-low-noise audio DAC output stages; not drop-in due to different biasing and output swing | Choose when THD+N <0.00005% and wider dynamic range are critical, and layout can accommodate revised decoupling |
Compared with TL071CDCKR, TL071HIDCKR adds 85°C wider operating range and integrated EMI rejection-critical for factory-floor deployment; versus OPA1641AIDCKR, it trades 3× higher noise for 2.5× lower supply current and proven ruggedness in high-voltage industrial feedback loops.

FAQ
What is the maximum capacitive load the TL071HIDCKR can drive without oscillation?
The TL071HIDCKR is specified to drive up to 300 pF capacitive load while maintaining 56° phase margin and stable unity-gain operation. This capability eliminates the need for isolation resistors in many sensor interface and cable-driving applications, though layout-dependent parasitics should be minimized for consistent performance.
Does the TL071HIDCKR support single-supply operation?
Yes, the TL071HIDCKR supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing inputs to swing up to the positive rail-ideal for single-supply configurations with properly biased input networks and rail-to-rail output stages downstream.
How does the TL071HIDCKR's ESD rating compare to older TL071 variants?
The TL071HIDCKR features 2-kV HBM ESD rating per ANSI/ESDA/JEDEC JS-001-significantly improved over legacy TL071C (1.5-kV HBM). This enhanced robustness reduces field failures during handling and assembly in high-volume manufacturing environments.
Can the TL071HIDCKR replace TL071CP in existing SOIC-8 designs?
No-the TL071HIDCKR uses a 5-pin SC70 package and is not pin-compatible with the 8-pin SOIC TL071CP. Direct replacement would require PCB redesign. For drop-in upgrades, consider TL071HIDR (SOIC-8) instead, which shares identical electrical specs and temperature range.
What is the typical input bias current of the TL071HIDCKR at 125°C?
Per TI's characterization data, the TL071HIDCKR exhibits ≤5 nA input bias current across –40°C to +125°C. At 125°C, typical IB remains below 2 nA-enabling accurate high-impedance measurements in hot industrial enclosures without significant leakage-induced offset.
