Product details
Overview
TLV271IDBVTG4 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 TLV271IDBVTG4 datasheet, TLV271IDBVTG4 pinout, TLV271IDBVTG4 application, or TLV271IDBVTG4 equivalent, key selection criteria include rail-to-rail output swing at low supply voltages, ultra-low input bias current (1 pA), CMOS input stage compatibility with high-impedance sensors, and SOT-23-5 packaging for space-constrained designs.
Technical Context
The TLV271IDBVTG4 employs a CMOS input stage enabling 1 pA input bias current and 1000 GΩ differential input resistance, making it suitable for high-impedance sensor interfaces such as photodiode or thermistor front-ends. Its rail-to-rail output stage supports full dynamic range utilization down to 2.7 V supply, critical for Li-ion powered systems and MSP430 microcontroller interfacing.
It achieves 3-MHz gain-bandwidth product with only 550 µA quiescent current, delivering 2.4 V/µs slew rate at 5 V supply. The device is fully specified across –40°C to +125°C and supports both single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) operation without performance degradation.
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), 5-V rails, and ±5-V analog subsystems |
| Bandwidth (UGBW) | 3 MHz - supports audio-band filtering, motor control feedback, and fast sensor response up to ~50 kHz closed-loop |
| Slew Rate | 2.4 V/µs - ensures faithful reproduction of 1-Vpp signals up to ~380 kHz without distortion |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sensor circuits (e.g., >10 MΩ source impedance) |
| Input Noise Voltage | 39 nV/√Hz - maintains SNR integrity in precision DC-coupled amplification of low-level transducer outputs |
| Operating Temperature | –40°C to +125°C - qualified for industrial and automotive under-hood environments without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV271IDBVR | Same silicon, tape-and-reel packaging (no G4 suffix); identical electrical specs and thermal performance | No functional difference; selected for automated SMT assembly vs. sample evaluation | Choose TLV271IDBVR for volume production; TLV271IDBVTG4 is same device in cut-tape format with TI's green marking |
| TLV2371IDBVT | Includes shutdown pin (active-low); 550 µA quiescent current in active mode; 100 nA in shutdown | Required when system-level power gating or deep-sleep modes demand sub-µA standby current | Use TLV2371IDBVT only if explicit shutdown control is needed; otherwise TLV271IDBVTG4 offers simpler layout and lower cost |
Compared with TLV271IDBVR, TLV271IDBVTG4 offers identical performance in cut-tape form for prototyping and low-volume builds; compared with TLV2371IDBVT, it lacks shutdown but provides lower BOM count and eliminates risk of unintended disable during transient conditions.

FAQ
What is the maximum supply voltage rating for TLV271IDBVTG4?
The absolute maximum supply voltage for TLV271IDBVTG4 is 16.5 V, with recommended operation up to 16 V. Exceeding this may cause permanent damage. The device is fully specified from 2.7 V to 16 V, supporting single-supply operation (e.g., 3.3 V, 5 V, 12 V) and split supplies (±1.35 V to ±8 V). Always observe derating guidelines above 125°C junction temperature.
Does TLV271IDBVTG4 support rail-to-rail input?
No, TLV271IDBVTG4 features rail-to-rail *output* only. Its common-mode input voltage range is 0 V to VDD − 1.35 V, meaning the inputs cannot swing to the positive rail. For true rail-to-rail input capability, consider TI's TLV2461 or OPA333 families. TLV271IDBVTG4's input stage is optimized for high impedance and low bias current-not full-rail input coverage.
What is the typical input offset voltage for TLV271IDBVTG4?
The typical input offset voltage for TLV271IDBVTG4 is 5 mV at 25°C, with a maximum of 7 mV across the full –40°C to +125°C temperature range. This value is measured under standard conditions (VDD = 2.7 V/5 V/±5 V, RL = 10 kΩ, VO = VDD/2). Offset voltage drift is 2 µV/°C, contributing predictably to total error in precision DC applications.
Can TLV271IDBVTG4 drive capacitive loads directly?
TLV271IDBVTG4 can drive capacitive loads ≤10 pF stably. For loads >10 pF (e.g., long traces, ADC input capacitance), TI recommends adding a series resistor (RNULL ≥20 Ω) between the output and load to maintain phase margin >65° and prevent ringing or oscillation. This is documented in Section 8.3.3 of the TLV271 datasheet (SLOS351E).
Is TLV271IDBVTG4 RoHS-compliant and lead-free?
Yes, TLV271IDBVTG4 is RoHS-compliant and lead-free. The "G4" suffix in the part number denotes TI's green packaging standard, which meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and IPC/JEDEC J-STD-033 handling requirements. Full compliance documentation, including material declarations and test reports, is available via TI's Quality & Environmental Information portal.
