Product details
Overview
THS4082ID from Texas Instruments is a dual-channel, ultralow-power, high-speed voltage-feedback operational amplifier designed for precision video and communication signal conditioning. It delivers 175 MHz bandwidth (−3 dB, G = 1), 230 V/µs slew rate, and 43 ns settling time (0.1%), operating at just 3.4 mA per channel quiescent current on ±5 V to ±15 V supplies - enabling low-power HD video driver and ADC buffer applications.
For engineers reviewing the THS4082ID datasheet, THS4082ID pinout, THS4082ID application, or THS4082ID equivalent, key selection criteria include dual-channel video gain flatness (35 MHz, 0.1 dB), differential phase error (0.05°), channel-to-channel crosstalk (−75 dB), and thermal performance in the PowerPAD™ DGN package for high-density analog layouts.
Technical Context
The THS4082ID employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture optimized for wide bandwidth and fast transient response. Its internal compensation targets maximum small-signal speed while maintaining stability into 150 Ω loads.
It supports dual-supply (±5 V to ±15 V) and single-supply (10 V to 30 V) operation, with rail-to-rail output swing (±13.6 V @ ±15 V, RL = 250 Ω) and robust input common-mode range (±14.1 V @ ±15 V). Channel isolation is maintained via dedicated VCC+ and VCC− pins per amplifier section.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (−3 dB) | 175 MHz at ±15 V, G = 1 - enables baseband video and IF signal amplification up to 1080p60 without roll-off |
| Slew Rate | 230 V/µs at ±15 V - supports clean 5-V step response in <43 ns for fast data acquisition front-ends |
| Differential Phase Error | 0.05° at NTSC, ±15 V - preserves color fidelity in broadcast-quality analog video transmission |
| THD | −64 dBc @ 1 MHz, RL = 150 Ω - ensures minimal harmonic contamination in composite video and DAC output stages |
| Quiescent Current | 3.4 mA per channel @ ±15 V - allows dual-channel operation under 7 mA total, critical for thermally constrained enclosures |
| Crosstalk | −75 dB @ 1 MHz - prevents inter-channel interference in dual ADC drivers or stereo video paths |
| Operating Temp Range | −40°C to +85°C (I-suffix) - qualified for industrial video surveillance and automotive display systems |
Pinout & Package
The THS4082ID is available in the thermally enhanced MSOP PowerPAD™ (DGN) package - an 8-pin surface-mount device with exposed thermal pad on underside, electrically isolated from all terminals. This package reduces θJA to 58.4°C/W and supports 2.14 W power dissipation at TA = 25°C when properly soldered to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier 1 output | High-current (85 mA typ) buffered signal path; requires series resistor ≥20 Ω for >10 pF capacitive loads |
| 1IN− | Inverting input, Amp 1 | High-impedance node; trace length must be minimized to reduce parasitic capacitance and maintain phase margin |
| 1IN+ | Non-inverting input, Amp 1 | Accepts DC-coupled or AC-coupled signals; common-mode range extends to ±14.1 V @ ±15 V supply |
| VCC− | Negative supply rail | Shared negative rail for both amplifiers; decoupling capacitor (0.1 µF ceramic + 6.8 µF tantalum) required adjacent to pin |
| VCC+ | Positive supply rail | Shared positive rail for both amplifiers; independent from VCC− to enable split-supply operation |
| 2OUT | Amplifier 2 output | Independent output stage; layout symmetry with 1OUT recommended to minimize coupling |
| 2IN− | Inverting input, Amp 2 | Electrically isolated from 1IN−; crosstalk −75 dB ensures minimal inter-channel feedthrough |
| 2IN+ | Non-inverting input, Amp 2 | Matches 1IN+ specs; supports identical gain configurations for dual-path signal chains |
Key Features

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 |
|---|---|---|---|
| THS4082CDGN | Same silicon, C-suffix (0°C to 70°C) rating; identical electrical specs and DGN package | Limited to commercial-temperature systems; not rated for extended industrial ambient | Select THS4082CDGN only for cost-sensitive consumer or lab equipment with controlled environment |
| LMH6702MA | Higher 1.8 GHz GBW but 12.5 mA/ch quiescent current; no PowerPAD™ package; SOIC-8 only | Optimized for RF IF gain blocks, not video; lacks differential phase/gain specs for analog video compliance | Choose LMH6702MA for wideband RF signal chains where power efficiency and video linearity are secondary |
Compared with THS4082CDGN, the THS4082ID offers guaranteed −40°C startup and 85°C sustained operation - essential for outdoor video enclosures and factory-floor controllers. Versus LMH6702MA, it trades raw bandwidth for 3.7× lower quiescent power and verified video distortion metrics, making it the only option meeting SMPTE analog video fidelity requirements in dual-channel form.

FAQ
What is the maximum output current capability of the THS4082ID?
The THS4082ID delivers 85 mA typical continuous output current per channel into 20 Ω loads at ±15 V supply, with short-circuit current of 100 mA. This enables direct driving of 75 Ω video lines or multiple parallel ADC inputs without external buffers - a key design advantage over general-purpose op-amps limited to 20–40 mA.
Does the THS4082ID support single-supply operation?
Yes, the THS4082ID operates from a single supply of 10 V to 30 V, in addition to dual supplies of ±5 V to ±15 V. Its input common-mode range extends to within 1.2 V of the negative rail and output swings to within 1.4 V of each rail - allowing true single-supply use in 12 V or 24 V industrial systems with proper level-shifting design.
How does the PowerPAD™ DGN package improve thermal performance of the THS4082ID?
The THS4082ID in DGN package features an exposed thermal pad electrically isolated from all pins. When soldered to ≥68 mil × 70 mil PCB copper area with five 13-mil vias connected to an internal ground plane, it achieves θJA = 58.4°C/W - reducing junction temperature rise by >70% versus standard MSOP, enabling full 85 mA output drive at 85°C ambient.
What video standards does the THS4082ID meet for differential gain and phase?
The THS4082ID meets SMPTE 253M broadcast video specifications with 0.01% differential gain error and 0.05° differential phase error at NTSC, ±15 V supply. These values are measured under standardized 40 IRE modulation conditions and confirm suitability for professional analog video routing, broadcast equipment, and medical imaging displays.
Can the THS4082ID drive capacitive loads without oscillation?
The THS4082ID is internally compensated for resistive loads but requires external isolation for capacitive loads >10 pF. A series resistor of ≥20 Ω placed directly at the output pin suppresses high-frequency ringing - for example, a 75 Ω resistor provides both load isolation and source-end impedance matching in 75 Ω video systems.
