Product details
Overview
THS4062IDG4 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, 40 ns settling time to 0.1%, ±11.5 V output swing into 250 Ω at ±15 V supplies, and 0.02% differential gain error-enabling broadcast-quality NTSC video line driving.
For engineers reviewing the THS4062IDG4 datasheet, THS4062IDG4 pinout, THS4062IDG4 application, or THS4062IDG4 equivalent, key selection criteria include dual-channel unity-gain stability, low distortion (−72 dBc THD at 1 MHz), wide supply range (±4.5 V to ±16 V), thermal performance in SOIC-8, and verified video-grade AC performance across −40°C to +85°C industrial temperature range.
Technical Context
The THS4062IDG4 employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture optimized for wideband stability at all gains in both inverting and noninverting configurations. Its internal compensation ensures unity-gain stability without external components while maintaining >70° phase margin.
It features matched dual amplifiers with 65 dB channel-to-channel crosstalk at 1 MHz, independent null pins per channel for offset trimming, and rail-to-rail input common-mode range (±13.8 V at ±15 V supplies). The device draws only 7.8 mA per channel quiescent current and supports single-supply operation from 9 V to 32 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 180 MHz at G = 1, ±15 V - enables baseband video and fast pulse amplification without roll-off |
| Slew rate | 400 V/µs at ±15 V - supports clean reproduction of fast-edged signals up to ~100 MHz |
| Settling time (0.1%) | 40 ns for 5-V step - meets timing-critical sampling and reconstruction in ADC/DAC interfaces |
| Differential gain error | 0.02% at NTSC 40 IRE, ±15 V - preserves color fidelity in professional analog video systems |
| Total harmonic distortion | −72 dBc at f = 1 MHz - ensures minimal spectral contamination in RF and IF signal chains |
| Supply voltage range | ±4.5 V to ±16 V dual or 9 V to 32 V single - accommodates legacy ±12 V, ±15 V, and modern 12 V/24 V industrial rails |
| Output drive | 115 mA per channel - drives 75 Ω video lines, multiple loads, or low-Z ADC inputs directly |
Pinout & Package
THS4062IDG4 is housed in an 8-pin SOIC (D) package with exposed pad thermal enhancement (PowerPAD™), rated for −40°C to +85°C operation. The package complies with JEDEC MS-012AC and supports standard surface-mount reflow profiles (Level-1-260°C-UNLIM).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel A output | High-current, low-impedance output node; requires series resistor ≥20 Ω when driving >10 pF capacitive load |
| 1IN− | Channel A inverting input | High-impedance node; trace length must be minimized to reduce parasitic capacitance and maintain stability |
| 1IN+ | Channel A noninverting input | High-impedance node; referenced to system ground or common-mode bias in single-supply designs |
| −VCC | Negative supply rail | Connects to negative power plane; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling |
| VCC+ | Positive supply rail | Connects to positive power plane; same decoupling as −VCC; PowerPAD must be soldered to thermal plane |
| 2OUT | Channel B output | Independent output; identical specs to 1OUT; crosstalk to Channel A is 65 dB at 1 MHz |
| 2IN− | Channel B inverting input | Matched to 1IN−; enables dual-path signal processing with consistent AC response |
| 2IN+ | Channel B noninverting input | Matched to 1IN+; supports synchronous dual-channel gain stages or differential receivers |

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 |
|---|---|---|---|
| THS4062IDGN | Same silicon, HVSSOP-8 (DGN) package with PowerPAD; 2.14 W thermal rating vs. SOIC-8's 740 mW at 25°C | Better thermal performance in space-constrained, high-power-density layouts; requires different footprint and reflow profile | Select THS4062IDGN when board area is limited and thermal dissipation >740 mW is required; not pin-compatible with SOIC-8 |
| THS4032ID | 100 MHz bandwidth, 250 V/µs slew rate, lower 5.5 mA/channel quiescent current; optimized for low-noise (10 nV/√Hz) rather than speed | Preferred for noise-sensitive, medium-bandwidth applications (e.g., audio preamps, sensor interfaces) where THS4062IDG4's speed is unnecessary | Choose THS4062IDG4 for >100 MHz signal paths; select THS4032ID only if bandwidth ≤100 MHz and noise <10 nV/√Hz is critical |
Compared with THS4062IDGN, THS4062IDG4 offers identical electrical performance but lower thermal capability in SOIC-8; versus THS4032ID, it trades 45% lower noise for 80% higher bandwidth and 60% faster slew rate-making it optimal for video and fast-pulse applications where speed dominates noise concerns.

FAQ
What is the operating temperature range for THS4062IDG4?
The THS4062IDG4 is specified for industrial operation from −40°C to +85°C. All key parameters-including bandwidth, slew rate, settling time, and distortion-are fully characterized and guaranteed across this range per the SLOS234E datasheet. This makes THS4062IDG4 suitable for deployment in factory automation, outdoor video enclosures, and industrial test equipment without derating.
Does THS4062IDG4 require external compensation for unity-gain stability?
No, THS4062IDG4 is internally compensated for unity-gain stability in both inverting and noninverting configurations. The device maintains >70° phase margin at G = 1 without external components. For optimal settling behavior with minimal ringing, TI recommends using a 270 Ω feedback resistor in noninverting unity-gain setups, as documented in Figure 27 of the THS4062IDG4 datasheet.
Can THS4062IDG4 drive 75 Ω video loads directly?
Yes, THS4062IDG4 can drive 75 Ω video loads directly. At ±15 V supplies, it delivers ±11.5 V output swing into 250 Ω and sustains 115 mA output current-sufficient for 75 Ω termination with gain = 2 (e.g., 1 Vpp in → 2 Vpp out). For optimal impedance matching and capacitive load isolation, place a 75 Ω series resistor at the output per Figure 28 in the THS4062IDG4 datasheet.
What is the purpose of Pins 1 and 8 (NULL) on THS4062IDG4?
Pins 1 and 8 on THS4062IDG4 are independent offset null terminals for Channel A and Channel B, respectively. Each connects to an internal resistive divider network; applying a potentiometer (e.g., 10 kΩ) between the NULL pin and the negative supply, with wiper grounded, allows fine adjustment of input offset voltage. This feature is retained from the THS4061 single-channel variant and supports precision DC-coupled applications.
Is THS4062IDG4 pin-compatible with other THS406x variants in SOIC-8?
Yes, THS4062IDG4 is pin-compatible with all THS4062 variants in SOIC-8 (D) package-including THS4062CD, THS4062ID, and THS4062IDR-as confirmed by the functional block diagram (Figure 2) and D-package pinout table in the SLOS234E datasheet. Pin assignments (1OUT, 1IN−, 1IN+, −VCC, VCC+, 2OUT, 2IN−, 2IN+) are identical across all SOIC-8 versions; only temperature grade and marking differ.
