Single-supply op-amp for signal conditioning chains
The Analog Devices AD8614ARTZ-REEL7 is a single-channel, general-purpose operational amplifier with a gain-bandwidth product of 5.5 MHz and a rail-to-rail output stage. It operates from a single supply between 5 V and 18 V, or from split supplies up to ±9 V, drawing 800 µA quiescent current. The 7.5 V/µs slew rate supports moderate-speed signal paths — think sensor buffers, ADC drivers, or active filters in the audio to low-MHz range. The SOT-23-5 footprint (SC-74A / SOT-753) is a common layout for compact single-channel designs.
Supply range and output swing — what they mean for the rail budget
The 5 V minimum supply lets this part run from a standard 5 V logic rail, while the 18 V maximum allows use in ±9 V split-supply systems or unregulated 12 V industrial buses. The rail-to-rail output swings within millivolts of each rail, preserving dynamic range in low-voltage single-supply chains — useful when the ADC reference is the supply itself. The 70 mA output current per channel is enough to drive moderate loads like a 100 Ω line or a small relay directly.
Temperature grade and environment
Rated for -20°C to 85°C operating temperature, this part fits commercial and light industrial environments — office equipment, test instrumentation, indoor control panels. It is not specified for automotive under-hood or extended outdoor enclosures where -40°C to 125°C range is typical. The input offset voltage is 1 mV maximum, and input bias current is 80 nA, both adequate for general-purpose signal conditioning but not precision instrumentation.
Lifecycle and compliance
It is RoHS3 compliant, which simplifies compliance for EU-market products.
