Typical Applications
THS4062IDGNR is suitable for 6 applications: Video Line Driving and Distribution, Communication Line Drivers (ADSL/VDSL), High-Speed ADC Input Buffering, Imaging and Ultrasound Front Ends, Test and Measurement Signal Chains, Active Filters and Wideband Gain Blocks.
Video Line Driving and Distribution
The THS4062IDGNR fits video line driving because its 0.02% differential gain and 0.02-degree differential phase errors are below NTSC/PAL visibility thresholds, while 75 MHz of 0.1 dB flatness preserves pulse fidelity across the video band. The 115 mA typical output drive lets each channel directly back-terminate a 75-ohm coaxial cable with a series resistor in gain-of-2 configuration, absorbing reflections and delivering a clean signal to the far end. Because both channels share one die, channel-to-channel gain and phase track closely, which matters in RGB and multi-drop distribution amplifiers. The 180 MHz bandwidth leaves ample margin above the 6-8 MHz video baseband, keeping transient response sharp with minimal overshoot on standard test patterns.

Communication Line Drivers (ADSL/VDSL)
In xDSL and wired-communication line drivers, the THS4062IDGNR provides the combination of bandwidth, slew rate, and output current that transformer-coupled line interfaces demand. The 400 V/us slew rate supports high peak-to-average ratio discrete-multitone waveforms without slew-induced distortion, and 115 mA of drive handles the stepped-up current through the line transformer primary. Very low distortion preserves constellation accuracy and reduces adjacent-channel emissions, while the 180 MHz bandwidth covers wideband upstream and downstream spectra. The dual-channel format lets one device drive a differential pair of amplifiers per line, halving device count. Designers should verify transformer saturation and thermal dissipation at worst-case crest factors, using the exposed pad pour to conduct heat away from the die.
Recommended
High-Speed ADC Input Buffering
When driving high-speed ADCs, the THS4062IDGNR offers 40 ns settling to 0.1% and 180 MHz bandwidth, giving the amplifier enough closed-loop speed to charge the ADC's switched-capacitor input between conversion cycles. The 115 mA output drive absorbs the dynamic charge-injection currents of the ADC sample-and-hold without significant voltage disturbance, and the low distortion keeps harmonics below the converter's quantization floor in 8-to-10-bit systems. In dual-channel digitizer boards, both buffer channels come from one die, so gain and offset track with temperature, improving interleaved or simultaneous-sampling accuracy. A small series resistor (typically 10 to 25 ohms) between amplifier output and ADC input, plus a shunt capacitor at the pin, damps switching kickback per TI ADC interface application guidance.
Recommended
Imaging and Ultrasound Front Ends
Medical and industrial imaging receivers use arrays of closely matched, wideband gain stages, and the THS4062IDGNR addresses this with two matched amplifiers per 8-pin package, maximizing channel density on multilayer boards. Its 180 MHz bandwidth covers typical ultrasonic transducer harmonic content after filtering, and the 400 V/us slew rate handles the fast leading edge of received echoes without slewing distortion. Low differential gain and phase performance translates to low amplitude and phase ripple across the received band, protecting grayscale fidelity and Doppler accuracy. The 115 mA output capability drives ADC buffers, cable drivers, or active filters downstream. Channel tracking across one die reduces inter-channel mismatch, which is critical for beamforming algorithms that sum many channels with precise phase relationships.
Recommended
Test and Measurement Signal Chains
Bench instruments, arbitrary waveform generator outputs, and scope front-end gain stages benefit from the THS4062IDGNR's combination of 180 MHz bandwidth, 40 ns settling, and high 115 mA output drive. Settling time to 0.1% in 40 ns supports fast pulse and step reproduction with predictable accuracy windows, while low distortion preserves spectral purity for generator outputs feeding filters or analyzers. The wide 9 V to 33 V supply range accommodates +/-12 V or +/-15 V rails common in instrument analog sections, enabling large output swings into 50-ohm back-terminated loads. The dual format is convenient for differential-to-single-ended and single-ended-to-differential converter stages within the same package. Designers should budget thermal dissipation for sustained high-current operation using adequate exposed-pad copper.
Recommended
Active Filters and Wideband Gain Blocks
The constant gain-bandwidth behavior of a voltage-feedback amplifier makes the THS4062IDGNR predictable in Sallen-Key, multiple-feedback, and impedance-conversion filter topologies up to tens of megahertz. With 180 MHz of bandwidth, Q enhancement and corner-frequency shift remain small even for 20-50 MHz filters, and the 400 V/us slew rate prevents slew limiting on large sinusoids near the corner frequency. Each dual package implements two filter sections or a differential biquad, compactly scaling to higher-order responses. The 70 dB open-loop gain keeps passband gain accuracy in closed-loop gains up to roughly 10. Layout practitioners should keep feedback paths short, use ground-plane-guarded summing nodes, and verify phase margin with the actual source and load impedances of the filter network.

Key Differentiators
- 180 MHz bandwidth in a dual package (vs THS4032IDGN)
- 115 mA output drive per channel (vs THS4032IDGN)
- Video-grade distortion specification (vs THS4032IDGN)
Design Notes
The exposed pad on the bottom of the DGN package is connected to V- and must be soldered to a copper pour. At 180 MHz, the pad also serves as the main low-inductance return path; a floating or poorly wetted pad causes gain peaking, ringing on pulses, and elevated die temperature. Use an array of thermal vias (typically 4-9) from the pad footprint to internal ground/power planes, and verify reflow coverage with X-ray on first-article boards.
Bypass V+ (pin 8) and V- (pin 4) each with 0.1 uF ceramic capacitors placed within 2-3 mm of the pins, plus 4.7-10 uF bulk capacitance per supply rail. At 400 V/us slew rate, load currents transients are fast; long bypass loops cause supply-coupled ringing. Estimated: a 115 mA step into a 50-ohm load with 10 nH of loop inductance produces a ~1.15 V supply disturbance if decoupling is distant - keep loops small.
Do not drive purely capacitive loads directly: the THS4062 needs an isolation resistor (typically 10-50 ohms) for cable/long-line capacitance to preserve phase margin. Keep feedback resistors in the 500 ohm to 1 kohm range - too large adds parasitic-capacitance peaking, too small loads the output. In gain-of-1 configurations, use the datasheet-recommended compensation approach, since unity-gain is the worst-case phase-margin condition for voltage-feedback amplifiers.
