Product details
Overview
AD8602DRZ-REEL from Analog Devices is a dual, 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 (A grade), 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 AD8602DRZ-REEL datasheet, AD8602DRZ-REEL pinout, AD8602DRZ-REEL application, or AD8602DRZ-REEL equivalent, key selection criteria include rail-to-rail I/O swing at low supply voltage, sub-1 nA input bias current, unity-gain stability, no phase reversal behavior, and qualification for automotive-grade temperature operation.
Technical Context
The AD8602DRZ-REEL employs Analog Devices' DigiTrim® post-package trimming to achieve low offset without laser trimming, ensuring consistent performance across 8-lead SOIC packaging. Its dual-input stage - parallel NMOS and PMOS differential pairs - enables true rail-to-rail common-mode input range (0 V to VS) and eliminates phase reversal under overdrive.
Output stage uses complementary NMOS/PMOS common-source configuration delivering rail-to-rail swing: within 20 mV of VS and 15 mV of GND at 1 mA load. Open-loop gain remains stable at ≥80 dB (RL = 2 kΩ), with 55° phase margin ensuring robust closed-loop stability in unity-gain and high-gain configurations.
Key Specifications

|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct interface with Li-ion, 3.3 V, and 5 V logic systems without level shifting. |
| Gain Bandwidth Product | 8.4 MHz - enables stable amplification of signals up to ~1 MHz in closed-loop gain ≥10 configurations. |
| Slew Rate | 6 V/µs - supports clean 1 VPP output at 1 MHz without slewing distortion in unity-gain buffer applications. |
| Input Offset Voltage (max) | 500 µV (A grade, 25°C) - ensures ≤0.5 mV error in 1 V full-scale shunt current sensing with 1 Ω sense resistor. |

| CMRR (min) | 74 dB (VCM = 0–5 V, 25°C) - rejects common-mode noise in single-supply sensor front-ends with ≥180:1 signal-to-interference ratio. |
Pinout & Package
AD8602DRZ-REEL is packaged in an 8-lead narrow SOIC (SOIC_N) with standard dual op amp pinout and surface-mount compatibility. The package meets JEDEC MS-012AC, has 1.27 mm lead pitch, and supports reflow soldering per IPC/JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output A - rail-to-rail capable, drives loads down to 2 kΩ with <30 mV drop at 1 mA sink/source. |
| 2 | −IN A | Inverting input A - high-impedance CMOS node; accepts signals from 0 V to VS without phase reversal. |
| 3 | +IN A | Non-inverting input A - matched to −IN A; enables precision differential, instrumentation, and reference buffering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C drift vs. AD8602DRZ-REEL's 2 µV/°C; higher quiescent current (17 µA vs. 750 µA). | Better for µV-level DC stability over temperature; less suitable for ultra-low-power battery operation. | Choose OPA2333AIDR when long-term DC accuracy dominates over supply current; AD8602DRZ-REEL preferred for <1 mA total system budget. |
| MCP6V82-E/SN | Auto-zeroed; 3 µV max VOS; lower bandwidth (10 MHz) but higher supply current (1.1 mA per amp). | Superior initial offset for factory-calibrated systems; higher noise (45 nV/√Hz) limits low-level AC signal fidelity. | Select MCP6V82-E/SN where sub-5 µV initial offset is mandatory and AC performance is secondary; AD8602DRZ-REEL offers better noise-bandwidth trade-off. |
Compared with OPA2333AIDR and MCP6V82-E/SN, AD8602DRZ-REEL provides optimal balance of low offset (500 µV), ultra-low bias current (0.2 pA), 8.4 MHz bandwidth, and 750 µA supply current - making it uniquely suited for dual-channel, rail-to-rail, battery-constrained precision analog signal chains.

FAQ
What is the maximum operating supply voltage for AD8602DRZ-REEL?
The absolute maximum supply voltage for AD8602DRZ-REEL is 6 V, but the recommended operating range is 2.7 V to 5.5 V per the datasheet. Operation above 5.5 V risks permanent damage; sustained use at 6 V violates the specified safe operating area and may degrade long-term reliability. Always observe the 5.5 V upper limit in production designs.
Does AD8602DRZ-REEL support rail-to-rail input with a 3.3 V supply?
Yes, AD8602DRZ-REEL supports true rail-to-rail input common-mode range from 0 V to VS, including at 3.3 V supply. Its dual NMOS/PMOS input stage ensures continuous operation across the full range without phase reversal or gain discontinuity - verified in Figures 9 and 10 of the Rev. I datasheet.
Is AD8602DRZ-REEL qualified for automotive applications?
Yes, AD8602DRZ-REEL is qualified for automotive applications per the AD8601/AD8602/AD8604 ordering guide. It is specified over −40°C to +125°C and meets AEC-Q100 stress test requirements for temperature cycling, HTOL, and ESD - confirmed in the Automotive Products section (page 22) of the Rev. I datasheet.
Can AD8602DRZ-REEL drive a 600 Ω audio load directly?
AD8602DRZ-REEL can drive 600 Ω loads with ≤0.1% THD+N at frequencies up to ~10 kHz (per Figure 38), but output swing is limited: at 5 V supply and 10 mA load, VOL = 125 mV and VOH = 4.7 V. For full 2 VPP into 600 Ω, use a dedicated audio line driver or add a discrete output stage to avoid clipping and distortion.
What is the typical input bias current of AD8602DRZ-REEL at 85°C?
The typical input bias current of AD8602DRZ-REEL is 100 pA at −40°C to +85°C (Table 1, 5 V supply), rising to 1000 pA at +125°C. This remains among the lowest in its class - critical for maintaining accuracy in high-impedance pH, ion-selective, or photodiode sensor interfaces across extended temperature ranges.
