Product details
Overview
AD8602DRZ-REEL7 from Analog Devices is a dual, rail-to-rail input/output precision CMOS 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-REEL7 datasheet, AD8602DRZ-REEL7 pinout, AD8602DRZ-REEL7 application, or AD8602DRZ-REEL7 equivalent, this page provides verified specifications, package mapping to 8-lead SOIC, real-world use context for current sensing and audio buffering, and validated alternative options with documented functional trade-offs.
Technical Context
The AD8602DRZ-REEL7 implements a dual-rail-to-rail input stage using parallel NMOS and PMOS differential pairs, trimmed via Analog Devices' DigiTrim® post-package process to achieve ≤500 µV offset without laser trimming. Its output stage uses complementary common-source NMOS/PMOS transistors to deliver true rail-to-rail swing - within 20 mV of V+ and 15 mV of V− at 1 mA load.
It features unity-gain stability, no phase reversal, and maintains 83 dB CMRR and 80 dB open-loop gain (RL = 2 kΩ) across its full operating temperature range. Input bias current remains ultra-low (0.2 pA typ) even at 125°C, supporting high-impedance sensor front-ends and precision shunt current monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interface with Li-ion, 3.3 V, and 5 V logic systems without level-shifting. |
| Offset Voltage (Max) | 500 µV at 25°C (A grade) - ensures ≤0.5 mV error in 1 V full-scale 12-bit ADC buffer applications. |
| Gain Bandwidth Product | 8.2 MHz - supports stable closed-loop gain ≥10 up to 800 kHz for anti-aliasing filter stages. |
| Slew Rate | 5.2 V/µs - allows clean 1 VPP output at 500 kHz without slewing distortion in audio paths. |
| Input Bias Current | 0.2 pA typical - eliminates >10 MΩ source impedance errors in photodiode or pH sensor amplifiers. |
| Output Swing | Rail-to-rail: within 20 mV of V+ and 15 mV of V− at 1 mA - maximizes dynamic range when driving SAR ADC inputs. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
AD8602DRZ-REEL7 is packaged in an 8-lead narrow SOIC (R suffix), pin-compatible with industry-standard dual op amp footprints. Thermal resistance θJA = 120°C/W on standard 4-layer PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Amplifier A output | Drives external load or next-stage input; rail-to-rail capable with <20 mV headroom at 1 mA. |
| 2 - –IN A | Inverting input A | Accepts feedback network; low input bias current preserves high-Z divider accuracy. |
| 3 - +IN A | Non-inverting input A | Connects to reference or sensor; rail-to-rail common-mode range (0 V to V+) enables single-supply biasing. |
| 4 - V– | Negative supply / ground | Reference node for dual-supply operation or system GND in single-supply configurations. |
| 5 - V+ | Positive supply | Accepts 2.7–5.5 V; PSRR of 80 dB suppresses supply noise coupling into signal path. |
| 6 - –IN B | Inverting input B | Independent channel input; identical electrical specs to Channel A for matched dual-path designs. |
| 7 - +IN B | Non-inverting input B | Enables dual-channel signal conditioning (e.g., differential sensor pair or stereo audio). |
| 8 - OUT B | Amplifier B output | Functionally identical to Pin 1; supports independent gain/feedback networks per channel. |
Key Features
| Feature | Design Value |
|---|---|
| DigiTrim® offset calibration | Post-package trimming achieves ≤500 µV max offset in SOIC without added pins or test complexity. |
| Rail-to-rail input & output | Full 0 V to V+ common-mode range and output swing preserve >99% of supply voltage as usable signal range. |
| Ultra-low input bias current | 0.2 pA typical enables accurate amplification of signals from >100 MΩ sources (e.g., piezoelectric sensors). |
| No phase reversal | Guaranteed linear behavior during input overdrive - prevents latch-up or signal inversion in protection circuits. |
| Unity-gain stable | Operates reliably with gain = 1; eliminates need for external compensation in buffer or follower configurations. |

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-REEL7's 2 µV/°C; higher 350 µA supply current. | Better for DC-coupled thermocouple amps requiring sub-µV drift; less optimal for battery-constrained audio. | Select OPA2333AIDR when long-term DC stability outweighs quiescent power; AD8602DRZ-REEL7 preferred for cost-sensitive, wide-bandwidth uses. |
| MCP6V82-E/SN | Chopper-stabilized; 15 µV max offset; 1.1 MHz GBW vs. 8.2 MHz; 125 µA supply current. | Limited bandwidth restricts use in multipole filters or fast-settling data acquisition. | Choose MCP6V82-E/SN only for ultra-low-power (<200 µA), low-frequency sensor nodes where speed is secondary. |
Compared with OPA2333AIDR and MCP6V82-E/SN, AD8602DRZ-REEL7 offers the best balance of bandwidth, precision, and supply efficiency for dual-channel signal chains operating above 100 kHz - especially where rail-to-rail I/O and 750 µA quiescent current are critical.
