Product details
Overview
AD8029ARZ from Analog Devices is a single-channel, rail-to-rail input/output voltage feedback operational amplifier optimized for high-speed, low-power 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%, with 1.3 mA quiescent current and operation from 2.7 V to 12 V supplies. It is widely used as an A-to-D driver in battery-powered instrumentation and automotive vision systems.
For engineers reviewing the AD8029ARZ datasheet, AD8029ARZ pinout, AD8029ARZ application, or AD8029ARZ equivalent, key selection considerations include its disable functionality, rail-to-rail swing within 40 mV of rails, no phase reversal beyond rails, ±5 V/±2.5 V/+5 V/+3 V supply compatibility, and SOIC-8 packaging with verified thermal performance up to +125°C.
Technical Context
The AD8029ARZ employs Analog Devices' proprietary XFCB process to achieve high-speed performance at low power, enabling true single-supply operation with rail-to-rail input range extending 200 mV beyond both supply rails and output swing within 40 mV of each rail. Its input stage avoids phase reversal under overdrive, and its output stage supports fast overdrive recovery (55/45 ns rising/falling).
It features an active-disable function (pin 5) that reduces quiescent current to 140–200 µA while providing –55 dB off-isolation at 1 MHz. The amplifier maintains stable performance across –40°C to +125°C and supports capacitive loads up to 20 pF (with 30% overshoot) under ±5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| –3 dB Bandwidth | 125 MHz at G = +1, VO = 0.1 V p-p (±5 V supply); enables wideband signal amplification without gain peaking |
| Slew Rate | 60 V/µs (typical); supports clean reproduction of fast transient signals up to ~10 MHz full-power sine waves |
| Settling Time to 0.1% | 80 ns (G = +2, 2 V step); critical for precision sampling in ADC front-ends requiring minimal acquisition delay |
| Input Common-Mode Range | –5.2 V to +5.2 V (±5 V supply); extends 200 mV beyond rails with no phase reversal-enables direct sensing near supply extremes |
| Output Voltage Swing | –VS + 0.22 V to +VS – 0.22 V (RL = 1 kΩ, ±5 V); delivers >95% of full supply dynamic range for maximum SNR in low-voltage systems |
| Quiescent Current | 1.3–1.5 mA per amplifier; allows extended battery life in portable instrumentation without sacrificing speed |
| Disable Current | 140–200 µA (DISABLE = Low); reduces system standby power by >90% while maintaining fast 85 ns turn-on |
Pinout & Package
AD8029ARZ is packaged in an 8-lead SOIC (SOIC-8, package code R), with exposed pad not present. Pin functions are validated per Figure 1 of the AD8029/AD8030/AD8040 Rev. B datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NC | No Connect | Internally unconnected; must be left floating or tied to ground per layout best practice |
| 2 –IN | Inverting Input | Differential input node; high impedance (6 MΩ), low capacitance (2 pF) minimizes high-frequency loading |
| 3 +IN | Non-Inverting Input | Differential input node; rail-to-rail common-mode range supports direct interface to sensors and DACs |
| 4 –VS | Negative Supply | Supports dual-supply (±2.5 V to ±6 V) or single-supply (ground reference) operation |
| 5 DISABLE | Active-Low Enable Control | Pulls amplifier into low-power state (<200 µA); logic-compatible with 0.8 V low / 1.2 V high thresholds |
| 6 +VS | Positive Supply | Accepts 2.7 V to 12 V total supply range; PSRR >73 dB ensures noise immunity in noisy environments |
| 7 VOUT | Amplifier Output | Rail-to-rail capable; drives 1 kΩ load to within 220 mV of rails; stable with ≤20 pF capacitive load |
| 8 NC | No Connect | Internally unconnected; no routing or connection required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O with no phase reversal | Input operates –5.2 V to +5.2 V (±5 V supply); output swings to within 220 mV of rails-preserves signal integrity near supply boundaries |
| Low-power high-speed architecture | 125 MHz bandwidth and 60 V/µs slew rate achieved at only 1.3 mA-enables high-fidelity analog front-ends in energy-constrained designs |
| Integrated disable control | Pin 5 enables hardware-controlled power gating; 85 ns turn-on supports burst-mode signal acquisition |
| Wide supply flexibility | Operates from 2.7 V to 12 V total supply; supports single-supply (e.g., +5 V), split-supply (±5 V), and low-voltage battery systems |
| Automotive-grade variant available | AD8040W is AEC-Q100 qualified; AD8029ARZ shares same core design and extended temperature rating (–40°C to +125°C) |

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 suited for fixed high-speed gain stages where power is secondary; lacks hardware power gating | Select when >200 MHz bandwidth is required and disable functionality is unnecessary |
| OPA355UA | Lower slew rate (45 V/µs), narrower bandwidth (200 MHz), no disable pin, SOIC-8; higher input bias current (±10 pA) | Optimized for low-noise precision rather than ultra-fast settling; less suitable for ADC driving at >5 MSPS | Select when input voltage noise (7 nV/√Hz) is prioritized over settling speed and power efficiency |
Compared with ADA4891-1ARJZ-R7 and OPA355UA, AD8029ARZ uniquely balances 125 MHz bandwidth, 1.3 mA quiescent current, rail-to-rail I/O, and integrated disable-making it optimal for power-sensitive, high-throughput signal chains requiring rapid enable/disable cycling.

FAQ
What supply voltages does the AD8029ARZ support?
The AD8029ARZ operates from a total supply range of 2.7 V to 12 V, supporting single-supply (e.g., +3 V, +5 V), split-supply (±2.5 V, ±5 V), and asymmetric configurations. At +5 V supply, it delivers 120 MHz bandwidth and 55 V/µs slew rate; at ±5 V, bandwidth reaches 125 MHz with 62 V/µs slew rate. All specifications are validated across –40°C to +125°C.
Does the AD8029ARZ have rail-to-rail input and output capability?
Yes, the AD8029ARZ provides true rail-to-rail input and output operation. Its input common-mode range extends 200 mV beyond both supply rails without phase reversal, and its output swings to within 40 mV of each rail (e.g., –VS + 0.04 V to +VS – 0.04 V at RL = 10 kΩ, +3 V supply). This enables full utilization of ADC input ranges and direct interfacing with low-voltage logic.
What is the purpose of the DISABLE pin on the AD8029ARZ?
The DISABLE pin (Pin 5) is an active-low control that places the AD8029ARZ into a low-power standby mode drawing only 140–200 µA. It achieves 85 ns turn-on and 155 ns turn-off times, enabling rapid power cycling in burst-mode systems. Off-isolation exceeds –55 dB at 1 MHz, preventing signal leakage during disabled state-critical for multiplexed or shared-bus architectures.
Can the AD8029ARZ drive capacitive loads?
Yes, the AD8029ARZ is specified to drive up to 20 pF capacitive load with ≤30% overshoot under ±5 V supply. Performance degrades with larger loads: at 10 pF, small-signal bandwidth remains stable; at 20 pF, transient response shows controlled ringing. For >20 pF, external isolation resistor (e.g., 10–50 Ω in series with output) is recommended to maintain stability and settling accuracy.
Is the AD8029ARZ suitable for automotive applications?
The AD8029ARZ itself is not AEC-Q100 qualified, but it shares identical electrical specifications, thermal performance (–40°C to +125°C), and package construction with the automotive-grade AD8040W quad variant. Many automotive Tier 1 suppliers use AD8029ARZ in non-safety-critical vision preprocessing and sensor signal conditioning where full qualification is not mandated-subject to customer-specific validation.
