Product details
Overview
TLV4172IPWR from Texas Instruments is a quad-channel, 36-V, rail-to-rail output operational amplifier with EMI-hardened architecture, 10 MHz gain bandwidth, 10 V/μs slew rate, and ±1 μV/°C offset drift-designed for precision signal conditioning in high-voltage industrial sensor interfaces and ADC driver stages.
For engineers reviewing the TLV4172IPWR datasheet, TLV4172IPWR pinout, TLV4172IPWR application, or TLV4172IPWR equivalent, key selection criteria include its 4.5–36 V single-supply operation, 9 nV/√Hz input voltage noise at 1 kHz, 116 dB typical CMRR, low 1.6 mA per amplifier quiescent current, and guaranteed operation from –40°C to +125°C.
Technical Context
The TLV4172IPWR implements 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 filters suppress RF interference without external components.
It delivers stable unity-gain performance into capacitive loads up to 300 pF and maintains 10 MHz bandwidth across full supply (4.5–36 V) and temperature (–40°C to +125°C) ranges-unlike legacy op amps specified only at fixed supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.5 V to 36 V single-supply (±2.25 V to ±18 V); supports direct interfacing with 24-V industrial buses and unregulated DC rails. |
| Gain Bandwidth Product | 10 MHz; enables stable closed-loop gain ≥10 at 1 MHz for anti-aliasing filter design and fast-settling ADC drivers. |
| Slew Rate | 10 V/μs; ensures ≤3.2 μs settling to 0.01% for 10-V steps-critical for multiplexed sensor data acquisition. |
| Input Offset Drift | ±1 μV/°C (typical); limits total offset error to <2.5 μV over –40°C to +125°C, supporting high-accuracy strain gauge amplifiers. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz; preserves SNR in microvolt-level transducer signals (e.g., load cells, thermopiles) without added filtering. |
| CMRR | 116 dB (typical); rejects >100,000:1 common-mode interference in noisy motor drive environments. |
| Quiescent Current | 1.6 mA per amplifier (max 2.3 mA); allows four-channel precision amplification in power-constrained portable instrumentation. |
Pinout & Package
TSSOP-14 package (5.00 mm × 4.40 mm), thin-profile surface-mount, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output; rail-to-rail swing capable of driving 10-kΩ loads within 70 mV of rails at 25°C. |
| 2 | –IN A | Inverting input, channel A; accepts signals 100 mV below V– and up to 2 V below V+ for normal operation. |
| 3 | +IN A | Noninverting input, channel A; matched bias current (±10 pA) minimizes offset in high-impedance sensor bridges. |
| 4 | V+ | Positive supply rail; must be decoupled with ≥0.1 μF ceramic capacitor near pin for EMI immunity. |
| 5 | +IN B | Noninverting input, channel B; electrically isolated from other channels-enables independent gain configurations per channel. |
| 6 | –IN B | Inverting input, channel B; identical input structure to channel A for consistent DC and AC performance. |
| 7 | OUT B | Amplifier B output; fully independent output stage-no crosstalk with channels A, C, or D. |
| 8 | OUT C | Amplifier C output; supports simultaneous multi-channel signal conditioning without shared thermal or supply coupling. |
| 9 | –IN C | Inverting input, channel C; validated for operation with capacitive loads up to 300 pF without instability. |
| 10 | +IN C | Noninverting input, channel C; same ultra-low input bias current as all channels-ideal for photodiode transimpedance stages. |
| 11 | V– | Negative supply rail; referenced to system ground in single-supply mode; requires low-ESR bypassing. |
| 12 | +IN D | Noninverting input, channel D; supports differential input configurations when paired with –IN D on pin 13. |
| 13 | –IN D | Inverting input, channel D; enables true differential-to-single-ended conversion with matched input impedance. |
| 14 | OUT D | Amplifier D output; specified for 75-mA short-circuit current-tolerates momentary output faults without latch-up. |
Key Features
| Feature | Design Value |
|---|---|
| EMI-hardened architecture | Integrated RF filters reject >100-dB interference at 900 MHz and 2.4 GHz-eliminates need for external ferrite beads in wireless-adjacent designs. |
| Rail-to-rail output swing | Drives within 70 mV of rails at 10-kΩ load (25°C), maximizing dynamic range in 3.3-V or 5-V logic-compatible systems. |
| No phase reversal | Input overdrive beyond common-mode range forces output to rail instead of inverting-prevents catastrophic control loop errors in motor feedback paths. |
| Wide supply range | Operates identically from 4.5 V to 36 V-reduces BOM count across 12-V, 24-V, and 36-V industrial platforms. |
| High PSRR (120 dB) | Rejects switching regulator ripple and bus noise-enables clean analog signal paths without dedicated LDOs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4197IPWR | Higher precision (±5 μV max VOS, 0.2 μV/°C drift), lower noise (5.5 nV/√Hz), but higher IQ (1 mA/channel) and narrower supply (4.5–36 V same). | Better for metrology-grade systems requiring <16-bit accuracy; less suitable for battery-powered devices due to higher current. | Choose OPA4197IPWR when offset stability and noise dominate over power; TLV4172IPWR remains optimal for cost-sensitive industrial controls. |
| LM324DR | Lower bandwidth (1.2 MHz), higher offset (3–7 mV), no EMI hardening, wider temp range (–40°C to +125°C same), but lower cost and legacy footprint compatibility. | Acceptable for non-critical DC amplification where EMI immunity and speed are not required. | LM324DR suits legacy redesigns with space constraints; TLV4172IPWR delivers measurable SNR and reliability gains in new designs with RF exposure. |
Compared with OPA4197IPWR and LM324DR, TLV4172IPWR uniquely balances EMI resilience, 10-MHz bandwidth, and 1.6-mA/channel quiescent current-making it the most cost-effective solution for robust, high-fidelity signal chains in automotive and industrial environments.

FAQ
What is the maximum capacitive load the TLV4172IPWR can drive while maintaining stability?
The TLV4172IPWR is specified to remain stable with capacitive loads up to 300 pF in unity-gain configuration. This is verified across temperature (–40°C to +125°C) and supply (4.5–36 V). For loads exceeding 300 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to preserve phase margin. The device's internal compensation eliminates need for external compensation networks in standard applications.
Does the TLV4172IPWR support true rail-to-rail input operation?
The TLV4172IPWR supports input voltages from 100 mV below V– to within 2 V of V+ for full specifications. It can tolerate input signals up to V+ + 0.5 V (absolute max), but performance degrades within 2 V of V+. Unlike true rail-to-rail input op amps, it does not operate linearly at the positive rail-designers must ensure common-mode voltage stays ≥2 V below V+ for guaranteed specs.
How does the EMI-hardening in TLV4172IPWR improve system-level robustness?
The TLV4172IPWR integrates on-die RF filters that attenuate 900-MHz and 2.4-GHz interference by >100 dB, preventing demodulation artifacts in sensitive analog nodes. This eliminates the need for external ferrite beads or RC filters in proximity to wireless modules-reducing PCB area, BOM cost, and tuning effort. Real-world validation shows no visual artifacts in TFT-LCD displays during concurrent Bluetooth/Wi-Fi transmission.
Can TLV4172IPWR operate from a single 5-V supply while maintaining rail-to-rail output?
Yes-TLV4172IPWR operates from 4.5 V to 36 V single supply and delivers rail-to-rail output swing. At 5 V, it drives within 95 mV of each rail (V– and V+) under full temperature range (–40°C to +125°C) with 10-kΩ load. Output voltage swing is load- and temperature-dependent; for 2-kΩ loads, swing degrades to 470–530 mV from rails at extremes.
What is the short-circuit protection behavior of TLV4172IPWR?
TLV4172IPWR provides ±75-mA continuous short-circuit current per amplifier, with thermal shutdown activation above junction temperatures of ~150°C. It does not feature active current limiting-output current is limited by internal transistor safe operating area (SOA). During sustained short-circuit, device enters thermal protection and recovers automatically once cooled. No latch-up occurs under JEDEC-standard ESD or electrical overstress conditions.
