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.
