The RS121P/RS121BP families of products offer low voltage operation and rail-to-rail input and output, as well as excellent speed/power consumption ratio, providing an excellent bandwidth (100kHz) and slew rate of 0.04V/μs. The op-amps are unity gain stable and feature an ultra-low input bias current. The RS121P/RS121BP families of operational amplifiers are specified at the full temperature range of -40°C to 125°C under single or dual power supplies of 2.6V to 5.5V.
