RS621S, RS622S RS621, RS622, RS624 7MHz, Rail-to-Rail I/O CMOS Operational Amplifier FEATURES DESCRIPTION HIGH GAIN BANDWIDTH:7MHz RAIL-TO-RAIL INPUT AND OUTPUT 0.7mV Typical Vos INPUT VOLTAGE RANGE: -0.1V to +5.6V with Vs = 5.5V SUPPLY RANGE: +2.5V to +5.5V SHUTDOWN: RS621S/RS622S SPECIFIED UP TO +125°C MicroSIZE The RS62X 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 (7MHz) and slew rate of 3.7V/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 RS621S, RS622S 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 RS62X 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.

Supply voltages higher than 7V (absolute maximum) can permanently damage the amplifier. +Vs 10uF 0.1uF Vin Rail-to-rail input and output swing significantly increases dynamic range, especially in low-supply applications. Vip Vout RS62X 10uF 0.1uF Good layout practice mandates use of a 0.1uF capacitor place closely across the supply pins. -Vs RS621S/RS622S ENABLE FUNCTION Figure1. Amplifier with Bypass Capacitors The RS621S/RS622S includes a shutdown mode. Under logic control, the amplifiers can be switched from normal mode to a standby current of 1uA. When the Enable pin is connected to high, the amplifier is active. Connecting Enable low disables the amplifier, and places the amplifier, and place the output in a high-impedance state. INSTRUMENTATION AMPLIFIER In the three-op amp, instrumentation amplifier configuration shown in Figure2, V1 LAYOUT GUIDELINS RS62X Attention to good layout practices is always recommended. Keep traces short. When possible, use a PCB ground plane with surface-mount components placed as close to the device pins as possible. Place a 0.1uF capacitor closely across the supply pins. These guidelines should be applied throughout the analog circuit to improve performance and provide benefits such as reducing the EMI susceptibility. RS62X VOUT RS62X V2 Figure2.
