The RS321BK products offer low voltage operation and rail-to-rail input and output, as well as excellent speed/power consumption ratio, providing an excellent bandwidth (1MHz) and slew rate of 0.45V/μs. The op-amps are unity gain stable and feature an ultra-low input bias current. The RS321BK has lower offset, which is guaranteed not upper than ±4.5mV at 25°C with Vs = 5V, VCM = Vs/2. The devices are ideal for sensor interfaces, active filters and portable applications. The RS321BK families of operational amplifiers are specified at the full temperature range of −40°C to +125°C under single or dual power supplies of 2.5V to 5.5V.
