Product details
Overview
AD8601ARTZ-REEL from Analog Devices is a precision CMOS single-supply rail-to-rail input/output operational amplifier in a 5-lead SOT-23 package. It delivers 500 µV max offset voltage, 8 MHz gain bandwidth, 5 V/µs slew rate, 750 µA supply current, and operates from 2.7 V to 5.5 V - enabling high-accuracy signal conditioning in battery-powered instrumentation and shunt-based current sensing.
For engineers reviewing the AD8601ARTZ-REEL datasheet, AD8601ARTZ-REEL pinout, AD8601ARTZ-REEL application, or AD8601ARTZ-REEL equivalent, key selection criteria include rail-to-rail I/O swing at low supply voltage, sub-1 nA input bias current over temperature, guaranteed −40°C to +125°C operation, and DigiTrim®-enabled offset stability without laser trimming.
Technical Context
The AD8601ARTZ-REEL uses a dual-input-stage architecture (parallel NMOS and PMOS differential pairs) to achieve true rail-to-rail common-mode input range (0 V to VS). Its patented DigiTrim® post-package trimming corrects assembly-induced mechanical stress offsets, delivering 500 µV max VOS across temperature without added pins or layout complexity.
Output stage employs complementary NMOS/PMOS common-source configuration for rail-to-rail swing: at 1 mA load, output reaches within 20 mV of VS and 15 mV of ground. Open-loop gain is 80 dB typical (RL = 2 kΩ), with phase margin of 50°–55° and unity-gain stability confirmed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| 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. |
| Offset Voltage (Max) | 500 µV at 25°C - enables <1 LSB error in 12-bit ADC front-ends with ±2.5 V full-scale input. |
| Gain Bandwidth Product | 8.4 MHz - supports stable closed-loop gain ≥10 up to ~800 kHz with adequate phase margin. |
| Slew Rate | 6 V/µs at 5 V supply - ensures <100 ns settling for 2 V step with <0.1% error in portable audio and sensor interfaces. |
| Input Bias Current | 0.2 pA typical - permits use with >100 MΩ source impedances (e.g., photodiode, pH electrode) without significant DC error. |
| Operating Temperature | −40°C to +125°C - qualified for automotive engine control, industrial motor drives, and under-hood sensor signal conditioning. |
| Output Drive | ±50 mA - sustains 2 kΩ load at rail-to-rail swing while maintaining linearity for active filter and driver stages. |
Pinout & Package
AD8601ARTZ-REEL is housed in a 5-lead SOT-23 (RJ suffix) package with 1.6 mm × 2.8 mm footprint and 0.95 mm height, optimized for space-constrained portable and automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±50 mA into resistive loads. |
| 2 - V− | Negative supply / ground reference | Connects to system ground or negative rail; serves as return path for input bias and output current. |
| 3 - +IN | Non-inverting input | High-impedance node (0.2 pA bias); accepts common-mode voltages from 0 V to VS. |
| 4 - −IN | Inverting input | Matches +IN in bias, offset, and CMRR; used for feedback network connection in standard configurations. |
| 5 - V+ | Positive supply | Accepts 2.7 V–5.5 V; PSRR of 80 dB minimizes supply noise coupling into output signal. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Lower offset (10 µV typ), but 350 kHz GBP and 160 µA supply current - trades speed for ultra-low offset and zero-drift stability. | Better for dc-critical sensor bridges; unsuitable for >100 kHz active filters or audio paths requiring 8 MHz bandwidth. | Select OPA333AIDBVR when long-term dc stability outweighs bandwidth needs; AD8601ARTZ-REEL preferred for wideband signal chains. |
| MCP6001T-E/OT | Higher offset (1.5 mV max), 1 MHz GBP, 100 µA supply current - cost-optimized general-purpose rail-to-rail op amp. | Acceptable for non-precision battery monitors or LED drivers; lacks DigiTrim® and automotive qualification. | Choose MCP6001T-E/OT for cost-sensitive consumer devices where 500 µV offset and AEC-Q100 are not required. |
Compared with OPA333AIDBVR and MCP6001T-E/OT, AD8601ARTZ-REEL uniquely balances 8 MHz bandwidth, 500 µV offset, and −40°C to +125°C operation in a 5-lead SOT-23 - making it optimal for automotive current sensing and portable test equipment demanding both speed and precision.

FAQ
What is the maximum operating temperature range for AD8601ARTZ-REEL?
AD8601ARTZ-REEL is specified for operation from −40°C to +125°C and qualified per AEC-Q100 Grade 1 standards. This extended industrial temperature range enables reliable deployment in under-hood automotive electronics, industrial motor controllers, and outdoor instrumentation where ambient temperatures exceed 85°C.
Does AD8601ARTZ-REEL require external compensation for unity-gain stability?
No, AD8601ARTZ-REEL is internally compensated and unity-gain stable across its full operating range. The datasheet confirms stable operation with closed-loop gains ≥1, including voltage follower configurations, without added external components - simplifying design for sensor buffers and reference followers.
Can AD8601ARTZ-REEL drive capacitive loads without oscillation?
AD8601ARTZ-REEL exhibits controlled overshoot up to 1000 pF (Figure 33–34), but for loads >100 pF, a small series resistor (10–50 Ω) at the output is recommended to maintain phase margin. Its robust transient response (Figures 45–48) supports stable operation into typical PCB trace and ADC input capacitance without external isolation.
How does DigiTrim® technology improve AD8601ARTZ-REEL performance versus conventional CMOS op amps?
DigiTrim® performs post-package offset trimming to correct mechanical stress-induced mismatches - achieving 500 µV max VOS in the 5-lead SOT-23 package, which is unattainable with laser trimming alone. This enables high precision in miniature packages without sacrificing yield or adding pins, directly benefiting space-constrained portable designs using AD8601ARTZ-REEL.
Is AD8601ARTZ-REEL pin-compatible with other members of the AD860x family?
No - AD8601ARTZ-REEL is a single-amplifier variant in 5-lead SOT-23. AD8602 (dual) uses 8-lead MSOP/SOIC, and AD8604 (quad) uses 14- or 16-lead packages. Pinouts differ entirely; only functional equivalence exists within the family. System-level replacement requires PCB redesign when migrating between AD8601ARTZ-REEL and AD8602/AD8604 variants.
