Product details
Overview
TLV3542IDR from Texas Instruments is a dual-channel, rail-to-rail input/output, CMOS operational amplifier optimized for high-speed 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. It serves as an ADC driver, video line driver, or photodiode transimpedance amplifier in low-voltage, high-frequency applications.
For engineers reviewing the TLV3542IDR datasheet, TLV3542IDR pinout, TLV3542IDR application, or TLV3542IDR equivalent, this page provides verified specifications, SOIC-8 package details, dual-channel functional context, thermal shutdown behavior, and validated alternative op amps for video, sensing, and data acquisition designs.
Technical Context
The TLV3542IDR employs a complementary CMOS input stage enabling rail-to-rail input common-mode range extending 100mV beyond both supply rails, paired with a class AB output stage delivering 100mV rail-to-rail swing into 1kΩ at full temperature range (–40°C to +125°C). Its voltage-feedback architecture ensures unity-gain stability while supporting 0.1dB gain flatness up to 40MHz.
It integrates thermal shutdown activation at 160°C and recovery at 140°C, supports single- or dual-supply operation down to ±1.25V, and achieves –100dB channel-to-channel crosstalk at 5MHz-critical for dual-channel precision timing and differential signal paths in baseband and optical interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 200MHz - enables stable closed-loop operation at G = +1 with minimal phase margin degradation |
| Slew rate | 150V/μs - supports clean 2V step response in ≤11ns without slewing distortion |
| Input voltage noise | 7.5nV/√Hz at 1MHz - preserves SNR in wideband sensor and ADC front-end applications |
| Output current | ±100mA - drives 75Ω video cables or laser diodes directly without external buffers |
| Supply range | 2.5V to 5.5V - compatible with Li-ion, USB, and industrial 3.3V/5V rails without level shifting |
| Input bias current | 3pA - minimizes DC error in high-impedance photodiode and precision reference circuits |
| Thermal shutdown | Activates at 160°C, resets at 140°C - protects against sustained overload in compact layouts |
Pinout & Package
TLV3542IDR is housed in an 8-pin SOIC (D) package measuring 3.91mm × 4.90mm, with standard JEDEC MS-012AC footprint and 1.27mm pitch. Thermal resistance RθJA is 113.9°C/W, suitable for moderate-power PCB layouts without forced airflow.
| Pin | 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 | Used in inverting configurations; matched with +IN A for differential gain control |
| OUT A | Output, Channel A | Delivers rail-to-rail swing (within 100mV of rails) into ≥1kΩ loads; capable of ±100mA sourcing/sinking |
| V– | Negative supply terminal | Reference for both channels; must be connected to lowest system potential (e.g., ground in single-supply) |
| +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 independent inverting gain per channel; supports dual-signal processing without cross-talk |
| OUT B | Output, Channel B | Provides identical performance to OUT A; –100dB crosstalk at 5MHz ensures isolation |
| V+ | Positive supply terminal | Supplies both amplifiers; accepts 2.5V–5.5V; bypassing with 100nF ceramic near pin is recommended |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2355IDR | 250MHz GBW, 350V/μs slew rate, higher quiescent current (7.5mA/ch), no thermal shutdown | Better for >50MHz small-signal amplification but less robust under sustained overload | Select when bandwidth >200MHz is mandatory and thermal margin is managed externally |
| LMH6629MF/NOPB | 1.5GHz GBW, 1000V/μs slew rate, 5.5mA/ch, no rail-to-rail output (clips ~1.2V from rails) | Superior for RF IF stages but incompatible with low-voltage ADC inputs requiring full rail swing | Select for GHz-range intermediate frequency amplification where output headroom >1.2V is acceptable |
Compared with TLV3542IDR, OPA2355IDR trades thermal safety for extra bandwidth and speed, while LMH6629MF/NOPB sacrifices rail-to-rail output and supply flexibility for extreme RF performance-making TLV3542IDR the balanced choice for video, ADC, and optical sensing where reliability, voltage range, and noise matter most.

FAQ
What is the maximum capacitive load the TLV3542IDR can drive stably in unity-gain configuration?
The TLV3542IDR maintains stability with ≥100pF capacitive loads in unity-gain configuration when a 10Ω–20Ω series resistor is added at the output. Without RS, instability may occur above ~30pF; Figure 5-7 in the datasheet specifies 47.5Ω RS for 47pF and 34.8Ω for 100pF. This behavior is confirmed across –40°C to +125°C and applies directly to TLV3542IDR's SOIC-8 package layout.
Does TLV3542IDR support true rail-to-rail output swing into 75Ω loads?
Yes - TLV3542IDR delivers rail-to-rail output swing into 75Ω when back-terminated, as shown in Figure 6-3. With proper 75Ω source and load termination, the effective load is resistive (150Ω), avoiding capacitive loading effects. Output swing remains within 100mV of rails at 40MHz, meeting NTSC differential gain/phase specs - a verified capability of TLV3542IDR in video line driver applications.
Can TLV3542IDR operate from a single 2.7V supply while maintaining full AC performance?
Yes - TLV3542IDR is fully specified from 2.5V to 5.5V. At 2.7V, it retains 200MHz unity-gain bandwidth, 150V/μs slew rate, and 7.5nV/√Hz noise density per the Electrical Characteristics table (Section 5.7). Common-mode input range extends from (V–) − 0.1V to (V+) + 0.1V, enabling direct interface with 2.7V-referenced sensors - a confirmed operating condition for TLV3542IDR.
What is the channel-to-channel crosstalk specification for TLV3542IDR?
TLV3542IDR exhibits –100dB channel-to-channel crosstalk at 5MHz, as measured and published in Figure 5-18 and Table 5-7 of the datasheet. This value is specific to the dual-channel TLV3542 variant (including TLV3542IDR) and reflects isolation between Channel A and Channel B under small-signal conditions - critical for dual-path signal processing where interference must remain below –100dB.
Is thermal shutdown active in TLV3542IDR, and what are its thresholds?
Yes - TLV3542IDR includes integrated thermal shutdown that activates at +160°C junction temperature and resets automatically when junction cools to +140°C. This hysteresis is documented in Section 5.7 (Electrical Characteristics) and Section 6.3.4. The feature is inherent to the TLV3542IDR die and functions independently of external circuitry, protecting against sustained overload in compact PCB layouts.
