Product details
Overview
AD8027ARZ-REEL from Analog Devices is a single-channel, rail-to-rail input/output high-speed voltage feedback amplifier optimized for low-distortion signal conditioning in precision analog front-ends. It delivers 190 MHz −3 dB bandwidth (G = +1), 100 V/µs slew rate, 120 dBc SFDR at 1 MHz, 4.3 nV/√Hz input voltage noise, and operates from 2.7 V to 12 V supplies - enabling use as an ADC driver in 16-bit data acquisition systems with ±5 V or single 5 V supplies.
For engineers reviewing the AD8027ARZ-REEL datasheet, AD8027ARZ-REEL pinout, AD8027ARZ-REEL application, or AD8027ARZ-REEL equivalent, key selection considerations include its selectable input crossover threshold via DISABLE/SELECT pin, no phase reversal behavior beyond rails, 6.5 mA quiescent current per amplifier, and SOIC-8 packaging suitable for space-constrained industrial instrumentation and video signal paths.
Technical Context
The AD8027ARZ-REEL employs a complementary bipolar XFCB process to achieve rail-to-rail input operation across ±5 V, +5 V, or +3 V supplies while maintaining constant transconductance across PNP/NPN input pair transitions. Its DISABLE/SELECT pin controls both power-down mode and crossover point selection - shifting the NPN/PNP switching threshold to either rail to minimize distortion in high-side or low-side common-mode applications.
This amplifier features intrinsically low crossover distortion without external trimming, supports capacitive loads up to 20 pF, recovers from overdrive in 40/45 ns (rising/falling), and maintains >90 dB CMRR and >90 dB PSRR across audio to RF frequencies - making it suitable for DC-coupled buffer stages where offset stability and wideband linearity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 190 MHz at G = +1, ±5 V supply - enables full-power response through UHF band for video and IF signal chains. |
| Slew Rate | 100 V/µs (G = −1) - supports clean 2 V step response with ≤35 ns settling to 0.1% in gain-of-two configurations. |
| SFDR | 120 dBc at 1 MHz, 2 Vp-p - ensures <0.0001% spurious content in 16-bit ADC driver applications. |
| Input Voltage Noise | 4.3 nV/√Hz at 100 kHz - preserves SNR in low-level sensor signal amplification before digitization. |
| Supply Range | 2.7 V to 12 V - allows direct interface with 3.3 V, 5 V, and ±5 V systems without level-shifting circuitry. |
| Quiescent Current | 6.5 mA per amplifier - balances speed and power for battery-aware portable instrumentation. |
| Input Offset Voltage | 900 µV maximum - enables accurate DC-coupled gain stages in precision measurement front-ends. |
Pinout & Package
AD8027ARZ-REEL is packaged in an 8-lead SOIC (Small Outline Integrated Circuit) with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). The package is RoHS-compliant, halogen-free, and rated for operation from −40°C to +125°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | DNC | Do Not Connect - internal test pads; must remain unconnected on PCB to avoid performance degradation. |
| 2 | −IN | Inverting input - accepts differential or single-ended signals; rail-to-rail common-mode range extends 200 mV beyond supply rails. |
| 3 | +IN | Non-inverting input - matched impedance to −IN; used for unity-gain buffers or active filters requiring high CMRR. |
| 4 | −VS | Negative supply terminal - required for dual-supply operation; tied to ground in single-supply configurations. |
| 6 | VOUT | Amplifier output - rail-to-rail swing (±4.94 V typical on ±5 V) drives 1 kΩ loads or ADC inputs directly. |
| 7 | +VS | Positive supply terminal - accepts 2.7–12 V; bypassing with 0.1 µF ceramic capacitor near pin is mandatory. |
| 8 | DISABLE/SELECT | Multi-function control pin - high = NPN-dominant input mode; open/tristate = PNP-dominant mode; low = shutdown (370 µA IQ). |
Key Features
| Feature | Design Value |
|---|---|
| Selectably adjustable input crossover threshold | Enables optimization of distortion vs. common-mode voltage by choosing dominant NPN or PNP input pair via DISABLE/SELECT pin voltage. |
| No phase reversal under overvoltage | Operates safely with inputs up to |VS| + 200 mV - eliminates latch-up risk in sensor interfaces with transient overvoltage. |
| Rail-to-rail input and output swing | Supports full dynamic range utilization in low-voltage systems (e.g., 3 V ADC drivers) without headroom loss. |
| Low power-down current | Reduces quiescent supply current to 370 µA (typical) when DISABLE/SELECT is pulled low - ideal for duty-cycled signal paths. |
| Wideband noise performance | 4.3 nV/√Hz voltage noise + 1.6 pA/√Hz current noise enables high-fidelity amplification of low-amplitude, wideband signals. |
Applications
| ADC Driver | Professional Video Amplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-1ARMZ-R7 | Lower noise (1 nV/√Hz), lower IQ (3.5 mA), but narrower bandwidth (100 MHz) and no DISABLE/SELECT crossover control. | Better for ultra-low-noise photodiode preamps; unsuitable where input common-mode exceeds 1.5 V on 3.3 V supply. | Choose ADA4897-1 when noise dominates over bandwidth and crossover flexibility is unnecessary. |
| LMH6629MA/NOPB | Higher slew rate (1300 V/µs), higher IQ (12.5 mA), no rail-to-rail input, fixed crossover, no power-down. | Preferred for pulse amplification in LIDAR; incompatible with DC-coupled sensor interfaces requiring rail-to-rail input. | Choose LMH6629 when extreme slew rate is required and supply headroom permits non-rail-to-rail input operation. |
Compared with ADA4897-1ARMZ-R7 and LMH6629MA/NOPB, AD8027ARZ-REEL uniquely combines 190 MHz bandwidth, selectable crossover, rail-to-rail I/O, and 6.5 mA quiescent current - making it the only option supporting both high-fidelity ADC driving and low-voltage instrumentation without design trade-offs.

FAQ
What is the maximum supply voltage for AD8027ARZ-REEL?
The absolute maximum supply voltage for AD8027ARZ-REEL is 12.6 V, but the recommended operating range is 2.7 V to 12 V. Operation at 12 V is supported across the full −40°C to +125°C temperature range, with specified performance including 138 MHz −3 dB bandwidth and 900 µV max input offset voltage. Exceeding 12.6 V risks permanent damage per Absolute Maximum Ratings Table 4.
Does AD8027ARZ-REEL support single-supply operation?
Yes, AD8027ARZ-REEL supports true single-supply operation down to 2.7 V. With −VS grounded, the input common-mode range extends from −0.2 V to +5.2 V (at VS = 5 V), and output swings from 0.08 V to 4.92 V - enabling direct interfacing with 5 V or 3.3 V ADCs without level-shifting circuitry. The DISABLE/SELECT pin functions identically in single- and dual-supply modes.
How does the DISABLE/SELECT pin affect AD8027ARZ-REEL performance?
The DISABLE/SELECT pin on AD8027ARZ-REEL serves two roles: pulling it low enables power-down mode (IQ drops to 370 µA), while leaving it open selects PNP-dominant input operation and pulling it high selects NPN-dominant operation - shifting the input crossover threshold to optimize SFDR for high- or low-side common-mode signals. This feature is unique to the AD8027/AD8028 family and directly impacts distortion at specific input voltages.
What is the capacitive load drive capability of AD8027ARZ-REEL?
AD8027ARZ-REEL is characterized to drive up to 20 pF capacitive loads with ≤30% overshoot in unity-gain configuration, as specified in Tables 1–3. For heavier loads (e.g., ADC input capacitance + PCB trace), a small series resistor (10–22 Ω) at the output is recommended to maintain stability. Performance degrades above 20 pF, with increased settling time and potential peaking observed beyond 30 pF.
Is AD8027ARZ-REEL pin-compatible with other members of the AD8027/AD8028 family?
AD8027ARZ-REEL (SOIC-8) shares identical pinout with AD8027AR-REEL and AD8027ARM-REEL (MSOP-8), but is not pin-compatible with AD8028 variants (dual-channel) or SOT-23 packages. Pin 1 and 5 are DNC in all SOIC-8 versions; pins 2–4, 6–8 retain identical functions. Always verify package outline and thermal pad presence before PCB layout reuse.
