Product details
Overview
AD8027ARZ-REEL7 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 systems. It delivers 190 MHz −3 dB bandwidth (G = +1), 100 V/µs slew rate, and 120 dBc SFDR at 1 MHz - enabling high-fidelity ADC driving and video signal buffering in ±5 V or single 5 V supply systems.
For engineers reviewing the AD8027ARZ-REEL7 datasheet, AD8027ARZ-REEL7 pinout, AD8027ARZ-REEL7 application, or AD8027ARZ-REEL7 equivalent, this page provides verified technical context, SOIC-8 package mapping, real-world application cards, and two validated alternative op-amps with documented functional trade-offs for ADC driver, video buffer, and instrumentation use cases.
Technical Context
The AD8027ARZ-REEL7 employs a complementary bipolar XFCB process to achieve rail-to-rail input operation beyond the supply rails (±200 mV) without phase reversal, combined with a unique DISABLE/SELECT pin that configures the NPN/PNP input stage crossover threshold - reducing distortion in wide common-mode range applications. Its input stage uses dual differential pairs with laser-trimmed offset and constant transconductance across operating regions.
It features a common-emitter output stage delivering rail-to-rail swing, 120 mA short-circuit current capability, and 40 ns overdrive recovery (rising edge). The device supports power-down mode via the DISABLE/SELECT pin, drawing only 370 µA quiescent current when disabled - critical for portable and power-sensitive instrumentation designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 190 MHz at G = +1, ±5 V supply - supports high-resolution video and fast data acquisition sampling rates. |
| Slew Rate | 100 V/µs (G = −1) - enables clean reproduction of fast transient signals without slewing-induced distortion. |
| SFDR | 120 dBc at 1 MHz, 2 Vp-p - ensures minimal spurious content in sensitive ADC front-ends and RF IF stages. |
| Input Voltage Noise | 4.3 nV/√Hz - preserves signal integrity in low-level sensor amplification and precision gain stages. |
| Input Offset Voltage | 900 µV maximum - maintains DC accuracy in closed-loop configurations requiring <1 mV error budgets. |
| Quiescent Current | 6.5 mA per amplifier - balances speed and power for battery-operated test equipment and portable instrumentation. |
| Supply Range | 2.7 V to 12 V - supports single-supply 3.3 V/5 V and dual-supply ±5 V system integration without redesign. |
Pinout & Package
AD8027ARZ-REEL7 is housed in an 8-lead SOIC (Small Outline Integrated Circuit) package, RoHS-compliant and rated for −40°C to +125°C operation. Pin 1 and Pin 5 are DNC (Do Not Connect); the device uses a single-amplifier topology with dedicated input, output, and supply terminals plus the multifunction DISABLE/SELECT control pin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 2 (−IN) | Inverting Input | Accepts differential or single-ended signals; part of rail-to-rail input stage with PNP/NPN pair selection. |
| Pin 3 (+IN) | Non-Inverting Input | Supports common-mode voltages from −5.2 V to +5.2 V (±5 V supply); no phase reversal beyond rails. |
| Pin 4 (−VS) | Negative Supply | Connects to ground or negative rail; enables true dual-supply operation down to ±1.35 V. |
| Pin 6 (VOUT) | Amplifier Output | Rail-to-rail swing (−4.94 V to +4.94 V on ±5 V); drives 1 kΩ loads with <0.1% settling in 35 ns. |
| Pin 7 (+VS) | Positive Supply | Accepts up to +12 V; PSRR >90 dB minimizes supply noise coupling into signal path. |
| Pin 8 (DISABLE/SELECT) | Power-Down & Crossover Control | Pulling low disables amplifier (370 µA IQ); floating or high selects NPN-dominant input mode for high-side signals. |
Key Features
| Feature | Design Value |
|---|---|
| Selectably configurable input crossover threshold | DISABLE/SELECT pin shifts NPN/PNP transition point to optimize distortion performance for high- or low-side common-mode inputs. |
| No phase reversal over full input range | Operates safely with inputs up to |VS| + 200 mV - eliminates latch-up risk in overvoltage monitoring circuits. |
| Low 1.6 pA/√Hz input current noise | Minimizes Johnson-Nyquist noise contribution in high-impedance sensor interfaces (e.g., photodiode transimpedance amps). |
| 100 V/µs slew rate with 190 MHz bandwidth | Enables unity-gain stable operation while preserving fidelity for 10–20 ns rise time pulses in oscilloscope front-ends. |
| 40 ns overdrive recovery (rising edge) | Recovers cleanly after saturation - essential for pulse amplification and multiplexed signal paths in automated test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-1ARMZ-R7 | Lower noise (1 nV/√Hz), lower IQ (1.2 mA), but narrower bandwidth (100 MHz) and no DISABLE/SELECT pin. | Better for ultra-low-noise sensor preamps; unsuitable where input crossover control or power-down is required. | Choose ADA4897-1ARMZ-R7 when noise dominates design priority and power-down is unnecessary. |
| LMH6629MA/NOPB | Higher slew rate (1300 V/µs), wider bandwidth (1.5 GHz), but higher IQ (12.5 mA) and no rail-to-rail input. | Preferred for GHz-range pulse amplification; cannot accept inputs near supply rails like AD8027ARZ-REEL7. | Choose LMH6629MA/NOPB for ultrafast pulse shaping where input common-mode range is constrained by external biasing. |
Compared with ADA4897-1ARMZ-R7 and LMH6629MA/NOPB, AD8027ARZ-REEL7 uniquely balances 190 MHz bandwidth, rail-to-rail input/output, selectable crossover, and 6.5 mA quiescent current - making it optimal for portable instrumentation and mixed-signal systems needing both precision and speed without sacrificing supply flexibility.

FAQ
What is the maximum supply voltage for AD8027ARZ-REEL7?
The absolute maximum supply voltage for AD8027ARZ-REEL7 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 typical quiescent current of 8.5 mA and −3 dB bandwidth of 138 MHz (G = +1, VOUT = 0.2 Vp-p). Exceeding 12.6 V risks permanent damage per Absolute Maximum Ratings Table 4.
Does AD8027ARZ-REEL7 support single-supply operation?
Yes, AD8027ARZ-REEL7 supports true single-supply operation from 2.7 V to 12 V. At 3 V supply, its input common-mode range extends from −0.2 V to +3.2 V and output swing reaches 0.04 V to 2.96 V - enabling direct interfacing with 3.3 V logic and sensors without level-shifting circuitry. The rail-to-rail input stage operates 200 mV beyond either rail, eliminating phase reversal issues.
How does the DISABLE/SELECT pin function in AD8027ARZ-REEL7?
In AD8027ARZ-REEL7, the DISABLE/SELECT pin serves dual functions: pulling it low (<0.4 V) places the amplifier in power-down mode (IQ = 370 µA), while leaving it open or applying >2.0 V selects NPN-dominant input operation - shifting the crossover threshold toward the positive rail for improved distortion performance with high-side common-mode signals. Tristate operation defaults to PNP-dominant mode.
What is the small-signal settling time specification for AD8027ARZ-REEL7?
AD8027ARZ-REEL7 achieves 35 ns settling time to 0.1% for a 2 V step response under G = +2, ±5 V supply, and 1 kΩ load conditions. This value is measured with VOUT transitioning between ±2.5 V levels and reflects the combined effect of bandwidth, slew rate, and output stage linearity - critical for multiplexed data acquisition systems requiring rapid channel switching.
Is AD8027ARZ-REEL7 pin-compatible with other members of the AD8027/AD8028 family?
AD8027ARZ-REEL7 is pin-compatible only with other AD8027 variants in the same 8-lead SOIC package (e.g., AD8027ARZ), but not with AD8028 (dual-channel) or MSOP/SOT-23 variants. The 8-lead SOIC pinout is fixed per Figure 4 and Table 5: Pins 1/5 are DNC, Pin 2 = −IN, Pin 3 = +IN, Pin 4 = −VS, Pin 6 = VOUT, Pin 7 = +VS, Pin 8 = DISABLE/SELECT - no layout changes required when substituting within the AD8027 SOIC series.
