Product details
Overview
TLV9361IDBVR from Texas Instruments is a single-channel, rail-to-rail output operational amplifier optimized for cost-sensitive, high-voltage systems. It delivers 10.6-MHz gain-bandwidth, 25 V/µs slew rate, ±400 µV max input offset voltage, ±1.25 µV/°C offset drift, and operates from 4.5 V to 40 V supply. It is used in motor drive servo control modules where precision, speed, and wide supply range are critical.
For engineers reviewing the TLV9361IDBVR datasheet, TLV9361IDBVR pinout, TLV9361IDBVR application, or TLV9361IDBVR equivalent, key selection criteria include its 40-V operation capability, low 2.6 mA quiescent current per amplifier, robust EMIRR performance at 2.4 GHz (70 dB), and SOT-23-5 package compatibility with space-constrained industrial signal conditioning designs.
Technical Context
The TLV9361IDBVR employs a P-channel input stage enabling rail-to-rail common-mode input range down to V– and supports differential input voltages up to VS + 0.2 V. Its internal slew boost circuitry enables 25 V/µs slew rate while maintaining unity-gain stability with 20 pF capacitive load.
It features integrated EMI filtering targeting 400 MHz–5 GHz interference sources-critical for noisy industrial environments-and thermal shutdown protection activating above 170°C junction temperature to prevent permanent damage during sustained overload conditions.
Key Specifications

|---|---|
| Gain-bandwidth product | 10.6 MHz - supports stable closed-loop operation up to ~1 MHz at G = 10 without phase margin degradation |
| Slew rate | 25 V/µs - enables <0.65 µs settling to 0.1% for 10-V step, suitable for fast feedback loops in servo drives |
| Input offset voltage | ±400 µV (max) - ensures ≤4 mV error in 10-V full-scale measurement at room temperature |
| Offset voltage drift | ±1.25 µV/°C - contributes <150 µV error over –40°C to 125°C ambient, minimizing calibration burden |
| Supply voltage range | 4.5 V to 40 V - supports direct connection to 24-V industrial rails and 36-V battery systems without regulation |
| Output current | ±60 mA - drives 667 Ω loads at ±20 V supply while maintaining rail-to-rail swing within 100 mV |
| EMI rejection | 70 dB at 2.4 GHz - suppresses Wi-Fi/Bluetooth interference in densely packed PLC and motor control PCBs |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Within 100 mV of rails at 10-kΩ load and 40-V supply - preserves dynamic range in high-side sensing |

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 offset), lower noise (5.5 nV/√Hz), but 1 mA higher IQ and 2× cost | Better suited for high-accuracy DAQ, less ideal for cost-driven motor control BOMs | Select when offset drift <0.5 µV/°C and THD+N <–120 dB are mandatory; avoid if 2.6 mA IQ is critical |
| LM7321MAX/NOPB | Wider temp range (–40°C to 150°C), same 40-V rating, but only 22 V/µs slew rate and no EMIRR spec | Used in automotive under-hood sensors; lacks EMI hardening for industrial RF-dense environments | Choose for extended temperature operation where EMI immunity is secondary; verify 22 V/µs meets loop bandwidth needs |
Compared with OPA192IDBVR and LM7321MAX/NOPB, TLV9361IDBVR uniquely balances 40-V operation, 25 V/µs slew rate, and documented 70 dB EMIRR at 2.4 GHz-making it optimal for cost-sensitive industrial drives requiring both speed and noise resilience.

FAQ
What is the maximum supply voltage rating for TLV9361IDBVR?
The TLV9361IDBVR supports an absolute maximum supply voltage of 42 V (V+ to V–), with recommended operation from 4.5 V to 40 V. This 40-V rating enables direct interface with 24-V and 36-V industrial power rails without external regulation, reducing system complexity in motor drive and PLC applications.
Does TLV9361IDBVR support rail-to-rail input operation?
TLV9361IDBVR supports rail-to-rail *output* swing but has a limited common-mode input range of (V–) to (V+) – 2 V. Its P-channel input stage allows the input to reach V–, but does not extend fully to V+. For true rail-to-rail input, consider TI's TLV9061 or OPA333 families instead.
What is the thermal shutdown threshold for TLV9361IDBVR?
The TLV9361IDBVR activates thermal shutdown when its internal junction temperature exceeds 170°C. This protection disables the output stage until temperature falls below the hysteresis threshold (~155°C), preventing permanent damage during sustained overload or poor PCB heat dissipation in confined SOT-23 layouts.
Can TLV9361IDBVR drive a 10-kΩ load at 40-V supply while maintaining rail-to-rail output?
Yes. At 40-V supply and 10-kΩ load, TLV9361IDBVR delivers output swing within 60–100 mV of each rail (positive and negative headroom), meeting rail-to-rail specification. Performance degrades to ~250 mV headroom at 2-kΩ load, confirming its ±60 mA output drive capability per the datasheet.
Is TLV9361IDBVR pin-compatible with other SOT-23-5 op amps like the TLV2461 or OPA344?
No. TLV9361IDBVR uses standard SOT-23-5 pinout (OUT, V–, IN+, IN–, V+), but functional compatibility requires verification of supply range, input topology, and output stage behavior. While pinout matches many single op amps, its 40-V rating, P-channel input, and EMI filtering differentiate it from legacy 5.5-V or 12-V devices like TLV2461 or OPA344.
