Product details
Overview
THS4062IDGNR 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%, driving ±11.5 V into 250 Ω with ±15 V supplies. It operates across ±4.5 V to ±16.5 V dual supplies and supports professional NTSC video with 0.02% differential gain and 0.02° differential phase error.
For engineers reviewing the THS4062IDGNR datasheet, THS4062IDGNR pinout, THS4062IDGNR application, or THS4062IDGNR equivalent, this page provides verified technical context, package-validated pin functions, real-world video and line-driver use cases, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The THS4062IDGNR uses a dielectrically isolated complementary bipolar process enabling GHz fT transistors, delivering wide bandwidth and low distortion in a voltage-feedback architecture. Its internal compensation ensures stability at all gains for both inverting and noninverting configurations without external components.
It features dual independent amplifiers sharing no internal coupling beyond substrate-confirmed by 65 dB channel-to-channel crosstalk at 1 MHz-and includes dedicated null pins (1 and 8) for offset trimming. The DGN package integrates PowerPAD™ thermal enhancement requiring PCB thermal plane connection for rated 1.37 W dissipation at 70°C ambient.
Key Specifications

|---|---|
| Small-signal BW (−3 dB) | 180 MHz at G = 1, ±15 V - enables baseband video and fast pulse amplification without roll-off |
| Slew rate | 400 V/µs at ±15 V - supports full-scale 5-V step transitions in ≤12.5 ns with minimal slewing distortion |
| Settling time (0.1%) | 40 ns for 5-V step - meets broadcast video timing requirements for composite sync and active line transitions |
| Differential gain/phase | 0.02% / 0.02° at NTSC 40 IRE - preserves color fidelity in SD video distribution and encoding systems |
| Output drive | ±11.5 V into 250 Ω at ±15 V - drives 75-Ω coaxial lines directly with 20-Ω series isolation resistor |
| Supply range | ±4.5 V to ±16.5 V dual supply - compatible with legacy ±5 V, ±12 V, and ±15 V analog subsystems |
| Total harmonic distortion | −72 dBc at 1 MHz - ensures clean signal reproduction in IF amplification and ADC driver stages |
Pinout & Package
The THS4062IDGNR is housed in an 8-pin HVSSOP (DGN) package with exposed PowerPAD™ thermal pad on the underside, requiring solder connection to a PCB thermal plane per TI design guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Null (Channel 1) | Offset null adjustment terminal for Channel 1; connect potentiometer wiper to −VCC |
| 2 | Inverting input (Channel 1) | High-impedance differential input node; requires short trace routing to minimize parasitic capacitance |
| 3 | Noninverting input (Channel 1) | High-impedance differential input node; referenced to system ground or common-mode bias |
| 4 | −VCC | Negative supply rail; must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum capacitors |
| 5 | −VCC (Channel 2) | Shared negative supply rail for both channels; not electrically isolated between amplifiers |
| 6 | Output (Channel 2) | Capable of sourcing/sinking 115 mA; requires series resistor ≥20 Ω when driving >10 pF loads |
| 7 | Inverting input (Channel 2) | Independent input for second channel; layout symmetry recommended vs. Channel 1 |
| 8 | Null (Channel 2) | Offset null adjustment terminal for Channel 2; functionally identical to Pin 1 |

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 |
|---|---|---|---|
| THS4032IDGNR | 100 MHz bandwidth, 220 V/µs slew rate, lower quiescent current (5.3 mA/ch) | Lower bandwidth limits use in HD video; better suited for low-power IF and sensor interfaces | Select when power efficiency > speed; not suitable for NTSC/PAL video distribution |
| OPA2691IDGNR | 320 MHz bandwidth, 2100 V/µs slew rate, higher THD (−62 dBc at 1 MHz) | Higher speed but reduced linearity; requires careful layout to manage instability at G = 1 | Select for >200 MHz applications where distortion tolerance exceeds −65 dBc |
Compared with THS4062IDGNR, THS4032IDGNR trades 80 MHz bandwidth for 30% lower supply current, while OPA2691IDGNR doubles bandwidth at the cost of 10 dB higher THD and stricter layout sensitivity-making THS4062IDGNR the optimal balance for broadcast-grade video and general-purpose high-fidelity analog signal paths.

FAQ
What is the operating temperature range for the THS4062IDGNR?
The THS4062IDGNR is rated for industrial operation from −40°C to +85°C, as indicated by the "I" suffix in the part number. This range is validated across all electrical specifications including bandwidth, slew rate, and differential gain/phase error, making it suitable for outdoor video enclosures and factory-floor instrumentation where ambient temperatures exceed commercial limits.
Does the THS4062IDGNR require external compensation for unity-gain stability?
No, the THS4062IDGNR is internally compensated for unity-gain stability in both inverting and noninverting configurations. Its design maintains phase margin across all gains without external components. For optimal settling behavior in G = +1 applications, TI recommends a 270 Ω feedback resistor to minimize peaking and ringing-verified in the THS4062IDGNR evaluation board schematic.
Can the THS4062IDGNR drive a 75-Ω coaxial cable directly?
Yes, the THS4062IDGNR can drive a 75-Ω coaxial cable directly when configured as a line driver with appropriate series isolation. TI's application notes specify using a 20–75 Ω resistor in series with the output to isolate capacitive load effects and match source impedance. At ±15 V supply, it delivers ±11.5 V into 250 Ω, enabling full-swing 1 VPP video signals into 75 Ω with headroom.
What is the purpose of Pins 1 and 8 on the THS4062IDGNR?
Pins 1 and 8 are independent offset null terminals for Channel 1 and Channel 2, respectively. Each connects to a potentiometer wiper tied to −VCC, allowing fine adjustment of input offset voltage. This feature is retained from the THS4061/2 architecture and is documented in Figure 26 of the THS4062IDGNR datasheet for precision DC-coupled applications requiring sub-mV offset control.
How does the PowerPAD™ in the DGN package affect thermal design?
The PowerPAD™ on the THS4062IDGNR's underside acts as a thermal conduction path to the PCB. TI specifies that it must be soldered to a dedicated copper thermal plane; failure to do so reduces maximum power dissipation from 1.37 W (at 70°C ambient) to <500 mW. Thermal vias under the pad and ≥4 cm² copper area are required to maintain junction temperature below 150°C under full-load conditions.
