Product details
Overview
TLV271CD from Texas Instruments is a single-channel, rail-to-rail output operational amplifier optimized for low-power, wide-bandwidth signal conditioning in battery-powered and industrial systems. It delivers 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, 550 µA supply current per channel, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V - enabling use in Li-ion powered instrumentation and sensor interfaces.
For engineers reviewing the TLV271CD datasheet, TLV271CD pinout, TLV271CD application, or TLV271CD equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for design-in and BOM continuity planning.
Technical Context
The TLV271CD employs CMOS input stage architecture delivering 1 pA typical input bias current and rail-to-rail output swing down to within 135 mV of each rail at 1 mA load. Its 3-MHz gain-bandwidth product and 65° phase margin (with 10 pF capacitive load) support stable unity-gain buffer and active filter configurations across its full 2.7–16 V supply range.
It is fully specified over the commercial temperature range (0°C to 70°C), with DC parameters including 5 mV typical input offset voltage, 70 dB minimum CMRR at 2.7 V, and 80 dB PSRR - making it suitable for precision analog front-ends where supply rejection and common-mode immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell Li-ion (3.0–4.2 V), dual alkaline (3 V), and ±5 V split supplies without level-shifting. |
| Bandwidth (UGBW) | 3 MHz - enables accurate amplification of signals up to ~200 kHz in closed-loop gain ≥ 15 configurations. |
| Slew Rate | 2.4 V/µs - supports 1-Vpp output at 380 kHz without distortion in unity-gain follower mode. |
| Input Bias Current | 1 pA - permits high-impedance sensor interfacing (e.g., pH electrodes, photodiodes) without significant DC error. |
| Input Voltage Noise | 39 nV/√Hz - ensures low-noise signal conditioning for 20-bit ADC drivers and precision transducer amplifiers. |
| Rail-to-Rail Output | Swings to within 135 mV of VDD and GND at 1 mA - maximizes dynamic range in low-voltage microcontroller-based systems. |
| Quiescent Current | 550 µA per channel - enables multi-day operation in always-on smoke detectors and building automation sensors. |
Pinout & Package
TLV271CD is packaged in an 8-pin SOIC (D package) with 4.98 mm × 3.91 mm body size and standard JEDEC MS-012AC footprint.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - drives loads up to ±100 mA short-circuit current; requires series resistor for >10 pF capacitive loads. |
| 2 | IN− | Inverting input - high-impedance CMOS node; sensitive to PCB leakage and EMI; requires symmetric trace routing in precision designs. |
| 3 | IN+ | Noninverting input - matched to IN− for optimal CMRR; connects to reference voltage or sensor in instrumentation topologies. |
| 4 | GND | Negative supply reference - must be low-impedance connection to system ground plane; separate analog/digital grounding recommended. |
| 5 | NC | No internal connection - electrically isolated; may be left floating or tied to GND for mechanical stability (not required). |
| 6 | NC | No internal connection - same as Pin 5; no electrical function. |
| 7 | VDD | Positive supply input - accepts 2.7–16 V; bypass capacitor (0.1 µF ceramic) required within 5 mm of pin for stability. |
| 8 | NC | No internal connection - same as Pins 5 and 6; no routing or termination needed. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale signal headroom in 3.3 V and 5 V microcontroller systems, eliminating need for level-shifting circuitry. |
| 1 pA input bias current | Enables direct interface with high-impedance sources (≥100 MΩ) without measurable offset drift due to source resistance. |
| 3-MHz bandwidth at 550 µA | Provides 5× higher speed-per-power than legacy TLC271, enabling faster response in motor control feedback loops and power bank monitors. |
| Specified from 2.7 V to 16 V | Supports seamless migration from 5 V to Li-ion battery rails (3.0–4.2 V) without redesigning supply regulation or bias networks. |
| 39 nV/√Hz input voltage noise | Meets SNR requirements for 16-bit ADC drivers in portable test equipment and battery-powered data loggers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV271IDR | Industrial-grade variant rated for −40°C to +125°C; otherwise identical electrical specs and pinout. | Required for automotive cabin modules, solar inverter monitoring, and outdoor building controls exposed to extended temperature extremes. | Select TLV271IDR when ambient operating temperature exceeds 70°C or safety-critical reliability validation is mandated. |
| TLV2371CDR | Includes shutdown control (active-low EN pin); 550 µA quiescent current in active mode; 100 nA in shutdown. | Used in duty-cycled sensor nodes where periodic wake-up and deep-sleep power gating are implemented. | Choose TLV2371CDR only if system-level power management requires hardware-controlled disable functionality - TLV271CD has no shutdown capability. |
Compared with TLV271IDR, the TLV271CD offers lower cost and sufficient performance for indoor consumer electronics, while TLV2371CDR adds complexity and cost solely for shutdown capability - unnecessary unless microcontroller-driven power cycling is architecturally required.

FAQ
What is the maximum supply voltage for TLV271CD?
The absolute maximum supply voltage for TLV271CD is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, the device maintains full rail-to-rail output swing and 3-MHz bandwidth, making it compatible with 12-V industrial rails and ±8-V split supplies.
Does TLV271CD support rail-to-rail input?
No, TLV271CD does not feature rail-to-rail input. Its common-mode input voltage range is specified as 0 V to VDD − 1.35 V. This means the input cannot accept signals within 1.35 V of the positive rail. For true rail-to-rail input capability, consider TI's TLV2461 or OPA333 families - TLV271CD is optimized for rail-to-rail output only.
Can TLV271CD drive capacitive loads directly?
TLV271CD can drive ≤10 pF capacitive loads stably. For loads >10 pF (e.g., long PCB traces, ADC input capacitance), TI recommends adding a 20–100 Ω series resistor between the TLV271CD output and the load to preserve phase margin and prevent oscillation - confirmed in Figure 26 of the SLOS351E datasheet.
What is the input offset voltage specification for TLV271CD?
The TLV271CD has a maximum input offset voltage of 7 mV over the full 0°C to 70°C commercial temperature range, with a typical value of 5 mV at 25°C. This is measured with VDD = 2.7 V, 5 V, or ±5 V, RL = 10 kΩ, and VO = VDD/2. The offset drift is 2 µV/°C, supporting stable DC-coupled gain stages in temperature-varying environments.
Is TLV271CD pin-compatible with TLC271?
Yes, TLV271CD is pin-compatible with TLC271 in the same SOIC-8 package (D), sharing identical pinout and footprint. However, TLV271CD improves upon TLC271 with rail-to-rail output, lower supply current (550 µA vs. 675 µA), wider bandwidth (3 MHz vs. 1.7 MHz), and enhanced CMRR - making it a direct functional upgrade without PCB changes.
