Product details
Overview
TLV2471CDBVRG4 from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for ultra-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 TLV2471CDBVRG4 datasheet, TLV2471CDBVRG4 pinout, TLV2471CDBVRG4 application, or TLV2471CDBVRG4 equivalent, key selection criteria include its rail-to-rail I/O swing, shutdown current of 350nA at 3V (not present on this variant), absence of shutdown pin, SOT23-5 package constraints, and verified performance at 3V/5V with ±10mA/±35mA drive capability under real load conditions.
Technical Context
The TLV2471CDBVRG4 implements a CMOS input stage with rail-to-rail common-mode input range (0V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA, within 500mV at ±35mA). Its 2.8MHz unity-gain bandwidth and 1.5V/μs slew rate support stable closed-loop operation with capacitive loads up to 1000pF when properly compensated using series RNULL.
It operates across 2.7V–6V single-supply or ±1.35V–±3V split-supply configurations, with input bias current of 2.5pA (typ), CMRR of 88dB (typ at 25°C), and PSRR of 78dB (typ at 25°C). The device is fully specified over 0°C to +70°C (C-suffix) and exhibits low 15nV/√Hz input voltage noise at 1kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct integration into 3.3V and 5V systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~280kHz. |
| Output Drive Capability | ±35mA at 500mV from rail - drives heavy loads like ADC reference buffers or LED drivers without external transistors. |
| Input Offset Voltage | 250μV (typ) - ensures <0.01% error in 2.5V full-scale precision instrumentation front-ends. |
| Supply Current per Channel | 600μA (typ at 25°C) - enables multi-channel sensing nodes with sub-1mA total quiescent current. |
| Input Bias Current | 2.5pA (typ) - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiodes). |
| Common-Mode Input Range | 0V to VDD - accepts signals directly from resistive sensors or DAC outputs referenced to ground or VDD. |
Pinout & Package
SOT23-5 package: 5-pin ultra-small outline transistor (SOT-23) with gull-wing leads, 1.6mm × 2.9mm footprint, 0.95mm height, and thermal pad not present (non-PowerPAD variant).
| 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; 2.5pA bias current enables use with MΩ-range feedback networks. |
| 3 (IN+) | Non-inverting input | Accepts common-mode signals from 0V to VDD; supports direct connection to grounded sensors or DAC outputs. |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load current; must be low-impedance for noise control. |
| 5 (VDD) | Positive supply | Accepts 2.7V–6V; internal regulation ensures stable operation across battery discharge profiles. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in low-voltage (3V) systems - e.g., preserves 3.0Vpp signal swing in 3.3V supply rails. |
| 600μA/channel quiescent current | Supports always-on sensor monitoring with <1.5μA per channel in 4-channel designs - critical for coin-cell lifetime. |
| ±35mA output drive | Eliminates need for external buffer stages when driving 10kΩ ADC references or 100Ω transmission lines. |
| 2.8MHz bandwidth with 1.5V/μs slew rate | Stably amplifies 200kHz sine waves with <1% distortion at 2Vpp output into 10kΩ load. |
| 250μV max input offset (C-grade) | Reduces calibration overhead in factory-trimmed systems - e.g., maintains ≤0.01% FS error in 25°C temperature-sensing bridges. |
| Specified from 0°C to +70°C | Validated for commercial industrial environments including HVAC controllers and metering terminals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA344UA/2K5 | Lower 500μA supply current but only 1MHz GBW and ±16mA output drive; no rail-to-rail input. | Better for ultra-low-power, low-bandwidth sensor buffering where input common-mode range >1V from rail is acceptable. | Select OPA344UA/2K5 only if bandwidth <1MHz suffices and input signal stays >1V from either rail. |
| MCP6001T-E/OT | Same SOT23-5 package, 1μA supply current, 1MHz GBW, rail-to-rail I/O, but only ±6mA output drive and 3mV max VIO. | Cost-optimized for non-precision applications like GPIO voltage translation or simple comparators with hysteresis. | Choose MCP6001T-E/OT for cost-sensitive, low-speed general-purpose use - not for precision or high-drive requirements. |
Compared with OPA344UA/2K5 and MCP6001T-E/OT, TLV2471CDBVRG4 uniquely balances 2.8MHz bandwidth, ±35mA drive, and rail-to-rail I/O in a 5-pin SOT23 - making it the only option among the three suitable for driving 10kΩ loads at 200kHz while maintaining DC accuracy below 0.01% FS.

FAQ
What is the maximum capacitive load the TLV2471CDBVRG4 can drive without oscillation?
The TLV2471CDBVRG4 remains stable with capacitive loads up to 1000pF when configured as a unity-gain buffer with proper PCB layout (short traces, ground plane). For loads >10pF, TI recommends adding a 20Ω–100Ω series resistor (RNULL) between the output pin and the load capacitance to preserve phase margin above 61° - confirmed in Figure 18 of the TLV2471CDBVRG4 datasheet.
Does the TLV2471CDBVRG4 have a shutdown pin?
No, the TLV2471CDBVRG4 does not include a shutdown function. The TLV2470 variant (SOT23-6) provides shutdown capability, but TLV2471CDBVRG4 is the single-channel, 5-pin version without SHDN pin - verified by its SOT23-5 pinout diagram and absence of shutdown current specs in its electrical characteristics table.
What is the input common-mode voltage range for TLV2471CDBVRG4 at 3.3V supply?
At VDD = 3.3V, the TLV2471CDBVRG4 supports a common-mode input voltage range from 0V to 3.3V - full rail-to-rail - enabling direct interfacing with 0–3.3V DAC outputs, resistive divider sensors, or other 3.3V-referenced sources without level-shifting circuitry.
Can TLV2471CDBVRG4 operate from a single 2.7V supply?
Yes, TLV2471CDBVRG4 is fully specified down to 2.7V supply voltage. At 2.7V, it maintains 2.8MHz gain-bandwidth, 600μA supply current, and rail-to-rail I/O functionality - making it suitable for applications powered by partially discharged lithium coin cells or low-dropout regulators in space-constrained designs.
How does the input offset voltage of TLV2471CDBVRG4 vary with temperature?
The TLV2471CDBVRG4 has a temperature coefficient of input offset voltage (αVIO) of 0.4μV/°C (max), meaning its offset drifts less than 20μV over a 0°C to +70°C ambient range - contributing <0.001% FS error in a 2V full-scale system, which is negligible for most industrial sensor applications without trimming.
