Product details
Overview
THS4062IDR from Texas Instruments is a dual-channel, high-speed voltage-feedback operational amplifier optimized for video, imaging, and communication signal conditioning. It delivers 180 MHz small-signal bandwidth (G = 1), 400 V/µs slew rate, and 40 ns settling time to 0.1%, operating from ±4.5 V to ±16.5 V supplies. Its low 0.02% differential gain and 0.02° differential phase errors enable broadcast-quality analog video line driving.
For engineers reviewing the THS4062IDR datasheet, THS4062IDR pinout, THS4062IDR application, or THS4062IDR equivalent, this page provides verified specifications, SOIC-8 package details, dual-channel video driver use cases, and validated alternative options for high-fidelity analog signal paths requiring wide bandwidth and low distortion.
Technical Context
The THS4062IDR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling stable unity-gain operation in both inverting and noninverting configurations without external compensation. Its voltage-feedback architecture supports fast transient response and minimal phase margin trade-offs across gain settings.
It features internal frequency compensation optimized for wideband performance while maintaining stability at all gains, with design provisions for offset nulling (via pins 1 and 8) and capacitive load isolation (recommended 20 Ω series output resistor). Channel-to-channel crosstalk is −65 dB at 1 MHz, confirming tight dual-channel isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 180 MHz at G = 1, ±15 V supply - enables full HD video baseband amplification without roll-off |
| Slew rate | 400 V/µs at ±15 V - supports fast edge fidelity in pulse and composite video signals |
| Settling time (0.1%) | 40 ns for 5-V step - ensures accurate pixel-level reconstruction in high-speed imaging systems |
| Differential gain/phase | 0.02% / 0.02° at NTSC, G = 2, ±15 V - meets broadcast video color fidelity requirements |
| Output drive current | 115 mA typical per channel into 20 Ω - drives 75 Ω coaxial lines directly with headroom |
| Total harmonic distortion | −72 dBc at 1 MHz - preserves signal purity in RF IF stages and ADC front-ends |
| Supply voltage range | ±4.5 V to ±16.5 V dual supply - accommodates legacy ±5 V and high-dynamic-range ±15 V systems |
Pinout & Package
THS4062IDR is supplied in an 8-pin SOIC (D) package with exposed pad thermal enhancement. The package is RoHS-compliant, moisture-sensitive level 1, and rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-current, low-impedance output node; requires 20 Ω series resistor for >10 pF capacitive loads |
| 1IN− | Channel 1 inverting input | High-impedance node sensitive to layout parasitics; must be routed with minimal trace length |
| 1IN+ | Channel 1 noninverting input | Reference point for single-ended or differential input configurations; matched to 1IN− for CMRR |
| −VCC | Negative supply rail | Connects to system ground or negative rail; decoupling capacitor required within 0.1 inch |
| VCC+ | Positive supply rail | Accepts up to +16.5 V; requires dedicated 0.1 µF ceramic + 6.8 µF tantalum decoupling |
| 2OUT | Channel 2 output | Independent output with identical drive capability and settling behavior as 1OUT |
| 2IN− | Channel 2 inverting input | Electrically isolated from Channel 1 inputs; −65 dB crosstalk at 1 MHz confirms separation |
| 2IN+ | Channel 2 noninverting input | Enables dual independent gain stages or parallel processing of stereo/video Y/C signals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032IDR | 100 MHz bandwidth, lower power (5.3 mA/ch), higher input noise (10 nV/√Hz) | Better suited for battery-powered portable instruments where bandwidth ≤100 MHz suffices | Select when power budget is constrained and 180 MHz is unnecessary; not drop-in due to lower slew rate (270 V/µs) |
| OPA2691U | 320 MHz bandwidth, 1900 V/µs slew rate, higher quiescent current (12.5 mA/ch) | Required for >200 MHz applications such as digital video equalization or optical receiver TIA post-amplification | Choose for next-generation bandwidth headroom; requires updated layout for higher-speed stability and decoupling |
Compared with THS4062IDR, THS4032IDR trades bandwidth and slew rate for lower power and cost in mid-speed video, while OPA2691U extends performance for emerging high-definition serial interfaces-neither is pin-compatible, and PCB redesign is needed for either replacement.

FAQ
What is the operating temperature range for THS4062IDR?
The THS4062IDR is rated for −40°C to +85°C free-air operating temperature, indicated by the "I" suffix in the part number. This industrial-grade range supports deployment in outdoor video enclosures, factory-floor test equipment, and medical imaging systems without derating under ambient thermal stress.
Does THS4062IDR require external compensation for unity-gain stability?
No, the THS4062IDR is internally compensated and remains stable at unity gain in both inverting and noninverting configurations without external components. Its design maintains minimum phase margin for G = +1, though a 270 Ω feedback resistor is recommended to minimize ringing in fast-edge applications.
Can THS4062IDR drive 75 Ω coaxial cable directly?
Yes, THS4062IDR delivers 115 mA per channel and supports ±3.5 V output swing into 1 kΩ, and ±3.2 V into 150 Ω. When configured as a gain-of-2 line driver with proper termination, it meets SMPTE 253M requirements for 75 Ω broadcast video distribution without additional buffering.
What is the purpose of pins 1 and 8 on THS4062IDR?
Pins 1 and 8 are null terminals for offset voltage adjustment. Connecting a 10 kΩ potentiometer between them-with the wiper tied to −VCC-allows fine-tuning of input offset to <0.5 mV in precision DC-coupled applications such as medical sensor signal chains where baseline drift must be minimized.
Is THS4062IDR compatible with SOIC-8 PCB footprints used for other TI op-amps?
Yes, THS4062IDR uses the standard SOIC-8 (D) package with 1.27 mm pitch and 3.9 mm body width, matching footprint dimensions of industry-standard op-amps like OPA2350 or TL072. Thermal pad variants (e.g., DGN) differ and are not footprint-compatible.
