Preliminary
RT9133A/B
Rail-to-Rail Operational Amplifier
General Description
Features
z Rail-to-Rail Output Swing
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/us), 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).
z Supply Voltage : 4.5V to 15V
z Continuous Output Current : 35mA
z Peak Output Current : 120mA
z High Slew Rate : 12V/μs
z Offset Voltage : 10mV
z RoHS Compliant and 100% Lead (Pb)-Free
Applications
The RT9133Ais 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.
