Product details
Overview
THS4022IDGNR from Texas Instruments is a dual-channel, ultra-low-noise (1.2nV/√Hz), high-speed voltage-feedback operational amplifier optimized for gain ≥10V/V stable operation. It delivers 290MHz small-signal bandwidth, 470V/μs slew rate, and 30ns 0.1% settling time at G=10, enabling precision signal conditioning in ultrasound front-ends and source measurement units.
For engineers reviewing the THS4022IDGNR datasheet, THS4022IDGNR pinout, THS4022IDGNR application, or THS4022IDGNR equivalent, this page provides verified electrical specifications, HVSSOP-8 package layout, dual-amplifier channel isolation behavior, and validated alternatives for low-distortion, high-drive analog signal paths requiring ±4.5V to ±16V supply operation.
Technical Context
The THS4022IDGNR employs a voltage-feedback architecture with internal compensation optimized for minimum-phase stability at closed-loop gains of 10V/V and above. Its 2GHz gain-bandwidth product supports wideband applications while maintaining low group delay variation across its 290MHz –3dB bandwidth.
Each amplifier channel features independent high-current output stage capable of sourcing/sinking 200mA into low-impedance loads, with input-referred voltage noise of 1.2nV/√Hz and total harmonic distortion of –68dBc at 1MHz (RL = 150Ω), making it suitable for demanding imaging and metrology signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2 GHz - enables stable closed-loop operation up to 290 MHz at G = 10 V/V without external compensation |
| Slew rate | 470 V/μs - supports fast transient response for 10-V step signals within 30 ns (0.1% settling) |
| Input voltage noise | 1.2 nV/√Hz - critical for preserving SNR in low-level signal amplification (e.g., ultrasound receive paths) |
| Output drive current | 200 mA (typical) - drives 150Ω loads directly without external buffers in high-fidelity video or test equipment |
| Total harmonic distortion | –68 dBc @ 1 MHz, RL = 150Ω - ensures minimal spectral contamination in precision AC measurements |
| Supply voltage range | ±4.5 V to ±16 V - accommodates both industrial ±5V and high-dynamic-range ±15V systems |
| Channel-to-channel crosstalk | –54 dBc @ 1 MHz - maintains signal integrity in dual-channel differential or interleaved architectures |
Pinout & Package
THS4022IDGNR is housed in an 8-pin HVSSOP (DGN) package with exposed thermal pad, optimized for high-frequency PCB layout and thermal dissipation (RθJA = 52°C/W). The dual-amplifier configuration shares power rails and requires separate input/output routing per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-current output node for first amplifier; requires local decoupling and controlled-impedance trace routing |
| 1IN– | Channel 1 inverting input | Differential input pair node; sensitive to parasitic capacitance-keep trace short and symmetric |
| 1IN+ | Channel 1 noninverting input | Reference-side input; matched impedance required to minimize CMRR degradation |
| VCC– | Negative power supply | Common return for both amplifiers; connect to low-inductance ground plane via multiple vias |
| 2IN+ | Channel 2 noninverting input | Independent second channel input; isolate from Channel 1 traces to maintain –54 dBc crosstalk |
| 2IN– | Channel 2 inverting input | Second differential input; mirror layout of Channel 1 for consistent AC performance |
| 2OUT | Channel 2 output | Second high-drive output; route separately to avoid coupling into 1OUT or supply lines |
| VCC+ | Positive power supply | Shared rail for both channels; bypass with 100nF ceramic + 10μF tantalum near package |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low voltage noise | 1.2 nV/√Hz enables sub-microvolt signal amplification without degrading system SNR in medical imaging |
| Stable at G ≥ 10 V/V | No external compensation required for gain-of-10 configurations-reduces BOM count and layout complexity |
| High slew rate & bandwidth | 470 V/μs + 290 MHz BW supports >100 MSPS sampling in active filter and driver stages |
| High output current drive | 200 mA capability eliminates need for discrete output buffers in 150Ω video or test load interfaces |
| Low THD at high frequency | –68 dBc @ 1 MHz ensures accurate waveform reproduction in SMU and power quality metering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Lower noise (0.94nV/√Hz) but lower slew rate (280 V/μs); single-channel only; requires external compensation below G = 25 | Better for ultra-low-noise DC-coupled preamps; unsuitable for fast settling or dual-channel synchronous use | Select when absolute lowest noise dominates over speed and channel count requirements |
| ADA4898-2ARZ | Higher precision (0.1mV VOS, 1.1nV/√Hz) but lower bandwidth (65MHz GBW); rail-to-rail output; ±3V to ±12V supply | Preferred for battery-powered portable instrumentation; not viable for ±15V high-swing systems | Choose for precision low-power applications where 290MHz bandwidth is unnecessary |
Compared with THS4022IDGNR, LMH6629MA/NOPB offers superior noise floor but sacrifices slew rate and channel integration, while ADA4898-2ARZ trades bandwidth for precision and supply flexibility-neither matches THS4022IDGNR's combination of dual-channel, 290MHz, ±16V, and 1.2nV/√Hz in one HVSSOP package.

FAQ
What is the minimum stable gain for THS4022IDGNR?
The THS4022IDGNR is internally compensated for unity-gain unstable operation and is specified as stable at closed-loop gains ≥10 V/V. Attempting to use it at gains below 10 V/V requires external compensation networks to prevent peaking or oscillation. This design choice prioritizes bandwidth and slew rate over low-gain versatility.
Does THS4022IDGNR support single-supply operation?
Yes, THS4022IDGNR supports single-supply operation from 9 V to 33 V. Its input common-mode range extends to within 1.2 V of the negative rail and 1.7 V of the positive rail (at ±5 V), enabling true single-supply configurations with proper level-shifting on inputs and outputs.
What is the thermal resistance (RθJA) of THS4022IDGNR in its HVSSOP-8 package?
The THS4022IDGNR in the DGN (HVSSOP-8) package has a junction-to-ambient thermal resistance (RθJA) of 52°C/W under standard JEDEC JESD51-7 conditions. This value assumes a 2-layer board with 1-in² copper pour; actual thermal performance improves significantly with enhanced PCB copper area and thermal vias to inner ground planes.
How does THS4022IDGNR handle channel-to-channel crosstalk?
THS4022IDGNR specifies –54 dBc channel-to-channel crosstalk at 1 MHz, measured with one channel driven and the other monitored open-circuit. This performance results from isolated internal die routing and shared supply rejection-critical for dual-channel synchronous sampling where inter-channel leakage must be minimized.
Can THS4022IDGNR drive a 50Ω load directly?
THS4022IDGNR can drive 50Ω loads continuously only at reduced output swing (±3.5 V max at ±5 V supplies) and elevated junction temperature. For full ±12.9 V swing into 250Ω, derating is required; sustained 50Ω operation demands careful thermal design and may necessitate external current boosting in high-duty-cycle applications.
