Product details
Overview
TLV172IDBVR from Texas Instruments is a single-channel, 36-V, rail-to-rail output operational amplifier with EMI hardening, 10 MHz gain bandwidth, 10 V/µs slew rate, and 1.6 mA quiescent current per amplifier-designed for precision signal conditioning in portable instrumentation and ADC buffering applications.
For engineers reviewing the TLV172IDBVR datasheet, TLV172IDBVR pinout, TLV172IDBVR application, or TLV172IDBVR equivalent, key selection considerations include its ±1 µV/°C offset drift, 9 nV/√Hz input voltage noise at 1 kHz, rail-to-rail output swing within 70 mV of supply rails (at 25°C), operation from 4.5 V to 36 V single supply, and stable performance with up to 300 pF capacitive load.
Technical Context
The TLV172IDBVR uses a bipolar input stage with PCH/NCH complementary input transistors, enabling rail-to-rail input operation down to 100 mV below V– and within 2 V of V+, while avoiding phase reversal beyond common-mode limits. Its second-stage gain and class-AB output stage deliver 10 MHz unity-gain bandwidth and 10 V/µs slew rate with low distortion (0.0002% THD+N at 1 kHz).
EMI-hardened design includes internal filtering on input pins and optimized layout to suppress RF rectification. The device maintains 116 dB typical CMRR and >100 dB PSRR across frequency, supporting high-accuracy amplification of microvolt-level signals in noisy automotive and medical environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 36 V single supply - supports wide-input industrial and automotive power rails without level-shifting. |
| Gain Bandwidth Product | 10 MHz - enables stable closed-loop operation up to 100 kHz at G = 100 without compensation. |
| Slew Rate | 10 V/µs - ensures <3.2 µs settling to 0.01% for 10-V steps, suitable for fast data acquisition buffers. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - preserves SNR in low-amplitude sensor signal chains (e.g., strain gauges, thermopiles). |
| Offset Drift | ±1 µV/°C - guarantees <12 µV total drift over –40°C to +125°C, critical for uncalibrated embedded systems. |
| Capacitive Load Drive | Stable with ≤300 pF - allows direct driving of ADC input capacitance or long PCB traces without external isolation. |
| Quiescent Current | 1.6 mA per amplifier - enables battery-powered operation with multi-second runtime in portable instrumentation. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads, JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +IN | Noninverting input - accepts signals down to V– – 0.1 V; high-impedance (10¹³ Ω) for minimal loading of high-Z sources. |
| 2 | V– | Negative supply terminal - must be connected to lowest system potential; supports true single-supply operation with ground-referenced inputs. |
| 3 | –IN | Inverting input - matched to +IN for <2 µV input offset; differential input impedance 100 MΩ || 4 pF. |
| 4 | OUT | Amplifier output - rail-to-rail swing (70 mV from rails at 25°C, 95 mV at 125°C) into 10 kΩ loads. |
| 5 | V+ | Positive supply terminal - accepts up to 36 V; internal ESD protection clamps transients to safe levels. |
Key Features
| Feature | Design Value |
|---|---|
| EMI Hardening | Integrated RF filtering and layout optimization suppresses rectified interference from cellular/Wi-Fi bands, preventing DC offset shifts in sensitive analog front-ends. |
| No Phase Reversal | Input common-mode range extends 100 mV beyond V+; output saturates cleanly instead of inverting when inputs exceed linear range. |
| Rail-to-Rail Output | Drives within 70 mV of V+ and V– at 25°C - maximizes dynamic range in 3.3 V or 5 V ADC buffer stages. |
| Low Input Bias Current | ±10 pA at 25°C - avoids significant voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode TIA feedback networks). |
| High PSRR/CMRR | 120 dB PSRR and 116 dB CMRR - rejects supply ripple and common-mode noise in HEV powertrain monitoring and medical EEG amplifiers. |

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; 13 MHz GBW; 2.2 mA IQ. | Better for calibrated lab equipment; less suitable for cost-sensitive portable designs. | Choose OPA192IDBVR when offset stability dominates over power and BOM cost. |
| LMV721IDBVR | Lower voltage: 2.7–5.5 V only; 10 MHz GBW; 1.25 mA IQ; no EMI hardening. | Limited to 3.3 V systems; unsuitable for automotive or industrial 12–24 V rails. | Choose LMV721IDBVR only for ultra-low-voltage, non-EMI-critical consumer electronics. |
Compared with OPA192IDBVR and LMV721IDBVR, TLV172IDBVR uniquely balances 36-V operation, EMI resilience, and sub-2 mA quiescent current-making it optimal for uncalibrated, wide-supply industrial sensors and portable test gear where robustness and supply flexibility outweigh ultra-low offset requirements.

FAQ
What is the maximum capacitive load the TLV172IDBVR can drive without instability?
The TLV172IDBVR is specified stable with capacitive loads up to 300 pF under all operating conditions. This capability eliminates the need for external isolation resistors when driving SAR ADC inputs or long PCB traces, simplifying layout and preserving signal integrity in data acquisition systems using TLV172IDBVR.
Does the TLV172IDBVR support true single-supply operation with input signals referenced to ground?
Yes. The TLV172IDBVR features an input common-mode range extending 100 mV below V–, allowing ground-referenced inputs when V– = 0 V. Its rail-to-rail output swings within 70 mV of both supply rails at 25°C, making TLV172IDBVR ideal for single-supply sensor interfaces and 3.3 V/5 V microcontroller-based systems.
How does the EMI hardening in TLV172IDBVR improve system-level reliability?
TLV172IDBVR incorporates on-die RF filters and layout techniques that suppress rectification of 800 MHz–2.5 GHz signals (e.g., GSM, Wi-Fi), preventing induced DC offset errors in precision analog paths. This hardening ensures consistent performance in wireless-enabled medical devices and automotive infotainment systems where TLV172IDBVR is deployed near RF transceivers.
What is the temperature range over which TLV172IDBVR maintains full specifications?
The TLV172IDBVR is fully specified from –40°C to +125°C ambient temperature. Key parameters-including offset drift (±1 µV/°C), quiescent current (1.6–2.3 mA), and CMRR (≥94 dB)-are guaranteed across this range, enabling use in under-hood automotive modules and industrial motor drives where TLV172IDBVR operates without derating.
Can TLV172IDBVR replace older op amps like TLC2272 in existing designs?
TLV172IDBVR offers superior specs versus TLC2272: wider supply (4.5–36 V vs 4.4–16 V), lower noise (9 nV/√Hz vs 12 nV/√Hz), and EMI hardening. Pin compatibility depends on package-TLV172IDBVR in SOT-23-5 matches TLC2272IDBVR pinout, but designers must verify layout for improved thermal performance and noise immunity in the final TLV172IDBVR implementation.
