Product details
Overview
TLV2471IDBVT 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 a 2.7V–6V supply range - enabling precision signal conditioning in battery-powered sensor interfaces and portable medical devices.
For engineers reviewing the TLV2471IDBVT datasheet, TLV2471IDBVT pinout, TLV2471IDBVT application, or TLV2471IDBVT equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The TLV2471IDBVT employs a CMOS input stage delivering 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), paired with a robust output stage capable of ±35mA sourcing/sinking while maintaining rail-to-rail swing. Its 2.8MHz gain-bandwidth product and 1.5V/μs slew rate support stable unity-gain operation with capacitive loads up to 1000pF when properly compensated.
No shutdown functionality is integrated - unlike TLV2470/2473/2475 variants - making it suitable for always-on signal paths where low quiescent current (600μA) and minimal turn-on latency (5μs) are prioritized over power gating. It is fully specified over –40°C to +125°C and operates down to 2.7V, supporting industrial-grade analog front-ends.
Key Specifications

|---|---|
| Supply Voltage Range | 2.7V to 6V - enables direct operation from single Li-ion cells or 3.3V/5V rails without regulation. |
| Gain-Bandwidth Product | 2.8MHz - supports closed-loop gains up to ~28 at 100kHz with stable phase margin. |
| Input Offset Voltage (typ) | 250μV - ensures ≤0.5mV error in 2V full-scale 12-bit systems without trimming. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly, eliminating external buffers in DAC output stages. |
| Supply Current (per channel) | 600μA - achieves micropower operation while retaining >2MHz bandwidth, outperforming legacy rail-to-rail op-amps. |
| Input Bias Current | 2.5pA - minimizes voltage error across high-impedance sensor sources (e.g., pH electrodes, photodiodes). |
| Common-Mode Input Range | 0V to VDD - accepts signals spanning full supply, critical for single-supply instrumentation amplifiers. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9mm × 1.6mm × 1.0mm body, surface-mount, tape-and-reel compatible. Thermal resistance θJA = 324.1°C/W; rated power dissipation 385mW at TA ≤ +25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing and ±35mA drive; requires series resistor ≥20Ω for >10pF capacitive loads. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; connects to feedback network in standard configurations (e.g., inverting amp, transimpedance). |
| 3 (IN+) | Non-inverting input | High-impedance CMOS node; accepts DC-coupled sensor signals or filtered references within 0V–VDD range. |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load current; must be low-impedance and separated from digital ground. |
| 5 (VDD) | Positive supply | Accepts 2.7V–6V; bypass capacitor (0.1μF ceramic) required within 5mm for stability and noise immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.1μV/°C offset drift vs. TLV2471IDBVT's 0.4μV/°C; 350nA supply current (lower), but only 350kHz GBW. | Better for DC-critical applications (e.g., precision weigh scales); unsuitable for >100kHz signal chains due to limited bandwidth. | Select OPA333AIDBVR when long-term offset stability dominates speed requirements; avoid when >500kHz closed-loop bandwidth is needed. |
| MCP6001T-E/OT | Lower cost; 100μA supply current, but only 1MHz GBW and ±6mA output drive; input bias current 1pA (slightly lower). | Targeted at cost-sensitive, low-speed applications (e.g., basic voltage monitoring); cannot drive heavy loads or support fast settling. | Choose MCP6001T-E/OT for non-critical, low-bandwidth uses where budget constraints outweigh performance needs; not recommended for sensor front-ends requiring >20mA drive. |
Compared with OPA333AIDBVR and MCP6001T-E/OT, TLV2471IDBVT uniquely balances 2.8MHz bandwidth, ±35mA drive, and 600μA consumption - making it the only option among the three capable of driving 100Ω loads at >100kHz while maintaining rail-to-rail operation across industrial temperatures.

FAQ
What is the maximum capacitive load the TLV2471IDBVT can drive without oscillation?
The TLV2471IDBVT maintains stability with up to 1000pF load capacitance when configured as a unity-gain follower with RL = 10kΩ, as confirmed by phase margin measurements in the datasheet (Figure 18). For loads >10pF, TI recommends adding a 20Ω–100Ω series resistor (RNULL) between the output pin and the capacitive load to preserve phase margin and prevent ringing - a design practice validated in Figure 42 of the TLV2471IDBVT datasheet.
Does the TLV2471IDBVT include a shutdown pin?
No, the TLV2471IDBVT does not include a shutdown pin. Unlike the TLV2470, TLV2473, and TLV2475 variants in the same family, the TLV2471IDBVT is a single-channel amplifier in SOT-23-5 packaging with no SHDN terminal. Its pinout consists solely of OUT, IN−, IN+, GND, and VDD - making it suitable for always-on signal paths where low-latency turn-on and consistent quiescent current are required.
What is the typical input offset voltage drift over temperature for TLV2471IDBVT?
The TLV2471IDBVT has a typical input offset voltage drift (αVIO) of 0.4μV/°C, as specified in the Electrical Characteristics table (page 4 of SLOS232E). This value is measured across the full industrial temperature range (–40°C to +125°C) and applies to both C- and I-suffix devices. At 125°C, this results in a worst-case additional offset of ~66μV beyond the 250μV room-temperature typical value - well within tolerance for most 12-bit precision applications.
Can TLV2471IDBVT operate from a 2.5V supply?
No, the TLV2471IDBVT has a minimum recommended supply voltage of 2.7V, as stated in the Recommended Operating Conditions table (page 4). Operation at 2.5V falls outside the specified range and may result in degraded parameters including reduced output swing, increased input offset voltage, and unstable biasing - particularly at temperature extremes. Designs requiring 2.5V operation should consider alternatives such as the TLV9001 or OPA316, which are explicitly characterized down to 1.8V.
What is the thermal resistance (θJA) of the TLV2471IDBVT in its SOT-23-5 package?
The TLV2471IDBVT in the DBV (SOT-23-5) package has a junction-to-ambient thermal resistance (θJA) of 324.1°C/W, as listed in the Dissipation Rating Table (page 3 of SLOS232E). This value assumes standard JEDEC 2-layer board conditions. With a maximum junction temperature of +150°C and ambient temperature of +85°C, the maximum allowable power dissipation is approximately 200mW - consistent with the 385mW rating at TA ≤ +25°C, derated linearly per the θJA specification.
