Product details
Overview
TLV2471IP from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive applications. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage across 2.7V–6V supply range - ideal for precision sensor signal conditioning in battery-powered medical or portable instrumentation.
For engineers reviewing the TLV2471IP datasheet, TLV2471IP pinout, TLV2471IP application, or TLV2471IP equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative op-amps with documented functional trade-offs for low-voltage, rail-to-rail signal acquisition designs.
Technical Context
The TLV2471IP uses a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), supporting true single-supply operation down to 2.7V. Its output stage delivers ±35mA into loads while swinging within 500mV of either rail - a key advantage over legacy micropower op-amps.
It features no internal shutdown control (unlike TLV2470/2473/2475), eliminating shutdown-related timing delays and leakage paths. Performance is fully specified across –40°C to +125°C, with stable phase margin (>61°) into 1nF capacitive loads when using recommended RNULL compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - enables direct interface with Li-ion, 3.3V, and 5V systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop gain up to ~28 at 100kHz for anti-aliasing or sensor amplification. |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit ADC front-ends without trimming. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly (e.g., analog multiplexer inputs or DAC buffers). |
| Supply Current per Channel | 600μA (typ at 5V) - allows >1000 hours runtime on a 600mAh coin cell in duty-cycled sensor nodes. |
| Input Bias Current | 2.5pA (typ) - preserves high-impedance source integrity (e.g., pH electrodes, piezoelectric sensors). |
| Common-Mode Input Range | 0V to VDD - accepts ground-referenced signals in single-supply configurations without AC coupling. |
Pinout & Package
TLV2471IP is housed in an 8-pin plastic DIP (PDIP) package with 0.300-inch body width and through-hole mounting. Pin 1 is located at the left end of the top row, identified by a beveled edge or molded dot.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC (No Internal Connection) | Unused pad; must remain unconnected to avoid parasitic coupling or mechanical stress. |
| 2 | IN− | Inverting input terminal - connects to feedback network or differential reference in transimpedance configurations. |
| 3 | IN+ | Non-inverting input terminal - accepts high-impedance sensor outputs or reference voltages directly. |
| 4 | GND | Analog ground reference - requires low-impedance connection to system AGND plane for noise immunity. |
| 5 | VDD | Positive supply rail - decoupled with 0.1μF ceramic capacitor placed <1cm from pin for stability. |
| 6 | OUT | Amplified output - capable of sourcing/sinking ±35mA while maintaining rail-to-rail swing under load. |
| 7 | NC (No Internal Connection) | Unused pad; electrically isolated - no routing or thermal relief required. |
| 8 | NC (No Internal Connection) | Unused pad; serves only as mechanical anchor - leave floating per TI layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3V systems - e.g., 0–3.3V ADC input span without clipping. |
| Ultra-low input bias current (2.5pA) | Minimizes voltage error across high-value feedback resistors (>10MΩ) used in photodiode amplifiers. |
| High output drive (±35mA) | Eliminates need for external buffer stages when driving low-impedance loads like relay coils or LED strings. |
| Low quiescent current (600μA) | Supports always-on monitoring circuits in energy-harvesting or battery-backed IoT endpoints. |
| Specified over –40°C to +125°C | Validates performance in automotive cabin modules, industrial motor controllers, and outdoor sensor enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 0.1μV/°C offset drift vs. TLV2471IP's 0.4μV/°C; 17μA supply current vs. 600μA. | Superior DC accuracy for long-term sensor calibration; unsuitable for high-output-drive or low-quiescent-current use cases. | Select OPA333AIDR only when sub-μV offset stability dominates power or drive requirements. |
| MCP6001T-E/OT | Lower drive (±23mA); higher input bias (1pA vs. 2.5pA); same 2.7–6V supply; 100kHz GBW vs. 2.8MHz. | Better suited for low-frequency, ultra-low-cost sensor buffers where bandwidth <100kHz suffices. | Choose MCP6001T-E/OT for cost-sensitive, low-bandwidth applications where ±35mA drive is unnecessary. |
Compared with TLV2471IP, OPA333AIDR trades 23× higher quiescent current for 10× lower offset drift, while MCP6001T-E/OT reduces cost and size but sacrifices 28× bandwidth and 52% output drive - making TLV2471IP optimal for balanced low-power, high-fidelity, high-drive signal chains.

FAQ
What is the operating temperature range for TLV2471IP?
The TLV2471IP is rated for operation from –40°C to +125°C, meeting industrial and extended-temperature requirements. This range is validated across all key parameters including input offset voltage, supply current, and output drive capability - ensuring reliability in automotive engine compartments, factory-floor controllers, and outdoor sensor housings without derating.
Does TLV2471IP include a shutdown pin?
No, TLV2471IP does not feature a shutdown pin. Unlike TLV2470, TLV2473, or TLV2475, the TLV2471IP variant omits shutdown functionality entirely. Its pinout contains three NC pins and no SHDN terminal - simplifying PCB layout and eliminating shutdown timing uncertainty, but requiring system-level power gating if ultra-low standby current is needed.
What is the maximum capacitive load TLV2471IP can drive stably?
TLV2471IP remains stable with up to 100pF capacitive load when configured as a unity-gain follower, per TI's characterization data. For loads exceeding 10pF, TI recommends adding a series null resistor (RNULL ≥20Ω) between the output and capacitive node - a proven method to restore phase margin above 61° and prevent ringing in ADC driver or filter applications.
Can TLV2471IP operate from a 2.7V single supply?
Yes, TLV2471IP is fully specified at 2.7V single supply, with guaranteed rail-to-rail input common-mode range (0V to VDD) and output swing within 500mV of each rail. At 2.7V, it maintains 2.8MHz gain-bandwidth and 600μA supply current - enabling direct interfacing with low-voltage microcontrollers and energy-harvesting PMUs without voltage boosting.
How does TLV2471IP's input bias current affect high-impedance sensor interfaces?
With a typical input bias current of 2.5pA, TLV2471IP introduces ≤2.5μV error across a 1MΩ source impedance - negligible in most precision sensor applications. This enables direct connection to pH electrodes, photodiodes, and thermopiles without guard traces or T-network compensation, preserving signal integrity while minimizing board area and BOM count.
