Product details
Overview
AD8601WDRTZ-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 sensor interfaces.
For engineers reviewing the AD8601WDRTZ-REEL datasheet, AD8601WDRTZ-REEL pinout, AD8601WDRTZ-REEL application, or AD8601WDRTZ-REEL equivalent, key selection criteria include rail-to-rail I/O capability at low supply voltage, sub-1 mV offset stability over temperature, ultra-low input bias current (0.2 pA typ), and automotive-grade qualification (−40°C to +125°C).
Technical Context
The AD8601WDRTZ-REEL employs Analog Devices' DigiTrim® post-package trimming to achieve precise offset voltage without laser trimming, ensuring stability across mechanical stress and temperature. Its dual-input-stage architecture - parallel NMOS and PMOS differential pairs - enables true rail-to-rail common-mode input range (0 V to VS) and seamless transition between input stages.
Output stage uses 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 (typ) into 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 - ensures ≤0.01% gain error in 10 V full-scale precision current sensing. |
| Gain Bandwidth Product | 8.2 MHz - enables stable closed-loop operation up to 100 kHz with G = 100, suitable for multipole active filters. |
| Slew Rate | 5.2 V/µs - supports clean 1 VPP signals up to ~800 kHz without slewing distortion. |
| Input Bias Current | 0.2 pA typical - eliminates significant voltage drop across >100 MΩ source impedances (e.g., photodiode, pH electrode). |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive sensors and industrial motor control feedback paths. |
| Output Drive | ±30 mA - drives 2 kΩ loads to rail while maintaining linearity; sufficient for driving ADC reference buffers or DAC outputs. |
Pinout & Package
AD8601WDRTZ-REEL is housed in a 5-lead SOT-23 (RJ suffix) package with exposed pad for thermal enhancement. Pin 1 is OUT, Pin 2 is V–, Pin 3 is +IN, Pin 4 is –IN, Pin 5 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Rail-to-rail capable; sinks/sources ±30 mA; settles to 0.01% in <0.5 µs with 2 kΩ load. |
| 2 (V–) | Negative supply / ground reference | Connect directly to system ground; supports single-supply operation with no negative rail required. |
| 3 (+IN) | Non-inverting input | CMOS input with 0.2 pA bias current; accepts common-mode voltages from 0 V to VS. |
| 4 (–IN) | Inverting input | Matches +IN in offset, bias, and CMRR; enables precision difference amplification with matched external resistors. |
| 5 (V+) | Positive supply | Accepts 2.7 V–5.5 V; PSRR of 67–80 dB minimizes supply noise coupling into signal path. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed under all input overdrive conditions - prevents latch-up or signal inversion in sensor front-ends during transient excursions. |
| Rail-to-rail input & output | Enables full utilization of 3 V or 5 V ADC/DAC dynamic range without external level-shifting circuitry. |
| DigiTrim® trimming | Post-package offset calibration eliminates assembly-induced stress errors - critical for consistent performance in miniaturized SOT-23 layout. |

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 | Zero-drift architecture; 10 µV max offset; 350 kHz GBW; 17 µA supply current | Better dc precision but lower speed - suited for weigh scales, thermocouple amps, not audio or fast filters | Select when ultra-low drift (<0.1 µV/°C) outweighs bandwidth needs; avoid if >500 kHz signal content exists. |
| MCP6V81T-E/OT | Zero-drift; 25 µV max offset; 10 MHz GBW; 1.6 mA supply current; SC-70-5 package | Higher speed and precision, but 2× supply current - requires careful thermal management in dense layouts | Choose for higher-accuracy, higher-bandwidth trade-off where power budget allows; verify thermal derating in SOT-23 footprint. |
Compared with OPA333AIDBVR and MCP6V81T-E/OT, AD8601WDRTZ-REEL offers optimal balance of 8 MHz bandwidth, 500 µV offset, and 750 µA quiescent current in the industry-standard 5-lead SOT-23 - making it preferred for cost-sensitive, battery-operated systems requiring both speed and precision without zero-drift complexity.

FAQ
What is the maximum operating temperature range for AD8601WDRTZ-REEL?
The AD8601WDRTZ-REEL is specified for operation from −40°C to +125°C and qualified per AEC-Q100 Grade 1. This extended industrial temperature range ensures reliable performance in under-hood automotive environments, industrial motor drives, and outdoor instrumentation where ambient temperatures exceed standard commercial limits. The device maintains its 500 µV max offset and 8 MHz bandwidth across this full range.
Does AD8601WDRTZ-REEL require external compensation for unity-gain stability?
No, AD8601WDRTZ-REEL is internally compensated and unity-gain stable. The datasheet explicitly confirms stability with closed-loop gains ≥1, including voltage follower (G = 1) configurations. No external capacitors or resistors are needed for stability - simplifying PCB layout and reducing BOM count in precision buffer and gain-stage designs.
Can AD8601WDRTZ-REEL drive capacitive loads directly?
AD8601WDRTZ-REEL can drive moderate capacitive loads (≤100 pF) without instability, but larger loads require isolation. Figure 33 and Figure 34 show overshoot increases above 100 pF; for >200 pF (e.g., long traces or ADC input caps), a series resistor (10–100 Ω) between AD8601WDRTZ-REEL output and the load restores phase margin and settling behavior.
Is AD8601WDRTZ-REEL pin-compatible with other SOT-23 op amps?
Yes, AD8601WDRTZ-REEL uses the industry-standard 5-lead SOT-23 pinout (OUT, V–, +IN, –IN, V+), matching common single-op-amp footprints like TLV2461, MCP6001, and OPA340. This allows drop-in replacement in existing layouts - provided supply voltage (2.7–5.5 V), offset, and bandwidth requirements align with the design intent.
What is the typical input bias current of AD8601WDRTZ-REEL at 85°C?
At 85°C, the typical input bias current of AD8601WDRTZ-REEL remains ≤25 pA (per Table 1), with a maximum of 100 pA. This ultra-low, temperature-stable bias current enables accurate amplification of high-impedance sources - such as piezoelectric sensors or electrochemical cells - without introducing measurable error across the extended industrial temperature range.
