Product details
Overview
TLV3542IDGKR 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 and high-resolution ADC buffering in 2.5V–5.5V systems.
For engineers reviewing the TLV3542IDGKR datasheet, TLV3542IDGKR pinout, TLV3542IDGKR application, or TLV3542IDGKR 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 specified operation from –40°C to +125°C.
Technical Context
The TLV3542IDGKR employs a complementary input stage (N- and P-channel differential pairs) to achieve rail-to-rail input common-mode range extending 100mV beyond supply rails. Its class AB output stage supports rail-to-rail output swing with <100mV headroom into 1kΩ loads across temperature.
This dual op amp features unity-gain stability, 0.1dB gain flatness to 40MHz, differential gain/phase error of 0.02%/0.09° (NTSC), and channel-to-channel crosstalk of –100dB at 5MHz - confirming suitability for RGB video and multi-channel precision analog front-ends.
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 fast 2V step response with 30ns 0.1% settling time |
| Input voltage noise | 7.5nV/√Hz at 1MHz - critical for low-noise photodiode transimpedance and ADC driver applications |
| Output current | ±100mA - drives 75Ω video cables or laser diodes without external buffers |
| Supply voltage range | 2.5V to 5.5V - operates from single 3.3V or 5V rails, or split ±1.25V to ±2.75V supplies |
| Input bias current | 3pA - minimizes DC error in high-impedance sensor interfaces and transimpedance amplifiers |
| Quiescent current | 5.2mA per channel - balances speed and power efficiency for battery-sensitive designs |
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 signal referenced to V–; supports rail-to-rail common-mode range (V– − 0.1V to V+ + 0.1V) |
| –IN A | Inverting input, Channel A | Feedback node for inverting configurations; matched input impedance to +IN A |
| OUT A | Output, Channel A | Delivers rail-to-rail swing (within 100mV of V–/V+) into ≥1kΩ loads at full bandwidth |
| +IN B | Non-inverting input, Channel B | Independent input for second signal path; no internal coupling to Channel A |
| –IN B | Inverting input, Channel B | Enables dual independent amplifiers on single die - reduces board space vs discrete solutions |
| OUT B | Output, Channel B | Provides identical AC performance and DC specs as OUT A; –100dB crosstalk at 5MHz |
| V– | Negative supply terminal | Reference for both channels; must be connected to lowest system potential (e.g., ground or negative rail) |
| V+ | Positive supply terminal | Power source for both amplifiers; supports 2.5V–5.5V operation with thermal shutdown at 160°C |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in low-voltage (3.3V/5V) systems - input extends 100mV beyond rails, output swings to within 100mV of rails |
| 200MHz unity-gain bandwidth | Supports high-fidelity video signal amplification (NTSC/PAL) and fast-settling ADC drivers without peaking or instability |
| Thermal shutdown protection | Automatically disables output above 160°C junction temperature; resumes operation below 140°C - prevents permanent damage during overload |
| Low 3pA input bias current | Reduces offset drift in high-impedance transducer interfaces (e.g., photodiodes, pH sensors) and maintains accuracy over temperature |
| 0.1dB gain flatness to 40MHz | Ensures minimal amplitude distortion in wideband video and communication signals - meets broadcast-grade video specifications |
Applications

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 |
|---|---|---|---|
| OPA2355IDGKR | 250MHz GBW, 350V/μs slew rate, higher quiescent current (7.5mA/ch), no thermal shutdown | Better suited for ultra-high-speed pulse amplification where >200MHz bandwidth is mandatory | Select OPA2355IDGKR only when 250MHz bandwidth and 350V/μs slew rate are required and thermal protection is handled externally |
| LMH6629MA/NOPB | 850MHz GBW, 1200V/μs slew rate, higher noise (10.5nV/√Hz), ±15V supply capable | Targeted at high-voltage, ultra-wideband RF and test equipment - not optimized for 3.3V/5V low-power systems | Choose LMH6629MA/NOPB for >500MHz applications with ±5V or higher supplies; avoid for cost-sensitive, low-voltage designs |
Compared with OPA2355IDGKR and LMH6629MA/NOPB, TLV3542IDGKR offers optimal balance of 200MHz bandwidth, rail-to-rail operation at 2.5V–5.5V, integrated thermal protection, and 5.2mA/ch quiescent current - making it the preferred choice for video, ADC driver, and portable high-speed analog signal chains.

FAQ
What is the operating temperature range for TLV3542IDGKR?
The TLV3542IDGKR is fully specified from –40°C to +125°C ambient temperature. Its thermal shutdown circuit activates at 160°C junction temperature and resets at 140°C, ensuring reliable operation across industrial and automotive under-hood environments. All electrical characteristics in the datasheet are guaranteed within this range.
Does TLV3542IDGKR support single-supply operation?
Yes, TLV3542IDGKR supports true single-supply operation from 2.5V to 5.5V. Its rail-to-rail input extends 100mV beyond both supply rails, and its output swings to within 100mV of V– and V+, enabling full-scale signal handling in 3.3V or 5V systems without level-shifting circuitry.
What is the maximum capacitive load TLV3542IDGKR can drive stably?
TLV3542IDGKR maintains stability with capacitive loads up to 100pF in unity-gain configuration when a series resistor (RS) of 34.8Ω is used, as documented in Figure 5-7 of the datasheet. For larger loads, RS must be increased - e.g., 47.5Ω for 47pF - to preserve phase margin and prevent peaking.
How does TLV3542IDGKR compare to TLV3541 and TLV3544 in pin compatibility?
TLV3542IDGKR (VSSOP-8) is not pin-compatible with TLV3541 (SOT-23-5 or SOIC-8) or TLV3544 (SOIC-14/TSSOP-14). Each variant has distinct pin counts and assignments: TLV3542IDGKR uses all 8 pins for dual-channel I/O and supplies, while TLV3541 omits one input pair and TLV3544 adds four more I/O terminals - requiring separate PCB layouts.
Can TLV3542IDGKR drive a 75Ω video cable directly?
Yes, TLV3542IDGKR can directly drive a 75Ω video cable in back-terminated configuration, as shown in Figure 6-3 of the datasheet. With proper 75Ω source termination, it achieves 0.02% differential gain and 0.09° differential phase error - meeting NTSC broadcast video performance requirements without external components.
