Product details
Overview
TLV171IDBVR 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 TLV171IDBVR datasheet, TLV171IDBVR pinout, TLV171IDBVR application, or TLV171IDBVR equivalent, key selection criteria include its EMI-hardened RFI-filtered inputs, unity-gain stability with 200-pF capacitive loads, rail-to-rail output swing within 90–160 mV of rails, and operation across –40°C to +125°C without phase reversal on overdriven inputs.
Technical Context
The TLV171IDBVR employs a P-channel input stage enabling rail-to-rail common-mode input range (V− − 0.1 V to V+ − 2 V) and phase-reversal protection. Its internal ESD structure includes back-to-back input diodes and supply-rail clamping with ±4000-V HBM rating.
It achieves unity-gain stability via internal compensation while maintaining 1.5 V/µs slew rate and 6 µs 0.1% settling time (10-V step). The amplifier's low 10 pA bias current and 105 dB typical CMRR support high-impedance sensor interfacing and precision active filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 2.7 V to 36 V single supply (±1.35 V to ±18 V) - supports wide-input industrial power rails and battery voltage decay. |
| Gain Bandwidth | 3 MHz - enables stable closed-loop operation up to ~200 kHz at G = 15 without peaking. |
| Input Voltage Noise | 16 nV/√Hz at 1 kHz - suitable for low-level transducer amplification without significant noise contribution. |
| Offset Drift | ±1 μV/°C (typical) - ensures < ±12 μV total drift over –40°C to +125°C, critical for uncalibrated temperature-stable designs. |
| Quiescent Current | 525 µA per amplifier - allows dual-stage signal conditioning in 10-year battery-powered instruments. |
| Capacitive Load Drive | Stable with ≤200 pF - eliminates need for external isolation resistors in standard PCB trace and scope probe loading. |
| Common-Mode Range | V− − 0.1 V to V+ − 2 V - permits direct sensing of signals referenced to negative rail in single-supply systems. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads, RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Rail-to-rail output capable of sourcing/sinking ≥25 mA; swings within 90 mV of V− and 160 mV of V+ at ±18 V. |
| 2 - V− | Negative supply | Lowest potential rail; input common-mode extends 100 mV below this pin - enables true single-supply ground-referenced inputs. |
| 3 - +IN | Noninverting input | High-impedance node (10¹² Ω || 3 pF); 10 pA bias current minimizes error in high-Z sensor interfaces. |
| 4 - −IN | Inverting input | Differential pair input; matched to +IN for < ±2.7 mV offset; EMI-hardened with integrated RFI filtering. |
| 5 - V+ | Positive supply | Highest potential rail; supports up to 36 V; internal protection limits absolute max to ±20 V across V+–V−. |
Key Features
| Feature | Design Value |
|---|---|
| EMI-hardened inputs | Integrated RFI filters suppress >100 MHz RF interference - prevents erroneous output shifts in noisy industrial environments. |
| No phase reversal | Input overdrive beyond common-mode range forces output to rail instead of inverting - avoids catastrophic control loop failure in motor drives. |
| Rail-to-rail output | Delivers full dynamic range into 10-kΩ loads - maximizes ADC utilization in 12-bit battery-powered data loggers. |
| Wide temperature range | Specified from –40°C to +125°C - qualified for under-hood automotive power modules and industrial inverters. |
| Low power precision | 525 µA IQ with 105 dB CMRR and 3 MHz GBW - achieves performance previously requiring >2× current in legacy op amps. |
Applications
| AC-DC Converters | TFT-LCD Drive Circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA192IDBVR | Higher precision: 5 µV max offset, 0.2 µV/°C drift, but 1 mA IQ and $0.35 higher unit cost. | Better for calibrated lab equipment; less suitable for 10-year battery life targets. | Select TLV171IDBVR when cost and power dominate; OPA192IDBVR only if sub-10 µV offset is mandatory. |
| LM321IDBVR | Narrower supply: 3–32 V; lower GBW (1 MHz); no phase-reversal protection; 700 µA IQ. | Acceptable for non-critical consumer power supplies but fails in automotive or industrial overvoltage conditions. | TLV171IDBVR preferred where input overdrive immunity or extended temperature operation is required. |
Compared with OPA192IDBVR and LM321IDBVR, TLV171IDBVR uniquely balances 36-V operation, EMI hardening, phase-reversal immunity, and sub-600-µA quiescent current - making it the optimal choice for uncalibrated, long-life, noise-prone industrial signal chains.

FAQ
What is the maximum capacitive load the TLV171IDBVR can drive without oscillation?
The TLV171IDBVR is unity-gain stable with capacitive loads up to 200 pF, as verified in TI's SBOS783 datasheet Figure 14–15. This specification holds for standard PCB layouts with 10-kΩ load; exceeding 200 pF requires an isolation resistor (e.g., 50 Ω) in series with the output. No external compensation is needed within this limit, simplifying layout for space-constrained applications like TFT-LCD column drivers.
Does the TLV171IDBVR support true rail-to-rail input operation?
The TLV171IDBVR supports rail-to-rail input common-mode voltage from V− − 0.1 V to V+ − 2 V for normal operation, per Section 7.4.1 of the datasheet. It can accept inputs up to V+ + 0.1 V, but performance (CMRR, PSRR) degrades within 2 V of V+. This architecture enables direct interface with ground-referenced sensors in single-supply systems without level-shifting circuitry - a key advantage over conventional op amps.
What is the guaranteed operating temperature range for TLV171IDBVR?
The TLV171IDBVR is fully specified and production-tested from –40°C to +125°C, with electrical characteristics guaranteed across this range (Section 6.3). Absolute maximum ratings extend to –55°C to +150°C, but parametric performance is not assured outside the –40°C to +125°C range. This makes TLV171IDBVR suitable for under-hood automotive modules and industrial inverters where ambient temperatures exceed 85°C.
How does the EMI-hardening feature of TLV171IDBVR improve system reliability?
The TLV171IDBVR integrates RFI-filtered inputs that attenuate high-frequency electromagnetic interference (>100 MHz), preventing false output transitions in noisy environments like motor drives or switch-mode power supplies. This is confirmed by EMI rejection ratio (EMIRR) plots in Figure 25 of SBOS783, showing >80 dB suppression at 1 GHz. Unlike unhardened op amps, TLV171IDBVR avoids erratic behavior without requiring external ferrite beads or RC filters.
Can TLV171IDBVR be used in dual-supply configurations?
Yes, TLV171IDBVR supports dual-supply operation from ±1.35 V to ±18 V, as explicitly stated in the Features and Recommended Operating Conditions sections of SBOS783. Its input common-mode range extends 100 mV beyond the negative rail, allowing use with split supplies in traditional op amp topologies like inverting amplifiers and active filters - while retaining all low-noise, low-drift, and EMI-hardening benefits.
