Product details
Overview
TLV2471CP 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 - enabling precision signal conditioning in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2471CP datasheet, TLV2471CP pinout, TLV2471CP application, or TLV2471CP equivalent, this page provides verified technical context, package-specific pin definitions, real-world use cases, and validated alternative options - all grounded in TI's SLOS232E datasheet and official ordering documentation.
Technical Context
The TLV2471CP operates as a unity-gain-stable, internally compensated 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, or within 500mV at ±35mA). Its CMOS input stage achieves 2.5pA typical input bias current and 10¹²Ω differential input resistance, supporting high-impedance source interfacing without significant error.
It features no shutdown functionality (unlike TLV2470/2473/2475), confirmed by absence of SHDN pin in DBV-5 and PDIP-8 package variants and omission from TLV2471's pinout diagrams and electrical specs. Performance is fully specified across 0°C to +70°C (C-suffix) and –40°C to +125°C (I-suffix) temperature ranges at both 3V and 5V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports single-cell Li-ion, dual-AA, and USB-powered systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - enables stable closed-loop operation up to ~200kHz with moderate gain (e.g., AV = 10). |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV output error in unity-gain buffer configurations at room temperature. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly (e.g., ADC reference buffers, analog multiplexers). |
| Supply Current per Channel | 600μA (typ at 5V) - balances speed and power for always-on signal chains in portable instrumentation. |
| Input Bias Current | 2.5pA (typ) - minimizes voltage drop across >100MΩ sensor elements (e.g., pH electrodes, photodiodes). |
| Common-Mode Rejection Ratio | 84dB (typ at 5V) - rejects noise coupled equally to both inputs in noisy industrial environments. |
Pinout & Package
TLV2471CP is supplied in an 8-pin Plastic DIP (PDIP) package with 0.300-inch body width and through-hole mounting. Pin 1 is 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 in inverting configurations or reference point in transimpedance amps. |
| 3 | IN+ | Non-inverting input terminal - accepts high-impedance sensor signals or reference voltages with minimal loading. |
| 4 | GND | Analog ground reference - requires low-impedance connection to system AGND plane for noise immunity. |
| 5 | VDD | Positive supply rail - decoupling capacitor (0.1μF ceramic) must be placed within 5mm of this pin. |
| 6 | OUT | Amplifier output - capable of sourcing/sinking ±35mA while maintaining rail-to-rail swing under load. |
| 7 | NC (No internal connection) | Unused pad; electrically isolated and thermally disconnected from die. |
| 8 | NC (No internal connection) | Unused pad; no internal bond wire or circuit connection; leave floating or tie to GND only if required for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3V systems - e.g., digitizing 0–3V sensor outputs without level-shifting. |
| 600μA/channel ultra-low quiescent current | Extends battery life in continuous-monitoring devices - e.g., wearable ECG front-ends operating on coin cells for >1 year. |
| ±35mA high output drive | Eliminates need for external buffer stages when driving SAR ADC inputs, relay drivers, or LED bias circuits. |
| 2.5pA input bias current | Preserves accuracy in microamp-level current measurement paths - critical for gas sensor and leakage current detection. |
| 2.8MHz bandwidth with unity-gain stability | Supports fast-settling acquisition in data loggers sampling at ≥100kSPS with <1μs settling time to 0.01%. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CP | Higher 6.4MHz GBW and ±90mA output drive, but 550μA supply current and 150μV offset - trades power for speed and drive. | Preferred in active filter designs requiring >1MHz closed-loop bandwidth or driving capacitive loads >1nF. | Select TLV2461CP when higher slew rate (1.6V/μs) and bandwidth are needed; verify thermal dissipation in PDIP-8 at full output swing. |
| MCP6001-I/P | Lower 1MHz GBW and ±23mA drive, but 100μA supply current and 20μV offset - optimized for micropower, not high drive. | Suitable for always-on sensor wake-up circuits where <100μA total system current is mandatory. | Choose MCP6001-I/P only when supply current is the dominant constraint and output drive requirements are ≤±23mA. |
Compared with TLV2471CP, TLV2461CP offers greater bandwidth and output strength at modestly higher current, while MCP6001-I/P sacrifices speed and drive to achieve 6× lower quiescent current - making TLV2471CP the balanced choice for mid-speed, high-drive, rail-to-rail applications.

FAQ
Does TLV2471CP include a shutdown feature?
No, TLV2471CP does not include a shutdown function. Unlike TLV2470/2473/2475, the TLV2471 variant lacks a SHDN pin and corresponding internal circuitry - confirmed by its 5-pin SOT23 and 8-pin PDIP pinouts showing no shutdown terminal and absence of IDD(SHDN) specifications in its datasheet tables.
What is the maximum capacitive load TLV2471CP can drive without instability?
TLV2471CP remains stable with ≤10pF capacitive load directly at the output. For larger loads (e.g., ADC input capacitance), TI recommends adding a series null resistor (RNULL ≥20Ω) between the amplifier output and the load - as documented in Figure 42 of the SLOS232E datasheet - to maintain ≥61° phase margin.
Can TLV2471CP operate from a 2.5V supply?
No, TLV2471CP has a minimum rated supply voltage of 2.7V per the Absolute Maximum Ratings and Recommended Operating Conditions tables. Operation below 2.7V is not characterized and may result in degraded parameters including reduced output swing, increased offset, or failure to meet AC specifications.
Is TLV2471CP pin-compatible with other TLV247x variants in PDIP-8?
No, TLV2471CP is not pin-compatible with TLV2470CP or TLV2472CP in PDIP-8. TLV2470CP uses pins 1 (SHDN), 5 (VDD), and 8 (OUT); TLV2471CP uses pins 2 (IN−), 3 (IN+), 4 (GND), 5 (VDD), and 6 (OUT), with pins 1/7/8 designated NC - requiring PCB layout changes for substitution.
What is the thermal resistance (θJA) of TLV2471CP in PDIP-8 package?
The junction-to-ambient thermal resistance (θJA) for TLV2471CP in PDIP-8 (P package) is 104°C/W, as specified in the Dissipation Rating Table of the SLOS232E datasheet - enabling calculation of maximum allowable power dissipation (1200mW at TA ≤+25°C) and safe operating area under load conditions.
