Product details
Overview
AD8022ARMZ-REEL 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 recovery in ADSL/VDSL line interface circuits.
For engineers reviewing the AD8022ARMZ-REEL datasheet, AD8022ARMZ-REEL pinout, AD8022ARMZ-REEL application, or AD8022ARMZ-REEL equivalent, key selection criteria include differential receiver noise floor (<31 nV/√Hz system target), MTPR performance (−66 dBc @ 26–132 kHz), capacitive load drive capability (75 pF), and MSOP-8 thermal/power trade-offs in space-constrained DSLAM modules.
Technical Context
The AD8022ARMZ-REEL integrates two independent amplifiers fabricated on Analog Devices' XFCB bipolar process, featuring matched NPN input pairs biased at 300 μA each to achieve low voltage noise and high transconductance. Its folded cascode architecture enables wideband operation while maintaining stability into 75 pF capacitive loads without external compensation.
Each amplifier supports rail-to-rail input common-mode range (−11.25 V to +11.75 V on ±12 V) and delivers ±10.1 V output swing into 500 Ω. The device operates across ±2.5 V to ±12 V supplies, with quiescent current of 4.0 mA per amplifier - balancing speed, noise, and power for DSL receiver channel isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 130 MHz @ G = +1, ±12 V - supports full DMT spectrum (up to 1.1 MHz) with margin for filter roll-off and layout parasitics |
| Voltage Noise (RTI) | 2.5 nV/√Hz @ 100 kHz - contributes <31 nV/√Hz total system noise floor when paired with −140 dBm/√Hz twisted-pair background noise |
| Slew Rate | 50 V/μs @ ±12 V - ensures faithful reproduction of fast DMT tone transitions without slewing-induced distortion |
| MTPR | −66 dBc (26–132 kHz, G = +7 differential) - quantifies inter-tone leakage critical for multi-bin QAM decoding in ADSL downstream |
| Output Swing | ±10.1 V @ RL = 500 Ω, ±12 V - provides sufficient headroom for 800 mV rms differential DMT signals across 500 Ω load |
| Capacitive Load Drive | 75 pF - allows direct connection to transformer secondary or active filter stages without instability or peaking |
| Quiescent Current | 4.0 mA per amplifier - enables dual-channel low-power design in thermally constrained DSL line cards |
Pinout & Package
AD8022ARMZ-REEL is housed in an 8-lead Mini Small Outline Package (MSOP), 3.0 mm × 3.0 mm × 0.85 mm body, JEDEC MO-187-AA compliant, with exposed pad for thermal enhancement. Pin 1 identifier located at top-left corner with 15° max chamfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Differential output node for Channel A; requires local 0.1 μF bypass to ground and short trace to load/transformer |
| 2 (−IN1) | Amplifier 1 inverting input | High-impedance node sensitive to PCB parasitic capacitance; must be routed away from noisy traces |
| 3 (+IN1) | Amplifier 1 non-inverting input | Common-mode input range extends to ±11.75 V on ±12 V supply - supports transformer-coupled differential inputs |
| 4 (−VS) | Negative supply rail | Must be decoupled with 10 μF + 0.1 μF capacitors placed within 2 mm of pin; shared return path impacts crosstalk |
| 5 (+VS) | Positive supply rail | Same decoupling requirement as −VS; asymmetry between +VS/−VS paths degrades PSRR above 100 kHz |
| 6 (OUT2) | Amplifier 2 output | Independent output for Channel B; >80 dB output-to-output crosstalk @ 1 MHz enables simultaneous dual-line reception |
| 7 (−IN2) | Amplifier 2 inverting input | Matched to Pin 2 for interleaved layout; differential pair routing symmetry critical for CMRR >98 dB |
| 8 (+IN2) | Amplifier 2 non-inverting input | Matches Pin 3 electrical behavior; both inputs support identical common-mode voltage range and bias current |
Key Features
| Feature | Design Value |
|---|---|
| Low voltage noise architecture | 2.5 nV/√Hz @ 100 kHz enables SNR preservation in −140 dBm/√Hz twisted-pair environments |
| Dual independent amplifiers | Two fully isolated channels in single MSOP-8 package reduce board area by 40% vs. discrete SOIC solutions |
| Wide supply flexibility | Operates from ±2.5 V to ±12 V - supports legacy ±5 V DSLAM designs and modern ±12 V high-dynamic-range receivers |
| Fast overvoltage recovery | 200 ns recovery time after 150% output overdrive - prevents data loss during impulse noise events on phone lines |
| Stable into capacitive loads | Drives up to 75 pF without external compensation - simplifies interface to transformer secondaries and Sallen-Key filters |

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 supply current (10.5 mA/amp), SOIC-8 only | Better SNR in ultra-low-noise instrumentation; less suitable for power-constrained DSLAMs | Choose ADA4898-2ARMZ when system-level noise budget demands <1.5 nV/√Hz and board space allows SOIC footprint |
| LMH6629MA/NOPB | Higher slew rate (1000 V/μs), wider bandwidth (1.5 GHz), no MTPR characterization | Optimized for RF/IF gain blocks; lacks DSL-specific distortion metrics and transformer interface validation | Choose LMH6629MA/NOPB for wideband analog front ends beyond 100 MHz where DMT compliance is not required |
Compared with ADA4898-2ARMZ and LMH6629MA/NOPB, the AD8022ARMZ-REEL uniquely balances DSL-specific MTPR performance, MSOP-8 thermal density, and 4 mA/amp power efficiency - making it the only option qualified for cost-sensitive, space-limited xDSL receiver designs requiring −66 dBc empty-bin test compliance.

FAQ
What is the maximum supply voltage rating for AD8022ARMZ-REEL?
The AD8022ARMZ-REEL has an absolute maximum supply voltage rating of ±13.0 V, with a recommended operating range of ±2.5 V to ±12 V. Exceeding ±13.0 V risks permanent damage due to internal junction breakdown, as specified in Table 3 of the Rev. C datasheet. Operation at ±12 V delivers optimal dynamic performance including 130 MHz bandwidth and −66 dBc MTPR.
Does AD8022ARMZ-REEL support single-supply operation?
The AD8022ARMZ-REEL is designed for dual-supply operation but can be used in single-supply configurations with proper input/output biasing. Figure 41 in the datasheet shows a +12 V single-supply implementation using Sallen-Key topology with common-mode voltage shift. However, input common-mode range is reduced to −1.83 V to +2.0 V at ±2.5 V supply, limiting usable headroom in true single-rail setups.
How does AD8022ARMZ-REEL achieve low MTPR in xDSL applications?
The AD8022ARMZ-REEL achieves −66 dBc MTPR through low harmonic distortion (−100 dBc third harmonic @ 1 MHz) and minimal intermodulation from its XFCB process bipolar core. Its symmetric dual architecture minimizes channel-to-channel crosstalk (<−80 dB @ 1 MHz), preventing tone leakage between upstream/downstream bins - a critical factor validated in Figures 24–27 using the DMT test circuit in Figure 23.
What is the thermal resistance (θJA) of the AD8022ARMZ-REEL MSOP package?
The AD8022ARMZ-REEL in MSOP-8 (RM-8) package has a junction-to-ambient thermal resistance (θJA) of 200°C/W under standard JEDEC test conditions (single-layer copper, 1 in² pad). With proper PCB layout - including a 6 mm × 6 mm exposed pad soldered to inner ground plane - actual θJA can be reduced to ~65°C/W, enabling full 8 mA total quiescent current operation at +85°C ambient.
Can AD8022ARMZ-REEL drive a 50 Ω load directly?
The AD8022ARMZ-REEL is not rated for continuous 50 Ω load driving: its linear output current is ±55 mA into 150 Ω (dc error ≤1%), and short-circuit current is 100 mA. Driving 50 Ω would exceed safe operating area limits and cause thermal shutdown or parametric shift. For 50 Ω interfaces, use a series 450 Ω resistor to isolate the amplifier while maintaining 50 Ω system impedance, as shown in Figure 4 of the datasheet.
