Product details
Overview
TLV172IDBVT from Texas Instruments is a single-channel, 36-V, rail-to-rail output operational amplifier with EMI-hardened design, 10 MHz gain bandwidth, 10 V/μs slew rate, and low input bias current of 10 pA - used in precision ADC buffering, active filtering, and portable instrumentation requiring stable microvolt-level signal amplification.
For engineers reviewing the TLV172IDBVT datasheet, TLV172IDBVT pinout, TLV172IDBVT application, or TLV172IDBVT equivalent, key selection criteria include its ±1 μV/°C offset drift, 9 nV/√Hz input voltage noise at 1 kHz, 116 dB typical CMRR, operation from 4.5 V to 36 V (±2.25 V to ±18 V), and guaranteed performance over –40°C to +125°C.
Technical Context
The TLV172IDBVT employs a P-channel input stage enabling rail-to-rail common-mode input down to 100 mV below V– and within 2 V of V+, with no phase reversal beyond the linear range. Its internal EMI-hardening circuitry suppresses high-frequency interference without external filtering.
It delivers 10 MHz unity-gain bandwidth and 10 V/μs slew rate while maintaining only 1.6 mA quiescent current per amplifier across temperature, and remains stable driving capacitive loads up to 300 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 36 V single-supply (±2.25 V to ±18 V dual); supports wide industrial and automotive power rails. |
| Gain Bandwidth Product | 10 MHz; enables stable unity-gain buffer or closed-loop gain ≥2 configurations up to ~5 MHz. |
| Slew Rate | 10 V/μs; supports clean 10-V step response in ≤2 µs (0.1% settling) for fast-sampling systems. |
| Input Offset Drift | ±1 μV/°C (typical); ensures <2 µV total drift over –40°C to +125°C, critical for DC-coupled sensor interfaces. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz; low enough for amplifying µV-level transducer outputs without dominating system noise floor. |
| CMRR | 116 dB (typical); rejects common-mode interference in noisy environments like motor drives or power supplies. |
| Quiescent Current | 1.6 mA per amplifier (max 2.3 mA over temp); balances speed and power efficiency in battery-powered instruments. |
Pinout & Package
TLV172IDBVT is packaged in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Rail-to-rail output capable of sourcing/sinking ±75 mA; swings within 70 mV of rails at 10 kΩ load. |
| 2 - V– | Negative Supply | Reference for lowest supply rail; input common-mode extends 100 mV below this pin. |
| 3 - +IN | Noninverting Input | High-impedance (10¹³ Ω || 4 pF) P-channel input; accepts signals down to V– – 0.1 V. |
| 4 - –IN | Inverting Input | Matches +IN in impedance and voltage range; enables precision differential or inverting configurations. |
| 5 - V+ | Positive Supply | Highest supply rail; input operates within 2 V of this pin under normal conditions. |
Key Features
| Feature | Design Value |
|---|---|
| EMI-Hardened Architecture | Integrated on-die filtering reduces susceptibility to GSM, Wi-Fi, and switching regulator noise without external ferrites. |
| Rail-to-Rail Output Swing | Drives loads to within 70 mV of either supply rail at 10 kΩ, maximizing dynamic range in single-supply systems. |
| No Phase Reversal | Input overdrive beyond common-mode range clamps output to appropriate rail instead of inverting polarity. |
| Low Input Bias Current | 10 pA (typ) enables high-impedance sensor interfacing (e.g., pH electrodes, piezoresistive bridges) without significant error. |
| Capacitive Load Drive | Stable with up to 300 pF directly on output; eliminates need for isolation resistors in LCD driver or cable-drive applications. |
Applications

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 VOS vs TLV172IDBVT's 1.7 mV typ; 5.5 nV/√Hz noise; 20 V/μs slew rate; 1 mA IQ. | Better suited for 20-bit+ precision data acquisition; less ideal for cost-sensitive, high-speed buffering. | Select OPA192IDBVT when sub-10 μV offset and lower noise dominate over cost and power. |
| LMV721IDBVR | Lower voltage: 2.7–5.5 V supply; 10 MHz GBW; 5.5 V/μs slew; 1.25 mA IQ; 12 nV/√Hz noise; not specified beyond 125°C. | Targeted at 3.3-V portable systems only; lacks extended temperature and high-voltage robustness. | Select LMV721IDBVR only for low-voltage, commercial-temp consumer designs where 36-V capability is unnecessary. |
Compared with OPA192IDBVT and LMV721IDBVR, TLV172IDBVT uniquely balances 36-V operation, EMI hardening, 10 MHz bandwidth, and 1.6 mA IQ across –40°C to +125°C - making it optimal for industrial, automotive, and portable instrumentation where supply flexibility and noise immunity are non-negotiable.

FAQ
What is the maximum capacitive load the TLV172IDBVT can drive without oscillation?
The TLV172IDBVT is specified stable with capacitive loads up to 300 pF when configured as a unity-gain buffer. This allows direct connection to LCD column lines, long cables, or ADC input capacitance without requiring isolation resistors or external compensation networks - verified across –40°C to +125°C and full supply range.
Does TLV172IDBVT support true rail-to-rail input operation?
The TLV172IDBVT supports input common-mode voltage from 100 mV below V– to within 2 V of V+ under normal operation. It can tolerate input signals up to V+ + 0.5 V (absolute max), but performance degrades within 2 V of V+. So while not full rail-to-rail input, its extended range enables single-supply operation with ground-referenced sensors and high-side sensing.
What is the typical input offset voltage drift of TLV172IDBVT over temperature?
The TLV172IDBVT has a typical input offset voltage drift of ±1 μV/°C over –40°C to +125°C. This low drift ensures minimal baseline shift in precision DC-coupled applications such as strain gauge amplifiers or thermocouple signal chains, contributing to <2 µV total drift across the full industrial temperature range.
How does the EMI-hardening feature of TLV172IDBVT improve system reliability?
The EMI-hardening in TLV172IDBVT uses on-die filtering and layout techniques to suppress RF interference (e.g., from GSM, Bluetooth, or switch-mode power supplies) before it modulates the input stage. This prevents erroneous output behavior in noisy environments - such as automotive infotainment displays or factory-floor instrumentation - without requiring external shielding or ferrite beads.
Can TLV172IDBVT operate from a single 5-V supply?
Yes, TLV172IDBVT is fully specified from 4.5 V to 36 V single-supply operation. At 5 V, it maintains 10 MHz GBW, 10 V/μs slew rate, rail-to-rail output swing, and 1.6 mA quiescent current - making it suitable for 5-V microcontroller-based systems, USB-powered test gear, and legacy industrial controllers requiring upgrade paths to higher supply voltages.
