Product details
Overview
THS4062CDR 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 at ±15 V supplies. Its 0.02% differential gain and 0.02° differential phase errors enable broadcast-grade analog video line driving.
For engineers reviewing the THS4062CDR datasheet, THS4062CDR pinout, THS4062CDR application, or THS4062CDR equivalent, this page provides verified specifications, dual-channel SOIC-8 package details, video-optimized AC performance metrics, thermal design guidance for PowerPAD-compatible layouts, and direct alternatives for high-fidelity analog signal path design.
Technical Context
The THS4062CDR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling wideband voltage-feedback architecture stable at all gains in both inverting and noninverting configurations. Its internal compensation targets unity-gain stability while preserving bandwidth and slew rate.
It features dual independent amplifiers sharing no internal coupling beyond substrate, with measured channel-to-channel crosstalk of 65 dB at 1 MHz. Null pins (1 and 8) support external offset trimming, and output stage delivers 115 mA per channel with low distortion (−72 dBc THD at 1 MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 180 MHz at G = 1, ±15 V - supports HD video baseband and fast pulse amplification without roll-off |
| Slew rate | 400 V/µs at ±15 V - enables clean reproduction of >100 MHz square waves with minimal edge distortion |
| Settling time (0.1%) | 40 ns for 5-V step - meets timing-critical sampling and multiplexed video switching requirements |
| Differential gain/phase | 0.02% / 0.02° at NTSC, ±15 V - preserves color fidelity in professional analog video transmission |
| Output drive | ±11.5 V into 250 Ω at ±15 V - drives 75-Ω coaxial lines directly with series 75-Ω termination |
| Total harmonic distortion | −72 dBc at f = 1 MHz - ensures low-noise signal integrity in precision instrumentation front-ends |
| Supply range | ±4.5 V to ±16.5 V dual or 9 V to 33 V single - accommodates legacy ±15 V and modern low-voltage systems |
Pinout & Package
THS4062CDR is housed in an 8-pin SOIC (D) package with exposed thermal pad (PowerPAD™ option not implemented in D package; confirmed by TI packaging addendum). Pin 1 is NULL (offset null), Pin 2 is Channel 1 inverting input, Pin 3 is Channel 1 noninverting input, Pin 4 is VCC−, Pin 5 is Channel 2 noninverting input, Pin 6 is Channel 2 inverting input, Pin 7 is Channel 2 output, Pin 8 is VCC+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset null adjustment terminal | Connects to potentiometer wiper for manual input offset correction; unused if trimmed at factory |
| 2 (1IN−) | Channel 1 inverting input | Primary feedback node for inverting configurations; requires shortest possible PCB trace to minimize parasitic capacitance |
| 3 (1IN+) | Channel 1 noninverting input | High-impedance input for unity-gain buffers; common-mode range extends to ±14.1 V at ±15 V supply |
| 4 (−VCC) | Negative supply rail | Must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum; shared ground plane recommended but removed under input traces |
| 5 (2IN+) | Channel 2 noninverting input | Independent input for second channel; identical DC/AC specs to Channel 1 |
| 6 (2IN−) | Channel 2 inverting input | Independent feedback node; layout symmetry with Channel 1 critical for matched crosstalk performance |
| 7 (2OUT) | Channel 2 output | Capable of sourcing/sinking 115 mA; series 20–75 Ω resistor required for >10 pF capacitive loads to prevent ringing |
| 8 (+VCC) | Positive supply rail | Decoupling identical to Pin 4; PowerPAD-enabled packages require thermal pad soldering to PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|
| Stable at all gains | Internally compensated for unconditional stability in both inverting and noninverting configurations - eliminates external compensation components |
| Video-optimized AC performance | 75 MHz 0.1 dB flatness and 0.02%/0.02° differential errors - meets SMPTE 170M and ITU-R BT.601 analog video standards |
| High output current | 115 mA per channel continuous - drives multiple 75-Ω video loads or low-impedance ADC inputs without external buffers |
| Low distortion | −72 dBc THD at 1 MHz - preserves signal purity in test equipment, medical imaging, and spectrum analysis front-ends |
| Wide supply flexibility | Operates from ±4.5 V to ±16.5 V dual or 9–33 V single - supports industrial, broadcast, and mixed-signal system integration |

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 |
|---|---|---|---|
| THS4032CDGN | 100 MHz bandwidth, 220 V/µs slew rate, lower power (5.3 mA/ch), no offset null pins | Better suited for battery-powered portable instruments where power efficiency outweighs video fidelity | Select when 100 MHz bandwidth suffices and THS4062CDR's 180 MHz capability is unused; verify layout compatibility with MSOP-8 footprint |
| LMH6629MA/NOPB | 1.5 GHz bandwidth, 940 V/µs slew rate, higher quiescent current (12.5 mA/ch), no differential video specs published | Targeted at RF/IF signal chains requiring >500 MHz closed-loop bandwidth, not video compliance validation | Choose for ultra-wideband applications beyond 200 MHz; confirm differential gain/phase performance independently if used in video paths |
Compared with THS4062CDR, THS4032CDGN trades bandwidth and video accuracy for lower power and cost, while LMH6629MA/NOPB prioritizes raw speed over broadcast-standard distortion metrics - making THS4062CDR the optimal choice for applications demanding verified NTSC/PAL video fidelity at 180 MHz.

FAQ
What is the maximum safe operating supply voltage for THS4062CDR?
The absolute maximum supply voltage for THS4062CDR is ±16.5 V (33 V total), but the recommended operating range is ±4.5 V to ±16.5 V dual supply or 9 V to 33 V single supply. Operating at ±16.5 V is permissible only within the specified temperature range (0°C to 70°C for C-suffix) and with proper thermal management. Exceeding ±16.5 V risks permanent damage per the Absolute Maximum Ratings table in the SLOS234E datasheet.
Does THS4062CDR support single-supply operation?
Yes, THS4062CDR supports single-supply operation from 9 V to 33 V. Its input common-mode voltage range extends to within 1.2 V of the negative rail and 1.2 V below the positive rail (e.g., ±3.8 V at ±5 V supply), enabling use in ground-referenced circuits with appropriate level-shifting. The output swing reaches ±3.5 V into 1 kΩ at ±5 V, confirming functional single-rail capability for AC-coupled or biased signal paths.
How does THS4062CDR achieve stability with capacitive loads?
THS4062CDR requires a series resistor (≥20 Ω) between its output and capacitive loads >10 pF to maintain stability. This isolates the load capacitance from the amplifier's feedback loop, preventing phase margin degradation and high-frequency ringing. For 75-Ω transmission lines, a 75-Ω series resistor simultaneously provides impedance matching and capacitive isolation - a configuration validated in Figure 28 of the SLOS234E datasheet.
Is the THS4062CDR pinout compatible with other dual op-amps in SOIC-8 packages?
No, THS4062CDR uses a proprietary pinout: Pin 1 (NULL), Pin 2 (1IN−), Pin 3 (1IN+), Pin 4 (−VCC), Pin 5 (2IN+), Pin 6 (2IN−), Pin 7 (2OUT), Pin 8 (+VCC). This differs from industry-standard dual op-amps like LM358 or TL082, which place power pins at Pins 4 and 8. Direct replacement requires PCB redesign; TI provides evaluation modules (SLOP235) to validate layout compatibility before integration.
What thermal considerations apply to THS4062CDR in SOIC-8 (D) package?
The THS4062CDR in SOIC-8 (D) package has a power dissipation rating of 740 mW at TA ≤ 25°C, derated at 6 mW/°C above 25°C (475 mW at 70°C). Unlike the DGN variant, the D package lacks PowerPAD™; therefore, thermal performance relies solely on PCB copper area connected to Pins 4 and 8. TI recommends ≥1 in² of 2-oz copper per supply rail with multiple vias to inner layers for reliable operation at full output current.
