Product details
Overview
THS4022CDGNR from Texas Instruments is a dual-channel, ultra-low-noise (1.2nV/√Hz), high-speed voltage-feedback operational amplifier stable at gains ≥10V/V, delivering 290MHz small-signal bandwidth, 470V/μs slew rate, and 30ns 0.1% settling time - used in ultrasound scanner front-ends for analog beamforming and signal conditioning.
For engineers reviewing the THS4022CDGNR datasheet, THS4022CDGNR pinout, THS4022CDGNR application, or THS4022CDGNR equivalent, key selection criteria include gain stability at 10V/V, dual-channel crosstalk (–54dBc), ±4.5V to ±16V dual-supply operation, 200mA output drive, and low THD (–68dBc @ 1MHz) in precision high-frequency amplification.
Technical Context
The THS4022CDGNR employs a voltage-feedback architecture optimized for closed-loop gains ≥10V/V, with internal compensation enabling stability without external components. Its 290MHz –3dB bandwidth and 470V/μs slew rate support fast transient response in wideband signal chains.
It features dual independent amplifiers in an 8-pin HVSSOP package, each with rail-to-rail output swing capability (±12.9V @ ±15V, RL=250Ω), 1.2nV/√Hz input voltage noise below 10kHz, and channel-to-channel crosstalk of –54dBc at 1MHz - critical for multi-channel coherent acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 2 GHz - enables stable closed-loop operation up to 290MHz at G = 10V/V, supporting high-frequency instrumentation signal paths. |
| Slew Rate | 470 V/μs - ensures faithful reproduction of fast transients (e.g., ultrasound pulses) without slew-induced distortion. |
| Input Voltage Noise | 1.2 nV/√Hz - minimizes added noise in low-amplitude sensor interfaces like piezoelectric transducer preamps. |
| THD @ 1MHz | –68 dBc (RL = 150Ω) - meets stringent linearity requirements in power quality meter ADC driver stages. |
| Output Drive | 200 mA (typical) - drives low-impedance loads (e.g., 150Ω cables or ADC input networks) without gain compression. |
| Supply Range | ±4.5 V to ±16 V - supports flexible system-level power architecture, including ±5V and ±15V industrial rails. |
| Crosstalk | –54 dBc @ 1 MHz - preserves channel isolation in dual-channel SMU or differential receiver applications. |
Pinout & Package
THS4022CDGNR is housed in an 8-pin HVSSOP (DGN) package with exposed thermal pad, optimized for high-density PCB layouts and thermal performance (RθJA = 52°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Delivers amplified signal from Channel 1; capable of ±12.9V swing into 250Ω load at ±15V supply. |
| 1IN– | Channel 1 inverting input | Differential input node for Channel 1; supports common-mode range up to ±14.3V at ±15V supply. |
| 1IN+ | Channel 1 noninverting input | Differential input node for Channel 1; matched impedance and noise performance to 1IN–. |
| VCC– | Negative power supply | Reference return for both amplifiers; requires low-impedance bypassing near pin for stability. |
| 2IN+ | Channel 2 noninverting input | Independent input for Channel 2; electrically isolated from Channel 1 with –54dBc crosstalk at 1MHz. |
| 2IN– | Channel 2 inverting input | Independent input for Channel 2; maintains same DC and AC specs as Channel 1 inputs. |
| 2OUT | Channel 2 output | Delivers amplified signal from Channel 2; fully symmetric performance to 1OUT under identical conditions. |
| VCC+ | Positive power supply | Primary supply rail; supports up to ±16V operation with 7.5mA per amplifier quiescent current. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low voltage noise | 1.2nV/√Hz enables high-fidelity amplification of microvolt-level signals from medical transducers or precision sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6629MA/NOPB | Lower noise (0.94nV/√Hz), higher supply current (12.5mA), no offset null pins; single-channel only. | Requires two devices for dual-channel use; better suited for ultra-low-noise single-ended sensor interfaces. | Select when absolute minimum input noise dominates over channel count and power budget. |
| OPA2691IDGKR | Higher bandwidth (320MHz), lower THD (–72dBc), but higher input bias current (1.2µA vs 20µA typical); dual-channel in same DGN package. | Better for high-frequency communications; less ideal for high-impedance sensor nodes due to bias current sensitivity. | Select when wider small-signal bandwidth and lower distortion outweigh input bias current constraints. |
Compared with LMH6629MA/NOPB and OPA2691IDGKR, THS4022CDGNR offers balanced performance across noise, speed, drive strength, and dual-channel integration - making it optimal for space-constrained, multi-channel instrumentation where gain stability at 10V/V is mandatory.

FAQ
What is the minimum stable gain for THS4022CDGNR?
The THS4022CDGNR is specified as stable at closed-loop gains ≥10V/V and ≤–9V/V. It does not require external compensation at these gains, ensuring robust phase margin and predictable step response in fixed-gain configurations. This makes THS4022CDGNR suitable for precision gain blocks in ultrasound and SMU systems where stability is non-negotiable.
Does THS4022CDGNR support single-supply operation?
Yes, THS4022CDGNR supports single-supply operation from 9V to 32V, with recommended operating conditions specifying 9V to 30V. Input common-mode range extends to within 1.2V of the negative rail, and output swing reaches within 1.1V of each rail - enabling use in 12V or 24V industrial systems without level-shifting circuitry.
What is the thermal resistance (RθJA) of THS4022CDGNR?
The junction-to-ambient thermal resistance (RθJA) for THS4022CDGNR in its 8-pin HVSSOP (DGN) package is 52°C/W, per TI's SLOS265F datasheet Section 5.5. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves with PCB copper pour and thermal vias beneath the exposed pad.
How does THS4022CDGNR compare to THS4021 in terms of pin compatibility?
THS4022CDGNR is not pin-compatible with THS4021. The THS4021 (single-channel) uses pins 1 and 8 for offset nulling, while THS4022CDGNR repurposes those pins as 1OUT and VCC+, respectively. Their pinouts differ fundamentally - THS4022CDGNR has dedicated 1OUT, 2IN+, 2IN–, and 2OUT pins, whereas THS4021 has NULL, IN–, IN+, OUT, NC, and VCC±.
What is the maximum output current specification for THS4022CDGNR?
The absolute maximum output current for THS4022CDGNR is ±240mA (per amplifier), per Section 5.1 Absolute Maximum Ratings. Under recommended operating conditions (±15V, RL = 10Ω), typical continuous output current is 200mA - sufficient to drive 150Ω transmission lines or low-impedance ADC inputs without clipping or thermal shutdown.
