Product details
Overview
TLV271IDBVRG4 from Texas Instruments is a single-channel, rail-to-rail output operational amplifier optimized for low-power, wide-bandwidth signal conditioning in battery-powered and industrial systems. It delivers 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, 550 µA supply current per channel, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V over –40°C to +125°C. It is used in smoke detectors for sensor signal amplification with minimal power draw.
For engineers reviewing the TLV271IDBVRG4 datasheet, TLV271IDBVRG4 pinout, TLV271IDBVRG4 application, or TLV271IDBVRG4 equivalent, key selection considerations include rail-to-rail output swing at low supply voltages, ultra-low input bias current (1 pA), thermal performance in SOT-23 packaging, and compatibility with Li-ion and MSP430-based systems.
Technical Context
The TLV271IDBVRG4 employs a CMOS input stage enabling high-impedance sensor interfacing and low input bias current (1 pA), while its rail-to-rail output stage supports full dynamic range utilization down to 2.7 V supply. Its 3-MHz gain-bandwidth product and 2.4 V/µs slew rate are maintained across 2.7–16 V operation.
It is fully specified for both single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) configurations, with common-mode input range extending from GND to VDD − 1.35 V. Input offset voltage is 500 µV max (typical 5 mV), and PSRR is 70–80 dB across supply variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - enables direct use with Li-ion cells (3.0–4.2 V), dual AA/AAA (3 V), and industrial 12-V rails without regulation. |
| Bandwidth (UGBW) | 3 MHz - supports audio-frequency filtering, motor control feedback, and sensor signal conditioning up to ~50 kHz closed-loop. |
| Slew Rate | 2.4 V/µs - ensures <2 µs settling for 1-V step with 0.1% accuracy, critical for fast pulse amplification in smoke detector analog front-ends. |
| Supply Current | 550 µA per channel - reduces quiescent power to <1.5 mW at 2.7 V, extending battery life in portable instruments and building automation sensors. |
| Input Bias Current | 1 pA - preserves signal integrity when amplifying high-impedance sources like photodiode or piezoelectric transducers. |
| Input Voltage Noise | 39 nV/√Hz - maintains SNR >70 dB in low-level sensor interfaces (e.g., CO detection circuits) at 1 kHz. |
| Rail-to-Rail Output | Swings within 135 mV of rails at 1 mA load - maximizes ADC input range utilization in 8-bit/10-bit microcontroller systems. |
Pinout & Package
TLV271IDBVRG4 is packaged in a 5-pin SOT-23 (DBV) surface-mount package measuring 2.90 mm × 1.60 mm × 1.15 mm, optimized for space-constrained PCB layouts in portable and embedded applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified signal node; capable of sourcing/sinking ≥4 mA while maintaining rail-to-rail swing; requires series resistor for >10 pF capacitive loads. |
| 2 - GND | Negative Supply / Ground | Reference return path for single-supply operation; must be low-impedance to minimize noise coupling into high-Z inputs. |
| 3 - IN+ | Noninverting Input | High-impedance CMOS node (1000 GΩ); connects to sensor reference or signal source; sensitive to ESD and layout parasitics. |
| 4 - IN− | Inverting Input | High-impedance CMOS node; forms feedback network with external resistors; matched trace routing recommended for precision DC apps. |
| 5 - VDD | Positive Supply | Primary power input; requires local 100-nF ceramic decoupling to GND within 2 mm to stabilize high-frequency PSRR performance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full utilization of 2.7–16 V supply range-critical for maximizing dynamic range in 3.3-V microcontroller ADC interfaces. |
| 1 pA input bias current | Permits direct connection to megohm-range sensors (e.g., gas-sensing electrochemical cells) without significant offset error. |
| 3-MHz bandwidth at 550 µA | Delivers 5× higher speed than comparable micropower opamps (e.g., LPV821), enabling faster loop response in motor control feedback. |
| –40°C to +125°C operation | Qualified for industrial and automotive under-hood environments; thermal resistance RθJA = 221.7°C/W in SOT-23 limits max ambient to ~85°C at full load. |
| CMOS input stage | Eliminates BJT base-current errors and enables stable DC-coupled designs with high-value feedback networks (>1 MΩ). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2371IDBVR | Includes shutdown mode (IQ = 50 nA off-state); identical bandwidth (3 MHz), but lower slew rate (1.7 V/µs) and higher input offset (1.5 mV typ). | Better suited for intermittent-sampling systems requiring deep sleep (e.g., wireless PIR sensors), but less ideal for continuous high-fidelity signal paths. | Select TLV2371IDBVR only if system-level power budget mandates sub-µA shutdown current; otherwise TLV271IDBVRG4 offers superior dynamic performance. |
| OPA316IDBVR | Higher precision: 100 µV max VIO, 11 MHz GBW, 6 V/µs SR, but 1 mA IQ; not rated for >125°C. | Targeted at high-accuracy instrumentation (e.g., medical sensors), not battery-limited industrial edge nodes. | Choose OPA316IDBVR only when offset and speed outweigh quiescent power constraints; TLV271IDBVRG4 remains optimal for cost-sensitive, thermally demanding, low-power designs. |
Compared with TLV2371IDBVR and OPA316IDBVR, TLV271IDBVRG4 uniquely balances 3-MHz bandwidth, 550-µA quiescent current, rail-to-rail output, and extended temperature capability-making it the preferred choice for industrial-grade battery-powered signal chains where power, speed, and ruggedness intersect.

FAQ
What is the operating temperature range of the TLV271IDBVRG4?
The TLV271IDBVRG4 is rated for industrial operation from –40°C to +125°C, verified per TI's SLOS351E datasheet. This range applies to all electrical specifications including input offset voltage, bandwidth, and supply current-making TLV271IDBVRG4 suitable for under-hood automotive, outdoor building sensors, and industrial motor controls where ambient extremes occur.
Does the TLV271IDBVRG4 support rail-to-rail input?
No, the TLV271IDBVRG4 does not feature rail-to-rail input. Its common-mode input voltage range is specified as 0 V to VDD − 1.35 V. For example, at 2.7 V supply, valid input range is 0 V to 1.35 V-not the full 0–2.7 V span. TLV271IDBVRG4 provides rail-to-rail *output* only, as confirmed in Section 1 (Features) and Section 3 (Description) of the official datasheet.
What is the maximum capacitive load the TLV271IDBVRG4 can drive directly?
The TLV271IDBVRG4 is stable with ≤10 pF capacitive load at the output. For loads exceeding 10 pF-including PCB traces, cable capacitance, or ADC input capacitance-TI recommends adding a series resistor (RNULL ≥20 Ω) between the TLV271IDBVRG4 output and the load to preserve phase margin and prevent oscillation, as detailed in Section 8.3.3 and Figure 26 of the datasheet.
Is the TLV271IDBVRG4 pin-compatible with the TLC271?
Yes, TLV271IDBVRG4 is pin-compatible with TLC271 in the same SOT-23 (DBV) package: both share identical pin 1 (OUT), pin 2 (GND), pin 3 (IN+), pin 4 (IN−), and pin 5 (VDD) assignments. However, TLV271IDBVRG4 improves upon TLC271 with rail-to-rail output, lower supply current (550 µA vs. 675 µA), and wider supply range (2.7–16 V vs. 3–16 V).
What is the typical input offset voltage of the TLV271IDBVRG4?
The typical input offset voltage of TLV271IDBVRG4 is 5 mV at 25°C, with a maximum of 500 µV for the "I" grade (industrial temperature range). This value is measured under standard conditions (VDD = 2.7/5/±5 V, RL = 10 kΩ, VO = VDD/2, RS = 50 Ω) and appears in Section 7.6 (DC Characteristics) of the SLOS351E datasheet.
