Product details
Overview
AD8029ARZ-REEL from Analog Devices is a single-channel, rail-to-rail input/output high-speed voltage feedback amplifier optimized for low-power, wideband signal conditioning in single-supply systems. It delivers 125 MHz –3 dB bandwidth (G = +1), 60 V/µs slew rate, and 80 ns settling time to 0.1%, operating from 2.7 V to 12 V supply with only 1.3 mA quiescent current per amplifier. It is widely used as an A-to-D driver and buffer in battery-powered instrumentation and automotive vision systems.
For engineers reviewing the AD8029ARZ-REEL datasheet, AD8029ARZ-REEL pinout, AD8029ARZ-REEL application, or AD8029ARZ-REEL equivalent, key selection considerations include its SOIC-8 package, disable pin functionality, rail-to-rail swing within 40 mV of rails, ±200 mV beyond-rail input capability, and verified performance at +3 V, +5 V, and ±5 V supplies.
Technical Context
The AD8029ARZ-REEL employs Analog Devices' proprietary XFCB process to achieve high-speed operation with ultra-low power consumption. Its input stage supports true single-supply operation across –0.2 V to +5.2 V common-mode range (at +5 V supply) without phase reversal, while the output stage delivers rail-to-rail swing with <40 mV headroom under 1 kΩ load.
It features an active-disable function (pin 5) enabling low-power standby mode with 150–200 µA quiescent current, fast turn-on/turn-off times (<95 ns / <165 ns), and >55 dB off-isolation at 1 MHz - critical for multiplexed or power-gated signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 125 MHz at G = +1, +5 V supply - enables baseband video, sensor interface, and ADC sampling up to ~60 MSPS without gain peaking. |
| Slew Rate | 60 V/µs - supports full-scale step response for 2 V p-p signals in <33 ns, minimizing distortion in fast transient applications. |
| Settling Time | 80 ns to 0.1% - ensures accurate digitization of multi-step waveforms in pipeline or SAR ADC front-ends. |
| Input Voltage Range | Extends 200 mV beyond supply rails - eliminates need for level-shifting in single-supply systems interfacing to sensors or DACs. |
| Output Swing | Within 40 mV of each rail (RL = 1 kΩ) - maximizes dynamic range for 12-bit+ ADCs powered from 3.3 V or 5 V rails. |
| Quiescent Current | 1.3 mA per amplifier - enables >100-hour operation on coin-cell batteries in portable test equipment. |
| Disable Current | 150–200 µA when DISABLE = Low - reduces system standby power by >90% versus active mode. |
Pinout & Package
AD8029ARZ-REEL is housed in an 8-lead SOIC (Small Outline Integrated Circuit) package, RoHS-compliant, with standard JEDEC MS-012AC footprint (5.0 mm × 4.0 mm, 1.27 mm pitch). Pin 1 is marked with a notch or dot; pins are numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must be left floating or tied to ground per layout best practice to minimize parasitic coupling. |
| 2 | Inverting Input (–IN) | Differential input node; high-impedance (6 MΩ), low capacitance (2 pF); sensitive to PCB trace length and guarding. |
| 3 | Non-Inverting Input (+IN) | Differential input node; identical impedance/capacitance to –IN; requires matched trace routing for optimal CMRR. |
| 4 | Negative Supply (–VS) | Ground reference for single-supply operation or negative rail in dual-supply; decoupling capacitor required within 1 cm. |
| 5 | Disable (DISABLE) | Active-low digital control; pulls output to high-impedance state; logic threshold referenced to –VS (–VS + 0.8 V max low). |
| 6 | Positive Supply (+VS) | Primary power rail; supports 2.7–12 V; requires local 0.1 µF ceramic + 4.7 µF tantalum decoupling per supply pin. |
| 7 | Output (VOUT) | Low-impedance buffered output; drives ≥1 kΩ loads directly; stable with ≤15 pF capacitive load (30% overshoot spec). |
| 8 | No Connect (NC) | Internally unconnected; no electrical function; may be grounded for mechanical stability if needed. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O with 200 mV beyond-rail input | Enables direct interfacing to 0–3.3 V or 0–5 V sensors and ADCs without external biasing or level shifters. |
| 125 MHz bandwidth at 1.3 mA supply current | Delivers RF-grade small-signal response while consuming <6.5 mW - ideal for space-constrained, thermally sensitive designs. |
| 80 ns 0.1% settling time | Meets timing budget for 10+ bit SAR ADCs sampling at 10 MSPS, reducing aperture uncertainty and code errors. |
| Active disable with 150 µA standby current | Supports dynamic power gating in multi-channel systems, extending battery life without sacrificing wake-up latency. |
| Specified over –40°C to +125°C | Validated for automotive safety vision modules and industrial edge sensors requiring extended temperature reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4891-1ARJZ-R7 | Lower bandwidth (220 MHz), higher supply current (6.5 mA), SC70-6 package, no disable pin. | Better for ultra-high-speed, AC-coupled signal chains where power is secondary; unsuitable for power-gated systems. | Select ADA4891-1ARJZ-R7 when bandwidth >150 MHz is mandatory and disable functionality is unnecessary. |
| OPA355UA | Lower slew rate (45 V/µs), narrower bandwidth (200 MHz at G = –1 only), no disable pin, SOIC-8 package. | Optimized for low-noise, precision DC-coupled applications; lacks beyond-rail input and active disable. | Select OPA355UA when input offset voltage (<2 mV typ) and voltage noise (6.5 nV/√Hz) are prioritized over disable control and rail extension. |
Compared with ADA4891-1ARJZ-R7 and OPA355UA, AD8029ARZ-REEL uniquely balances 125 MHz bandwidth, 1.3 mA quiescent current, rail-to-rail I/O with 200 mV beyond-rail tolerance, and active disable - making it the only choice for battery-operated, multiplexed, wideband analog front-ends requiring thermal and power efficiency.

FAQ
What is the maximum supply voltage for AD8029ARZ-REEL?
The absolute maximum supply voltage for AD8029ARZ-REEL is 12.6 V, but the recommended operating range is 2.7 V to 12 V. Operation above 12 V risks permanent damage. At 12 V, quiescent current remains ~1.4 mA, and output swing is specified to within 40 mV of rails with 1 kΩ load - enabling direct interface to 12 V ADCs or legacy industrial sensors.
Does AD8029ARZ-REEL support true single-supply operation?
Yes, AD8029ARZ-REEL supports true single-supply operation with rail-to-rail input and output. At +5 V supply, its input common-mode range extends from –0.2 V to +5.2 V (200 mV beyond rails), and output swings from –VS + 0.17 V to +VS – 0.17 V (i.e., 0.17 V to 4.83 V). This eliminates external bias networks in 3.3 V or 5 V systems.
What is the function of the DISABLE pin on AD8029ARZ-REEL?
Pin 5 (DISABLE) is an active-low digital control that places AD8029ARZ-REEL into high-impedance output state with quiescent current reduced to 150–200 µA. Turn-on time is <95 ns; turn-off time is <165 ns. Off-isolation exceeds –55 dB at 1 MHz, making it suitable for multiplexed signal paths and power-gated subsystems.
Can AD8029ARZ-REEL drive heavy capacitive loads?
AD8029ARZ-REEL is stable with ≤15 pF capacitive load (30% overshoot limit) at +5 V supply. Driving >20 pF requires external series resistance (e.g., 10–50 Ω) at the output to maintain phase margin. Its 125 MHz bandwidth and 60 V/µs slew rate make it unsuitable for direct LCD or cable-driving applications without isolation or buffering.
Is AD8029ARZ-REEL qualified for automotive applications?
The AD8029ARZ-REEL itself is not automotive-qualified; however, the AD8029 family includes the AD8029W variant (not this part number), which is AEC-Q100 Grade 1 qualified (–40°C to +125°C) and specified for automotive safety and vision systems. AD8029ARZ-REEL is rated for the extended industrial range (–40°C to +125°C) and widely used in non-safety-critical automotive subsystems.
