RT9146/7
20V, 1A, Rail-to-Rail Operational Amplifier
General Description
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 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 a WDFN-8L 3x3 package. The
RT9147 is available in a WQFN-16L 4x4 package. The
RT9146/7 are specified for operation over the full −40°C to
85°C temperature range.
