Product details
Overview
TLV2471ID 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 a 2.7V–6V supply range - ideal for precision sensor signal conditioning in battery-powered medical and industrial data acquisition systems.
For engineers reviewing the TLV2471ID datasheet, TLV2471ID pinout, TLV2471ID application, or TLV2471ID equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in TI's SLOS232E datasheet and official ordering documentation.
Technical Context
The TLV2471ID operates as a unity-gain-stable, internally compensated voltage-feedback op amp with rail-to-rail input common-mode range (0V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA). Its CMOS input stage achieves 2.5pA typical input bias current and 10¹²Ω differential input resistance, enabling high-impedance source interfacing without significant error.
It features no shutdown pin - unlike TLV2470/2473/2475 - and is specified over –40°C to +125°C. Performance is fully characterized at both 3V and 5V supplies, with 1.5V/μs slew rate, 61° phase margin into 1nF, and <0.1% THD+N at 1kHz with 4Vpp output into 10kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports single-cell Li-ion, dual-AA, and 3.3V/5V system rails without level shifting. |
| Gain-Bandwidth Product | 2.8MHz - enables stable closed-loop operation up to ~200kHz with gain ≥10, suitable for anti-aliasing and active filtering. |
| Input Offset Voltage (typ) | 250μV - contributes ≤0.5mV error in 2V full-scale 12-bit ADC front-end; drift ≤0.4μV/°C minimizes thermal error. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly, eliminating external buffers in DAC output stages or LED drivers. |
| Supply Current per Channel | 600μA - enables >1-year battery life in continuous-sensing nodes powered by CR2032 (220mAh). |
| Input Bias Current (typ) | 2.5pA - allows use with >100MΩ sensor elements (e.g., pH electrodes, piezoresistive bridges) without significant bias-induced offset. |
| CMRR / PSRR (min) | 58dB / 66dB - rejects power rail noise and common-mode interference in noisy industrial environments. |
Pinout & Package
SOT-23-5 package (DBV), 5-pin surface-mount, 2.9mm × 1.6mm footprint, 0.95mm height - compatible with high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±35mA while staying within 500mV of supply rails. |
| 2 (IN−) | Inverting Input | High-impedance CMOS node; connects to feedback network in inverting configurations or reference in transimpedance designs. |
| 3 (IN+) | Non-Inverting Input | High-impedance CMOS node; accepts signals from high-Z sensors or filtered references without loading. |
| 4 (GND) | Analog Ground Reference | Primary return path for input bias currents and output load current; must be tied to clean analog ground plane. |
| 5 (VDD) | Positive Supply Rail | Accepts 2.7V–6V; decoupling capacitor (0.1μF ceramic) required within 2mm for stability and noise immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1μV/°C offset drift vs. TLV2471ID's 0.4μV/°C; 350kHz GBW vs. 2.8MHz; 17μA supply current. | Better DC precision for <1Hz sensor apps; lower bandwidth limits AC-coupled signal paths. | Select OPA333AIDBVR when sub-μV offset stability dominates over speed and drive capability. |
| MCP6001T-I/OT | 1MHz GBW; 100μA supply current; 2mV max VIO; 7mA output drive; same SOT-23-5 package. | Lower cost and power, but insufficient drive for 100Ω loads and higher offset degrades 12-bit+ resolution. | Select MCP6001T-I/OT only for non-critical, low-drive, cost-sensitive consumer applications where 2.8MHz and ±35mA are unnecessary. |
Compared with OPA333AIDBVR and MCP6001T-I/OT, TLV2471ID uniquely balances 2.8MHz bandwidth, ±35mA output drive, and 600μA quiescent current - making it the optimal choice for battery-powered, high-fidelity sensor interfaces requiring both speed and robust load handling.

FAQ
What is the maximum capacitive load the TLV2471ID can drive without instability?
The TLV2471ID remains stable with up to 100pF capacitive load when properly decoupled. For loads >10pF, TI recommends adding a 20Ω series resistor (RNULL) between the output and load to maintain ≥61° phase margin. This is confirmed in Figure 42 of the SLOS232E datasheet and validated across –40°C to +125°C for TLV2471ID.
Does TLV2471ID include a shutdown pin?
No, TLV2471ID does not have a shutdown pin. Only TLV2470, TLV2473, and TLV2475 in the same family feature shutdown functionality. TLV2471ID is a single-channel, non-shutdown variant in SOT-23-5 (DBV) package - confirmed by the Family Package Table and pinout diagrams in the TLV247x datasheet.
What is the input common-mode voltage range for TLV2471ID?
The TLV2471ID supports rail-to-rail input common-mode voltage range: 0V to VDD. This is explicitly stated in the Recommended Operating Conditions table (VICR = 0 to VDD) and verified across 2.7V–6V supplies and –40°C to +125°C, enabling direct sensing of signals near ground or supply rails.
Can TLV2471ID operate from a 2.7V supply while delivering full output swing?
Yes, TLV2471ID guarantees rail-to-rail output swing down to 2.7V supply. At 2.7V and 25°C, it delivers ±10mA output within 180mV of each rail and ±35mA within 500mV - confirmed in the "High Output Drive Capability" section and Electrical Characteristics tables for VDD = 2.7V–6V.
Is TLV2471ID pin-compatible with other SOT-23-5 op amps like MCP6001 or LMV321?
TLV2471ID uses standard SOT-23-5 pinout (OUT/IN−/IN+/GND/VDD), matching industry convention. However, functional compatibility requires verification: MCP6001 shares the same pinout but has lower drive (7mA) and bandwidth (1MHz); LMV321 is pin-compatible but not rail-to-rail input. Always validate schematic integration using TLV2471ID's specific electrical behavior.
