ADI features their AD8605 (single), AD8606 (dual), and AD8608 (quad) rail-to-rail input and output (RRIO) operational amplifiers. These op amps use DigiTrim® technology for precision trimming. The AD8605, AD8606, and AD8608 have low offset voltage (80 mA), low input voltage (2.7 V to 5.5 V), current noise (8 nV/√Hz), and wide bandwidth 10 MHz. They come in a variety of packages including SOT-23, WLCSP, TSSOP, and MSOP, and they have a wide operational temperature range from -40°C to +125°C. The AD8605, AD8606, and AD8608 are perfect for handheld, battery, and audio applications.
