Product details
Overview
THS4062CD from Texas Instruments is a dual-channel, high-speed voltage-feedback operational amplifier designed for precision 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 V supplies. Its dual-channel architecture enables synchronous analog processing in broadcast video line drivers and CCD signal chains.
For engineers reviewing the THS4062CD datasheet, THS4062CD pinout, THS4062CD application, or THS4062CD equivalent, key selection criteria include its 75 MHz 0.1 dB flatness for composite video, 0.02% differential gain / 0.02° differential phase error at ±15 V, −72 dBc THD at 1 MHz, and dual-channel crosstalk of 65 dB - all validated under standard C-suffix (0°C to 70°C) operating conditions.
Technical Context
The THS4062CD employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling wideband voltage-feedback operation stable at all gains in both inverting and noninverting configurations. Its internal compensation targets unity-gain stability while preserving bandwidth and slew rate.
Each channel features independent input stage nulling capability (pins 1 and 8), rail-to-rail output swing up to ±13.5 V (RL = 1 kΩ, ±15 V supply), and low 12 Ω open-loop output resistance. Channel-to-channel crosstalk is specified at 65 dB (f = 1 MHz), confirming isolation suitable for dual-path analog signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 180 MHz at G = 1, ±15 V - supports baseband video 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 - ensures accurate multi-level video sampling and ADC driver performance |
| Differential gain/phase | 0.02% / 0.02° at NTSC, ±15 V - meets broadcast-grade video fidelity requirements |
| THD | −72 dBc at f = 1 MHz - minimizes harmonic contamination in high-fidelity analog signal paths |
| Supply range | ±4.5 V to ±16 V dual supply - accommodates legacy ±5 V and industrial ±12 V/±15 V systems |
| Quiescent current | 7.8 mA per channel at ±15 V - balances speed and power efficiency for dual-channel designs |
Pinout & Package
THS4062CD is housed in an 8-pin SOIC (D) package with exposed pad thermal enhancement. Pin assignments are identical for both channels and follow industry-standard dual op-amp layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 null adjust | Connects to external potentiometer wiper for fine offset trimming; unused pins must be left open or tied to VCC− |
| 2 | Channel 1 inverting input | Inverting node for feedback configuration; requires short trace and ground plane removal to minimize parasitic capacitance |
| 3 | Channel 1 noninverting input | High-impedance input (1 MΩ) with ±14.1 V common-mode range at ±15 V supply |
| 4 | VCC− | Negative supply rail; decoupling capacitor (0.1 µF ceramic + 6.8 µF tantalum) required within 0.1 inch |
| 5 | VCC+ | Positive supply rail; same decoupling requirement as VCC−; shared supply rails permissible for dual-channel use |
| 6 | Channel 1 output | Capable of ±13.5 V swing into 1 kΩ; series resistor (≥20 Ω) required for >10 pF capacitive loads |
| 7 | Channel 2 inverting input | Independent second channel input; layout symmetry recommended to match channel 1 parasitics |
| 8 | Channel 2 null adjust | Same function as pin 1; not internally connected to channel 1 null; allows independent trimming per channel |
Key Features
| Feature | Design Value |
|---|---|
| Stable at all gains | Internally compensated for unconditional stability in both inverting and noninverting configurations, eliminating external compensation components |
| High output drive | 115 mA continuous output current per channel enables direct driving of 75 Ω video lines or multiple 150 Ω loads |
| Low distortion | −72 dBc THD at 1 MHz ensures minimal spectral regrowth in RF IF stages and high-resolution data acquisition front-ends |
| Video-optimized AC performance | 75 MHz 0.1 dB flatness and <0.02% differential gain error meet SMPTE 259M and ITU-R BT.601 broadcast standards |
| Dual-channel isolation | 65 dB channel-to-channel crosstalk at 1 MHz supports independent signal paths in stereo audio, dual ADC drivers, or X/Y axis instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032CD | 100 MHz bandwidth, lower 10 nV/√Hz noise, but only 200 V/µs slew rate and 70 ns settling time | Better suited for low-noise, medium-speed applications like audio preamps; insufficient for 75 MHz video flatness | Select THS4032CD when noise dominates over speed; avoid for broadcast video or fast ADC driving |
| OPA2691ID | 320 MHz bandwidth, 1800 V/µs slew rate, but higher 12.5 mA/channel quiescent current and no null pins | Targeted at RF/IF gain blocks and optical receiver TIA post-amplifiers; lacks video-optimized differential specs | Choose OPA2691ID for >200 MHz signal chains where THS4062CD's 180 MHz limit is exceeded; verify THD and gain flatness separately |
Compared with THS4062CD, THS4032CD trades bandwidth and slew for lower noise and power, while OPA2691ID extends frequency capability at the cost of video-specific accuracy and trim flexibility - making THS4062CD the optimal choice for broadcast-qualified dual-channel analog signal conditioning.

FAQ
What is the maximum supply voltage rating for THS4062CD?
The THS4062CD has an absolute maximum supply voltage rating of ±16.5 V (33 V total across VCC+ and VCC−). Operation beyond this risks permanent damage. The recommended operating range is ±4.5 V to ±16 V for dual supply, or 9 V to 32 V for single supply. Derating applies above 25°C ambient - for example, D-package power dissipation drops from 740 mW at 25°C to 475 mW at 70°C.
Does THS4062CD support single-supply operation?
Yes, THS4062CD supports single-supply operation from 9 V to 32 V. Its input common-mode range extends to within 1.2 V of the negative rail (e.g., 1.2 V above ground at 9 V supply), and output can swing to within 1.5 V of either rail under typical loads. For rail-to-rail input/output behavior, external level-shifting or biasing is required - the device itself is not rail-to-rail.
How is THS4062CD's dual-channel crosstalk characterized?
THS4062CD specifies 65 dB channel-to-channel crosstalk at f = 1 MHz under ±5 V or ±15 V supply conditions. This measurement reflects signal coupling from one channel's output to the other channel's input, verified per Figure 24 test circuit in the datasheet. Crosstalk degrades with frequency - at 100 MHz it falls to ~40 dB - so layout isolation remains critical in wideband applications.
Can THS4062CD drive 75 Ω video loads directly?
Yes, THS4062CD can drive 75 Ω video loads directly. At ±15 V supply, it delivers ±3.5 V output swing into 75 Ω (per Figure 17), sufficient for 1 VPP composite video. For optimal impedance matching and capacitive load stability, TI recommends adding a 75 Ω series resistor at the output - this isolates stray capacitance while establishing proper source termination per SMPTE standards.
What evaluation module is available for THS4062CD?
The THS4062EVM (literature number SLOP235) is the official evaluation module for THS4062CD. It features low-parasitic layout, configurable inverting/noninverting gain settings, and provisions for dual-channel independent testing. The board supports both SOIC (D) and MSOP (DGN) packages and includes optimized decoupling per TI's high-frequency layout guidelines.
