Product details
Overview
TLV9151IDBVR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for precision industrial signal conditioning. It delivers ±125 µV offset voltage, 4.5-MHz gain-bandwidth product, 20 V/µs slew rate, and 10.5 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity amplification in low-voltage, low-noise sensor front-ends and current-sensing circuits.
For engineers reviewing the TLV9151IDBVR datasheet, TLV9151IDBVR pinout, TLV9151IDBVR application, or TLV9151IDBVR equivalent, this page provides verified specifications, validated SOT-23-5 pin mapping, real-world use cases in factory automation and professional audio, and two confirmed alternative op amps with documented functional trade-offs.
Technical Context
The TLV9151IDBVR implements a precision bipolar-input architecture with EMI/RFI filtering on both inputs, supporting differential and common-mode input voltages extending to the supply rails. Its 120 dB CMRR and ±0.3 µV/°C offset drift ensure stable DC accuracy across temperature in closed-loop sensing applications.
It operates from 2.7 V to 16 V (±1.35 V to ±8 V), delivers ±75 mA output current, and achieves 0.01% settling in 2.5 µs under 10-V step conditions - making it suitable for multiplexed data acquisition where fast settling and rail-to-rail swing are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4.5 MHz - supports stable unity-gain and moderate-gain configurations up to ~100 kHz without phase margin degradation |
| Input offset voltage | ±125 µV (typ) - enables sub-1-mV error in 100× gain current-sense amplifiers at room temperature |
| Slew rate | 20 V/µs - allows full-scale 10-V output transitions in ≤0.5 µs, supporting fast transient response in control loops |
| Input voltage noise | 10.5 nV/√Hz @ 1 kHz - preserves SNR in microphone preamps and strain-gauge interfaces with <10-kΩ source impedances |
| Quiescent current | 560 µA per amplifier - enables always-on operation in battery-powered condition monitoring nodes |
| Supply range | 2.7 V to 16 V - interoperates with 3.3-V microcontrollers and 12-V industrial buses without level-shifting |
| CMRR | 120 dB (min) - rejects >99.999% of common-mode interference in high-side current sensing |
Pinout & Package
SOT-23-5 package (2.90 mm × 1.60 mm body size), surface-mount, lead-free, RoHS-compliant. Thermal resistance RθJA = 185.7°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplifier output node; rail-to-rail swing supports direct interface to SAR ADC references or analog comparators |
| 2 - V– | Negative supply | Lowest potential rail; must be connected to system ground or negative supply; thermal pad (if present) ties here |
| 3 - IN+ | Noninverting input | High-impedance (6 TΩ || 1 pF) node; accepts signals from V– – 0.1 V to V+ + 0.1 V |
| 4 - IN– | Inverting input | Differential pair input; matched to IN+ for <10 µV input offset contribution from layout asymmetry |
| 5 - V+ | Positive supply | Highest potential rail; supplies internal bias circuitry and output stage; decoupling capacitor required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 3.3-V microcontroller I/O) without clipping |
| EMI/RFI filters on input pins | Reduces susceptibility to GSM, Wi-Fi, and switching regulator noise in factory-floor environments |
| Low bias current (±10 pA) | Minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance stages) |
| Wide common-mode range | Supports direct connection to shunt resistors placed on either side of load (high-side or low-side current sensing) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA391DBVR | Lower noise (4.6 nV/√Hz), higher GBW (10 MHz), but higher IQ (1.2 mA); no integrated EMI filters | Better suited for high-frequency, low-noise applications (e.g., ultrasound receivers); less robust in electrically noisy industrial settings | Select OPA391DBVR when bandwidth and noise dominate; choose TLV9151IDBVR when EMI immunity and lower power are prioritized |
| LMV721IDBVR | Higher offset (±300 µV), lower GBW (1.5 MHz), no shutdown pin; same SOT-23-5 footprint | Cost-optimized for non-critical DC performance; lacks rail-to-rail input and EMI filtering | LMV721IDBVR offers pin-compatible drop-in replacement only for legacy designs where ±300 µV offset is acceptable |

FAQ
What is the maximum operating temperature range for TLV9151IDBVR?
The TLV9151IDBVR is specified from –40°C to +125°C ambient temperature, with validated electrical performance across this full industrial range. Its ±0.3 µV/°C offset drift and stable 4.5-MHz GBW make it suitable for deployment in uncontrolled environments such as motor control enclosures and outdoor instrumentation housings. All parameters in the official datasheet (SBOS986E) are guaranteed over this interval.
Does TLV9151IDBVR include a shutdown function?
No, the TLV9151IDBVR (SOT-23-5 DBV package) does not include a shutdown pin. Shutdown functionality is only available in the TLV9151S variant (SOT-23-6 package, pin 5 = SHDN). The TLV9151IDBVR is a standard single-channel op amp with five pins: OUT, V–, IN+, IN–, and V+. Confusion may arise from the family datasheet covering multiple variants, but the DBV suffix denotes the non-shutdown version.
Can TLV9151IDBVR drive a 1000-pF capacitive load stably?
Yes, TLV9151IDBVR is characterized to drive up to 1000 pF capacitive load without external compensation or phase-margin degradation. This capability is explicitly tested and guaranteed in the Electrical Characteristics table (CLOAD = 1000 pF). It enables direct interfacing to SAR ADC inputs, long PCB traces, and filter networks without risk of oscillation - a key advantage over many general-purpose op amps requiring isolation resistors.
What is the typical input bias current of TLV9151IDBVR?
The typical input bias current of TLV9151IDBVR is ±10 pA, measured at 25°C with VCM = V–. This ultra-low value minimizes voltage errors in high-impedance circuits such as photodiode transimpedance amplifiers, piezoelectric sensor buffers, and precision voltage dividers. The input structure uses precision bipolar technology with guarded inputs to achieve this performance while retaining low noise and high speed.
Is TLV9151IDBVR RoHS-compliant and lead-free?
Yes, TLV9151IDBVR is RoHS-compliant and lead-free. It meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 rating and is qualified for reflow soldering per IPC/JEDEC J-STD-020. The SOT-23-5 (DBV) package uses matte tin lead finish and complies with EU Directive 2011/65/EU and China RoHS II. Full compliance documentation is available via Texas Instruments' product folder and material declarations.
