Rail-to-Rail Operational Amplifier

RT9133A/RT9133B

Update Alert Share

The RT9133A/B consist low cost, high slew rates, single-supply rail-to-rail input and output operation amplifiers. The RT9133A contains a single amplifier and RT9133B contains two amplifiers. The RT9133A/B have high slew rates (12V/μs), 35mA continuous output current, 120mA peak output current and offset voltage below 10mV. The RT9133A/B are ideal for Thin Film Transistor Liquid Crystal Displays (TFT-LCD).
The RT9133A is available in SOT-23-5 and WDFN-6L 2x2 packages. The RT9133B is available in MSOP-8 package. The RT9133A/B are specified for operation over the full   -40°C to +85°C temperature range.
