Product details
Overview
TLV3544IPWR from Texas Instruments is a quad-channel, rail-to-rail input/output, CMOS operational amplifier optimized for high-speed, low-voltage signal conditioning in cost-sensitive systems. 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 precision ADC driver and video line driver functions in compact industrial and medical imaging front-ends.
For engineers reviewing the TLV3544IPWR datasheet, TLV3544IPWR pinout, TLV3544IPWR application, or TLV3544IPWR equivalent, key selection criteria include its quad-channel layout in TSSOP-14, rail-to-rail I/O swing within 100mV of rails, thermal shutdown at 160°C, and verified performance in photodiode transimpedance and fast current-sensing topologies.
Technical Context
The TLV3544IPWR employs a complementary CMOS input stage with parallel N- and P-channel differential pairs to achieve rail-to-rail input operation extending 100mV beyond both supply rails. Its class AB output stage supports high-current drive while maintaining >90dB open-loop gain across temperature.
It is unity-gain stable and specified for –40°C to +125°C operation. The device features integrated thermal shutdown (trip at 160°C, reset at 140°C), low 3pA input bias current, and channel-to-channel crosstalk of –84dB at 5MHz - critical for multi-channel synchronous sampling and RGB video buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 200MHz - enables stable closed-loop operation up to 200MHz in G = +1 configuration for high-frequency signal conditioning. |
| Slew rate | 150V/μs - supports clean 2V step response with 30ns settling to 0.1% and 60ns to 0.01%, suitable for driving medium-speed ADCs. |
| Input voltage noise | 7.5nV/√Hz at 1MHz - minimizes added noise in low-level sensor interfaces like photodiode transimpedance amplifiers. |
| Output current | ±100mA per channel - drives 75Ω video cables, laser diodes, or low-impedance loads without external boost circuitry. |
| Supply range | 2.5V to 5.5V - supports single-supply operation down to 2.5V, ideal for battery-powered or low-voltage embedded systems. |
| Input bias current | 3pA - preserves accuracy in high-impedance sensor nodes and precision reference buffers. |
| Common-mode input range | (V–) – 0.1V to (V+) + 0.1V - enables true rail-to-rail input operation, including ground-referenced signals in single-supply designs. |
| Output swing | Within 100mV of rails (RL = 1kΩ) - maximizes dynamic range in low-voltage applications such as ultrasound front-ends. |
Pinout & Package
TLV3544IPWR is packaged in a 14-pin TSSOP (PW package), 5.00mm × 4.40mm body size, with exposed pad not electrically connected. Pin assignment is identical between TSSOP and SOIC variants per TI SBOS756A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A, OUT B, OUT C, OUT D | Amplifier outputs - each capable of ±100mA drive and rail-to-rail swing; require local bypassing for stability. |
| 2, 6, 9, 13 | –IN A, –IN B, –IN C, –IN D | Inverting inputs - high-impedance CMOS nodes; sensitive to PCB leakage and EMI; guard traces recommended. |
| 3, 5, 10, 12 | +IN A, +IN B, +IN C, +IN D | Non-inverting inputs - support common-mode range beyond rails; match trace lengths to inverting inputs for balanced layout. |
| 4 | V+ | Positive supply terminal - must be decoupled with ≥100nF ceramic capacitor placed ≤2mm from pin. |
| 11 | V– | Negative supply terminal - connects to system ground in single-supply configurations; shares return path with all channels. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal handling in 2.5V–5.5V single-supply systems, eliminating level-shifting circuitry in ADC drivers and video buffers. |
| 200MHz unity-gain bandwidth | Supports wideband applications including barcode scanner signal processing and optical networking pre-amplification up to 40MHz 0.1dB flatness. |
| Thermal shutdown protection | Automatically disables output at 160°C junction temperature and recovers at 140°C - prevents latch-up or permanent damage during overload or poor heatsinking. |
| Low 3pA input bias current | Reduces offset drift in high-source-impedance transducer interfaces (e.g., piezoelectric sensors, pH electrodes) without requiring guard rings or active cancellation. |
| –84dB channel crosstalk @ 5MHz | Maintains signal integrity in multi-channel synchronous acquisition (e.g., 4-channel ultrasound beamforming) without inter-channel interference. |
| 7.5nV/√Hz input voltage noise | Preserves SNR in low-amplitude, high-bandwidth sensor paths - critical for photodiode transimpedance amplifiers in spectrometry and pulse oximetry. |

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 38MHz GBW, higher 11nV/√Hz noise, but superior 150µV max VOS and 0.5µV/°C drift. | Better suited for DC-critical precision instrumentation; less appropriate for >10MHz video or ADC driver use. | Select OPA4350UA when DC accuracy dominates over speed; TLV3544IPWR preferred for bandwidth-critical signal chains. |
| LMH6644MA | Higher 280MHz GBW and 400V/μs slew rate, but consumes 12.5mA/channel and lacks rail-to-rail input. | Requires dual supply or level-shifting for single-supply input; better for RF IF stages than low-voltage embedded video. | Choose LMH6644MA only when >200MHz bandwidth is mandatory and supply headroom allows non-rail I/O operation. |
Compared with OPA4350UA and LMH6644MA, TLV3544IPWR uniquely balances 200MHz bandwidth, rail-to-rail I/O, 5.2mA/channel quiescent current, and 3pA input bias - making it optimal for space-constrained, low-voltage, high-frequency applications where power, noise, and supply flexibility are co-constrained.

FAQ
What is the maximum operating temperature range for TLV3544IPWR?
The TLV3544IPWR is fully specified from –40°C to +125°C ambient temperature. Its internal thermal shutdown activates at 160°C junction temperature and resets at 140°C, protecting the device during sustained overload conditions. This extended range supports deployment in under-hood automotive modules and industrial PLCs without derating.
Does TLV3544IPWR support single-supply operation?
Yes, TLV3544IPWR supports true single-supply operation from 2.5V to 5.5V. Its rail-to-rail input extends 100mV beyond both supply rails, and output swings within 100mV of V+ and V–, enabling ground-referenced signal processing without level-shifting circuitry - a key advantage in battery-powered and portable medical devices.
Can TLV3544IPWR drive a 75Ω video cable directly?
Yes, TLV3544IPWR can drive a 75Ω video cable in a back-terminated configuration, delivering 0.02% differential gain and 0.09° differential phase error for NTSC compliance. Its ±100mA output current and 40MHz 0.1dB gain flatness make it suitable for RGB and composite video line drivers in IR touch and display interfaces.
What is the typical input bias current of TLV3544IPWR?
The typical input bias current of TLV3544IPWR is 3pA at 25°C, with a maximum of ±10pA over temperature. This ultra-low value minimizes voltage error in high-impedance sensor interfaces - such as photodiode transimpedance amplifiers or pH electrode buffers - where even femtoampere leakage degrades accuracy.
Is TLV3544IPWR unity-gain stable?
Yes, TLV3544IPWR is unity-gain stable and characterized for G = +1 operation with 200MHz small-signal bandwidth. It maintains phase margin >45° into capacitive loads up to 100pF when used with recommended series output resistance (e.g., 10Ω–20Ω), as validated in TI SBOS756A Figure 5-7 and Figure 5-8.
