Product details
Overview
TL071HIDBVR from Texas Instruments is a single-channel, low-noise, JFET-input operational amplifier optimized for high-fidelity 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 widely used in pro audio mixers and battery test equipment where low distortion and wide dynamic range are critical.
For engineers reviewing the TL071HIDBVR datasheet, TL071HIDBVR pinout, TL071HIDBVR application, or TL071HIDBVR equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±1 pA typ), high CMRR (105 dB), integrated EMI/RF filtering, and guaranteed operation from –40°C to +125°C - all in a space-constrained 5-pin SOT-23 package.
Technical Context
The TL071HIDBVR implements a JFET differential input stage with high-impedance, low-noise characteristics, enabling direct coupling of high-impedance sensors and microphone preamplifier stages. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It features rail-inclusive common-mode input range (VCC– to VCC+), output short-circuit protection, and ESD robustness (±2 kV HBM). The device operates across ±2.25 V to ±20 V supplies and maintains low THD+N (0.00012% typ) at 1 kHz, making it suitable for AC-coupled and DC-coupled precision amplification paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables accurate reproduction of fast transients in audio and test signal paths without slew-induced distortion |
| Input Offset Voltage | ±1 mV (typ) - minimizes DC error in precision gain stages and sensor front-ends |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level signals in instrumentation |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended) - accommodates both low-voltage portable and high-dynamic-range industrial rails |
| Common-Mode Input Range | Includes VCC+ - allows direct interface with signals referenced to positive supply, simplifying level-shifting circuits |
| Quiescent Current | 940 μA/ch (typ) - balances low power consumption with high-speed performance for battery-powered designs |

Pinout & Package
TL071HIDBVR is housed in a 5-pin SOT-23 (DBV) package - compact, surface-mount, and optimized for automated assembly in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - drives downstream stages or feedback networks; capable of sourcing/sinking ±26 mA |
| 2 | VCC– | Negative supply rail - must be decoupled locally to minimize noise coupling into high-impedance inputs |
| 3 | IN+ | Noninverting input - high-impedance (6 TΩ || 1 pF) node; sensitive to layout parasitics and EMI |
| 4 | IN– | Inverting input - accepts feedback and signal paths; matched impedance required for optimal CMRR |
| 5 | VCC+ | Positive supply rail - powers internal JFET and bipolar circuitry; requires local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA (typ) - preserves signal integrity in high-source-impedance applications like piezoelectric sensors and photodiode transimpedance amps |
| Integrated EMI/RF Filters | On-chip filtering suppresses RF rectification and demodulation artifacts in noisy industrial environments |
| Wide Temperature Range | –40°C to +125°C operation - qualified for under-hood automotive, solar inverter, and industrial motor drive control modules |
| Output Short-Circuit Protection | Self-limiting current prevents latch-up or destruction during fault conditions, enhancing system reliability |
| High PSRR & CMRR | 105 dB PSRR and CMRR - rejects supply ripple and common-mode interference in mixed-signal systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CDR | Standard TL071 (non-H suffix); wider offset (±3 mV max), lower ESD rating (±1.5 kV HBM), –40°C to +85°C temp range | Cost-sensitive consumer audio and general-purpose analog circuits where extended temperature and EMI immunity are not required | Select when full TL071H performance is unnecessary and legacy compatibility or lower cost is prioritized |
| OPA1671IDBVR | Lower noise (1.3 nV/√Hz), rail-to-rail output, higher quiescent current (1.6 mA), ±2.25 V to ±18 V supply | Ultra-high-fidelity audio preamps and low-distortion instrumentation requiring superior noise floor and output swing | Choose when noise performance dominates over power budget and legacy TL07x footprint compatibility is not mandatory |
Compared with TL071CDR, TL071HIDBVR offers tighter offset, higher ESD robustness, and extended temperature capability - critical for industrial deployments; versus OPA1671IDBVR, it trades noise performance for lower power and broader supply flexibility, maintaining proven TL07x topology familiarity.

FAQ
What is the maximum supply voltage for TL071HIDBVR?
The TL071HIDBVR supports a total supply voltage (VCC+ – VCC–) from ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended). Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operating conditions limit continuous use to 40 V to ensure long-term reliability and specified performance across temperature.
Does TL071HIDBVR have rail-to-rail input or output capability?
TL071HIDBVR features rail-to-rail common-mode input range - its inputs operate from VCC– to VCC+, including the positive rail. However, its output swing is not rail-to-rail: typical headroom is 115–210 mV from each rail under 10 kΩ load. For true rail-to-rail output, consider alternatives like OPA1671IDBVR.
Can TL071HIDBVR drive capacitive loads?
Yes - TL071HIDBVR is characterized to drive capacitive loads up to 300 pF while maintaining stability. This capability supports direct connection to ADC input filters and cable-driven outputs. For loads >300 pF, external isolation resistance or feedback compensation is recommended per TI's application notes.
What is the input bias current specification for TL071HIDBVR at 125°C?
At TA = –40°C to +125°C, the input bias current for TL071HIDBVR is specified at ±5 nA maximum (per datasheet Section 5.7). This elevated value reflects JFET gate leakage increase at high temperature and remains significantly lower than bipolar-input op-amps, preserving high-impedance node integrity.
Is TL071HIDBVR pin-compatible with older TL071 variants in SOT-23?
Yes - TL071HIDBVR uses the standard 5-pin SOT-23 (DBV) pinout shared with TL071CDR, TL071ACDR, and TL071BCDR. Pin 1 is OUT, Pin 2 is VCC–, Pin 3 is IN+, Pin 4 is IN–, and Pin 5 is VCC+. No PCB layout changes are required when upgrading from legacy TL071 variants in DBV package.
