Product details
Overview
AD8029ARZ-REEL7 from Analog Devices is a single-channel, rail-to-rail input/output high-speed voltage feedback amplifier optimized for low-power, high-fidelity signal conditioning. 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 supplies. Its 1.3 mA quiescent current per amplifier and true single-supply operation make it ideal for A-to-D drivers in battery-powered instrumentation and automotive vision systems.
For engineers reviewing the AD8029ARZ-REEL7 datasheet, AD8029ARZ-REEL7 pinout, AD8029ARZ-REEL7 application, or AD8029ARZ-REEL7 equivalent, key selection criteria include its disable pin functionality, rail-to-rail dynamic range (within 40 mV of rails), low distortion (–72 dBc SFDR at 1 MHz), and SOIC-8 package compatibility with space-constrained PCB layouts.
Technical Context
The AD8029ARZ-REEL7 employs Analog Devices' proprietary XFCB process to achieve high speed and precision at low power. Its input stage supports common-mode voltages extending 200 mV beyond either supply rail without phase reversal, while the output stage drives within 40 mV of both rails under 1 kΩ load. The integrated DISABLE pin enables fast power gating with 85 ns turn-on and 150 ns turn-off times.
This amplifier operates stably across ±5 V, +5 V, and +3 V supplies, maintaining ≥112 MHz small-signal bandwidth and ≤6 mV input offset voltage over –40°C to +125°C. Its 2 pF input capacitance and 6 MΩ input resistance support high-impedance sensor interfacing, and its 1.1 pA/√Hz input current noise minimizes error in high-source-impedance configurations.
Key Specifications

Pinout & Package
AD8029ARZ-REEL7 is housed in an 8-lead SOIC (R) package (JEDEC MS-012AA), with exposed pad not electrically connected. Thermal resistance θJA is 125°C/W on a 4-layer JEDEC board.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally unused; must be left floating or tied to ground for mechanical stability only. |
| 2 | Inverting Input (–IN) | Differential input node; accepts signals up to 200 mV beyond either supply rail without phase reversal. |
| 3 | Noninverting Input (+IN) | Differential input node; high-impedance (6 MΩ) interface for sensors or filter outputs. |
| 4 | Negative Supply (–VS) | Ground reference in single-supply mode; connects to system ground or negative rail in dual-supply operation. |
| 5 | Disable (DISABLE) | Active-low digital control; pulls output to high-impedance state when logic low (≤ –VS + 0.8 V). |
| 6 | Positive Supply (+VS) | Power input; supports 2.7 V to 12 V operation; requires local 0.1 µF ceramic bypass capacitor. |

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 (6-pin), no disable pin. | Preferred where higher speed is critical and board area is constrained; unsuitable for power-gated systems. | Select ADA4891-1ARJZ-R7 for >150 MSPS ADC drivers; avoid when <2 mA quiescent current or disable functionality is required. |
| OPA355UA | Lower bandwidth (200 MHz), higher offset (8 mV max), SOIC-8 package, no disable pin, 5.5 mA supply current. | Better DC precision than AD8029ARZ-REEL7 but consumes >4× more power; lacks rail-to-rail input beyond rails. | Choose OPA355UA for DC-critical sensor amplification; avoid for battery-powered high-speed buffering requiring low IQ and wide input range. |
Compared with ADA4891-1ARJZ-R7 and OPA355UA, AD8029ARZ-REEL7 uniquely balances 125 MHz bandwidth, 1.3 mA quiescent current, rail-to-rail input beyond rails, and integrated disable control - making it optimal for power-aware, high-fidelity signal chains where component count and thermal budget are constrained.

FAQ
What is the maximum supply voltage for AD8029ARZ-REEL7?
The absolute maximum supply voltage for AD8029ARZ-REEL7 is 12.6 V, but the recommended operating range is 2.7 V to 12 V. Operation above 12 V risks permanent damage; sustained use at 12 V is permissible only with adequate thermal management, as junction temperature must remain below 150°C. The device is fully specified from ±5 V, +5 V, and +3 V supplies.
Does AD8029ARZ-REEL7 support true rail-to-rail input beyond the supply rails?
Yes, AD8029ARZ-REEL7 supports input common-mode voltages extending 200 mV beyond either supply rail - e.g., –0.2 V to +5.2 V on a +5 V supply - without phase reversal or clipping. This capability is confirmed in the General Description and Table 1–3 under "Input Common-Mode Voltage Range", enabling direct interfacing with overvoltage-tolerant sensors and legacy analog sources.
What is the purpose of the DISABLE pin on AD8029ARZ-REEL7?
The DISABLE pin on AD8029ARZ-REEL7 is an active-low digital control that places the output in high-impedance state when driven low (≤ –VS + 0.8 V). It achieves 85 ns turn-on and 150 ns turn-off times, reducing quiescent current to 140–200 µA in disabled mode. This feature is essential for power-gated signal chains, such as those synchronized to ADC sampling clocks or low-duty-cycle sensor readouts.
Can AD8029ARZ-REEL7 drive heavy capacitive loads?
AD8029ARZ-REEL7 is stable with ≤15 pF capacitive load under +5 V supply (Table 2), and ≤10 pF under +3 V (Table 3). Driving larger loads (e.g., >20 pF) risks peaking or oscillation unless isolated with a series resistor (≥10 Ω) or compensated per Figure 28 in the datasheet. Its 15 pF limit reflects design trade-offs between speed, power, and stability - not a limitation of layout alone.
Is AD8029ARZ-REEL7 qualified for automotive applications?
No - AD8029ARZ-REEL7 is the commercial-grade variant. The automotive-qualified version is AD8029WARMZ (SOIC-8, AEC-Q100 Grade 1, –40°C to +125°C). While AD8029ARZ-REEL7 shares identical electrical specs and operates across –40°C to +125°C, it lacks AEC-Q100 certification, traceability documentation, and automotive-specific reliability testing required for safety-critical vehicle systems.
