The AD8608ARZ-REEL7 from Analog Devices is a quad precision CMOS operational amplifier featuring rail-to-rail input and output operation. Four independent amplifiers are integrated in a single device, providing low offset, low noise and extremely low input bias current for precision sensor, filtering, photodiode and data-acquisition applications.
The AD8608 uses Analog Devices’ patented DigiTrim® trimming technology to provide excellent DC precision without conventional laser trimming. Maximum input offset voltage is only 65µV, while maximum input bias current is 1pA, making the amplifier particularly useful for high-impedance sensors and photodiode transimpedance circuits.
Dynamic performance includes a 10MHz bandwidth, approximately 5V/µs slew rate, and unity-gain stability. Voltage-noise density is typically 8nV/√Hz, providing a useful combination of precision, low noise and speed for both DC and AC signal-chain applications.
The device operates from a 2.7V to 5.5V single supply, allowing direct use in 3V, 3.3V and 5V systems. Rail-to-rail input and output operation maximizes available signal range in low-voltage designs, while typical supply current is approximately 1.15mA per amplifier under standard test conditions.
The exact AD8608ARZ-REEL7 ordering option is supplied in a 14-lead narrow SOIC (R-14) package and is specified over the extended industrial temperature range of -40°C to +125°C. ADI’s Sample & Buy page specifies Reel, 1000 pieces for the REEL7 option, and the device is currently listed as PRODUCTION.
