Product details
Overview
OPA2822E/250 from Texas Instruments is a dual, wideband, low-noise voltage-feedback operational amplifier optimized for xDSL differential line receivers and high-dynamic-range ADC drivers. It delivers 2.0nV/√Hz input voltage noise, 500MHz unity-gain bandwidth, and –105dBc third-harmonic distortion at 1MHz with 2VPP differential output - enabling >14-bit dynamic range in baseband I/Q receiver channels.
For engineers reviewing the OPA2822E/250 datasheet, OPA2822E/250 pinout, OPA2822E/250 application, or OPA2822E/250 equivalent, key selection criteria include low-noise performance under single +5V or ±6V operation, differential configuration stability, harmonic distortion vs. load resistance, and MSOP-8 thermal limitations (θJA = 150°C/W).
Technical Context
The OPA2822E/250 employs a unity-gain stable voltage-feedback architecture with 240MHz gain-bandwidth product and 170V/µs slew rate (±6V), supporting high-fidelity signal conditioning in broadband communications front-ends. Its differential input stage achieves 110dB CMRR and ±4.8V common-mode input range at ±6V, while maintaining 90mA output current per channel into 100Ω loads.
Designed for precision analog signal paths, it features matched channel-to-channel crosstalk of –95dBc at 1MHz and supports both noninverting (G ≥ +1) and inverting (G ≤ –1) configurations with validated small-signal bandwidths up to 400MHz (G = +1) and 350MHz (G = +1, +5V supply). Input voltage noise remains flat >10kHz, and distortion performance is specified for RL ≥ 500Ω to ensure SFDR integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 2.0nV/√Hz @ >10kHz - enables ultra-low-noise pre-amplification before high-resolution ADCs |
| Unity-Gain Bandwidth | 500MHz - supports wideband signal acquisition up to Nyquist frequency of 14-bit+ converters |
| Harmonic Distortion (3rd) | ≤ –105dBc @ 1MHz, 2VPP, RL ≥ 500Ω - preserves SFDR >90dB in differential I/Q channels |
| Output Current | ±90mA min per channel - drives passive filters or 100Ω loads without gain compression |
| Supply Range | +5V to +12V single or ±5V to ±6.3V dual - compatible with legacy xDSL line card power rails |
| Quiescent Current | 4.8mA/ch @ ±6V - balances performance and power in multi-channel receiver designs |
| Common-Mode Rejection | 110dB min @ ±1V - rejects coupled interference in unshielded twisted-pair interfaces |
Pinout & Package
OPA2822E/250 is housed in an 8-pin MSOP package (DGK), measuring 3.0mm × 3.0mm × 1.0mm with 0.65mm pitch. Thermal resistance θJA = 150°C/W limits continuous output power in high-density layouts without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–VS) | Negative Supply | Connect to ground (single-supply) or negative rail (dual-supply); decoupling required within 1cm |
| 2 (+In B) | Inverting Input Channel B | Differential pair input for second amplifier; requires matched impedance to minimize CMRR degradation |
| 3 (–In B) | Noninverting Input Channel B | DC-coupled input node; bias current cancellation requires matched resistive network on both inputs |
| 4 (Out B) | Output Channel B | Capable of ±90mA sourcing/sinking; series resistor recommended for capacitive loads >10pF |
| 5 (Out A) | Output Channel A | Independent output; layout symmetry critical for <0.03° differential phase error in video/I/Q apps |
| 6 (+In A) | Noninverting Input Channel A | Primary input for first amplifier; input impedance 15kΩ||1pF at +2.5V common-mode |
| 7 (–In A) | Inverting Input Channel A | Feedback node; sensitive to parasitic capacitance - keep trace short and guard with ground |
| 8 (+VS) | Positive Supply | Accepts +5V to +12V; bypass with 0.1µF ceramic + 6.8µF tantalum near pin |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Voltage Noise | 2.0nV/√Hz enables >14-bit ENOB in 5MHz baseband I/Q receivers without external filtering |

| Differential Configuration Stability | Validated –105dBc 3rd-harmonic distortion at 1MHz ensures >90dB SFDR in xDSL line receiver differential pairs |
| Wide Supply Flexibility | Operates from +5V single supply to ±6V - eliminates need for separate low-noise LDOs in mixed-voltage systems |
| Matched Channel Performance | –95dBc channel-to-channel crosstalk at 1MHz minimizes inter-channel interference in dual-path I/Q demodulators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2686IDGKT | 1.3nV/√Hz input noise, 1.2GHz GBW, but higher 7.5mA/ch quiescent current and no MSOP-8 option | Better noise performance suits RF sampling ADC drivers; less suitable for space-constrained xDSL line cards | Select when absolute lowest noise dominates over power and footprint constraints |
| THS6062IDGNR | 1.5nV/√Hz noise, 220V/µs slew rate, but only specified for ±5V operation and lacks –105dBc distortion validation at 1MHz | Optimized for video distribution; limited DC accuracy and thermal derating in MSOP packages | Prefer for cost-sensitive video amplification where 14-bit SFDR is not required |
Compared with OPA2686IDGKT and THS6062IDGNR, the OPA2822E/250 uniquely balances 2.0nV/√Hz noise, 500MHz bandwidth, –105dBc distortion, and MSOP-8 packaging - making it the only option qualified for space-limited, high-SFDR xDSL receiver designs requiring single +5V compatibility and guaranteed differential performance.

FAQ
What supply voltages does the OPA2822E/250 support?
The OPA2822E/250 operates from a single +5V to +12V supply or dual ±5V to ±6.3V supplies. At +5V, it delivers 3.9V maximum positive output swing and 1.3V minimum positive output swing with 100Ω load - enabling 2.6VPP clean output. Full electrical specifications are validated across –40°C to +85°C for both supply configurations. The OPA2822E/250 maintains 2.0nV/√Hz input noise and –105dBc distortion across this entire range.
Does the OPA2822E/250 support differential output configurations?
Yes, the OPA2822E/250 is explicitly characterized for differential operation in xDSL receiver applications. TI provides dedicated differential test circuits (SBOS188E Figures 10–14) showing –105dBc third-harmonic distortion at 1MHz with 4VPP differential output into 400Ω load. Channel-to-channel crosstalk is –95dBc at 1MHz, and differential gain/phase errors are 0.02% and 0.03° - confirming suitability for precision I/Q signal paths. The OPA2822E/250 achieves this without external matching components due to internal die-level matching.
What is the thermal limitation of the OPA2822E/250 in MSOP-8 package?
The OPA2822E/250 in MSOP-8 (DGK) package has a junction-to-ambient thermal resistance θJA of 150°C/W. With 9.6mA max quiescent current per channel and ±90mA output drive, power dissipation can reach ~1.2W under worst-case conditions. Derating is required above +70°C ambient; TI specifies maximum junction temperature of +150°C. For continuous 2VPP output into 100Ω at +85°C, PCB copper area and airflow must be designed to limit ΔT to ≤75°C. The OPA2822E/250 datasheet includes thermal characterization curves for SO-8 and MSOP variants.
How does the OPA2822E/250 compare to the OPA2822U in SO-8 package?
The OPA2822E/250 and OPA2822U share identical silicon die and electrical specifications, differing only in package: MSOP-8 (DGK) vs SO-8 (D). The OPA2822E/250 offers 3.0mm × 3.0mm footprint (43% smaller) but higher θJA (150°C/W vs 125°C/W), requiring more careful thermal design. Both use identical marking "D22" and operate across –40°C to +85°C. Pinout is identical, enabling drop-in replacement where board space allows. The OPA2822E/250 is optimized for high-density xDSL line cards where size outweighs thermal margin.
Is the OPA2822E/250 suitable for driving ADC inputs directly?
Yes, the OPA2822E/250 is qualified for direct driving of high-speed ADC inputs, particularly 14-bit+ SAR and pipeline converters. Its 170V/µs slew rate, 500MHz bandwidth, and 0.02% settling to 0.02% in 35ns ensure minimal acquisition error. Output impedance is 0.01Ω at 100kHz, minimizing interaction with ADC input capacitance. TI validates performance driving 100Ω loads - matching typical ADC input termination - and specifies distortion down to 200mVPP output for optimal SNR. The OPA2822E/250 maintains 2.0nV/√Hz noise floor even under these conditions.
