Product details
Overview
TLV3541IDR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for high-speed, low-voltage signal conditioning. It delivers 200MHz unity-gain bandwidth, 150V/μs slew rate, and 7.5nV/√Hz input voltage noise at 1MHz - enabling precise, distortion-free amplification in video line drivers and high-resolution ADC front-ends operating from 2.5V to 5.5V supplies.
For engineers reviewing the TLV3541IDR datasheet, TLV3541IDR pinout, TLV3541IDR application, or TLV3541IDR equivalent, key selection criteria include its 100mV rail-to-rail output swing under load, thermal shutdown protection at 160°C, and verified performance in photodiode transimpedance and fast current-sensing circuits where low input bias (3pA) and high output drive (>100mA) are critical.
Technical Context
The TLV3541IDR employs a complementary CMOS input stage with parallel N- and P-channel differential pairs to achieve rail-to-rail input operation extending 100mV beyond supply rails. Its class AB output stage supports 100mV output swing into 1kΩ loads across –40°C to +125°C.
This amplifier is unity-gain stable and features a 100MHz gain-bandwidth product (GBW), delivering 40MHz 0.1dB gain flatness and <0.02% differential gain error in NTSC video applications. It integrates on-chip thermal shutdown that disables operation above 160°C and resumes at 140°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 200MHz - enables stable operation as voltage follower in high-frequency signal paths without external compensation. |
| Slew rate | 150V/μs - supports clean 2V step response with 3ns rise/fall time and 60ns settling to 0.01%. |
| Input voltage noise | 7.5nV/√Hz at 1MHz - minimizes added noise in low-level sensor and photodiode transimpedance amplifiers. |
| Rail-to-rail I/O | Input common-mode range extends 100mV beyond rails; output swings within 100mV of V+ and V− - maximizes dynamic range in 3.3V or 5V systems. |
| Supply voltage range | 2.5V to 5.5V - supports single-supply operation in battery-powered and low-voltage industrial interfaces. |
| Quiescent current | 5.2mA per channel - balances speed and power efficiency for cost-sensitive, high-bandwidth applications. |
| Output current | >100mA continuous - drives 75Ω video cables, laser diodes, and fast current-sense shunts without external buffers. |
Pinout & Package
TLV3541IDR is available in SOIC-8 (D) and SOT-23-5 (DBV) packages. The D package (3.91mm × 4.90mm) is used for this orderable variant (IDR suffix denotes SOIC-8).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| +IN (Pin 3) | Non-inverting input | High-impedance CMOS node accepting signals from 100mV below V− to 100mV above V+ - enables true single-supply sensor interfacing. |
| –IN (Pin 2) | Inverting input | Differential input terminal; combined with feedback network defines closed-loop gain and stability behavior. |
| OUT (Pin 6) | Amplifier output | Class AB stage capable of sourcing/sinking >100mA while maintaining 100mV rail clearance - suitable for direct 75Ω cable driving. |
| V− (Pin 4) | Negative supply | Reference for lowest supply rail; supports single-supply (ground-referenced) or dual-supply (±1.25V to ±2.75V) operation. |
| V+ (Pin 7) | Positive supply | Highest supply rail; must not exceed 5.5V - absolute maximum rating is 7.5V, beyond which permanent damage occurs. |
| NC (Pins 1, 5, 8) | No internal connection | Unbonded pins; must be left floating or tied to ground for mechanical stability - no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Complementary N/P-channel input pair extends common-mode range beyond supply rails by 100mV - eliminates level-shifting in single-supply ADC driver designs. |
| Thermal shutdown protection | Automatic disable at 160°C junction temperature with recovery at 140°C - prevents latch-up during overload or poor PCB thermal design. |
| Video-optimized performance | 0.02% differential gain / 0.09° differential phase error with 40MHz 0.1dB flatness - meets broadcast-grade NTSC requirements without external peaking networks. |
| Low input bias current | 3pA typical - preserves signal integrity in high-impedance photodiode and piezoelectric sensor interfaces where leakage dominates error budget. |
| Capacitive load drive | Stable with >100pF loads when series output resistor (10–20Ω) is used - enables direct connection to long PCB traces or LCD column drivers without oscillation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA355IDBVR | Higher 250MHz GBW and 350V/μs slew rate; 5.8nV/√Hz noise; SOT-23-5 only. | Better suited for >100MHz transimpedance or RF IF amplification; less optimized for video flatness. | Select OPA355IDBVR when bandwidth and slew rate outweigh video specification compliance and cost sensitivity. |
| LMH6629MA/NOPB | 2.8nV/√Hz noise, 1.5GHz GBW, but 12mA quiescent current and no rail-to-rail output (swing limited to 1.2V from rails). | Preferred for ultra-low-noise preamp stages before ADCs; unsuitable for single-supply video or 3.3V logic interfacing. | Choose LMH6629MA/NOPB only when sub-3nV/√Hz noise is mandatory and supply headroom allows non-rail-to-rail output swing. |
Compared with OPA355IDBVR and LMH6629MA/NOPB, TLV3541IDR provides the optimal balance of 200MHz bandwidth, rail-to-rail I/O, 7.5nV/√Hz noise, and 5.2mA quiescent current - making it uniquely suited for cost-sensitive, low-voltage, high-fidelity video and precision ADC driver applications where thermal robustness and layout simplicity are critical.

FAQ
What is the maximum supply voltage for TLV3541IDR?
The absolute maximum supply voltage (VS = V+ − V−) for TLV3541IDR is 7.5V. However, the recommended operating range is 2.5V to 5.5V. Exceeding 7.5V risks permanent device damage. For reliable long-term operation, TI specifies 5.5V as the upper limit of the functional supply range - TLV3541IDR is fully characterized and guaranteed across this range including thermal shutdown activation at 160°C junction temperature.
Does TLV3541IDR support single-supply operation?
Yes, TLV3541IDR fully supports single-supply operation from 2.5V to 5.5V. Its rail-to-rail input extends 100mV beyond both supply rails, and its output swings within 100mV of V+ and V− under 1kΩ load. This allows direct interfacing with ground-referenced sensors and ADCs without level-shifting circuitry - a key enabler for battery-powered and low-voltage industrial systems using TLV3541IDR.
What is the thermal shutdown behavior of TLV3541IDR?
TLV3541IDR activates thermal shutdown at 160°C junction temperature, disabling output and reducing quiescent current to prevent damage. Normal operation resumes automatically when junction temperature falls below 140°C. This hysteresis prevents cycling near trip point. The shutdown threshold is process-trimmed and specified across –40°C to +125°C ambient - a core reliability feature confirmed in TI's SBOS756A datasheet for TLV3541IDR.
Can TLV3541IDR drive a 75Ω video cable directly?
Yes, TLV3541IDR is explicitly characterized for 75Ω video cable driving in back-terminated configurations. Its >100mA output current, 0.02% differential gain error, and 0.09° differential phase error meet NTSC broadcast standards. Figure 6-3 in the official datasheet shows a validated single-supply video line driver using TLV3541IDR with 604Ω feedback and dual 75Ω terminations - confirming direct interface capability without external buffers.
What package does TLV3541IDR use and what are its dimensions?
TLV3541IDR uses the SOIC-8 (D) package, measuring 3.91mm × 4.90mm (nominal, including pins). This is distinct from the SOT-23-5 variant (TLV3541DBVR). Pin 3 is +IN, Pin 2 is –IN, Pin 6 is OUT, Pin 4 is V−, Pin 7 is V+, and Pins 1/5/8 are NC (no internal connection). The D package supports higher power dissipation than SOT-23 and is preferred for sustained >50mA output applications using TLV3541IDR.
