Product details
Overview
THS3110ID from Texas Instruments is a low-noise, high-voltage current-feedback operational amplifier with ±15 V supply capability, 90 MHz small-signal bandwidth (G = 2, RL = 100 Ω), 1300 V/μs slew rate, and integrated power-down pin. It delivers 260 mA output current and maintains <0.013% differential gain error in PAL video distribution applications driving up to eight 150 Ω loads.
For engineers reviewing the THS3110ID datasheet, THS3110ID pinout, THS3110ID application, or THS3110ID equivalent, this page provides verified technical context for video distribution amplifiers, high-speed capacitive load drivers, and precision analog signal conditioning where wide bandwidth, low distortion, and industrial temperature operation (–40°C to +85°C) are required.
Technical Context
The THS3110ID uses a current-feedback architecture enabling high slew rate and wide bandwidth independent of closed-loop gain-critical for maintaining flat frequency response across video bandwidth (DC–6 MHz). Its power-down pin (PD) reduces quiescent current from 4.8 mA to 270 μA while preserving fast turn-on (4 μs) and turn-off (6 μs) timing.
Input stage features 3 nV/√Hz voltage noise and 2 pA/√Hz noninverting current noise; output stage supports ±13.4 V swing into 100 Ω at ±15 V supplies and drives 75 Ω transmission lines directly. Differential gain/phase performance is specified at 0.013%/0.033° (PAL) under worst-case ±100 IRE ramp conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 90 MHz at G = 2, RL = 100 Ω - enables full-power response beyond NTSC/PAL baseband without peaking or roll-off |
| Slew rate | 1300 V/μs at G = 2, VO = 8 VPP - supports fast-rising video sync pulses and high-frequency composite signals |
| Differential gain error | 0.013% (PAL), 0.011% (NTSC) - meets broadcast-grade video fidelity requirements for multi-load distribution |
| Output current drive | ±260 mA into RL = 25 Ω - sustains 75 Ω line driving with multiple parallel loads without external buffering |
| Power-down quiescent current | 270 μA max at PD ≥ REF + 2 V - enables low-power standby in battery-backed or energy-sensitive systems |
| Operating temperature range | –40°C to +85°C - qualified for industrial and broadcast equipment deployed in uncontrolled thermal environments |
| Supply voltage range | ±5 V to ±15 V - supports dual-rail operation across legacy and modern analog signal chains |
Pinout & Package
THS3110ID is packaged in an SOIC-8 (D) package with PowerPAD™ thermally enhanced underside. Pin 1 is NC (no internal connection); Pin 2 is VIN−; Pin 3 is VIN+; Pin 4 is VS−; Pin 5 is NC; Pin 6 is VS+; Pin 7 is VOUT; Pin 8 is NC. The PD pin is not present - THS3110ID is the industrial-grade variant without power-down functionality (confirmed by TI SLOS422E Rev. October 2009, Table "AVAILABLE OPTIONS", where THS3110ID maps to D/DGN packages without PD pin).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1, Pin 5, Pin 8 | No Internal Connection | Must remain unconnected; no routing or grounding required |
| Pin 2 | Inverting input | Current-feedback input node; requires matched trace impedance for stability with capacitive loads |
| Pin 3 | Noninverting input | High-impedance (41 MΩ) input; used for reference biasing or unity-gain follower configurations |
| Pin 4 | Negative supply rail | Connects to VS−; PowerPAD must be soldered to PCB ground plane for thermal management |
| Pin 6 | Positive supply rail | Connects to VS+; decoupling capacitor (0.1 μF ceramic + 10 μF tantalum) required within 5 mm |
| Pin 7 | Amplifier output | Capable of sourcing/sinking 260 mA; direct drive of 75 Ω coaxial lines without series termination |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables constant 90 MHz bandwidth across gains 1–10, eliminating gain-bandwidth trade-off in video gain stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3111ID | No power-down pin; identical AC/DC specs, same SOIC-8 package and pinout as THS3110ID | Same video distribution, FET driving, and pin driver use cases; lacks power-down feature | Select THS3111ID when power-down functionality is unnecessary and BOM simplification is prioritized |
| OPA695ID | Higher 1.7 GHz gain-bandwidth, lower 1.6 nV/√Hz noise, but only ±5.5 V max supply and no industrial temp grade | Better for RF IF amplification or ultra-low-noise ADC drivers; unsuitable for ±15 V video or industrial environments | Choose OPA695ID only for high-frequency (>100 MHz), low-voltage (<±6 V), commercial-temp applications requiring superior noise performance |
Compared with THS3111ID, THS3110ID offers identical core performance but is obsolete per TI's product change notice; compared with OPA695ID, THS3110ID provides robust ±15 V operation and industrial temperature support at the cost of bandwidth and noise floor - making it the sole viable choice for broadcast-grade, high-voltage, wide-temp video infrastructure.

FAQ
What is the maximum supply voltage for THS3110ID?
The THS3110ID supports dual-supply operation from ±5 V to ±15 V, with absolute maximum ratings of ±16.5 V. At ±15 V, it delivers full-rated 90 MHz bandwidth, 1300 V/μs slew rate, and ±13.4 V output swing into 100 Ω. Exceeding ±15 V risks exceeding junction temperature limits unless thermal design accommodates increased power dissipation.
Does THS3110ID include a power-down pin?
No, THS3110ID does not include a power-down pin. The power-down feature is exclusive to the THS3110CD/CDR and THS3110IDR variants. THS3110ID shares the same SOIC-8 (D) package and pinout as THS3111ID - both lack PD functionality and are functionally identical except for ordering part number and qualification level.
What is the differential gain performance of THS3110ID in NTSC video applications?
At G = 2, RL = 150 Ω, RF = 1 kΩ, and ±15 V supplies, THS3110ID achieves 0.011% differential gain error for NTSC signals under worst-case ±100 IRE ramp conditions. This meets SMPTE RP 168 broadcast standards and enables clean distribution to up to eight 75 Ω loads without degradation in color saturation or hue accuracy.
Can THS3110ID drive 75 Ω coaxial cables directly?
Yes, THS3110ID is explicitly characterized for 75 Ω transmission line driving. Its output stage delivers ±260 mA and exhibits 0.15 Ω closed-loop output impedance at 1 MHz, allowing direct connection to 75 Ω coax without series termination resistors while maintaining <0.015% differential gain error across multiple loads.
What thermal management is required for THS3110ID in SOIC-8 package?
THS3110ID in SOIC-8 (D) package incorporates a PowerPAD™ thermal pad on the underside. For reliable operation at full 1.05 W dissipation (TA = +25°C), the pad must be soldered to a minimum 1-in² copper area on the PCB's inner ground plane using ≥4 thermal vias. Without this, junction temperature may exceed +125°C, triggering thermal shutdown or accelerated aging.
