Product details
Overview
THS3110CD from Texas Instruments is a low-noise, high-voltage current-feedback operational amplifier optimized for video distribution and high-speed analog signal conditioning. It delivers 90 MHz small-signal bandwidth (G = 2, RL = 100 Ω), 1300 V/μs slew rate, ±15 V supply operation, 260 mA output drive, and <0.013% differential gain error with PAL/NTSC video loads. It is used in broadcast-grade video routing systems requiring multi-load drive capability.
For engineers reviewing the THS3110CD datasheet, THS3110CD pinout, THS3110CD application, or THS3110CD equivalent, this page provides verified technical context, package mapping, real-world video performance data, power-down timing behavior, and validated alternative options for video amplification and capacitive load driving.
Technical Context
The THS3110CD employs a current-feedback architecture with separate high-impedance noninverting input (41 MΩ) and low-impedance inverting input, enabling wide bandwidth independent of closed-loop gain. Its transimpedance gain of 1 MΩ supports stable operation with reactive feedback networks.
It integrates a dedicated power-down pin (PD) that reduces quiescent current from 4.8 mA to 270 μA while maintaining defined REF voltage range (VS– to VS+ – 4 V) and fast 4 μs turn-on delay. The SOIC-8 package includes PowerPAD™ thermal enhancement for sustained 260 mA output into 25 Ω loads at ±15 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 90 MHz at G = 2, RL = 100 Ω - enables full HD video bandwidth with margin |
| Slew rate | 1300 V/μs at G = 2, RL = 100 Ω - supports 8-VPP output steps without distortion |
| Differential gain | 0.013% (PAL), 0.011% (NTSC) - meets broadcast video fidelity requirements |
| Output current | ±260 mA min into 25 Ω - drives up to eight 150 Ω video loads simultaneously |
| Input voltage noise | 3 nV/√Hz - preserves SNR in low-level analog signal paths |
| Power-down current | 270 μA max - reduces system standby power in multi-channel video routers |
| Supply range | ±5 V to ±15 V - compatible with legacy analog video rails and modern dual-rail supplies |
Pinout & Package
THS3110CD is housed in an 8-pin SOIC (D) package with exposed PowerPAD™ thermal pad on underside. Pin 1 is NC; pins 2 (VIN−), 3 (VIN+), 4 (VS−), 6 (VS+), 7 (VOUT), and 8 (NC) are functional; pin 5 is PD (power-down control).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | No internal connection | Unused pins; must be left floating or grounded per layout guidelines |
| 2 | Inverting input | Low-impedance node for feedback network; sets closed-loop gain with RF |
| 3 | Noninverting input | High-impedance (41 MΩ) input for signal source; minimal loading on source |
| 4 | Negative supply | Connects to −15 V rail; supports rail-to-rail input common-mode down to −13.3 V |
| 6 | Positive supply | Connects to +15 V rail; supports rail-to-rail input common-mode up to +13.3 V |
| 7 | Output | Capable of ±13.4 V swing into 100 Ω; drives 75 Ω transmission lines directly |
Key Features
| Feature | Design Value |
|---|---|
| Power-down function | Reduces quiescent current to 270 μA with 4 μs turn-on delay - enables dynamic channel gating in video switchers |
| Current-feedback topology | 90 MHz bandwidth maintained across gains 1–10 - eliminates gain-bandwidth trade-off in multi-gain video stages |
| 75 Ω line drive capability | Optimized output stage delivers <0.033° differential phase error into 150 Ω loads - preserves color fidelity across multiple video taps |
| Low input current noise | 2 pA/√Hz (noninverting), 10 pA/√Hz (inverting) - minimizes Johnson noise contribution in high-Z sensor interfaces |
| Thermal-enhanced SOIC | PowerPAD™ reduces θJA to 95°C/W - sustains 260 mA continuous output at +70°C ambient |
Applications
| Broadcast Video Distribution | High-Speed Capacitive Load Driver |
|---|---|
|

IC Role / Device Role / Timing Role: High-slew-rate gate driver delivering ±12 V to 1000 pF gate capacitance. Use Value: Sustains 1300 V/μs slew into capacitive load - reduces switching losses by minimizing gate transition time. |
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 |
|---|---|---|---|
| THS3111CD | No power-down pin; identical AC/DC specs and SOIC-8 packaging | Used where always-on operation is required; lacks dynamic power gating | Select THS3111CD when system-level power sequencing eliminates need for per-amplifier shutdown |
| LMH6702MA | Higher 1.7 GHz GBW but lower 120 mA output drive; SOIC-8, no PowerPAD | Better for RF IF amplification; insufficient for multi-load video drive | Choose LMH6702MA only for wideband signal chain stages requiring >500 MHz bandwidth and <100 mA load |
Compared with THS3111CD and LMH6702MA, THS3110CD uniquely combines multi-load video drive capability, integrated power-down, and thermal-enhanced SOIC packaging - making it the only option among the three qualified for broadcast-grade video distribution with active power management.

FAQ
What is the maximum number of 150 Ω video loads the THS3110CD can drive while maintaining broadcast video specifications?
The THS3110CD maintains differential gain error <0.03% and differential phase error <0.04° when driving up to eight 150 Ω loads simultaneously under ±15 V supply conditions with gain = 2 and RF = 1 kΩ. This is confirmed by Figure 29 and Figure 30 in the official SLOS422E datasheet, which show worst-case PAL/NTSC performance across 0–8 loads.
Does the THS3110CD require external compensation for stability with capacitive loads?
Yes - the THS3110CD requires series isolation resistor (RISO) in the feedback path when driving >10 pF capacitive loads. Figure 8 in the datasheet specifies RISO = 54.9 Ω for 22 pF, 39.2 Ω for 47 pF, and 28 Ω for 100 pF. Omitting RISO causes peaking and potential oscillation due to phase margin degradation.
What is the actual power-down behavior of the THS3110CD when the PD pin is left unconnected?
When the PD pin is left unconnected, the THS3110CD defaults to enabled (ON) state per datasheet Note: "The device with the power-down option defaults to the ON state if no signal is applied to the PD pin." No pull-up or pull-down is required for normal operation; PD must be actively driven ≥(REF + 2 V) to enter power-down mode.
Can the THS3110CD operate from a single +30 V supply instead of dual ±15 V rails?
Yes - the THS3110CD supports single-supply operation from +10 V to +30 V as specified in the Recommended Operating Conditions table. At +30 V, the input common-mode range extends from 2.5 V to 27.5 V, and output swing reaches ±13.4 V into 100 Ω, enabling true single-rail high-voltage analog signal processing.
How does the PowerPAD™ thermal pad on the THS3110CD SOIC-8 package affect PCB layout requirements?
The PowerPAD™ must be soldered to a minimum 3-inch × 3-inch copper pour using ≥6 thermal vias (0.3 mm diameter) to achieve the rated θJA = 95°C/W. Without proper thermal connection, junction temperature exceeds safe limits under 260 mA load, risking parametric drift or failure - per TI Technical Brief SLMA002.
