Product details
Overview
TLV3542IDGKT from Texas Instruments is a dual-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 video line driving, ADC front-end buffering, and fast current-sensing in 2.5V–5.5V systems.
For engineers reviewing the TLV3542IDGKT datasheet, TLV3542IDGKT pinout, TLV3542IDGKT application, or TLV3542IDGKT equivalent, key selection criteria include its dual-channel rail-to-rail I/O swing (within 100mV of rails), ±100mA output drive capability, thermal shutdown protection at 160°C, and guaranteed operation from –40°C to +125°C.
Technical Context
The TLV3542IDGKT employs a complementary N/P-channel input stage to achieve rail-to-rail common-mode input range extending 100mV beyond supply rails, paired with a Class AB output stage delivering 100mV rail-to-rail swing into ≥1kΩ loads. Its voltage-feedback architecture ensures unity-gain stability while supporting gain configurations from +1V/V to +10V/V.
Designed for single-supply (2.5V–5.5V) or split-supply (±1.25V to ±2.75V) operation, it integrates on-chip thermal shutdown (trip at 160°C, reset at 140°C) and supports capacitive load drive up to 100pF with external series resistance optimization per Figure 5-7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 200MHz - enables stable amplification of signals up to 200MHz without peaking or oscillation in G = +1 configuration |
| Slew rate | 150V/μs - supports clean 2V step response with ≤30ns 0.1% settling time, critical for fast pulse conditioning |
| Input voltage noise | 7.5nV/√Hz at 1MHz - minimizes added noise in low-level signal chains such as photodiode transimpedance stages |
| Output current | ±100mA - drives 75Ω video cables, laser diodes, or parallel-connected loads without external buffers |
| Supply voltage range | 2.5V to 5.5V - operates from single Li-ion cells (3.0–3.7V) or regulated 3.3V/5V rails with full rail-to-rail I/O functionality |
| Input bias current | 3pA - preserves high-impedance sensor node accuracy in IR touch or photodiode applications |
| Thermal shutdown | Activates at 160°C junction temperature - protects device during sustained overload or poor PCB thermal design |
Pinout & Package
VSSOP-8 (DGK) package: 3.00mm × 3.00mm body, 0.65mm pitch, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A | Non-inverting input, channel A | Accepts differential-mode signal referenced to V–; supports rail-to-rail common-mode range (V– − 0.1V to V+ + 0.1V) |
| –IN A | Inverting input, channel A | Forms feedback node for inverting configurations; matched input impedance to +IN A |
| OUT A | Output, channel A | Delivers rail-to-rail swing (≤100mV from rails into 1kΩ); capable of ±100mA continuous sourcing/sinking |
| +IN B | Non-inverting input, channel B | Independent second channel input; no crosstalk >100dB at 5MHz (typical) |
| –IN B | Inverting input, channel B | Electrically isolated from channel A inputs; enables dual-path signal processing without interaction |
| OUT B | Output, channel B | Independent output stage; maintains full 200MHz bandwidth and 150V/μs slew rate per channel |
| V– | Negative supply terminal | Reference for both channels; must be connected to lowest system potential (e.g., ground in single-supply) |
| V+ | Positive supply terminal | Power rail for both amplifiers; supports up to 5.5V; internal regulation ensures consistent quiescent current (5.2mA/channel) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Common-mode range extends 100mV beyond V– and V+, enabling direct interfacing with sensors or DACs operating near supply rails |
| Dual independent amplifiers | Zero inter-channel crosstalk degradation (<–100dB at 5MHz) allows simultaneous processing of two high-frequency signals (e.g., RGB video channels) |
| Low-noise, high-speed architecture | 7.5nV/√Hz input voltage noise combined with 200MHz bandwidth supports high-fidelity signal acquisition in ultrasound imaging and optical networking |
| Robust capacitive load drive | Stable operation with ≥100pF loads when using recommended series resistor (e.g., 34.8Ω for 100pF), eliminating need for external isolation networks |
| Thermal protection | Integrated shutdown circuit disables output above 160°C junction temperature and auto-resumes below 140°C - prevents latch-up or permanent damage during transient overloads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2355IDGKT | 250MHz GBW, 350V/μs slew rate, higher quiescent current (7.5mA/channel), no thermal shutdown | Better suited for ultra-high-speed pulse amplification but lacks integrated thermal protection and consumes more power | Select OPA2355IDGKT only when >200MHz bandwidth is mandatory and thermal margin is assured by layout/cooling |
| LMH6629MF/NOPB | 800MHz GBW, 1000V/μs slew rate, 1.9nV/√Hz noise, 12mA/channel IQ, SOIC-8 only | Targeted at RF/IF signal chains requiring sub-1ns rise time; not optimized for rail-to-rail I/O or low-voltage operation | Choose LMH6629MF/NOPB for GHz-range small-signal amplification where supply >±5V is available and rail-to-rail swing is unnecessary |
Compared with OPA2355IDGKT and LMH6629MF/NOPB, TLV3542IDGKT provides optimal balance of speed (200MHz), rail-to-rail I/O, low noise (7.5nV/√Hz), and thermal safety in 2.5V–5.5V systems - making it uniquely suitable for cost-sensitive, space-constrained industrial and medical signal paths where reliability and supply flexibility are critical.

FAQ
What is the maximum operating temperature range for TLV3542IDGKT?
The TLV3542IDGKT is specified to operate continuously from –40°C to +125°C ambient temperature. Its internal thermal shutdown activates at 160°C junction temperature and resets at 140°C, providing robust protection during transient overloads or inadequate heatsinking. This extended range supports deployment in under-hood automotive modules, industrial PLCs, and medical imaging equipment where ambient temperatures exceed standard commercial limits.
Does TLV3542IDGKT support single-supply operation?
Yes, TLV3542IDGKT fully supports single-supply operation from 2.5V to 5.5V. Its rail-to-rail input stage accepts common-mode voltages from (V– − 0.1V) to (V+ + 0.1V), and its output swings within 100mV of both rails into ≥1kΩ loads. This enables direct interfacing with 3.3V microcontrollers, 5V ADCs, and single-ended sensors without level-shifting circuitry - simplifying design in battery-powered and space-constrained systems.
Can TLV3542IDGKT drive a 75Ω video cable directly?
Yes, TLV3542IDGKT can drive a 75Ω video cable in back-terminated configuration, as validated in TI's Figure 6-3. With proper termination, it achieves 0.02% differential gain and 0.09° differential phase error for NTSC signals. The amplifier delivers sufficient output current (±100mA) and maintains 40MHz 0.1dB gain flatness, meeting broadcast video performance requirements without external buffers or passive networks.
What is the typical input bias current of TLV3542IDGKT?
The typical input bias current of TLV3542IDGKT is 3pA at 25°C, with a maximum of ±10pA over temperature. This ultra-low value minimizes voltage errors in high-impedance nodes - such as photodiode transimpedance amplifiers, IR touch interfaces, and precision sensor front-ends - where even femtoamp-level leakage would degrade accuracy or cause drift.
Is TLV3542IDGKT unity-gain stable?
Yes, TLV3542IDGKT is explicitly unity-gain stable and characterized for G = +1 operation across its full 200MHz bandwidth. Its voltage-feedback architecture and internal compensation ensure stable step response (≤30ns 0.1% settling) and flat frequency response without external compensation components - simplifying design for buffer, follower, and active filter applications where minimal external parts are required.
