Product details
Overview
AD8017ARZ from Analog Devices is a dual high-speed current-feedback (CF) amplifier optimized for xDSL line driving, delivering 200 mA output current per channel into 25 Ω while maintaining –78 dBc SFDR at 500 kHz and 160 MHz –3 dB bandwidth (G = +2) under ±6 V supply. It operates across –40°C to +85°C and features rail-to-rail output swing within 1.0 V of supply rails.
For engineers reviewing the AD8017ARZ datasheet, AD8017ARZ pinout, AD8017ARZ application, or AD8017ARZ equivalent, key selection criteria include differential drive capability in ADSL/SDSL/VDSL modems, high-current low-distortion performance at 1–10 MHz, thermal management in Thermal Coastline SOIC-8, and compatibility with single-supply (5–12 V) or dual-supply (±2.2–±6.0 V) configurations.
Technical Context
The AD8017ARZ employs a two-stage complementary current-feedback architecture-distinct from traditional single-stage Nelson amplifiers-enabling higher GBWP, lower distortion under heavy loads, and improved open-loop gain isolation. Its design minimizes signal-dependent quiescent current modulation and supports stable operation with wide common-mode input/output voltage ranges.
As a CF amplifier, its closed-loop bandwidth varies minimally with external gain-setting resistor (RG), unlike voltage-feedback op amps. It achieves 1600 V/µs slew rate and 2.0 ns rise/fall time (G = +2, RL = 100 Ω), enabling faithful reproduction of fast DSL upstream signals up to 135 kHz (ADSL over POTS) and 276 kHz (ADSL over ISDN).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 160 MHz at G = +2, ±6 V supply - supports full DMT tone spectrum without attenuation |
| Slew Rate | 1600 V/µs - ensures minimal slewing-induced distortion on fast DSL transients |
| Output Current | 200 mA per channel into 25 Ω at 1 MHz with < –58 dBc highest harmonic - meets ADSL peak current demand |
| SFDR | –78 dBc at 500 kHz, RL = 100 Ω - satisfies xDSL spectral purity requirements for upstream transmission |
| Supply Current | 7.7 mA per amplifier at 25°C - enables low-power CPE designs with total ~25 mA system draw |
| Input Noise | 1.9 nV/√Hz at 10 kHz - preserves SNR in high-gain front-end stages |
| Operating Temp | –40°C to +85°C - qualified for commercial-grade customer premise equipment deployment |
Pinout & Package
AD8017ARZ is housed in an 8-lead Thermal Coastline SOIC (SO-8) package, featuring enhanced thermal dissipation via copper-plated leadframe and optimized internal die attach. The package requires no external heatsink when mounted on a 4-layer PCB with adequate copper pour on power pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | +IN1 | Noninverting input of Channel 1 - high-impedance (50 kΩ), low-capacitance (2.4 pF) node for precision signal routing |
| 2 | –IN1 | Inverting input of Channel 1 - matched to +IN1 for optimal CMRR (63 dB) and balanced feedback |
| 3 | OUT1 | Output of Channel 1 - capable of ±5.0 V swing into 25 Ω, drives transformer primary or differential line load |
| 4 | –VS | Negative supply rail - ac ground reference; connects to large copper pour for thermal and noise control |
| 5 | +VS | Positive supply rail - ac ground reference; same thermal role as Pin 4 in dual-supply configuration |
| 6 | OUT2 | Output of Channel 2 - independent, fully matched to OUT1 for true differential drive (e.g., Figure 2, Figure 8) |
| 7 | –IN2 | Inverting input of Channel 2 - electrically isolated from Channel 1; crosstalk –66 dB at 5 MHz |
| 8 | +IN2 | Noninverting input of Channel 2 - identical specs to Pin 1; enables dual-channel synchronous line driving |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel current-feedback topology | Enables simultaneous high-fidelity differential drive with < 2 ns propagation skew between channels |
| Thermal Coastline SOIC-8 packaging | Reduces θJA to 95°C/W on 2-layer board - eliminates need for external heatsink in typical DSL PCB layouts |
| Rail-to-rail output swing | Delivers ±4.6 V into 25 Ω on ±6 V supplies - maximizes dynamic range for 20 Vp-p differential line signals |
| Low distortion at high current | Maintains –78 dBc SFDR while sourcing 200 mA - avoids clipping-induced intermodulation in multi-tone DMT systems |
| Single-supply operability | Functions from 5 V to 12 V - simplifies integration into PC-based PCI cards and consumer modems using available 12 V rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-current, high-speed amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8016ARZ | Single-channel version; identical specs except 50% lower quiescent current (3.8 mA) and no crosstalk spec | Requires two units for differential drive; increases board area and layout complexity vs. integrated dual-channel AD8017ARZ | Select AD8016ARZ only when space allows separate channel routing and thermal isolation is critical |
| THS3091D | Higher slew rate (2000 V/µs), but lower output current (160 mA) and no guaranteed –78 dBc SFDR at 500 kHz into 100 Ω | Optimized for test equipment, not DSL line driving; lacks thermal package optimization for continuous 200 mA operation | Prefer THS3091D for wideband pulse applications where peak speed outweighs sustained linearity |
Compared with AD8016ARZ and THS3091D, the AD8017ARZ uniquely combines dual-channel integration, 200 mA sustained drive, –78 dBc SFDR at DSL frequencies, and Thermal Coastline SOIC-8 thermal efficiency-making it the only drop-in solution for cost-sensitive, space-constrained xDSL CPE designs requiring validated linearity and reliability.

FAQ
What is the maximum output voltage swing of the AD8017ARZ into a 25 Ω load?
The AD8017ARZ delivers ±4.6 V (9.2 Vp-p) output voltage swing into a 25 Ω load at ±6 V supply, enabling 20 Vp-p differential output when used in push-pull configuration-sufficient for ADSL line power requirements up to 13 dBm. This swing is maintained while sourcing 200 mA per channel with distortion below –58 dBc at 1 MHz, as verified in the datasheet's Output Voltage Swing specification table.
Can the AD8017ARZ operate from a single 5 V supply?
Yes, the AD8017ARZ supports single-supply operation from 5 V to 12 V, with full functionality including rail-to-rail output swing and specified distortion performance. At 5 V, quiescent current drops to ~6.2 mA per amplifier, and –3 dB bandwidth remains 120 MHz (G = +2). The device's wide input common-mode range (±1.6 V at 2.5 V supply) and output swing capability make it suitable for low-voltage consumer DSL modems without level-shifting circuitry.
How does the Thermal Coastline SOIC-8 package improve thermal performance compared to standard SOIC-8?
The AD8017ARZ's Thermal Coastline SOIC-8 package uses a proprietary copper-plated leadframe that lowers thermal resistance by directing heat through the leads into the PCB copper, achieving θJA = 95°C/W on a 2-layer board-significantly better than standard SOIC-8 (typically >150°C/W). This allows the AD8017ARZ to dissipate up to 1.3 W continuously without external heatsink when mounted on a 4-layer board with optimized copper pour on Pins 4 (–VS) and 5 (+VS), as confirmed in the Absolute Maximum Ratings and Thermal Considerations sections.
What is the recommended gain configuration for ADSL differential drive using the AD8017ARZ?
The AD8017ARZ is typically configured in inverting mode (G = –1) for ADSL differential drive, as shown in Figure 5 and the Application section. This provides symmetrical signal inversion across both channels, minimizing even-order harmonics and enabling clean 180° phase relationship required for transformer-coupled line driving. Gain-setting resistors of 54.4 Ω (RF = RG) yield precise –1 gain, and the current-feedback architecture ensures bandwidth stability regardless of gain-setting resistor value.
Does the AD8017ARZ require external compensation for stability with capacitive loads?
No, the AD8017ARZ is internally compensated for unity-gain stability and remains stable driving ≥100 pF capacitive loads without external compensation, as verified in TPC 26 (RS and CL vs. 30% Overshoot). However, for loads exceeding 100 pF or low-impedance cables, a small series resistor (e.g., 10–22 Ω) at the output is recommended to isolate capacitance and maintain phase margin-consistent with standard high-speed amplifier layout practices documented in the datasheet's Layout Guidelines.
