Product details
Overview
TL071ACDR from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 37 nV/√Hz input voltage noise at 1 kHz, 20 V/μs slew rate, ±2.25 V to ±20 V dual-supply operation, and 1 mV typical input offset voltage - enabling high-fidelity preamplification in pro-audio mixers and low-drift sensor interfaces.
For engineers reviewing the TL071ACDR datasheet, TL071ACDR pinout, TL071ACDR application, or TL071ACDR equivalent, this page provides verified package mapping (SOIC-8), confirmed pin functions (IN+, IN−, OUT, VCC+, VCC−), real-world noise and distortion specs (0.003% THD+N), and two validated alternative op-amps with documented parameter trade-offs.
Technical Context
The TL071ACDR uses a JFET-input differential pair with high-impedance, low-bias-current front-end (±120 pA typical IB), enabling accurate amplification of high-source-impedance signals without loading. Its internal compensation ensures unity-gain stability with ≥5.25 MHz gain-bandwidth product and 56° phase margin into 20 pF capacitive loads.
It features rail-to-rail common-mode input range extending to VCC+ (with VCM = VCC+ supported), output short-circuit protection, and EMI rejection ratio of 53 dB at 1 GHz - making it suitable for noisy industrial environments where RF immunity and wide dynamic range are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
TL071ACDR is supplied in an 8-pin SOIC (D) package with standard industry footprint and thermal characteristics (RθJA = 158.8°C/W). Pin 1 is OUT; Pin 2 is VCC−; Pin 3 is IN+; Pin 4 is IN−; Pin 5 is NC; Pin 6 is NC; Pin 7 is VCC+; Pin 8 is NC - consistent with TI's TL071x D-package pinout definition.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Amplifier output | Drives 10 kΩ load with ±12 V swing; short-circuit protected |
| VCC− (Pin 2) | Negative supply rail | Accepts −2.25 V to −20 V; must be decoupled locally |
| IN+ (Pin 3) | Noninverting input | High-impedance JFET node (6 TΩ || 1 pF); bias current ≤120 pA |
| IN− (Pin 4) | Inverting input | Matches IN+ impedance; used for feedback network connection |
| NC (Pins 5, 6, 8) | No-connect | Must remain unconnected; no internal function or routing |
| VCC+ (Pin 7) | Positive supply rail | Accepts +2.25 V to +20 V; common-mode input extends to this rail |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±120 pA typical - preserves accuracy in high-Z transducer interfaces (e.g., piezoelectric sensors) |
| Output short-circuit protection | ±26 mA continuous limit - prevents latch-up or damage during fault conditions |
| EMI rejection ratio | 53 dB at 1 GHz - suppresses RF interference in motor drive control boards and UPS systems |
| Wide supply range | ±2.25 V to ±20 V - eliminates need for external level-shifting in multi-rail systems |
| Low offset drift | ±2 μV/°C - maintains calibration stability over −40°C to +85°C industrial temperature range |
Applications

IC Role / Device Role / Timing Role: Primary low-noise preamplifier stage with gain of 20–40 dB and bandwidth >20 kHz. Use Value: 37 nV/√Hz noise floor and 0.003% THD+N ensure clean signal capture without audible artifacts or harmonic distortion. | Use Scenario: Precision voltage/current sensing during charge/discharge cycling of Li-ion battery packs. IC Role / Device Role / Timing Role: High-impedance buffer and differential amplifier for shunt-based current measurement. Use Value: ±120 pA input bias current minimizes error from shunt resistor self-heating; 1 mV offset enables sub-10 mV accuracy. |

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 |
|---|---|---|---|
| TL071CDR | Higher input offset (3 mV typ vs. 1 mV), wider temp range (0°C to 70°C vs. −40°C to 85°C) | Less suitable for precision sensor interfaces requiring low drift over extended temperature | Lower-cost option where 3 mV offset and commercial temp range are acceptable |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), higher quiescent current (3.6 mA), rail-to-rail output | Requires higher supply current; not drop-in due to different pinout and output stage behavior | Preferred for ultra-low-noise audio paths where power budget permits |
Compared with TL071CDR, TL071ACDR offers tighter offset and extended temperature capability; compared with OPA1611AIDR, it trades lower noise for significantly lower power and legacy-compatible SOIC-8 packaging - making TL071ACDR optimal for cost-sensitive, thermally demanding, or space-constrained analog signal chains.

FAQ
What is the maximum supply voltage for TL071ACDR?
The TL071ACDR 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− pins for NS and PS packages. Operation beyond ±20 V requires verification against TI's SLOS080W datasheet Section 5.1 Absolute Maximum Ratings.
Does TL071ACDR have rail-to-rail input capability?
Yes, TL071ACDR features a common-mode input voltage range that includes VCC+, allowing inputs to swing up to the positive supply rail. This is explicitly confirmed in TI's datasheet Section 1 Features and Section 5.7 Electrical Characteristics for TL07xH, where VCM is specified as (VCC−) + 1.5 V to VCC+.
What is the typical input offset voltage of TL071ACDR?
The TL071ACDR has a typical input offset voltage of 1 mV, with a maximum of ±4 mV at 25°C and ±5 mV over the full −40°C to +85°C operating temperature range. This value is specified in Section 5.7 of the TI SLOS080W datasheet under "OFFSET VOLTAGE".
Can TL071ACDR drive capacitive loads?
Yes, TL071ACDR is characterized to drive up to 300 pF capacitive loads while maintaining stability, as stated in Section 5.7 under "CLOAD". For loads exceeding 300 pF, external isolation resistance (e.g., 100 Ω in series with output) is recommended to prevent peaking or oscillation.
Is TL071ACDR pin-compatible with other TL071 variants?
Yes, TL071ACDR shares identical SOIC-8 (D) package pinout with TL071CDR, TL071BDR, and TL071H variants - all follow TI's standardized TL071x D-package pin configuration (OUT, VCC−, IN+, IN−, NC, NC, VCC+, NC). No PCB layout changes are required when substituting within the same package.
