RS124XP

RS121S, RS122S RS121, RS122, RS124 150kHz, Rail-to-Rail I/O CMOS Operational Amplifier FEATURES DESCRIPTION • GAIN BANDWIDTH:150kHz • RAIL-TO-RAIL INPUT AND OUTPUT 0.8mV Typical Vos • • INPUT VOLTAGE RANGE: -0.1V to +5.6V with Vs = 5.5V SUPPLY RANGE: +2.5V to +5.5V • SHUTDOWN: RS121S/RS122S • SPECIFIED UP TO +125°C • MicroSIZE The RS121, RS122, RS124, RS121S, RS122S 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 (150kHz) and slew rate of 0.05V/us. The op-amps are unity gain stable and feature an ultra-low input bias current. The devices are ideal for sensor interfaces, active filters and portable applications. The RS121S, RS122S include a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is less than 1uA.The RS121, RS122, RS124, RS121S, RS122S 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.

Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less.
