Product details
Overview
TLV2471CDR 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 supply current per channel, ±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 devices.
For engineers reviewing the TLV2471CDR datasheet, TLV2471CDR pinout, TLV2471CDR application, or TLV2471CDR equivalent, key selection criteria include its rail-to-rail I/O swing, shutdown absence (distinguishing it from TLV2470/2473), SOT23-5 package footprint, and verified performance at 3V/5V with <0.5μV/°C drift - critical for low-voltage analog front-ends requiring minimal quiescent power and wide dynamic range.
Technical Context
The TLV2471CDR employs a CMOS input stage enabling 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 under load: ±10mA within 180mV of each rail, and ±35mA at 500mV off-rail - resolving classic micropower op-amp drive limitations.
It operates across 2.7V–6V supply, with 600μA/channel quiescent current and 2.8MHz unity-gain bandwidth. Unlike TLV2470/2473, it lacks a shutdown pin - simplifying control logic but eliminating sub-μA sleep mode. Temperature range is 0°C to +70°C (C-suffix), validated per TI's SLOS232E specification.
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 moderate gain (e.g., G=10) in sensor amplification stages. |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit ADC interfaces without trimming. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly, eliminating external buffers in transducer drivers. |
| Supply Current per Channel | 600μA - enables >1-year battery life in continuous 3V monitoring systems with 10μA average system budget. |
| Input Bias Current | 2.5pA - preserves signal integrity in high-impedance pH or photodiode sensor nodes (>1GΩ source impedance). |
| CMRR / PSRR | ≥88dB / ≥74dB - rejects noise from shared 3.3V digital supplies in mixed-signal PCB layouts. |
Pinout & Package
SOT23-5 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, moisture sensitivity level 1, RoHS-compliant.
| 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 <2.5pA bias current. |
| 3 - IN+ | Non-inverting input | Matches IN− characteristics; enables precision differential sensing with matched trace routing. |
| 4 - GND | Analog ground reference | Must be tied to low-impedance system ground plane; separates analog return from digital AGND/DGND. |
| 5 - VDD | Positive supply | Accepts 2.7V–6V; decoupling capacitor (0.1μF ceramic) required within 5mm for stability. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA344UA | Lower 500μA supply current, 1MHz GBW, no rail-to-rail output - saturates >100mV from rails. | Less suitable for 3V full-scale signal chains requiring >2.8Vpp output swing. | Select when lower power dominates over output swing and bandwidth requirements. |
| MCP6001T-E/OT | Higher 100μA supply current, 1MHz GBW, rail-to-rail I/O, but only ±6mA output drive. | Insufficient for driving 100Ω loads or 4–20mA loops without external transistor. | Prefer for cost-sensitive, low-speed (<100kHz), low-current sensor interfaces where board space is constrained. |
Compared with OPA344UA and MCP6001T-E/OT, TLV2471CDR uniquely balances 2.8MHz bandwidth, rail-to-rail I/O, ±35mA drive, and 600μA consumption - making it the only option among the three capable of driving moderate loads at higher frequencies without external components.

FAQ
What is the operating temperature range for TLV2471CDR?
The TLV2471CDR is specified for 0°C to +70°C ambient operation (C-suffix grade), validated per TI's SLOS232E datasheet. It is not rated for extended industrial or automotive temperature ranges; for –40°C to +125°C operation, consider TLV2471IDR instead.
Does TLV2471CDR include a shutdown pin?
No, TLV2471CDR does not have a shutdown function. The TLV2470 and TLV2473 variants include SHDN pins; TLV2471CDR omits this feature to reduce pin count and simplify control logic in always-on applications.
What is the maximum capacitive load TLV2471CDR can drive stably?
TLV2471CDR remains stable with ≤10pF capacitive load directly at the output. For larger loads (e.g., ADC input capacitance), TI recommends adding a 20Ω–100Ω isolation resistor (RNULL) between the op-amp output and the load, as documented in Figure 42 of the SLOS232E datasheet.
Can TLV2471CDR operate from a 2.7V supply?
Yes, TLV2471CDR 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 input/output functionality - enabling direct use with single-cell Li-ion or alkaline batteries.
What is the input offset voltage drift over temperature for TLV2471CDR?
The TLV2471CDR exhibits a typical input offset voltage drift of 0.4μV/°C, as confirmed in the Electrical Characteristics table (αVIO parameter) of the SLOS232E datasheet. This low drift supports stable DC-coupled gain stages across its 0°C to +70°C operating range.
