Product details
Overview
TLV2471CDBVT 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 - enabling precision signal conditioning in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2471CDBVT datasheet, TLV2471CDBVT pinout, TLV2471CDBVT application, or TLV2471CDBVT equivalent, this page provides verified technical context, SOT23-5 package mapping, rail-to-rail I/O behavior under load, shutdown current specs (350nA/ch @ 3V), and real-world design implications for low-voltage data acquisition circuits.
Technical Context
The TLV2471CDBVT employs a CMOS input stage with 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), enabling full dynamic range utilization in single-supply systems. Its output stage supports ±10mA at 180mV from rails and ±35mA at 500mV off rails, resolving a key limitation of legacy micropower op-amps.
It features no internal shutdown functionality - unlike TLV2470/2473/2475 - confirmed by absence of SHDN pin in DBV (SOT23-5) pinout and omission from shutdown current tables in the datasheet. The device operates across 0°C to +70°C (C-suffix) and is fully specified at 3V and 5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct operation from Li-ion (3.0–4.2V), 3.3V logic, and 5V systems without regulation. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~280kHz with phase margin >61°. |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit ADC front-end at room temperature. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly (e.g., analog multiplexer inputs, LED bias, DAC buffers). |
| Supply Current per Channel | 600μA (typ @ 3V) - allows 10+ channels in <6mA total system bias for portable instrumentation. |
| Input Bias Current | 2.5pA (typ) - permits use with high-impedance sources (e.g., pH electrodes, piezoelectric sensors) without significant DC error. |
| Common-Mode Input Range | 0V to VDD - accepts signals from ground to supply rail, eliminating level-shifting in single-supply sensor interfaces. |
Pinout & Package
SOT23-5 package (DBV): 2.9mm × 1.6mm × 1.0mm body, gull-wing leads, moisture sensitivity level 1, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail swing; capable of ±35mA into 500mV headroom - suitable for driving capacitive loads ≥10pF with series RNULL ≥20Ω. |
| 2 - IN− | Inverting input | High-impedance CMOS node; 2.5pA bias current enables precision differential sensing with matched feedback networks. |
| 3 - IN+ | Non-inverting input | Accepts signals from 0V to VDD; used for unity-gain buffers, active filters, and reference voltage followers. |
| 4 - GND | Analog ground reference | Must be low-impedance connection to system AGND plane; separates from digital ground to minimize noise coupling. |
| 5 - VDD | Positive supply | Accepts 2.7–6V; requires local 0.1μF ceramic decoupling within 5mm of pin to maintain stability at 2.8MHz GBW. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3V or 5V supply in single-ended configurations - e.g., direct interfacing to SAR ADCs with VREF = VDD. |
| Ultra-low input bias current (2.5pA) | Minimizes voltage error across high-value feedback resistors (>1MΩ), critical for transimpedance amplifiers in photodiode circuits. |
| High output drive (±35mA @ 500mV) | Eliminates need for external buffer stages when driving low-impedance loads like relay coils, analog switches, or terminated transmission lines. |
| Low supply current (600μA/ch) | Supports always-on sensor monitoring in energy-harvesting nodes with sub-10μA average system sleep current. |
| Specified at 3V and 5V | Guarantees performance across common battery and regulated supply voltages - no derating required for 3.3V microcontroller-based designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Lower input offset (100μV typ), higher GBW (10MHz), but 1mA supply current - 67% higher quiescent power. | Preferred where speed >2.8MHz or offset <150μV is mandatory; less suitable for multi-channel <1mA budget designs. | Select OPA316IDBVR only if 10MHz bandwidth or sub-150μV offset is required - otherwise TLV2471CDBVT offers better power/performance trade-off. |
| MCP6001T-E/OT | Same SOT23-5 package, lower cost, but 1MHz GBW, ±7mA output drive, and 4.5mV max offset - significantly reduced AC performance and drive strength. | Suitable for basic voltage followers or low-speed comparators; not viable for 20kHz+ sensor signal chains or 10mA+ loads. | Choose MCP6001T-E/OT for cost-sensitive, non-critical DC-coupled buffers - avoid where 2.8MHz GBW or ±35mA drive is needed. |
Compared with OPA316IDBVR and MCP6001T-E/OT, the TLV2471CDBVT uniquely balances 2.8MHz bandwidth, ±35mA output drive, and 600μA supply current in SOT23-5 - making it optimal for space-constrained, battery-powered signal chains requiring both precision and drive capability.

FAQ
Does TLV2471CDBVT include a shutdown pin?
No, TLV2471CDBVT does not have a shutdown function. Unlike TLV2470 (SOT23-6 with SHDN) or TLV2473 (MSOP-10 with SHDN), the TLV2471CDBVT uses the SOT23-5 package with pins dedicated solely to power, input, and output - confirmed by its pinout diagram and absence from all shutdown current specifications in the datasheet.
What is the maximum capacitive load TLV2471CDBVT can drive stably?
The TLV2471CDBVT remains stable with capacitive loads up to 10pF directly at the output. For loads exceeding 10pF (e.g., PCB traces, ADC input capacitance), a series null resistor (RNULL ≥20Ω) must be placed between the output pin and the load - as specified in Figure 42 of the datasheet - to maintain phase margin >61° and prevent oscillation.
Can TLV2471CDBVT operate from a 2.5V supply?
No, TLV2471CDBVT has a minimum rated supply voltage of 2.7V per Absolute Maximum Ratings and Recommended Operating Conditions tables. Operation below 2.7V is not characterized or guaranteed - parameters like GBW, output drive, and input offset may degrade unpredictably at 2.5V.
Is TLV2471CDBVT pin-compatible with other SOT23-5 op-amps like MCP6001?
TLV2471CDBVT shares the standard SOT23-5 pinout (OUT/IN−/IN+/GND/VDD), making it physically compatible with MCP6001T-E/OT and similar devices. However, electrical differences - including 2.8MHz vs 1MHz GBW, ±35mA vs ±7mA drive, and 250μV vs 4.5mV max offset - require circuit validation before substitution.
What is the thermal resistance (θJA) of TLV2471CDBVT in SOT23-5 package?
The TLV2471CDBVT in DBV (SOT23-5) package has a junction-to-ambient thermal resistance (θJA) of 324.1°C/W, as specified in the Dissipation Rating Table. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves significantly with copper pour and thermal vias beneath the pad.
