Product details
Overview
TLV4172IDR from Texas Instruments is a quad-channel, 36-V, rail-to-rail output operational amplifier with 10 MHz gain bandwidth, 10 V/µs slew rate, and low input bias current (10 pA). It operates from ±2.25 V to ±18 V or 4.5 V to 36 V single supply and is specified over –40°C to +125°C for automotive and industrial signal conditioning.
For engineers reviewing the TLV4172IDR datasheet, TLV4172IDR pinout, TLV4172IDR application, or TLV4172IDR equivalent, key selection criteria include its EMI-hardened architecture, ±1 µV/°C offset drift, 9 nV/√Hz input voltage noise at 1 kHz, rail-to-rail output swing within 70 mV of rails (at 25°C, RL = 10 kΩ), and stable operation with up to 300 pF capacitive load.
Technical Context
The TLV4172IDR integrates four independent high-precision op amps in a single SOIC-14 package, each featuring a P-channel input stage enabling rail-to-rail common-mode input down to 100 mV below V– and within 2 V of V+. Its internal phase-reversal protection prevents output inversion when inputs exceed the linear common-mode range.
Designed for cost-sensitive systems requiring microvolt-level signal integrity, it delivers 116 dB typical CMRR and PSRR, 0.0002% THD+N at 1 kHz, and maintains 10 MHz GBP across full supply (4.5 V–36 V) and temperature (–40°C to +125°C) ranges - unlike many op amps specified only at nominal supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supply - supports wide-input industrial and HEV/EV power train monitoring. |
| Gain Bandwidth Product | 10 MHz - enables stable unity-gain buffer and active filter designs up to ~1 MHz without compensation. |
| Slew Rate | 10 V/µs - supports fast settling for 12-bit ADC drivers with ≤3.2 µs to 0.01% for 10-V step. |
| Input Offset Drift | ±1 µV/°C (typical) - ensures <2 mV total offset shift over –40°C to +125°C, critical for precision sensor front-ends. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - low-noise performance suitable for transducer amplification and medical instrumentation. |
| Capacitive Load Drive | Stable with ≤300 pF - allows direct driving of long traces, ADC input capacitance, or LCD column lines without external isolation. |
| Quiescent Current | 1.6 mA per amplifier (max 2.3 mA) - balances speed and power for battery-backed portable instrumentation. |
Pinout & Package
TLV4172IDR is housed in a 14-pin SOIC (D) package measuring 8.65 mm × 3.91 mm, with exposed pad not present and RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives loads ≥2 kΩ without instability. |
| 2 | –IN A | Inverting input, channel A - accepts signals down to V– – 0.1 V, immune to phase reversal. |
| 3 | +IN A | Noninverting input, channel A - high-impedance (10¹³ Ω || 4 pF), low bias current (10 pA). |
| 4 | V+ | Positive supply rail - connects to highest potential supply (up to +36 V or +18 V). |
| 5 | +IN B | Noninverting input, channel B - electrically isolated from channel A; shares no internal nodes. |
| 6 | –IN B | Inverting input, channel B - identical specs to –IN A; supports independent differential configurations. |
| 7 | OUT B | Amplifier B output - fully independent output stage; no crosstalk with OUT A/C/D. |
| 8 | OUT C | Amplifier C output - same drive strength and settling as OUT A/B; usable in multi-channel filters. |
| 9 | –IN C | Inverting input, channel C - supports simultaneous 4-channel signal conditioning without inter-channel coupling. |
| 10 | +IN C | Noninverting input, channel C - matched offset and drift characteristics across all four channels. |
| 11 | V– | Negative supply rail - connects to lowest potential supply (down to –36 V or –18 V); reference for all inputs/outputs. |
| 12 | +IN D | Noninverting input, channel D - enables quad-channel instrumentation amplifier topologies using external resistors. |
| 13 | –IN D | Inverting input, channel D - supports independent feedback networks per channel for mixed-gain configurations. |
| 14 | OUT D | Amplifier D output - full rail-to-rail swing; verified stable with 300 pF load per channel. |
Key Features
| Feature | Design Value |
|---|---|
| EMI-hardened architecture | Immunity to RF interference up to 1 GHz (EMIRR IN+ > 120 dB at 100 MHz), reducing need for external filtering in wireless LAN and touch-screen environments. |
| Rail-to-rail output swing | Within 70 mV of rails at 25°C (RL = 10 kΩ), preserving dynamic range in low-voltage data acquisition systems. |
| No phase reversal | Input overdrive beyond (V+) – 2 V clamps output to rail instead of inverting - eliminates latch-up risk in open-loop comparator modes. |
| Low input bias current | 10 pA maximum at 25°C - enables high-impedance sensor interfaces (e.g., piezoelectric, pH electrodes) without significant error. |
| Wide supply flexibility | Specified from 4.5 V to 36 V - simplifies design reuse across 5 V, 12 V, 24 V, and 32 V industrial platforms without requalification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4172IPW | Same 36-V supply, 10 MHz GBP, but lower input bias current (±0.3 pA) and higher quiescent current (1.8 mA per amp). | Better for ultra-high-impedance pH or photodiode sensors; less suitable for battery-powered portable devices. | Choose OPA4172IPW when sub-picoampere bias current outweighs power budget constraints. |
| LM324DR | Lower supply range (3–32 V), slower (1.2 MHz GBP), higher offset drift (7 µV/°C), no EMI hardening or phase-reversal protection. | Acceptable for non-critical industrial controls where cost dominates performance requirements. | Choose LM324DR only for legacy cost-sensitive designs where 10 MHz bandwidth and ±1 µV/°C drift are not required. |
Compared with OPA4172IPW, TLV4172IDR trades 0.7 pA input bias current for 0.2 mA lower quiescent current per amplifier and broader temperature qualification (–40°C to +125°C vs –40°C to +125°C, same range but tighter drift spec). Against LM324DR, TLV4172IDR provides 8.3× higher bandwidth, 7× lower drift, and robust EMI immunity - justifying upgrade in precision or automotive applications.

FAQ
What is the operating temperature range for TLV4172IDR?
The TLV4172IDR is specified to operate from –40°C to +125°C. This extended industrial temperature range is validated across all key parameters including offset voltage drift (±1 µV/°C), gain bandwidth (10 MHz), and output swing. It enables use in engine control units, motor drives, and outdoor instrumentation where ambient temperatures exceed standard commercial limits. The datasheet guarantees performance across this full range without derating.
Does TLV4172IDR support single-supply operation?
Yes, TLV4172IDR supports true single-supply operation from 4.5 V to 36 V. Its input common-mode range extends 100 mV below the negative rail (V–) and within 2 V of the positive rail (V+), while the rail-to-rail output swings within 70 mV of both rails at 25°C. This allows direct interfacing with unipolar sensors and ADCs without level-shifting circuitry - a key advantage over older op amps requiring dual supplies for full-range signal handling.
What is the maximum capacitive load TLV4172IDR can drive stably?
TLV4172IDR is stable with capacitive loads up to 300 pF, as confirmed in the datasheet's Typical Characteristics (Figures 13–14) and Electrical Characteristics table. This capability eliminates the need for external series resistance in applications like driving ADC input capacitance, long PCB traces, or LCD column lines. Stability is maintained across all supply voltages (4.5 V–36 V) and temperatures (–40°C to +125°C), making it suitable for high-speed data acquisition systems.
How does TLV4172IDR handle input overvoltage conditions?
TLV4172IDR features internal phase-reversal protection that prevents output inversion when inputs exceed the linear common-mode range. Instead of reversing polarity, the output clamps to the appropriate rail. This behavior is documented in Figure 15 ("No Phase Reversal") and applies across the full –40°C to +125°C range. It enhances reliability in comparator-like configurations or transient-overvoltage scenarios without requiring external clamping diodes.
Is TLV4172IDR pin-compatible with other quad op amps in SOIC-14 packages?
No, TLV4172IDR has a unique pinout optimized for quad-channel independence: pins 1/7/8/14 are outputs, pins 2/3/5/6/9/10/12/13 are inputs, and pins 4/V+ and 11/V– are shared supplies. It is not pin-compatible with legacy SOIC-14 quad op amps like LM324 or TL074, which use different input/output assignments. PCB layout must follow the TLV4172-specific pin mapping shown in Section 6 of the SBOS784C datasheet.
