Product details
Overview
THS4022IDRG4 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 THS4022IDRG4 datasheet, THS4022IDRG4 pinout, THS4022IDRG4 application, or THS4022IDRG4 equivalent, key selection criteria include its dual-channel HVSSOP-8 package, ±4.5V to ±16V dual-supply support, 200mA output drive capability, –68dBc THD at 1MHz, and guaranteed stability at gains ≥10V/V without external compensation.
Technical Context
The THS4022IDRG4 employs a voltage-feedback architecture with fully differential input stage and high-current output stage, enabling wide closed-loop bandwidth and fast transient response. Its internal compensation ensures unconditional stability at closed-loop gains ≥10V/V and ≤–9V/V, eliminating need for external phase compensation networks.
Designed for low-noise, high-fidelity analog signal paths, it maintains 1.2nV/√Hz input voltage noise up to 10kHz and exhibits <0.08° differential phase error in NTSC video applications. The dual-amplifier topology shares common supply rails while providing channel-to-channel crosstalk of –54dBc at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2 GHz - Enables stable closed-loop operation up to 290MHz at G=10, supporting high-frequency instrumentation and imaging signal chains. |
| Slew rate | 470 V/μs - Supports clean amplification of fast-rising pulses (e.g., 10-V step in <100 ns) without slewing distortion in SMU and pulse-echo systems. |
| Input voltage noise | 1.2 nV/√Hz - Critical for preserving SNR in low-level signal acquisition (e.g., ultrasound transducer preamplification). |
| THD @ 1MHz | –68 dBc (RL = 150Ω) - Ensures minimal harmonic contamination in precision AC measurements and high-fidelity analog outputs. |
| Output current | 200 mA (typical) - Drives low-impedance loads (e.g., 150Ω cables, ADC input buffers) without gain compression or thermal shutdown. |
| Supply range | ±4.5 V to ±16 V - Compatible with standard ±5V, ±12V, and ±15V industrial and test equipment power rails. |
| Settling time (0.1%) | 30 ns (G = –10) - Meets timing requirements for high-throughput data acquisition and real-time control loop feedback paths. |
Pinout & Package
THS4022IDRG4 is housed in an 8-pin HVSSOP (DGN) package with exposed thermal pad, optimized for high-speed layout and thermal dissipation (RθJA = 52°C/W). Pin numbering follows standard top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-current, low-impedance output node; requires short, direct routing to load to preserve bandwidth and minimize ringing. |
| 1IN– | Channel 1 inverting input | Differential input terminal; matched impedance routing critical to suppress common-mode noise in high-gain configurations. |
| 1IN+ | Channel 1 noninverting input | Differential input terminal; used with 1IN– to configure inverting/noninverting gain stages per channel. |
| VCC– | Negative power supply | Return path for both amplifiers; must be decoupled with low-ESR ceramic capacitors near pin 4. |
| 2IN+ | Channel 2 noninverting input | Independent input for second amplifier channel; enables dual-path signal processing without cross-coupling. |
| 2IN– | Channel 2 inverting input | Independent input for second amplifier channel; supports separate gain and feedback network per channel. |
| 2OUT | Channel 2 output | Second independent output; crosstalk to 1OUT is –54dBc at 1MHz, enabling tightly coupled dual-channel designs. |
| VCC+ | Positive power supply | Main supply rail; shared by both amplifiers; requires dedicated 0.1-μF + 4.7-μF decoupling at pin 8. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low voltage noise | 1.2 nV/√Hz enables detection of microvolt-level signals in medical ultrasound and precision metrology without added noise floor. |
| Gain ≥10V/V stability | No external compensation required - reduces BOM count and PCB area while ensuring predictable phase margin across temperature and process variation. |
| High output drive | 200 mA continuous sourcing/sinking allows direct interface to 150Ω coaxial lines, ADC drivers, and active filter stages without buffer stages. |
| Low distortion | –68 dBc THD at 1 MHz preserves spectral purity in RF sampling, spectrum analysis, and high-fidelity waveform generation. |
| Wide supply range | ±4.5 V to ±16 V operation supports legacy ±5V systems and modern ±12V/±15V test equipment without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032DR | Higher 350MHz bandwidth (DGN package), but 1.5nV/√Hz noise and reduced output drive (100mA typ). | Better for wideband RF IF amplification where bandwidth dominates over noise floor. | Select THS4032DR when bandwidth >300MHz is mandatory and noise budget allows +0.3nV/√Hz penalty. |
| OPA2691U | Lower 1.6nV/√Hz noise, 500MHz GBW, but unstable below G=5 and requires external compensation. | Suitable for fixed-gain ≥5 applications where layout can accommodate compensation components. | Choose OPA2691U only if design permits added compensation network and gain is fixed ≥5V/V. |
Compared with THS4022IDRG4, THS4032DR trades noise performance for higher bandwidth in same package, while OPA2691U demands careful stability design but offers superior GBW-making THS4022IDRG4 the optimal choice for gain-stable, low-noise dual-channel applications without layout overhead.

FAQ
What is the minimum stable gain for THS4022IDRG4?
The THS4022IDRG4 is unconditionally stable at closed-loop gains ≥10V/V and ≤–9V/V. This eliminates need for external phase compensation components, simplifying layout and improving reliability in high-gain instrumentation circuits. Gain settings below 10V/V require external compensation per TI's application notes.
Does THS4022IDRG4 support single-supply operation?
Yes, THS4022IDRG4 operates from 9V to 32V single supply (e.g., +12V or +24V), with input common-mode range extending to within 1.2V of rails and output swing to within 1.5V of rails under typical loads. For rail-to-rail input/output, consider TI's OPAx837 series instead.
What is the thermal resistance of THS4022IDRG4 in its HVSSOP-8 package?
The THS4022IDRG4 in HVSSOP-8 (DGN) package has RθJA = 52°C/W (junction-to-ambient) and RθJC(top) = 75.2°C/W. With proper PCB copper pour and thermal vias under the exposed pad, junction temperature rise remains within safe limits even at 200mA continuous output into 150Ω.
How does THS4022IDRG4 compare to THS4021 in terms of pin compatibility?
THS4022IDRG4 (dual) and THS4021 (single) are not pin-compatible: THS4021 uses SOIC-8 or HVSSOP-8 with offset null pins (1,8), while THS4022IDRG4 uses HVSSOP-8 with no null pins and dual-channel I/O mapping (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+). Board redesign is required for substitution.
What is the maximum output voltage swing for THS4022IDRG4 at ±15V supply?
At ±15V supply and RL = 250Ω, THS4022IDRG4 delivers ±12V to ±12.9V output swing (24–25.8Vpp); at RL = 1kΩ, swing improves to ±13V to ±13.6V. Output headroom is ~2.1V from each rail under heavy load, consistent across temperature and process corners.
