Product details
Overview
TLV171IDBVT from Texas Instruments is a single-channel, 36-V rail-to-rail output operational amplifier optimized for cost-sensitive industrial and battery-powered systems. It delivers 3 MHz gain bandwidth, 16 nV/√Hz input voltage noise, ±1 μV/°C offset drift, 525 µA quiescent current per amplifier, and operates from 2.7 V to 36 V single supply - enabling precision signal conditioning in AC-DC converters and TFT-LCD drive circuits.
For engineers reviewing the TLV171IDBVT datasheet, TLV171IDBVT pinout, TLV171IDBVT application, or TLV171IDBVT equivalent, this page provides verified specifications, SOT-23-5 package details, real-world use cases in transducer interfaces and power modules, and validated alternative op amps with documented functional and application differences.
Technical Context
The TLV171IDBVT uses a P-channel input stage enabling rail-to-rail input operation down to 100 mV below V− and within 2 V of V+, with no phase reversal beyond common-mode limits. Its EMI-hardened architecture includes RFI-filtered inputs and internal phase-reversal protection circuitry that clamps output instead of inverting when overdriven.
Specified across –40°C to +125°C and 2.7 V–36 V supply range, it maintains 105 dB CMRR and PSRR, 94 dB open-loop gain, and unity-gain stability with up to 200 pF capacitive load - supporting robust performance in noisy industrial environments without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 2.7 V to 36 V single supply (±1.35 V to ±18 V dual) - supports wide-input industrial power rails and battery voltage decay. |
| Gain Bandwidth Product | 3.0 MHz - enables stable closed-loop operation at G = +1 with ≤200 pF load and fast settling for 12-bit precision. |
| Input Voltage Noise | 16 nV/√Hz at 1 kHz - low-noise performance critical for high-resolution transducer amplification and active filter stages. |
| Offset Drift | ±1 μV/°C (typical) - ensures <±3.0 mV total offset variation over –40°C to +125°C, reducing calibration burden in embedded systems. |
| Quiescent Current | 525 µA per amplifier - enables multi-channel sensing in battery-powered instruments with extended runtime. |
| Rail-to-Rail Output | Swings to within 90 mV of V− and 160 mV of V+ at ±18 V - maximizes dynamic range in single-supply data acquisition front ends. |
| Common-Mode Range | V− − 0.1 V to V+ − 2 V - allows direct interfacing with sensors operating near ground or high-side references. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Output | Amplified signal node; rail-to-rail capable; drives 10 kΩ loads with <160 mV headroom to V+. |
| 2: V− | Negative Supply | Lowest potential reference; input common-mode extends 100 mV below this rail. |
| 3: +IN | Noninverting Input | High-impedance (10¹² Ω || 3 pF) node; accepts signals down to V− − 0.1 V. |
| 4: −IN | Inverting Input | High-impedance node; matched bias current (±10 pA) minimizes offset in precision configurations. |
| 5: V+ | Positive Supply | Highest potential reference; supports up to 36 V; ESD-protected (±4 kV HBM). |
Key Features
| Feature | Design Value |
|---|---|
| EMI-hardened inputs with RFI filtering | Reduces susceptibility to radiated RF interference in motor drives and power module control loops. |
| No phase reversal under overdrive | Prevents catastrophic output inversion in noninverting sensor interfaces when input exceeds V+ − 2 V. |
| Unity-gain stable with 200 pF load | Eliminates need for external isolation resistors in capacitive-load applications like LCD column drivers. |
| Low input bias current (10 pA) | Enables high-impedance source interfacing (e.g., piezoelectric transducers) without significant DC error. |
| Extended temperature range (–40°C to +125°C) | Validated operation in automotive engine control units and industrial inverters without derating. |
Applications
| Transducer Signal Conditioning | AC-DC Converter Feedback |
|---|---|
Use Scenario: Amplifying low-level mV outputs from strain gauges, thermopiles, or pressure sensors in factory automation equipment. IC Role / Device Role / Timing Role: Precision instrumentation amplifier front end with rail-to-rail output driving 12-bit ADC reference buffers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA192IDBVT | Higher precision: 5 µV max offset, 0.2 µV/°C drift, 5.5 MHz GBW, but 1.3 mA IQ - 2.5× higher quiescent current. | Better suited for high-accuracy data acquisition where power is secondary to offset stability. | Select OPA192IDBVT only when sub-10 µV offset and <0.5 µV/°C drift are mandatory; TLV171IDBVT remains optimal for cost- and power-constrained designs. |
| LMV321IDBVR | Lower voltage: 2.7 V–5.5 V supply, 1 MHz GBW, 65 µA IQ, but only 85 dB CMRR and no EMI hardening. | Targeted at low-voltage consumer electronics; lacks industrial-grade noise immunity and temperature range. | Choose LMV321IDBVR only for battery-powered consumer devices with <5.5 V rails and minimal EMI exposure; TLV171IDBVT is required for 12–36 V industrial systems. |
Compared with OPA192IDBVT and LMV321IDBVR, TLV171IDBVT uniquely balances 36-V operation, EMI resilience, 1 µV/°C drift, and 525 µA power consumption - making it the only validated choice for cost-sensitive, wide-supply industrial signal chains requiring robustness across –40°C to +125°C.

FAQ
What is the maximum capacitive load the TLV171IDBVT can drive without oscillation?
The TLV171IDBVT is unity-gain stable with capacitive loads up to 200 pF, as confirmed in the SBOS783 datasheet Section 6.7 and Figure 14–15. This eliminates the need for external isolation resistors in applications like TFT-LCD column drivers or active filters where output capacitance exceeds typical PCB trace values. For loads >200 pF, a series resistor (e.g., 50 Ω) between TLV171IDBVT output and the load restores stability while maintaining signal integrity.
Does the TLV171IDBVT support true rail-to-rail input operation?
The TLV171IDBVT supports rail-to-rail input operation down to 100 mV below V− and up to V+ − 2 V for full-specified performance, as stated in Section 7.4.1 of the SBOS783 datasheet. It can accept inputs up to V+ + 0.1 V, but with degraded parameters (e.g., increased offset) within 2 V of V+. This enables direct interfacing with grounded sensors and high-side references without level-shifting circuitry.
What is the guaranteed operating temperature range for TLV171IDBVT?
The TLV171IDBVT is fully specified and tested from –40°C to +125°C, with electrical characteristics (e.g., offset drift, CMRR, PSRR) validated across this range per Section 6.3 and 6.7 of SBOS783. Absolute maximum ratings extend to –55°C to +150°C, but parametric performance is not guaranteed outside the –40°C to +125°C operating range.
How does the EMI-hardening feature of TLV171IDBVT improve system reliability?
The TLV171IDBVT integrates RFI-filtered inputs and internal EMI suppression circuitry, reducing sensitivity to radiated RF energy (e.g., from switch-mode power supplies or wireless transceivers). As shown in Figure 25 of SBOS783, its EMIRR IN+ exceeds 100 dB at 100 MHz - preventing erroneous output shifts in motor control feedback paths or precision measurement systems exposed to industrial EMI sources.
Is TLV171IDBVT pin-compatible with other op amps in the TLVx171 family?
No - TLV171IDBVT (SOT-23-5) has a different pin count and layout than TLV2171 (SOIC-8/VSSOP-8) and TLV4171 (SOIC-14/TSSOP-14). While all share identical electrical specifications, the TLV171IDBVT's 5-pin SOT-23 footprint requires unique PCB layout. Pin compatibility exists only within same-package variants (e.g., TLV171IDBVT and TLV171IDBV), not across channel counts or packages.
