Product details
Overview
TLV9361IDCKR 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 serves precision signal conditioning in motor drive power stages and programmable logic controllers.
For engineers reviewing the TLV9361IDCKR datasheet, TLV9361IDCKR pinout, TLV9361IDCKR application, or TLV9361IDCKR equivalent, this page provides verified specifications, SC70-5 package details, thermal performance data, EMI rejection metrics, and validated alternative op-amps for high-voltage industrial analog design.
Technical Context
The TLV9361IDCKR employs a P-channel input stage enabling rail-to-rail common-mode input range down to V– and up to (V+) – 2 V, with robust 110 dB CMRR at 40 V supply. Its internal slew boost circuitry sustains 25 V/µs across full temperature range (–40°C to 125°C) while maintaining unity-gain stability into 20 pF capacitive loads.
EMI rejection is implemented via integrated RF filtering on IN+ and IN– pins, delivering 70.0 dB EMIRR at 2.4 GHz and 91.0 dB at 5 GHz-critical for operation near Wi-Fi, Bluetooth, and cellular bands in dense industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10.6 MHz - supports stable closed-loop gain ≥10 up to ~1 MHz; enables fast settling in sensor front-ends. |
| Slew rate | 25 V/µs - drives 10-V step signals in ≤0.44 µs (0.01% settling), suitable for pulse-width modulation feedback loops. |
| Input offset voltage | ±0.4 mV (max) - ensures <1 LSB error in 12-bit ADC interfaces with 4.096-V reference. |
| Supply voltage range | 4.5 V to 40 V - powers directly from industrial 24-V rails or wide-input DC-DC outputs without regulation. |
| Output current | ±60 mA - drives low-impedance loads (e.g., 66 Ω termination) without external buffers in analog output modules. |
| EMIRR at 2.4 GHz | 70.0 dB - suppresses 2.4-GHz ISM band interference by >3,000×, reducing noise coupling in motor control PCBs. |
| Quiescent current | 2.6 mA per amplifier - enables multi-channel analog I/O with <13 mW dissipation at 5 V, easing thermal design. |
Pinout & Package
TLV9361IDCKR is housed in a 5-pin SC70 package (2.00 mm × 1.25 mm), optimized for space-constrained industrial modules and PLC I/O cards. Thermal resistance RθJA is 198.1°C/W, requiring minimal copper area for operation at full 125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Noninverting input | Accepts common-mode voltages from V– to (V+) – 2 V; integrated EMI filter improves noise immunity. |
| 2 - V– | Negative supply | Reference for dual-supply (±2.25 V to ±20 V) or ground in single-supply (4.5 V to 40 V) configurations. |
| 3 - IN– | Inverting input | Differential input node with ±10 pA bias current; matched to IN+ for low offset drift in precision integrators. |
| 4 - OUT | Amplifier output | Rail-to-rail swing: within 60 mV of rails at 10 kΩ load; delivers ±60 mA into resistive loads. |
| 5 - V+ | Positive supply | Highest potential supply pin; supports up to 40 V; internal protection limits absolute max to 42 V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 60 mV of V+ and V– at 10 kΩ load, preserving dynamic range in 24-V industrial sensors. |
| EMI rejection filtering | 70.0 dB rejection at 2.4 GHz enables reliable operation on PCBs with co-located Wi-Fi/BT modules. |
| High slew rate + GBW | 25 V/µs slew into 10.6-MHz bandwidth allows accurate amplification of 1-MHz sine waves with <0.1% THD+N. |
| Low offset drift | ±1.25 µV/°C ensures <1.25 µV total drift over 100°C span-critical for uncalibrated temperature transducer circuits. |
| Thermal shutdown | Activates at 170°C junction temperature, protecting against sustained overload in motor current-sense paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA192IDBVR | Lower offset (±5 µV), higher IQ (1 mA), 10-MHz GBW, same SC70-5 package | Better DC precision but higher cost; less suitable for high-current drive (±25 mA only) | Select when ultra-low offset dominates over output drive and cost sensitivity. |
| LM7321MAX/NOPB | Wider temp range (–40°C to 150°C), lower slew (20 V/µs), 20-MHz GBW, SOIC-8 only | Higher temperature rating but no SC70 option; requires PCB redesign for footprint | Choose for extended-temperature automotive or aerospace use where SC70 is not required. |
Compared with OPA192IDBVR and LM7321MAX/NOPB, TLV9361IDCKR uniquely balances 40-V operation, ±60 mA drive, 25 V/µs slew, and SC70 packaging-making it optimal for space-constrained, high-voltage industrial I/O where cost and robustness are primary selection criteria.

FAQ
What is the maximum supply voltage for TLV9361IDCKR?
The absolute maximum supply voltage for TLV9361IDCKR is 42 V, with recommended operation from 4.5 V to 40 V. Exceeding 42 V risks permanent damage. At 40 V supply, the device maintains full specification compliance including 110 dB CMRR and 25 V/µs slew rate across –40°C to 125°C.
Does TLV9361IDCKR support rail-to-rail input?
TLV9361IDCKR does not support rail-to-rail input; its common-mode input range extends from V– to (V+) – 2 V. This allows full utilization of negative rail in dual-supply configurations and accommodates 0–22 V input in 24-V single-supply systems, matching typical industrial sensor output spans.
What is the thermal shutdown threshold of TLV9361IDCKR?
TLV9361IDCKR activates thermal shutdown at approximately 170°C junction temperature. The device disables output drive until junction temperature falls below the hysteresis threshold (~155°C), protecting against sustained overload in motor current-sense or high-power buffer applications.
Can TLV9361IDCKR drive capacitive loads without oscillation?
TLV9361IDCKR remains stable into 20 pF capacitive loads at unity gain, with 64° phase margin. For loads >20 pF, a series isolation resistor (RISO = 50 Ω) restores stability-verified in Figure 6-28 of the datasheet-enabling direct connection to long cables or ADC input filters.
Is TLV9361IDCKR pin-compatible with other SC70-5 op-amps?
TLV9361IDCKR uses standard SC70-5 pinout (IN+, V–, IN–, OUT, V+), matching industry conventions. However, electrical differences-including 40-V rating, ±60 mA drive, and EMI filtering-require validation in target circuits; it is not a drop-in replacement for legacy 5.5-V or 12-V SC70 op-amps.
