Product details
Overview
TLV2471IDR from Texas Instruments is a single-channel CMOS rail-to-rail input/output 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 - enabling precision signal conditioning in battery-powered sensor interfaces.
For engineers reviewing the TLV2471IDR datasheet, TLV2471IDR pinout, TLV2471IDR application, or TLV2471IDR equivalent, key selection criteria include rail-to-rail I/O swing, shutdown current <1μA (not applicable to TLV2471IDR), ultra-low input bias current (2.5pA), and SOT23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2471IDR employs a CMOS input stage delivering 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage supports true rail-to-rail swing - reaching within 180mV of each rail at ±10mA load and extending to ±35mA at 500mV from rails - making it suitable for driving low-impedance loads without external level-shifting circuitry.
It operates across an industrial temperature range (–40°C to +125°C) and is fully specified at both 3V and 5V supplies. Unlike the TLV2470/3/5 variants, TLV2471IDR lacks a shutdown pin - confirmed by package pinout (SOT23-5, no SHDN terminal) and family documentation stating "TLV2471 has no shutdown".
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - enables direct operation from single-cell Li-ion (3.0–3.7V) or dual-AA (3.0V) supplies without regulation. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop gain ≥10 up to ~280kHz, sufficient for anti-aliasing, sensor amplification, and active filtering. |
| Input Bias Current | 2.5pA (typ) - minimizes voltage error in high-impedance source networks (e.g., pH electrodes, photodiode transimpedance inputs). |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly (e.g., ADC reference buffers, LED drivers, analog multiplexer outputs). |
| Input Offset Voltage | 250μV (typ) - contributes ≤0.008% error in unity-gain 3V full-scale systems, suitable for 12-bit precision applications. |
| Supply Current per Channel | 600μA (typ at 5V) - enables >10-year battery life in always-on 3V coin-cell applications drawing <1μA average system current. |
| CMRR / PSRR | ≥58dB (min) - rejects power supply ripple and common-mode noise in noisy industrial environments with unregulated rails. |
Pinout & Package
SOT23-5 package (DBV), 2.9mm × 1.6mm footprint, surface-mount, tape-and-reel compatible. RoHS-compliant, moisture sensitivity level 1.
| 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 (10¹²Ω); accepts signals from 0V to VDD with minimal loading on feedback networks. |
| 3 - IN+ | Non-inverting input | Matches IN− characteristics; used for unity-gain buffers, instrumentation front-ends, and precision references. |
| 4 - GND | Analog ground reference | Must be connected to low-impedance system ground plane; separates analog return from digital or power ground paths. |
| 5 - VDD | Positive supply | Accepts 2.7V–6V; internal ESD protection rated to ±2kV HBM; requires local 0.1μF ceramic decoupling capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in low-voltage (3V) systems - e.g., 0–3V output swing preserves 12-bit resolution in 3V ADC interfaces. |
| Ultra-low input bias current (2.5pA) | Reduces offset drift in high-Z sensor circuits (e.g., piezoelectric accelerometers, capacitive humidity sensors) without requiring guard traces or T-network compensation. |
| High output drive (±35mA) | Eliminates need for external buffer stages when driving SAR ADC input capacitors, analog switches, or low-impedance transducers. |
| Low quiescent current (600μA) | Supports always-on signal monitoring in portable medical devices (e.g., pulse oximeter front-end) with sub-10μA system sleep current. |
| Industrial temperature range (–40°C to +125°C) | Validated for under-hood automotive sensor signal conditioning and industrial motor control feedback loops without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1μV/°C offset drift vs. TLV2471IDR's 0.4μV/°C; higher 350kHz GBW; 17μA supply current. | Better DC precision for <16-bit systems; unsuitable for high-speed or high-output-drive needs. | Select OPA333AIDBVR when offset drift dominates error budget; avoid when >10mA load or >1MHz bandwidth required. |
| MCP6001T-E/OT | Lower cost CMOS op-amp; 100μA supply current; 1MHz GBW; ±6mA output drive; same SOT23-5 package. | Optimized for ultra-low-power always-on monitoring, not high-fidelity signal chains. | Select MCP6001T-E/OT for battery-life-critical applications where 2.8MHz bandwidth and ±35mA drive are unnecessary. |
Compared with OPA333AIDBVR and MCP6001T-E/OT, TLV2471IDR uniquely balances 2.8MHz bandwidth, ±35mA output, and 600μA quiescent current in SOT23-5 - filling a gap between micropower and high-drive op-amps for industrial sensor nodes requiring both speed and robustness.

FAQ
Does TLV2471IDR include a shutdown feature?
No, TLV2471IDR does not have a shutdown function. The TLV2471 variant is explicitly defined in the datasheet as lacking a shutdown pin - unlike TLV2470/3/5. Its SOT23-5 pinout contains only OUT, IN−, IN+, GND, and VDD terminals. Shutdown current specifications (e.g., 350nA at 3V) apply only to those variants with a dedicated SHDN pin.
What is the maximum capacitive load TLV2471IDR can drive stably?
TLV2471IDR remains stable with capacitive loads ≤10pF when directly connected. For larger loads (e.g., ADC input capacitance), Texas Instruments recommends adding a series null resistor (RNULL ≥20Ω) between the amplifier output and the load - as documented in Figure 42 of the TLV247x datasheet - to maintain phase margin above 45° and prevent oscillation.
Is TLV2471IDR suitable for single-supply 3.3V operation?
Yes, TLV2471IDR is fully specified for 3.3V single-supply operation. Its 2.7V–6V supply range, rail-to-rail input (0V to VDD), and rail-to-rail output (within 180mV of rails at 10mA) ensure full functionality at 3.3V. Electrical characteristics tables confirm parameters like 600μA supply current and 2.8MHz GBW are validated at 3V and 5V.
How does TLV2471IDR's input offset voltage compare across temperature?
TLV2471IDR has a typical input offset voltage drift of 0.4μV/°C. At 25°C, VIO is 250μV (typ); over the full –40°C to +125°C range, max VIO is 2400μV for I-suffix devices. This drift performance is consistent across supply voltages and makes TLV2471IDR suitable for applications where ambient temperature varies but absolute DC accuracy below 2.4mV is acceptable.
Can TLV2471IDR replace older TLC2271 in existing designs?
TLV2471IDR can replace TLC2271 in most cases due to pin compatibility in SOIC-8 and improved specs: lower supply current (600μA vs. 1.3mA), higher GBW (2.8MHz vs. 2.2MHz), and better output drive (±35mA vs. ±10mA). However, verify layout compatibility - TLV2471IDR in SOT23-5 requires footprint redesign versus SOIC-8 TLC2271, and its input bias current (2.5pA) differs significantly from TLC2271's 1pA.
