Product details
Overview
AD8607ARZ-REEL7 from Analog Devices is a dual-channel precision micropower rail-to-rail input/output operational amplifier optimized for low-voltage, low-noise sensor signal conditioning and battery-powered instrumentation. It delivers 50 µV max offset voltage, 1 pA max input bias current, 22 nV/√Hz voltage noise density at 10 kHz, 50 µA max supply current per amplifier, and operates from 1.8 V to 5 V single supply. It is used in high-accuracy analog front-ends for medical sensors and portable gas detectors.
For engineers reviewing the AD8607ARZ-REEL7 datasheet, AD8607ARZ-REEL7 pinout, AD8607ARZ-REEL7 application, or AD8607ARZ-REEL7 equivalent, key selection criteria include micropower operation under 1.8 V, rail-to-rail I/O swing with no phase reversal, sub-50 µV offset stability over −40°C to +125°C, and SOIC-8 compatibility for legacy PCB layouts.
Technical Context
The AD8607ARZ-REEL7 implements a CMOS input stage with patented trimming for laser-free precision, enabling stable DC performance without external calibration. Its unity-gain stable architecture supports direct connection to CMOS ADCs and DACs, and its rail-to-rail input range (−0.3 V to VS + 0.3 V) and output swing (within 30 mV of rails at 1 mA) allow full utilization of low-voltage supply headroom.
It features no phase reversal up to 1 V beyond supply rails, handles capacitive loads up to 2 nF with optional snubber networks, and maintains 70° phase margin across 10 kΩ and 100 kΩ loads-enabling robust operation in multipole filters and photodiode transimpedance stages without oscillation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP2177ARZ-REEL7 | Higher precision (25 µV max offset), higher supply current (450 µA), ±15 V max supply | Better for industrial PLC analog I/O requiring <10 µV drift; not suitable for 1.8 V battery operation | Select when ultra-low drift (<0.6 µV/°C) outweighs power penalty; requires dual supply or ≥±2.5 V |

FAQ
What is the maximum supply voltage for AD8607ARZ-REEL7?
The absolute maximum supply voltage for AD8607ARZ-REEL7 is 6 V, but the recommended operating range is 1.8 V to 5.0 V single supply (or ±0.9 V to ±2.5 V dual supply). Operation above 5 V risks exceeding internal junction limits and invalidates parametric guarantees in the datasheet. The AD8607ARZ-REEL7 must be operated within this 1.8–5 V window to ensure 50 µV offset, 1 pA input bias, and rail-to-rail output swing specifications remain valid.
Does AD8607ARZ-REEL7 support rail-to-rail input at 1.8 V supply?
Yes, AD8607ARZ-REEL7 supports rail-to-rail input operation at 1.8 V supply, with input voltage range specified as −0.3 V to +1.8 V at 25°C. This allows full utilization of the supply range for sensor interfaces such as bridge amplifiers or thermistor circuits. The AD8607ARZ-REEL7 maintains no phase reversal behavior even when inputs exceed the supply by up to 1 V, enhancing robustness in low-voltage systems where transient overvoltages may occur.
Can AD8607ARZ-REEL7 drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes, AD8607ARZ-REEL7 drives a 10 kΩ load with output voltage high (VOH) ≥4.95 V and output voltage low (VOL) ≤30 mV at 5 V supply and 25°C-achieving true rail-to-rail swing. At 1.8 V supply, VOH ≥1.65 V and VOL ≤60 mV under same conditions. These values degrade predictably across temperature (e.g., VOL ≤80 mV at −40°C to +125°C), and the AD8607ARZ-REEL7 remains fully functional within these bounds for precision analog output stages.
Is AD8607ARZ-REEL7 pin-compatible with other dual op-amps in SOIC-8 packages?
No, AD8607ARZ-REEL7 is not universally pin-compatible with generic dual op-amps in SOIC-8. Its pinout follows the industry-standard dual op-amp configuration (noninverting input A, inverting input A, output A, V–, noninverting input B, inverting input B, output B, V+), matching devices like OP2177ARZ and MCP6V82-E/SN. However, electrical differences-including supply current, noise, and offset-require validation in target circuitry; direct substitution without review of biasing and stability is not recommended.
What is the thermal resistance (θJA) of AD8607ARZ-REEL7 in SOIC-8 package?
The junction-to-ambient thermal resistance (θJA) of AD8607ARZ-REEL7 in the 8-lead SOIC_N (R-8) package is 158°C/W under standard JEDEC test board conditions. This value assumes a 2-layer PCB with 1 in² copper pour per side and no internal planes. For continuous operation at maximum rated supply current (50 µA per amplifier) and ambient temperatures up to +125°C, the AD8607ARZ-REEL7 remains well within safe junction temperature limits without heatsinking or airflow.
