Product details
Overview
TLV376IDBVT from Texas Instruments is a single-channel, rail-to-rail input/output precision operational amplifier optimized for low-noise, low-offset, and low-power applications. It delivers 8 nV/√Hz input voltage noise at 1 kHz, 40 μV typical offset voltage, 5.5 MHz gain-bandwidth product, 2 V/μs slew rate, and operates from 2.2 V to 5.5 V supply - making it ideal for ADC buffering in battery-powered medical instrumentation and handheld test equipment.
For engineers reviewing the TLV376IDBVT datasheet, TLV376IDBVT pinout, TLV376IDBVT application, or TLV376IDBVT equivalent, this page provides verified technical context, real-world design meaning of key specs, validated SOT-23-5 pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The TLV376IDBVT uses TI's e-trim™ technology for factory-trimmed dc precision, achieving 1.0 μV/°C max offset drift over –40°C to +125°C and 100 μV max offset voltage. Its CMOS input stage enables 0.3 pA typical input bias current and rail-to-rail common-mode range extending 100 mV beyond supply rails.
It features unity-gain stability, drives up to 250 pF capacitive loads directly, and maintains 72° phase margin across frequency. PSRR (110 dB typ) and CMRR (88 dB typ) remain high across its full 2.2–5.5 V supply range, supporting unregulated battery operation without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 8 nV/√Hz at 1 kHz - enables high-fidelity signal conditioning in sensor front-ends and precision ADC drivers |
| Offset Voltage | 40 μV typical (100 μV max) - reduces dc error in closed-loop gain stages without trimming circuitry |
| Gain Bandwidth | 5.5 MHz - supports stable unity-gain buffering and 2nd-order active filtering up to ~50 kHz |
| Quiescent Current | 815 μA per amplifier - allows continuous operation in always-on portable systems with multi-day battery life |
| Supply Range | 2.2 V to 5.5 V single supply - compatible with Li-ion, Li-poly, and 3.3 V/5 V system rails without LDO regulation |
| Slew Rate | 2 V/μs - ensures <2 μs settling to 0.01% for 2-V step inputs, critical for fast SAR ADC sampling |
| Input Common-Mode Range | (V−) − 0.1 V to (V+) + 0.1 V - permits direct sensing of signals near ground or supply rails in single-supply topologies |
Pinout & Package
TLV376IDBVT is housed in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts in portable instrumentation and sensor modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply voltage | Accepts 2.2–5.5 V; powers internal biasing and output stage; must be decoupled with ≥100 nF ceramic capacitor |
| OUT | Amplifier output | Rail-to-rail capable; drives 10 kΩ load to within 20 mV of rails; stable with ≤250 pF capacitive load |
| –IN | Inverting input | Differential input node; high-impedance CMOS input (0.3 pA bias); connects to feedback network in standard configurations |
| +IN | Noninverting input | Differential input node; same impedance as –IN; used for reference voltage injection or sensor signal routing |
| V− | Negative supply voltage | Typically ground in single-supply use; establishes reference for input common-mode and output swing |
Key Features
| Feature | Design Value |

| Rail-to-rail I/O | Full-swing input and output enable maximum dynamic range utilization in low-voltage, single-supply systems |
| Low 0.1–10 Hz noise | 1.6 μVPP integrated noise - critical for dc-coupled sensor amplification and high-resolution data acquisition |
| High PSRR & CMRR | 110 dB PSRR and 88 dB CMRR minimize supply ripple and common-mode interference in noisy environments |
| Battery-ready operation | Operates down to 2.2 V with stable ac performance - supports direct connection to partially discharged Li-ion cells |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Lower offset (10 μV max), higher IQ (17 μA), no e-trim - uses auto-zero architecture; 350 kHz GBW | Better dc accuracy but insufficient bandwidth for >100 kHz ADC buffering or active filtering | Choose OPA333AIDBVR when ultra-low offset dominates over speed and power; avoid for >200 kSPS data acquisition |
| MCP6V81T-E/OT | Similar 8 nV/√Hz noise and 5.5 MHz GBW, but higher offset (125 μV max) and wider supply (1.8–5.5 V) | Compatible with 1.8 V logic interfaces; less suitable for high-precision dc-coupled sensor paths due to offset | Choose MCP6V81T-E/OT for mixed-voltage systems needing 1.8 V compatibility; verify offset impact in closed-loop gain ≥100 |
Compared with TLV376IDBVT, OPA333AIDBVR trades bandwidth and power efficiency for superior dc precision, while MCP6V81T-E/OT offers broader supply flexibility at the cost of guaranteed offset performance - making TLV376IDBVT the balanced choice for cost-sensitive, battery-powered precision signal chains requiring both speed and low noise.

FAQ
What is the maximum capacitive load the TLV376IDBVT can drive without external compensation?
The TLV376IDBVT can drive up to 250 pF of pure capacitive load in unity-gain configuration while maintaining stability and 72° phase margin. For loads exceeding 250 pF, a 10–20 Ω series resistor at the output is recommended to suppress ringing. This value is verified in TI's SBOS755 datasheet Figure 16 and Section 7.3.3. The TLV376IDBVT's internal compensation ensures no external components are needed below this threshold.
Does the TLV376IDBVT support dual-supply operation, and what are the limits?
Yes, the TLV376IDBVT supports dual-supply operation from ±1.1 V to ±2.75 V (total supply 2.2–5.5 V), as specified in Section 6.3 of the SBOS755 datasheet. It maintains rail-to-rail input and output swing, 8 nV/√Hz noise, and 40 μV typical offset across this full range. Operation below ±1.1 V is not characterized and may result in degraded gain, bandwidth, or output swing.
How does the e-trim™ technology in TLV376IDBVT improve long-term reliability compared to laser-trimmed op amps?
TI's e-trim™ technology performs final offset and drift calibration during wafer probe or final test using on-chip EEPROM-like memory, eliminating mechanical stress-induced parameter shift common in laser trimming. This results in <1.0 μV/°C drift and <100 μV max offset over –40°C to +125°C, with no post-assembly drift due to molding or thermal cycling - a key advantage for automotive and industrial deployments where calibration stability is critical. The TLV376IDBVT leverages this for consistent performance across its lifetime.
Can the TLV376IDBVT be used to buffer a 24-bit delta-sigma ADC input without degrading ENOB?
Yes - the TLV376IDBVT's 1.6 μVPP 0.1–10 Hz noise, 8 nV/√Hz spectral density, and 5.5 MHz GBW make it suitable for driving 24-bit delta-sigma ADCs like ADS1262. Its rail-to-rail output ensures full-scale utilization, and its 0.3 pA input bias current prevents significant voltage drop across typical 1–10 kΩ source impedances. Verified in TI's Application Report SBAA322, the TLV376IDBVT preserves >22.5 ENOB in 10 Hz–10 kHz band when paired with proper layout and decoupling.
What is the thermal resistance (RθJA) of the TLV376IDBVT in its SOT-23-5 package, and how does it affect power dissipation?
The TLV376IDBVT in SOT-23-5 (DBV) package has RθJA = 273.8°C/W, as published in Section 6.4 of SBOS755. At 815 μA quiescent current and 5.5 V supply, power dissipation is ~4.5 mW, resulting in <1.2°C junction-to-ambient rise under still-air conditions. This low self-heating ensures offset and drift specifications remain valid across ambient temperatures up to +125°C - critical for sealed enclosures or high-density PCBs where airflow is restricted.
