Texas Instruments THS3062DDA

Overview

THS3062DDA from Texas Instruments is a dual-channel, high-voltage, current-feedback amplifier optimized for low-distortion, high-slew-rate signal conditioning in video, line driver, and high-speed ADC preamplifier applications. It delivers 7000 V/μs slew rate at ±15 V supplies, 300 MHz unity-gain bandwidth, –81 dBc third-harmonic distortion at 10 MHz (G = 2), ±145 mA output drive into 50 Ω, and operates across ±5 V to ±15 V supply range.

For engineers reviewing the THS3062DDA datasheet, THS3062DDA pinout, THS3062DDA application, or THS3062DDA equivalent, key selection criteria include its current-feedback architecture enabling stable high-gain bandwidth (220 MHz at G = 10), PowerPAD-enhanced SOIC-8 thermal performance, and verified differential gain/phase accuracy (<0.02% / <0.01°) for NTSC/PAL video systems.

Technical Context

The THS3062DDA uses Texas Instruments' BiCOM-I dielectrically isolated complementary bipolar process, supporting true current-feedback operation with transimpedance gain >0.6 MΩ and input resistance of 518 kΩ (noninverting) and 71 Ω (inverting). Its bandwidth scales inversely with feedback resistor value-e.g., 220 MHz at G = 10 with R_f = 200 Ω-and maintains <0.3 dB peaking in unity gain.

Thermal design is critical: the DDA package features θ_JA = 45.8°C/W and requires soldering the PowerPAD to a thermally conductive PCB plane. At ±15 V, quiescent current is 8.3 mA per channel, rising to 12 mA max over temperature; output swing reaches ±13.3 V into 150 Ω with 145 mA sourcing/sinking capability.

Key Specifications

Pinout & Package

The THS3062DDA is housed in an 8-pin SOIC package with PowerPAD™ thermally enhanced bottom pad (electrically isolated), requiring PCB copper pour connection for safe thermal dissipation up to 2.18 W at T_A ≤ +25°C.

FAQ

What is the maximum safe operating voltage for THS3062DDA?

The THS3062DDA has an absolute maximum supply voltage rating of ±16.5 V per rail. However, its specified operating range is ±5 V to ±15 V, and all published AC/DC performance data-including 7000 V/μs slew rate and –81 dBc HD3-are guaranteed only within that range. Operating at ±16.5 V may exceed internal junction temperature limits unless thermal design strictly follows TI's PowerPAD mounting guidelines.

Does THS3062DDA require external compensation components?

No, the THS3062DDA is internally compensated for unity-gain stability and does not require external compensation capacitors. Its current-feedback architecture achieves <0.3 dB peaking in unity gain without added components. However, feedback resistor selection (e.g., 750 Ω for G = 1, 560 Ω for G = 2) is critical to maintain phase margin and bandwidth-see Table 1 in the THS3062DDA datasheet for recommended values.

Can THS3062DDA drive a 75-Ω video load directly?

Yes, the THS3062DDA can drive a 75-Ω load directly with full performance: at ±15 V supply, it delivers ±13.0 V output swing and ±145 mA current into 150 Ω, which extrapolates to >±10 V into 75 Ω. For optimal video fidelity, use a series 75-Ω termination at the output and match source impedance-verified by THS3062DDA's 0.02% differential gain and 0.01° phase error under 150-Ω load conditions.

How does THS3062DDA's PowerPAD package differ from standard SOIC?

The THS3062DDA's SOIC-8 PowerPAD package integrates an electrically isolated copper thermal pad on the underside, soldered directly to a large PCB copper pour. This reduces θ_JA to 45.8°C/W-nearly half that of standard SOIC (97.5°C/W)-enabling 2.18 W power dissipation at T_A ≤ +25°C. Failure to connect the PowerPAD results in thermal runaway and permanent damage, as confirmed in TI's SLMA002 technical brief.

Is THS3062DDA suitable for single-supply operation?

The THS3062DDA is specified for dual-supply operation (±5 V to ±15 V) and is not characterized for true single-supply use. While it can operate with a 10–30 V single supply (e.g., +15 V and ground), input common-mode range is limited to ±3.1 V at ±5 V supply and ±13.1 V at ±15 V-requiring level-shifting circuitry for ground-referenced inputs. TI recommends dual supplies for full parameter compliance and optimal distortion performance in THS3062DDA applications.
