Product details
Overview
AD8602ARZ-REEL7 from Analog Devices is a dual-channel, precision CMOS rail-to-rail input/output operational amplifier optimized for single-supply operation from 2.7 V to 5.5 V. It delivers 8 MHz gain bandwidth, 5 V/µs slew rate, 500 µV max offset voltage, 750 µA per amplifier supply current, and operates across −40°C to +125°C - enabling high-accuracy signal conditioning in battery-powered instrumentation and sensor interfaces.
For engineers reviewing the AD8602ARZ-REEL7 datasheet, AD8602ARZ-REEL7 pinout, AD8602ARZ-REEL7 application, or AD8602ARZ-REEL7 equivalent, key selection criteria include rail-to-rail I/O swing at low supply voltage, sub-1 nA input bias current, unity-gain stability, and automotive-grade temperature qualification - all verified in the Rev. I datasheet.
Technical Context
The AD8602ARZ-REEL7 employs Analog Devices' DigiTrim® post-package trimming to achieve low offset without laser trimming, correcting mechanical stress-induced errors. Its dual-input-stage architecture - parallel NMOS and PMOS differential pairs - enables true rail-to-rail common-mode input range (0 V to VS) with seamless transition between stages.
Output stage uses complementary NMOS/PMOS common-source configuration for rail-to-rail swing; output voltage reaches within 15 mV of VS and 20 mV of GND at 1 mA load. Open-loop gain is 80 dB typical (RL = 2 kΩ), decreasing with lower load resistance - a known characteristic of rail-to-rail output topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8.4 MHz - supports stable closed-loop operation up to ~1 MHz at gain ≥10 with phase margin ≥55°. |
| Slew Rate | 6 V/µs at 5 V supply - enables clean 360 kHz full-power sine wave output with <1% distortion. |
| Input Offset Voltage | ≤500 µV max (A grade, 25°C) - ensures ≤0.5 mV error in 10× gain sensor amplification at room temperature. |
| Input Bias Current | 0.2 pA typical - allows use with >100 MΩ source impedances (e.g., photodiode, pH electrode) without significant DC error. |
| Supply Current per Amplifier | 750 µA typical at 5 V - enables dual-channel precision amplification in sub-2 mA total system budget for portable devices. |
| Rail-to-Rail Output Swing | Within 15 mV of VS and 20 mV of GND at 1 mA load - maximizes dynamic range when interfacing with 3.3 V or 5 V ADCs/DACs. |
| Operating Temperature Range | −40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-environment sensor nodes. |
Pinout & Package
AD8602ARZ-REEL7 is packaged in an 8-lead MSOP (RM suffix), measuring 3.0 mm × 3.0 mm × 0.85 mm, with exposed pad for thermal enhancement. Pin 1 is marked by dot or bevel; device is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; capable of ±50 mA drive into 2 kΩ load. |
| 2 (–IN A) | Inverting input A | High-impedance node (0.2 pA bias); connects to feedback network or signal inversion point. |
| 3 (+IN A) | Non-inverting input A | High-impedance node; accepts input common-mode voltage from 0 V to VS. |
| 4 (V–) | Negative supply / ground reference | Connects to system GND; serves as return path for both amplifiers and internal bias circuitry. |
| 5 (V+) | Positive supply | Accepts 2.7 V to 5.5 V single supply; PSRR ≥67 dB minimizes supply noise coupling. |
| 6 (+IN B) | Non-inverting input B | Independent high-Z input for second channel; identical specs to Channel A. |

Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed over full input common-mode range (0 V to VS), eliminating output latch-up during overdrive - critical for sensor fault detection circuits. |
| DigiTrim® offset calibration | Factory-trimmed offset without extra pins or external components; achieves 500 µV max without laser trimming or manual adjustment. |
| Rail-to-rail input & output | Enables direct interfacing with CMOS ASICs, 3.3 V ADCs, and DACs in single-supply systems - no level-shifting required. |
| Low 1/f noise corner | ~0.1 Hz - preserves signal integrity in DC-coupled applications like strain gauge or thermopile amplification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C drift vs. AD8602ARZ-REEL7's 2 µV/°C; higher 35 µA supply current per amp. | Better for <10 ppm/°C DC stability requirements (e.g., precision weigh scales); less suitable for low-power portable designs. | Select OPA2333AIDR only when ultra-low drift dominates over quiescent power and cost. |
| MCP6V82-E/SN | Chopper-stabilized; 3 µV max offset; 1.1 mA supply current; 2 MHz GBP - lower speed and higher power than AD8602ARZ-REEL7. | Preferred for micro-power (<1 µA) zero-drift apps with relaxed bandwidth; not viable for >100 kHz signal chains. | Choose MCP6V82-E/SN when sub-µV offset is mandatory and bandwidth ≤200 kHz suffices. |
Compared with OPA2333AIDR and MCP6V82-E/SN, AD8602ARZ-REEL7 offers optimal balance of speed (8.4 MHz), precision (500 µV offset), and ultra-low power (750 µA) - making it the preferred choice for dual-channel, battery-operated signal conditioning where 100 kHz–1 MHz bandwidth and <1 mV DC error are required.

FAQ
What is the maximum operating supply voltage for AD8602ARZ-REEL7?
The absolute maximum supply voltage for AD8602ARZ-REEL7 is 6 V, but the recommended operating range is 2.7 V to 5.5 V per the Rev. I datasheet. Operation above 5.5 V risks permanent damage, while operation below 2.7 V may degrade rail-to-rail output swing and increase input offset voltage beyond specification limits. AD8602ARZ-REEL7 is fully characterized and guaranteed across its 2.7–5.5 V range.
Does AD8602ARZ-REEL7 support rail-to-rail input with a 3.3 V supply?
Yes, AD8602ARZ-REEL7 supports true rail-to-rail input common-mode voltage from 0 V to VS, including at 3.3 V supply. Its dual-input-stage architecture (NMOS + PMOS pairs) ensures continuous operation across the full range without phase reversal or increased offset - validated in Figures 9 and 10 of the datasheet. This enables direct interfacing with 3.3 V logic and ADC references.
Is AD8602ARZ-REEL7 qualified for automotive applications?
Yes, AD8602ARZ-REEL7 is qualified for automotive applications per the datasheet's "Automotive Products" section and operates across the extended industrial temperature range of −40°C to +125°C. It meets AEC-Q100 stress test requirements for reliability and is listed in Analog Devices' automotive-grade ordering guide - making it suitable for body control modules, ADAS sensor interfaces, and infotainment system signal chains.
Can AD8602ARZ-REEL7 drive a 600 Ω audio load?
AD8602ARZ-REEL7 can drive a 600 Ω load, but with limitations: at 5 V supply and 1 kHz, THD+N is 0.001% at 1 Vpp, rising to ~0.01% at full swing (~4.9 Vpp). Output current capability is ±50 mA, sufficient for 600 Ω at ≤2.4 Vpp. For line-level audio, use 10 kΩ load per Figure 38; for 600 Ω, consider buffering or using AD8602ARZ-REEL7 in non-inverting gain-of-2 configuration to reduce output swing demand.
What is the thermal resistance (θJA) of AD8602ARZ-REEL7 in its MSOP package?
The thermal resistance θJA for AD8602ARZ-REEL7 in the 8-lead MSOP (RM) package is 142°C/W, as specified in Table 4 of the Rev. I datasheet. This value assumes standard JEDEC 4-layer board conditions. The θJC is 45°C/W, indicating efficient die-to-case conduction - critical for thermal management in sealed enclosures or high-density PCB layouts where airflow is limited.
