Product details
Overview
TL971QDRQ1 from Texas Instruments is a single-channel, rail-to-rail output operational amplifier qualified for automotive applications (AEC-Q100 Grade 1, –40°C to +125°C). It delivers 4 nV/√Hz input voltage noise, 12 MHz gain bandwidth, 5 V/μs slew rate, and ±2.4 V output swing at ±2.5 V supply - ideal for low-noise audio preamplification in battery-powered infotainment systems.
For engineers reviewing the TL971QDRQ1 datasheet, TL971QDRQ1 pinout, TL971QDRQ1 application, or TL971QDRQ1 equivalent, key selection considerations include its automotive-grade reliability, ultra-low distortion (0.003%), 2.7 V to 12 V single-supply operation, and SOIC-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TL971QDRQ1 employs a bipolar input stage optimized for low noise and low distortion, supporting rail-to-rail output swing without phase reversal. Its internal compensation ensures stability with capacitive loads up to 250 pF and maintains ≥60° phase margin across 2.7–12 V supply range.
It operates over full automotive temperature range with guaranteed input offset voltage ≤6 mV, CMRR ≥60 dB, and PSRR ≥60 dB - enabling direct sensor interface and high-fidelity signal conditioning in noisy vehicle environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - supports single-supply operation in 3.3 V and 5 V automotive domains, eliminating dual-rail design complexity. |
| Input Voltage Noise | 4 nV/√Hz at 100 kHz - enables clean amplification of weak microphone or piezoelectric sensor signals without audible hiss. |
| Gain Bandwidth Product | 12 MHz (typ) - supports stable unity-gain buffer configurations and closed-loop audio filters up to ~100 kHz. |
| Slew Rate | 5 V/μs (typ) - preserves transient fidelity in audio paths and prevents clipping on fast-rising control signals. |
| Output Swing | ±2.4 V at ±2.5 V supply - delivers >96% of rail-to-rail dynamic range, maximizing SNR in low-voltage ADC front-ends. |
| THD+N | 0.003% at 1 kHz - meets professional audio preamp requirements and minimizes harmonic artifacts in cabin audio systems. |
| ESD Protection | HBM: 2000 V, MM: 200 V, CDM: 1500 V - withstands handling and in-system ESD events common in automotive assembly and service environments. |
Pinout & Package
TL971QDRQ1 is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with 1.27 mm lead pitch, 3.9 mm × 4.9 mm body, and 1.75 mm max height. Pin 1 is located at the top-left corner adjacent to the notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - drives downstream ADC input, speaker driver, or active filter with rail-to-rail swing capability. |
| 2 | IN– | Inverting input - accepts feedback network or differential signal path; referenced to VCC– for single-supply biasing. |
| 3 | IN+ | Non-inverting input - connects to sensor output or reference voltage; supports common-mode input range from VCC– +1.15 V to VCC+ –1.15 V. |
| 4 | VCC– | Negative supply terminal - tied to ground in single-supply configurations; must be decoupled with 0.1 μF ceramic capacitor near pin. |
| 5 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 6 | NC | No internal connection - left unconnected; avoids unintended coupling or parasitic capacitance. |
| 7 | NC | No internal connection - left unconnected; maintains signal integrity by preventing stub traces. |
| 8 | VCC+ | Positive supply terminal - accepts 2.7–12 V DC; requires local 0.1 μF + 10 μF decoupling for EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers ±2.4 V swing at ±2.5 V supply - maximizes dynamic range into 12-bit+ automotive ADCs without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel, rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA1671QDRQ1 | Lower noise (2.8 nV/√Hz), higher GBWP (16 MHz), but higher quiescent current (1.6 mA vs. 2.8 mA) | Better suited for ultra-high-fidelity audio; less optimal for low-power always-on sensor nodes | Select when SNR >110 dB is mandatory and supply current budget allows ≥1.6 mA per channel |
| LM7321QDRQ1 | Higher input bias current (150 nA vs. 10–150 nA), lower GBWP (20 MHz), no specified THD+N value | Valid for general-purpose buffering but not recommended for audio or precision sensor signal chains | Choose only for cost-sensitive, non-audio applications where 0.003% THD is not required |
Compared with OPA1671QDRQ1 and LM7321QDRQ1, TL971QDRQ1 uniquely balances ultra-low noise, automotive qualification, and sub-3 mA supply current - making it the optimal choice for battery-conscious infotainment and ADAS signal conditioning where both fidelity and reliability are critical.

FAQ
What is the operating temperature range of the TL971QDRQ1?
The TL971QDRQ1 is qualified per AEC-Q100 Grade 1 and operates reliably from –40°C to +125°C ambient temperature. This range covers under-hood, dashboard, and passenger compartment environments without derating, and is verified through accelerated life testing including temperature cycling and high-temperature operating life (HTOL).
Does TL971QDRQ1 support single-supply operation?
Yes, TL971QDRQ1 supports true single-supply operation from 2.7 V to 12 V. Its input common-mode range extends to VCC– +1.15 V and VCC+ –1.15 V, and its rail-to-rail output delivers ±2.4 V swing at ±2.5 V supply - enabling robust performance in 3.3 V and 5 V automotive domains without dual-rail generation.
What is the maximum capacitive load TL971QDRQ1 can drive stably?
TL971QDRQ1 maintains ≥60° phase margin driving capacitive loads up to 250 pF with 10 kΩ series resistance, as confirmed in TI's SLOS632A datasheet Figure 13. For direct capacitive loads >100 pF, a 10–100 Ω isolation resistor is recommended between output and load to ensure stability in audio and sensor buffer applications.
Is TL971QDRQ1 pin-compatible with other devices in the TL97x-Q1 family?
No - TL971QDRQ1 (single-channel, SOIC-8) is not pin-compatible with TL972QDRQ1 (dual-channel, SOIC-8) or TL974QPWRQ1 (quad-channel, TSSOP-14). Each variant has distinct pinouts: TL971QDRQ1 uses pins 1–4 and 8 for signal/power; TL972QDRQ1 shares VCC+/VCC– but allocates separate IN/OUT pairs; TL974QPWRQ1 requires 14 pins with dedicated supplies per pair.
What packaging and reel specifications apply to TL971QDRQ1?
TL971QDRQ1 is supplied in SOIC-8 (D) package with NIPDAU lead finish, RoHS-compliant, MSL Level-1 (260°C peak reflow), and shipped in large tape-and-reel format: 2500 units per reel, 330 mm reel diameter, 12.4 mm reel width, and Q1 pin-1 quadrant orientation per TI's D0008A outline drawing.
