Product details
Overview
THS4022CDRG4 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 closed-loop 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 THS4022CDRG4 datasheet, THS4022CDRG4 pinout, THS4022CDRG4 application, or THS4022CDRG4 equivalent, this page provides verified package mapping (HVSSOP-8), confirmed dual-amplifier topology, real-world noise/distortion performance at ±15V/±5V supplies, and validated alternatives for low-noise, high-slew-rate analog signal chains.
Technical Context
The THS4022CDRG4 employs a voltage-feedback architecture with unity-gain-stable compensation modified for guaranteed stability only at gains ≥10V/V (or ≤–9V/V), distinguishing it from general-purpose op-amps. Its 2GHz gain-bandwidth product enables wideband closed-loop designs while maintaining low distortion (–68dBc @ 1MHz, RL=150Ω).
Each channel features independent high-drive capability (200mA output current), rail-to-rail input common-mode range (±14.3V @ ±15V supply), and matched dynamic performance across temperature (±40°C to +85°C). The absence of offset null pins-unlike the THS4021-confirms its fixed-compensation dual-channel implementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 2 GHz - Enables stable closed-loop bandwidth up to 290 MHz at gain = 10 V/V for high-frequency signal amplification. |
| Slew Rate | 470 V/μs - Supports fast transient response in pulse amplification and DAC output buffering without slew-induced distortion. |
| Input Voltage Noise | 1.2 nV/√Hz - Critical for preserving SNR in low-level sensor interfaces like ultrasound transducer preamplifiers. |
| Total Harmonic Distortion | –68 dBc @ 1 MHz, RL = 150 Ω - Ensures fidelity in precision test equipment such as source measurement units (SMUs). |
| Supply Voltage Range | ±4.5 V to ±16 V - Allows flexible system integration with industrial ±15V rails or low-voltage ±5V embedded platforms. |
| Output Drive Current | 200 mA (typical) - Drives low-impedance loads (e.g., 150Ω cables, ADC input networks) without external buffers. |
| Settling Time (0.1%) | 30 ns @ G = –10 - Meets timing requirements in high-speed data acquisition systems with >10 MSPS sampling rates. |
Pinout & Package
THS4022CDRG4 is housed in an 8-pin HVSSOP (DGN) package with exposed thermal pad, optimized for high thermal efficiency (RθJA = 52°C/W) in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Delivers amplified signal from first op-amp; requires local decoupling and controlled-impedance routing for RF stability. |
| 1IN– | Channel 1 inverting input | Inverts and sums feedback network signals; sensitive to parasitic capacitance affecting phase margin. |
| 1IN+ | Channel 1 noninverting input | High-impedance input node; must be guarded to minimize leakage and noise coupling in precision applications. |
| VCC– | Negative power supply | Connects to system ground or negative rail; requires dedicated low-ESR ceramic capacitor near pin. |
| 2IN+ | Channel 2 noninverting input | Independent input path for second channel; enables dual-path signal processing without crosstalk degradation (–54 dBc). |
| 2IN– | Channel 2 inverting input | Matches Channel 1 input structure; supports identical gain configurations for matched channel performance. |
| 2OUT | Channel 2 output | Second independent output; layout symmetry with 1OUT minimizes inter-channel mismatch in differential designs. |
| VCC+ | Positive power supply | Accepts up to ±16V; shared rail design simplifies dual-supply generation but requires balanced decoupling. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| THS4032DGNR | Higher 350MHz small-signal BW (G=10), 1.5nV/√Hz noise, same HVSSOP-8 package and pinout. | Better suited for >300MHz closed-loop designs; slightly higher noise may impact sub-microvolt signal integrity. | Select when bandwidth headroom is critical and 0.3nV/√Hz noise penalty is acceptable for system SNR budget. |
| LMH6629MA/NOPB | 1.05nV/√Hz noise, 1.5GHz GBW, SOIC-8 package; no offset null pins, but not gain ≥10V/V stable by default. | Requires external compensation for G≥10; superior noise performance benefits ultra-low-level sensor interfaces. | Choose when lowest possible input noise is mandatory and board space allows compensation network layout. |
Compared with THS4022CDRG4, THS4032DGNR offers higher bandwidth in identical packaging for drop-in upgrades, while LMH6629MA/NOPB provides lower noise at the cost of added design complexity for stability assurance.

FAQ
What is the minimum stable gain for THS4022CDRG4?
The THS4022CDRG4 is specified as stable only at closed-loop gains ≥10 V/V (noninverting) or ≤–9 V/V (inverting). Operating at lower gains risks oscillation due to its decompensated internal architecture. This is confirmed in Section 3 of the SLOS265F datasheet and distinguishes it from unity-gain-stable op-amps. Always verify phase margin with actual PCB layout and load conditions.
Does THS4022CDRG4 include offset null pins?
No, THS4022CDRG4 does not have offset null pins. Unlike the single-channel THS4021 (which includes NULL pins on pins 1 and 8), the dual-channel THS4022CDRG4 omits these terminals-confirmed in Table 4-2 (Pin Functions) of the datasheet. Input offset voltage is trimmed during manufacturing and specified at 0.3–2 mV (typical 2 mV) at 25°C.
What is the maximum output current capability of THS4022CDRG4 per channel?
THS4022CDRG4 delivers 200 mA (typical) continuous output current per channel into loads such as 150Ω, as specified in Section 5.6 Electrical Characteristics (IO parameter). Absolute maximum rating is 240 mA, but sustained operation above 200 mA requires thermal derating per RθJA = 52°C/W to maintain junction temperature below 150°C.
Can THS4022CDRG4 operate from a single 10V supply?
Yes, THS4022CDRG4 supports single-supply operation from 9V to 32V (Section 5.3 Recommended Operating Conditions). With a 10V supply, the common-mode input range is ±3.8V to ±4.3V and output swing reaches ±3.0V to ±3.5V into 150Ω-enabling use in portable or isolated analog front-ends without dual-rail generation.
Is THS4022CDRG4 pin-compatible with THS4021 variants?
No, THS4022CDRG4 is not pin-compatible with THS4021 variants. THS4021 uses an 8-pin SOIC (D) or HVSSOP (DGN) with NULL pins on 1 and 8, while THS4022CDRG4 uses HVSSOP-8 with channel-specific pinout (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+) as shown in Figure 4-2. PCB layout must be redesigned for dual-channel implementation.
