Product details
Overview
TLV3544IDR from Texas Instruments is a quad-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, 7.5nV/√Hz input voltage noise, ±100mA output drive, and operates from 2.5V to 5.5V supply - enabling use in ADC driver, video line driving, and photodiode transimpedance applications.
For engineers reviewing the TLV3544IDR datasheet, TLV3544IDR pinout, TLV3544IDR application, or TLV3544IDR equivalent, key selection criteria include its quad-channel SOIC-14/TSSOP-14 package, guaranteed 0.1dB gain flatness to 40MHz, thermal shutdown at 160°C, and verified performance in single-supply video and fast current-sensing circuits.
Technical Context
The TLV3544IDR uses a complementary CMOS input stage enabling rail-to-rail input common-mode range extending 100mV beyond both supply rails. Its class AB output stage achieves 100mV rail-to-rail swing into 1kΩ loads across –40°C to +125°C.
It is unity-gain stable with 100MHz gain-bandwidth product (G = +10), supports 0.01% settling in 60ns, and features integrated thermal shutdown that disables operation above 160°C junction temperature and re-enables at 140°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 200MHz - enables stable closed-loop operation up to 200MHz in G = +1 configuration |
| Slew rate | 150V/μs - supports clean 2V step response with <11ns rise/fall time and minimal distortion |
| Input voltage noise | 7.5nV/√Hz at 1MHz - critical for low-noise transimpedance and ADC driver designs |
| Output current | ±100mA per channel - drives 75Ω video cables or laser diodes without external buffers |
| Supply voltage range | 2.5V to 5.5V - compatible with single-supply 3.3V and dual-supply ±2.5V systems |
| 0.1dB gain flatness | 40MHz - ensures amplitude fidelity in RGB video and ultrasound imaging signals |
| Input bias current | 3pA - minimizes DC error in high-impedance sensor interfaces like photodiodes |
Pinout & Package
TLV3544IDR is available in 14-pin SOIC (D) and TSSOP (PW) packages, both measuring 8.65mm × 3.91mm (SOIC) or 5.00mm × 4.40mm (TSSOP), with identical pinout and thermal characteristics.

| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs - part of complementary CMOS input pair enabling rail-to-rail common-mode range |
| 3, 5, 10, 12 | +IN A/B/C/D | Non-inverting inputs - support full supply-range input with <3pA bias current |
| 4 | V+ | Positive supply terminal - accepts 2.5V to 5.5V; powers all four amplifiers |
| 11 | V– | Negative supply terminal - referenced to system ground in single-supply operation |
Key Features

Applications
| ADC Driver Amplifier | Video Line Driver |
|---|---|
Use Scenario: Driving the analog input of medium-to-high-speed SAR or pipeline ADCs (e.g., ADS7816, ADS7864) with fast settling and minimal charge injection. IC Role / Device Role / Timing Role: Buffer and gain-stage amplifier providing 60ns 0.01% settling to match ADC sampling clocks up to ~10 MSPS.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4350UA | Lower bandwidth (38MHz), lower noise (5.5nV/√Hz), higher quiescent current (8.5mA/ch), no thermal shutdown | Better DC precision and noise; unsuitable for >40MHz video or fast-settling ADC drivers | Select TLV3544IDR for bandwidth-critical applications; OPA4350UA where ultra-low noise and offset dominate |
| LMH6644MA | Higher bandwidth (130MHz), higher slew rate (160V/μs), higher supply current (12.5mA/ch), no rail-to-rail input | Superior speed in non-rail-to-rail systems; incompatible with single-supply 0–3.3V sensor interfaces | Choose TLV3544IDR for rail-to-rail input flexibility and lower power; LMH6644MA only if >100MHz small-signal BW is mandatory and input range allows |
Compared with OPA4350UA and LMH6644MA, TLV3544IDR uniquely balances 200MHz bandwidth, rail-to-rail I/O, 3pA bias current, and thermal protection in a 14-pin SOIC/TSSOP - making it optimal for cost-sensitive, space-constrained, single-supply high-frequency signal chains.

FAQ
What is the maximum operating temperature range for TLV3544IDR?
The TLV3544IDR is specified for operation from –40°C to +125°C ambient temperature. Its internal thermal shutdown activates at 160°C junction temperature and resets at 140°C, providing protection under sustained overload or poor PCB thermal design. This extended range supports deployment in automotive engine compartments and industrial motor-control enclosures where ambient temperatures exceed standard commercial limits.
Does TLV3544IDR support single-supply operation?
Yes, TLV3544IDR fully supports single-supply operation from 2.5V to 5.5V. Its rail-to-rail input common-mode range extends 100mV beyond both supply rails, and its output swings within 100mV of V+ and V– into 1kΩ loads. This enables direct interfacing with 0–3.3V sensors, ADC references, and microcontroller I/O without level-shifting circuitry - simplifying designs in portable and battery-powered systems.
What is the settling time specification for TLV3544IDR?
The TLV3544IDR achieves 0.1% settling in 30ns and 0.01% settling in 60ns for a 2V output step under G = +1, VS = 5V conditions. This performance is enabled by its 150V/μs slew rate and 200MHz unity-gain bandwidth. These values are measured per channel and remain consistent across all four amplifiers in the TLV3544IDR, making it suitable for multiplexed high-speed data acquisition systems.
Can TLV3544IDR drive 75Ω video cables directly?
Yes, TLV3544IDR can directly drive 75Ω video cables in back-terminated configurations. Its ±100mA output current capability and 0.02% differential gain / 0.09° differential phase error meet NTSC broadcast specifications. When used with a 604Ω series resistor and 75Ω termination (as shown in TI's Figure 6-3), it delivers flat frequency response to 40MHz with minimal group delay - eliminating need for external video amplifiers in RGB or CVBS signal paths.
Is TLV3544IDR pin-compatible with other TLV354x variants?
No, TLV3544IDR is not pin-compatible with TLV3541 or TLV3542 due to differing channel counts and pin assignments. TLV3544IDR uses a 14-pin SOIC/TSSOP layout with dedicated pins for four independent channels (e.g., pins 1/7/8/14 = OUT A/B/C/D), whereas TLV3542 uses an 8-pin layout and TLV3541 uses 5- or 8-pin packages. Board redesign is required when substituting between TLV354x family members.
