Product details
Overview
THS4062CDRG4 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 - enabling high-fidelity analog front-end design in broadcast-grade video line drivers and ADC/DAC buffer stages.
For engineers reviewing the THS4062CDRG4 datasheet, THS4062CDRG4 pinout, THS4062CDRG4 application, or THS4062CDRG4 equivalent, key selection criteria include its dual-channel layout, SOIC-8 package compatibility, wide supply range (±4.5 V to ±16.5 V), low differential gain/phase error (0.02%/0.02°), and verified performance at unity-gain stability across inverting and noninverting configurations.
Technical Context
The THS4062CDRG4 employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture with minimal phase margin trade-offs. Its internal compensation ensures unconditional stability at all gains, including unity-gain noninverting mode, while supporting fast transient response without external compensation.
It features matched dual amplifiers sharing common supply rails and thermal environment, with channel-to-channel crosstalk of 65 dB at 1 MHz - critical for multi-channel video reconstruction and simultaneous sampling systems where inter-channel isolation directly impacts image fidelity and timing skew.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 180 MHz at G = 1, ±15 V - supports full HD baseband video bandwidth without roll-off |
| Slew rate | 400 V/µs at ±15 V - enables clean reproduction of fast-edged composite sync pulses and digital video transitions |
| Settling time (0.1%) | 40 ns for 5-V step - meets timing budget for 10-bit+ ADC/DAC interface buffering at ≥10 MSPS |
| Differential gain/phase | 0.02% / 0.02° at NTSC, G = 2, ±15 V - preserves color fidelity in professional SD/HD video distribution |
| Output drive | ±11.5 V into 250 Ω at ±15 V - drives 75-Ω coaxial lines directly with minimal external components |
| Total harmonic distortion | −72 dBc at 1 MHz - maintains SNR integrity in high-dynamic-range instrumentation signal chains |
| Supply voltage range | ±4.5 V to ±16.5 V dual or 9 V to 33 V single - accommodates legacy ±12 V and modern ±5 V systems |
Pinout & Package
THS4062CDRG4 is housed in an 8-pin SOIC (D) package with exposed pad not electrically connected - compatible with standard surface-mount assembly and IPC-7351B footprint D_300X190X100_P1270X1016_EP150X150.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel A output | High-current output node capable of sourcing/sinking 115 mA - connects directly to load or termination resistor |
| 1IN− | Channel A inverting input | High-impedance node requiring short trace routing to minimize parasitic capacitance and maintain bandwidth |
| 1IN+ | Channel A noninverting input | Reference input for single-ended or differential gain configuration; matched to 1IN− for CMRR optimization |
| −VCC | Negative supply rail | Must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum close to pin - critical for PSRR >70 dB |
| VCC+ | Positive supply rail | Shared supply for both channels; requires independent decoupling to prevent inter-channel coupling |
| 2OUT | Channel B output | Electrically identical to 1OUT; enables dual-channel operation without performance degradation |
| 2IN− | Channel B inverting input | Independent input path; crosstalk to Channel A is ≤−65 dB at 1 MHz - suitable for stereo or dual-sensor systems |
| 2IN+ | Channel B noninverting input | Matched offset and bias characteristics to 1IN+ - ensures consistent DC operating point across channels |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| THS4062IDR | Same silicon, −40°C to 85°C temperature grade vs. 0°C to 70°C for THS4062CDRG4; identical electrical specs and SOIC-8 packaging | Required for industrial environments with extended ambient temperature cycling or uncontrolled enclosures | Select THS4062IDR when operating outside 0–70°C range; no PCB or schematic changes needed |
| OPA2691U | Higher 320 MHz bandwidth but lower output drive (80 mA); different pinout (SOIC-8 vs. OPA2691U's SOIC-8 with different terminal mapping) | Preferred for RF/IF gain blocks where bandwidth dominates over video line-driving capability | Choose OPA2691U only if >200 MHz closed-loop bandwidth is mandatory and 75-Ω drive is handled externally |
Compared with THS4062IDR, THS4062CDRG4 offers tighter initial offset and lower cost for commercial-temperature applications; compared with OPA2691U, it provides superior video-specific distortion metrics and higher output current at the expense of bandwidth - making it optimal for precision analog video and medium-speed data acquisition.

FAQ
What is the maximum capacitive load the THS4062CDRG4 can drive without instability?
The THS4062CDRG4 is internally compensated for unity-gain stability but becomes susceptible to ringing with >10 pF direct capacitive loading. For loads exceeding this, a 20–75 Ω series resistor must be placed at the output - e.g., 75 Ω for 75-Ω transmission line matching. This isolates the capacitance and restores phase margin, as confirmed in Figure 28 of the SLOS234E datasheet. THS4062CDRG4 performance remains within spec when this guideline is followed.
Does the THS4062CDRG4 support single-supply operation?
Yes, THS4062CDRG4 operates from a single supply of 9 V to 33 V, with input common-mode range extending to within 3.8 V of each rail at ±5 V supply and output swing reaching ±3.5 V into 1 kΩ. For single-supply video applications, level-shifting circuitry or AC-coupled inputs are required to maintain signal integrity within the usable output range. The device's rail-to-rail input stage is not implemented - THS4062CDRG4 is not a rail-to-rail op-amp.
How does the THS4062CDRG4 achieve 0.02% differential gain in video applications?
The THS4062CDRG4 achieves 0.02% differential gain via precision-matched transistor pairs in its dielectrically isolated complementary bipolar process, combined with optimized internal compensation that preserves amplitude linearity across the 4.43 MHz color subcarrier and harmonics. This is measured under NTSC 40 IRE modulation at G = 2 and ±15 V supply - a condition explicitly validated in the SLOS234E datasheet. THS4062CDRG4 maintains this performance without external trimming.
Is the THS4062CDRG4 pin-compatible with other devices in the THS406x family?
Yes, THS4062CDRG4 shares identical SOIC-8 pinout with THS4062CD, THS4062CDR, THS4062ID, and THS4062IDR - all follow the dual-amplifier layout shown in Figure 2 of SLOS234E. Pin functions (1OUT, 1IN−, 1IN+, −VCC, VCC+, 2OUT, 2IN−, 2IN+) are invariant across C- and I-suffix variants. No PCB redesign is required when upgrading from THS4062CD to THS4062CDRG4.
What decoupling is recommended for THS4062CDRG4 power pins?
Texas Instruments specifies a 0.1 µF ceramic capacitor placed <0.1 inch from each supply pin (VCC+ and −VCC), plus a shared 6.8 µF tantalum capacitor per rail - as shown in Figure 29 of SLOS234E. This dual-capacitor approach suppresses both high-frequency switching noise (>10 MHz) and low-frequency supply droop. Failure to implement this decoupling degrades PSRR (70–78 dB) and increases output distortion - verified in THS4062CDRG4 characterization tests.
