RT9146/7
20V, 1A, Rail-to-Rail Operational Amplifier
General Description
Features
The RT9146/7 consists of a low power, high slew rate,
single supply rail-to-rail input and output operational
amplifier.
The RT9146 contains a single amplifier and the RT9147
contains two amplifiers in one package.
The RT9146/7 has a high slew rate (35V/μs), 1A peak
output current and offset voltage below 15mV. The RT9146/
7 is ideal for Thin Film Transistor Liquid Crystal Displays
(TFT-LCD) .
The RT9146 is available in the WDFN-8L 3x3 package,
and the RT9147 is available in the WQFN-16L 4x4
package. The RT9146/7 are specified for operation over
the full −40°C to 85°C temperature range.

Note 1. Stresses beyond those listed “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in
the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may
affect device reliability.
Note 2. θJA is measured at TA = 25°C on a high effective thermal conductivity four-layer test board per JEDEC 51-7. θJC is
measured at the exposed pad of the package.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
