Product details
Overview
AD8029AKS-REEL7 from Analog Devices is a single-channel, rail-to-rail input/output high-speed voltage feedback amplifier optimized for low-power, high-bandwidth signal conditioning. It delivers 125 MHz –3 dB bandwidth (G = +1), 60 V/µs slew rate, 80 ns settling to 0.1%, and operates from 2.7 V to 12 V supply with only 1.3 mA quiescent current per amplifier. It is used in A-to-D drivers, battery-powered instrumentation, and automotive vision systems.
For engineers reviewing the AD8029AKS-REEL7 datasheet, AD8029AKS-REEL7 pinout, AD8029AKS-REEL7 application, or AD8029AKS-REEL7 equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for design-in and sourcing decisions.
Technical Context
The AD8029AKS-REEL7 uses Analog Devices' proprietary XFCB process to achieve high speed and precision at low power. Its voltage-feedback architecture supports stable operation with gain ≥ +1, exhibits no phase reversal when inputs extend 200 mV beyond rails, and maintains rail-to-rail output swing within 40 mV of each supply rail under 1 kΩ load.
It features an active disable pin enabling low-power standby mode (quiescent current drops to 140–200 µA), fast turn-on/turn-off times (85 ns / 150 ns), and robust capacitive load drive up to 20 pF (at ±5 V). Input stage combines PNP/NPN transistor pairs for wide common-mode range (–0.2 V to +5.2 V at +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 high-fidelity signal amplification up to video and data-acquisition frequencies. |
| Slew Rate | 60 V/µs (typical); supports clean reproduction of fast transient signals without slew-induced distortion. |
| Settling Time | 80 ns to 0.1% (G = +2, 2 V step); critical for multiplexed ADC driver applications requiring rapid channel switching. |
| Supply Range | 2.7 V to 12 V single or dual supply; allows direct integration into 3.3 V, 5 V, and ±5 V systems without level-shifting. |
| Quiescent Current | 1.3 mA per amplifier (typical at +5 V); enables >100-hour operation on coin-cell batteries in portable instrumentation. |
| Input Offset Voltage | ≤6 mV max (25°C); ensures DC accuracy in precision buffer and sensor interface circuits. |
| Output Swing | Within 170 mV of rails (RL = 1 kΩ, +5 V supply); maximizes dynamic range in single-supply data converters. |
Pinout & Package
AD8029AKS-REEL7 is packaged in SC70-6 (KS), a 6-pin ultra-small outline package measuring 2.0 mm × 1.25 mm × 0.9 mm. Pin 1 is marked with a dot; pin count and layout match JEDEC MO-203-AB standard.
| 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; accepts signals up to 200 mV beyond supply rails without phase reversal. |
| 3 (+IN) | Non-Inverting Input | Differential input node; high-impedance (6 MΩ) with 2 pF capacitance; requires matched trace routing. |
| 4 (–VS) | Negative Supply | Ground reference in single-supply operation; connects to system GND or negative rail in dual-supply configs. |
| 5 (DISABLE) | Active-Low Enable | Pulls output to high-impedance state when logic low; reduces supply current to ≤200 µA for power gating. |
| 6 (+VS) | Positive Supply | Primary power input; bypassing with 0.1 µF ceramic capacitor near pin is mandatory for stability. |
| VOUT | Output | Rail-to-rail output capable of driving 1 kΩ loads to within 170 mV of rails; supports 20 pF capacitive loads. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends –0.2 V to +5.2 V (at +5 V supply); output swings to within 170 mV of rails - preserves full signal headroom in low-voltage systems. |
| Low Power High Speed | 125 MHz bandwidth with only 1.3 mA supply current - achieves performance previously requiring >5× power in comparable amplifiers. |
| Disable Function | Active-low DISABLE pin reduces quiescent current to 140–200 µA and isolates output by –55 dB at 1 MHz - enables dynamic power management in multi-channel systems. |
| Wide Supply Range | Operates from 2.7 V to 12 V - supports direct interface with Li-ion, USB, and industrial 5 V/12 V rails without regulators. |
| No Phase Reversal | Input stage remains linear even when driven 200 mV beyond either supply rail - eliminates latch-up risk in overvoltage transients. |
Applications
| Automotive Vision Systems | A-to-D Converter Drivers |

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 |
|---|---|---|---|
| ADA4891-1AKSZ-R7 | Lower bandwidth (220 MHz), higher supply current (6.5 mA), same SC70-6 package, no disable pin. | Better for wideband AC-coupled applications; unsuitable where dynamic power gating is required. | Select if bandwidth >125 MHz is needed and disable functionality is not required. |
| OPA355DBVR | 150 MHz bandwidth, 4.9 mA supply current, SOT23-6 package, no disable pin, higher input bias current (±5 pA). | Higher power consumption limits battery life; better for high-precision DC-coupled paths with lower noise floor. | Select for applications prioritizing bandwidth and voltage noise over quiescent power. |
Compared with ADA4891-1AKSZ-R7 and OPA355DBVR, AD8029AKS-REEL7 uniquely balances 125 MHz bandwidth, 1.3 mA supply current, and integrated disable control in SC70-6 - making it optimal for space-constrained, battery-sensitive, and dynamically powered systems.

FAQ
What is the maximum operating temperature for AD8029AKS-REEL7?
The AD8029AKS-REEL7 is rated for operation from –40°C to +125°C, meeting extended industrial temperature requirements. This rating is confirmed in the Absolute Maximum Ratings table and applies across all specified electrical performance conditions, making AD8029AKS-REEL7 suitable for under-hood automotive and industrial environments.
Does AD8029AKS-REEL7 support single-supply operation?
Yes, AD8029AKS-REEL7 fully supports true single-supply operation from 2.7 V to 12 V. Its rail-to-rail input extends 200 mV beyond the negative rail (e.g., down to –0.2 V at +5 V supply), and its output swings to within 170 mV of both rails under 1 kΩ load - enabling direct interfacing with single-supply ADCs and microcontrollers.
What is the function of the DISABLE pin on AD8029AKS-REEL7?
The DISABLE pin on AD8029AKS-REEL7 is an active-low control that places the amplifier output in high-impedance state and reduces quiescent current to 140–200 µA. When asserted, it provides –55 dB off-isolation at 1 MHz and enables fast turn-on (85 ns) and turn-off (150 ns) for dynamic power management in multi-amplifier systems.
Can AD8029AKS-REEL7 drive capacitive loads?
Yes, AD8029AKS-REEL7 can drive up to 20 pF capacitive load with ≤30% overshoot when supplied at ±5 V. At +5 V supply, it supports up to 15 pF, and at +3 V, up to 10 pF. Layout best practices - including short traces, local bypassing, and avoiding long unterminated lines - are essential to maintain stability with capacitive loads.
Is AD8029AKS-REEL7 pin-compatible with other members of the AD8029/AD8030/AD8040 family?
No, AD8029AKS-REEL7 in SC70-6 is not pin-compatible with SOIC-8, SOT23-8, SOIC-14, or TSSOP-14 variants of the AD8029 family. The SC70-6 pinout (6-pin, with NC, –IN, +IN, –VS, DISABLE, +VS) differs fundamentally from 8-pin and 14-pin packages, which include additional pins for second/third/fourth amplifiers or different disable configurations.
