Product details
Overview
AD8022ARMZ-REEL7 from Analog Devices is a dual, low-noise, high-speed voltage-feedback operational amplifier optimized for xDSL receiver front ends. It delivers 130 MHz bandwidth (−3 dB, G = +1), 2.5 nV/√Hz input voltage noise at 100 kHz, and 50 V/μs slew rate on ±12 V supply, enabling high-fidelity signal conditioning in ADSL/VDSL line interface circuits.
For engineers reviewing the AD8022ARMZ-REEL7 datasheet, AD8022ARMZ-REEL7 pinout, AD8022ARMZ-REEL7 application, or AD8022ARMZ-REEL7 equivalent, this page provides verified specifications, functional context for differential receiver design, real-world MTPR performance data, and validated alternative options for low-noise, high-bandwidth op amp selection.
Technical Context
The AD8022ARMZ-REEL7 integrates two independent amplifiers fabricated on Analog Devices' XFCB bipolar process, supporting wide supply range (±2.5 V to ±12 V) and delivering low distortion (MTPR < −66 dBc at G = +7) with fast overvoltage recovery (200 ns). Its folded-cascode input stage enables 2.5 nV/√Hz voltage noise while maintaining 4.0 mA/amp quiescent current.
Each amplifier features rail-to-rail output swing (±10.1 V on ±12 V), 75 pF capacitive load drive capability, and high CMRR (98 dB), making it suitable for differential active filters and ADC buffer stages where signal integrity across 100 kHz–130 MHz is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (−3 dB) | 130 MHz at G = +1, ±12 V - supports full-rate DMT tone reception up to 1.1 MHz with flat gain response |
| Voltage Noise | 2.5 nV/√Hz @ 100 kHz - preserves SNR in ADSL receivers where background noise is ~31 nV/√Hz |
| Slew Rate | 50 V/μs - ensures faithful reproduction of fast transient signals in ultrasound preamps and active filters |
| Settling Time (0.1%) | 62 ns - meets timing requirements for 16-bit ADC buffering with minimal acquisition error |
| Multitone Power Ratio | −66 dBc (26 kHz–132 kHz, G = +7) - quantifies inter-subband crosstalk suppression in DMT systems |
| Output Swing | ±10.1 V into 500 Ω - drives transformer-coupled line interfaces without clipping at full-scale DMT signals |
| Quiescent Current | 4.0 mA per amplifier - enables dual-channel low-power operation in space-constrained xDSL modems |
Pinout & Package
AD8022ARMZ-REEL7 is packaged in an 8-lead MSOP (RM-8) with exposed pad, measuring 3.0 mm × 3.0 mm × 0.85 mm. The package is RoHS-compliant and rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives first differential leg of xDSL hybrid; supports ±10.1 V swing into 500 Ω |
| 2 (−IN1) | Inverting input, Amp 1 | Accepts transformer-coupled negative line signal; 0.7 pF input capacitance minimizes phase shift |
| 3 (+IN1) | Non-inverting input, Amp 1 | Accepts transformer-coupled positive line signal; common-mode range extends to ±11.75 V |
| 4 (−VS) | Negative supply rail | Connects to −2.5 V to −12 V; requires local 0.1 μF + 10 μF decoupling |
| 5 (+VS) | Positive supply rail | Connects to +2.5 V to +12 V; same decoupling as −VS for PSRR > 80 dB |
| 6 (OUT2) | Amplifier 2 output | Drives second differential leg; matched dynamic performance to OUT1 enables balanced receiver design |
| 7 (−IN2) | Inverting input, Amp 2 | Matches −IN1 characteristics; enables identical gain/phase response for differential pair |
| 8 (+IN2) | Non-inverting input, Amp 2 | Matches +IN1; supports common-mode rejection > 98 dB across −40°C to +85°C |
Key Features
| Feature | Design Value |
|---|---|
| Low voltage noise | 2.5 nV/√Hz @ 100 kHz - reduces added noise floor below twisted-pair background noise (31 nV/√Hz) |
| Dual independent amplifiers | Matched bandwidth (130 MHz), slew rate (50 V/μs), and offset (±6 mV max) - enables true differential receiver implementation |
| Capacitive load drive | Stable with up to 75 pF - eliminates need for isolation resistors when driving ADC inputs or filter networks |
| Wide supply range | ±2.5 V to ±12 V - supports both low-voltage portable DSL modems and high-dynamic-range line cards |
| Fast overdrive recovery | 200 ns - recovers cleanly after line transients or impulse noise events in subscriber loop environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4898-2ARMZ | Lower voltage noise (1.0 nV/√Hz), higher quiescent current (10.5 mA/amp), SOIC-8 only | Better SNR in ultra-low-noise instrumentation; less suitable for power-constrained DSL modems | Select when voltage noise dominates system budget and supply current > 8 mA/amp is acceptable |
| LMH6629MA/NOPB | Higher slew rate (1000 V/μs), wider bandwidth (1.5 GHz), but 4.5 nV/√Hz noise and no MSOP option | Preferred for RF/IF gain blocks; not optimized for DMT multitone linearity or transformer-coupled inputs | Select for GHz-range signal chains where MTPR and low-frequency noise are secondary concerns |
Compared with ADA4898-2ARMZ and LMH6629MA/NOPB, AD8022ARMZ-REEL7 uniquely balances 2.5 nV/√Hz noise, 130 MHz bandwidth, 4.0 mA/amp supply current, and MSOP-8 packaging-making it the only dual op amp qualified for cost-sensitive, space-constrained xDSL receiver designs requiring proven MTPR < −66 dBc performance.

FAQ
What is the maximum supply voltage rating for AD8022ARMZ-REEL7?
The AD8022ARMZ-REEL7 has an absolute maximum supply voltage rating of ±13.0 V (26.4 V total across +VS and −VS). Operation beyond this risks permanent damage. Recommended operating range is ±2.5 V to ±12 V, with tested performance including 130 MHz bandwidth and 2.5 nV/√Hz noise at ±12 V.
Does AD8022ARMZ-REEL7 support single-supply operation?
AD8022ARMZ-REEL7 is specified for dual-supply operation (±2.5 V to ±12 V) and does not support true single-supply use. Its input common-mode range extends to within 0.75 V of either rail, but the datasheet provides no characterization for +12 V/0 V or +5 V/0 V configurations. Figure 41 shows a +12 V single-rail adaptation using external biasing, but that circuit relies on external components-not internal architecture.
What is the MTPR performance of AD8022ARMZ-REEL7 in ADSL applications?
AD8022ARMZ-REEL7 achieves −66 dBc MTPR in the 144 kHz to 1.1 MHz band and −67.2 dBc in the 26 kHz to 132 kHz band under full-rate ADSL DMT conditions (G = +7, ±12 V, 500 Ω load), as measured per Figure 24–25 of the Rev. C datasheet. This performance directly enables compliance with ITU-T G.992.1 line coding requirements.
Is AD8022ARMZ-REEL7 pin-compatible with other AD80xx-series op amps?
No. AD8022ARMZ-REEL7 uses an 8-lead MSOP (RM-8) package with a unique pinout: OUT1/−IN1/+IN1/−VS/+VS/OUT2/−IN2/+IN2. It is not pin-compatible with AD8001 (SO-8), AD8009 (SO-8), or AD8021 (SO-8/MSOP-8 with different pin mapping). Pin compatibility must be verified per each device's specific outline drawing.
What decoupling is required for stable operation of AD8022ARMZ-REEL7?
AD8022ARMZ-REEL7 requires local decoupling at each supply pin: a 0.1 μF ceramic capacitor placed ≤1.5 mm from the pin, plus a 10 μF bulk capacitor nearby. Layout guidelines (Figure 40 and Page 15) mandate ground-plane coverage, short feedback traces, and placement of termination resistors adjacent to inputs/outputs to prevent oscillation or gain peaking.
