Product details
Overview
AD8036ARZ-REEL7 from Analog Devices is a unity-gain-stable, voltage-feedback clamp amplifier optimized for high-fidelity signal conditioning in ADC buffering and IF/RF signal processing. It delivers 240 MHz small-signal bandwidth, 195 MHz large-signal bandwidth (4 Vp-p), –72 dBc third-harmonic distortion at 20 MHz (RL = 500 Ω), 3 mV typical clamp error, and 1.5 ns overdrive recovery - enabling precise clamping of fast video, imaging, and communications waveforms.
For engineers reviewing the AD8036ARZ-REEL7 datasheet, AD8036ARZ-REEL7 pinout, AD8036ARZ-REEL7 application, or AD8036ARZ-REEL7 equivalent, key selection criteria include its input-clamp architecture (VH/VL pins supporting up to 240 MHz clamp input bandwidth), ±3.9 V clamp voltage range, 1500 V/µs slew rate, and SOIC-8 industrial-grade packaging with 7" tape-and-reel delivery.
Technical Context
The AD8036ARZ-REEL7 implements a patented CLAMPIN™ input clamp architecture that places clamp control directly at the amplifier's input stage - unlike traditional output clamps - enabling accurate, low-distortion limiting without open-loop operation or output impedance degradation. Its voltage-feedback topology provides stable 65° phase margin and constant gain-bandwidth product behavior across closed-loop gains.
Clamp functionality operates exclusively in noninverting configurations, where VH and VL serve as active clamp level inputs (not just DC references): signals up to 240 MHz can be applied to these pins, and clamp thresholds are set independently within the output voltage range (provided VH > VL). The device achieves 10× better clamp accuracy than conventional output-clamp amplifiers, with minimal nonlinear region (≤100 mV) and 1.5 ns recovery from 2× overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 240 MHz @ G = +1, VOUT ≤ 0.4 Vp-p: supports wideband baseband and IF signal buffering without attenuation. |
| Large-signal BW | 195 MHz @ 4 Vp-p: maintains fidelity for high-amplitude video, radar, or imaging signals. |
| Clamp error | ±3 mV typ @ 2× overdrive: ensures precise amplitude limiting critical for ADC front-end protection. |
| Slew rate | 1500 V/µs: enables faithful reproduction of fast edges in pulse and modulated waveforms. |
| Settling time | 16 ns to 0.01% (2 V step): guarantees rapid stabilization after transients in sampling systems. |
| Input noise | 4.5 nV/√Hz @ 1–200 MHz: preserves SNR in low-level analog signal chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar clamp amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8037ARZ-REEL7 | Gain-stable at AV ≥ +2; higher small-signal BW (270 MHz); lower large-signal BW (190 MHz @ 3.5 Vp-p); different clamp input bias (±50 µA). | Requires minimum gain of +2; unsuitable for unity-gain buffers; preferred for fixed-gain IF amplification with tighter gain tolerance. | Select AD8037ARZ-REEL7 when closed-loop gain ≥ +2 is acceptable and higher small-signal bandwidth is prioritized over unity-gain flexibility. |
| LMH6723MA/NOPB | No integrated clamp inputs; 320 MHz GBW; 2000 V/µs slew; higher quiescent current (25 mA); no VH/VL pins or clamp recovery spec. | Requires external clamping circuitry (diodes, op-amps); adds board area, latency, and distortion; not drop-in for clamp-specific designs. | Choose LMH6723MA/NOPB only when clamp functionality is implemented externally and maximum speed outweighs integration benefits. |
Compared with AD8037ARZ-REEL7 and LMH6723MA/NOPB, the AD8036ARZ-REEL7 uniquely combines unity-gain stability, integrated high-speed input clamping, and sub-2 ns recovery - making it irreplaceable for compact, high-accuracy ADC front-ends and dynamic amplitude control where pin count, layout simplicity, and deterministic clamping behavior are critical.

FAQ
What is the operating temperature range for the AD8036ARZ-REEL7?
The AD8036ARZ-REEL7 is rated for industrial operation from –40°C to +85°C, as confirmed in the Analog Devices ordering guide. This range applies to the SOIC-8 package variant (model suffix "AR") and is validated across all electrical specifications including clamp accuracy, bandwidth, and distortion performance.
Does the AD8036ARZ-REEL7 require external compensation for unity-gain stability?
No, the AD8036ARZ-REEL7 is internally compensated for unity-gain stability (AV = +1). The datasheet explicitly states "The AD8036 is unity gain stable," and recommends RF = 140 Ω for optimal transient response and bandwidth in noninverting configurations - no additional capacitors or feedback networks are needed.
Can the VH and VL pins accept AC signals, or are they DC-only references?
The VH and VL pins on the AD8036ARZ-REEL7 accept both DC and AC signals up to 240 MHz (–3 dB), as specified under "Clamp Input Bandwidth" in the Electrical Characteristics table. This enables dynamic clamp level control - for example, applying a modulating signal to VH while holding VL at DC to implement amplitude modulation or envelope tracking.
What is the maximum allowable differential input voltage for the AD8036ARZ-REEL7?
The absolute maximum differential input voltage for the AD8036ARZ-REEL7 is ±1.2 V, as stated in the Absolute Maximum Ratings table. Exceeding this may cause permanent damage. For reliable operation, input common-mode voltage must stay within ±2.5 V, and clamp inputs (VH/VL) must satisfy |VH – VIN| ≤ 6.3 V and |VL – VIN| ≤ 6.3 V.
Is the AD8036ARZ-REEL7 pin-compatible with the AD8036ARZ or AD8036AR-REEL?
Yes, the AD8036ARZ-REEL7 shares identical SOIC-8 (SO-8) pinout, footprint, and electrical characteristics with AD8036ARZ and AD8036AR-REEL. The suffix "-REEL7" denotes packaging in a 7-inch tape-and-reel format; all three variants use the same die, bond wire configuration, and terminal assignments per the functional block diagram and metalization photo.
