Product details
Overview
THS3202DGKR from Texas Instruments is a dual current-feedback amplifier (CFA) designed for high-frequency, low-distortion signal conditioning in demanding analog front-ends. It delivers 2 GHz unity-gain bandwidth, 9000 V/µs slew rate, ±115 mA output drive into 20 Ω, and operates from ±3.3 V to ±7.5 V (or 6.6–15 V single supply), making it suitable for RF/IF amplification, high-voltage ADC preamplification, and professional video line driving.
For engineers reviewing the THS3202DGKR datasheet, THS3202DGKR pinout, THS3202DGKR application, or THS3202DGKR equivalent, key selection criteria include large-signal bandwidth at 4 VPP (875 MHz @ ±5 V), differential gain error (0.008% NTSC), crosstalk (–60 dB @ 100 MHz), and thermal performance in the MSOP-8 PowerPAD™ package.
Technical Context
The THS3202DGKR implements a current-feedback architecture with high-impedance noninverting input (780 kΩ) and low-impedance inverting input (11 Ω), enabling stable wideband gain configurations up to G = +10. Its transimpedance gain (120–300 kΩ) and fast settling (19 ns to 0.1%) support precision high-speed closed-loop operation.
It features matched dual channels with <0.03° differential phase error (NTSC/PAL), low input voltage noise (1.65 nV/√Hz), and robust power-supply rejection (60–69 dB PSRR). The device maintains specified AC performance across –40°C to +85°C and supports thermally enhanced mounting via the exposed PowerPAD™ on the DGK package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 2 GHz - Enables stable gain-of-1 operation up to UHF frequencies without peaking or instability. |
| Slew Rate | 9000 V/µs - Supports clean 10-V step response with 0.45 ns rise/fall time and minimal slewing distortion. |
| Output Current Drive | ±115 mA into 20 Ω - Delivers high-current capability for driving low-impedance loads like 150-Ω video lines or ADC inputs. |
| Large-Signal Bandwidth | 875 MHz @ 4 VPP, ±5 V - Maintains flat frequency response for full-scale video or IF signals without roll-off. |
| Differential Gain/Phase Error | 0.008% / 0.03° (NTSC, G = +2, RL = 150 Ω) - Meets broadcast-grade video fidelity requirements. |
| Input Voltage Noise | 1.65 nV/√Hz (>10 MHz) - Minimizes added noise in wideband receiver chains and high-frequency sensor interfaces. |
| Crosstalk | –60 dB @ 100 MHz - Ensures channel isolation critical for dual-channel instrumentation and I/Q signal paths. |
Pinout & Package
The THS3202DGKR is housed in an 8-pin MSOP package with PowerPAD™ (exposed thermal pad on underside), requiring solder connection to a PCB ground plane for thermal management and optimal junction temperature control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1VIN+ | Noninverting input, Channel 1 | High-impedance (780 kΩ) node; sets input common-mode range (±2.6 V @ ±5 V supply). |
| 1VIN− | Inverting input, Channel 1 | Low-impedance (11 Ω) node; connects to feedback network for gain-setting and stability control. |
| 1VOUT | Output, Channel 1 | Capable of ±3.45 V swing into 100 Ω; drives heavy loads with <0.01 Ω closed-loop output impedance. |
| VS− | Negative supply rail | Accepts –3.3 V to –7.5 V; PSRR of 55–65 dB ensures immunity to negative rail noise. |
| VS+ | Positive supply rail | Accepts +3.3 V to +7.5 V; PSRR of 60–69 dB maintains signal integrity under supply ripple. |
| 2VIN− | Inverting input, Channel 2 | Electrically isolated from Channel 1; enables independent gain configuration per channel. |
| 2VIN+ | Noninverting input, Channel 2 | Matches Channel 1 specs; supports dual-path signal processing without inter-channel coupling. |
| 2VOUT | Output, Channel 2 | Identical performance to 1VOUT; crosstalk <–60 dB ensures independent high-fidelity output paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DGKR | Single-channel version; identical AC/DC specs, same MSOP-8 PowerPAD™ package footprint. | Used where only one high-speed amplifier channel is required-reduces board area and BOM count. | Select THS3201DGKR when dual-channel functionality is unnecessary and space/power optimization is prioritized. |
| THS3092DGKR | Lower bandwidth (220 MHz), lower slew rate (3000 V/µs), higher supply voltage range (±15 V), no PowerPAD™. | Better suited for high-voltage, lower-frequency applications (e.g., piezoelectric sensor excitation) where thermal density is less critical. | Choose THS3092DGKR for ±15 V systems needing >100 mA drive but not requiring GHz bandwidth or ultra-low distortion. |
Compared with THS3202DGKR, THS3201DGKR offers identical performance in half the channel count and package size, while THS3092DGKR trades bandwidth and thermal efficiency for higher supply tolerance and legacy ±15 V compatibility-neither is pin-compatible, but both serve adjacent high-current amplifier use cases.

FAQ
What is the maximum operating supply voltage for the THS3202DGKR?
The THS3202DGKR supports dual-supply operation from ±3.3 V to ±7.5 V (15 V total), or single-supply operation from 6.6 V to 15 V. Absolute maximum supply voltage is ±8.25 V (16.5 V total), beyond which permanent damage may occur. Operation at ±7.5 V enables full 2 GHz bandwidth and 1000 MHz large-signal response as verified in the datasheet.
Does the THS3202DGKR require external compensation components?
No, the THS3202DGKR is internally compensated for unity-gain stability and does not require external capacitors or resistors for basic operation. Its current-feedback architecture allows stable gain configurations from G = +1 to +10 using only standard feedback resistors (e.g., 402 Ω for G = +2), simplifying layout and reducing component count.
How does the PowerPAD™ on the THS3202DGKR improve thermal performance?
The exposed thermal pad on the THS3202DGKR's MSOP-8 PowerPAD™ package must be soldered to a PCB ground plane to achieve θJA = 54.2°C/W. This reduces junction-to-ambient thermal resistance by ~45% versus standard MSOP-8, enabling sustained ±115 mA output current at +85°C ambient without exceeding the 125°C reliability limit.
Can the THS3202DGKR drive a 50-Ω load directly?
Yes-the THS3202DGKR delivers ±115 mA into 20 Ω and maintains >±3.2 V output swing into 100 Ω. While not optimized for continuous 50-Ω termination, it can drive 50-Ω loads with appropriate series matching (e.g., 25 Ω in series) to preserve bandwidth and minimize reflections, as validated in TI's application notes for RF line driving.
What is the typical differential phase error of the THS3202DGKR in video applications?
The THS3202DGKR achieves a typical differential phase error of 0.03° under NTSC/PAL conditions (G = +2, RL = 150 Ω, TA = +25°C), meeting broadcast-grade video specifications. This value remains stable across temperature (±0.005° variation from –40°C to +85°C), ensuring consistent color timing in professional video infrastructure.
