Preliminary
RT9134
Rail-to-Rail Quad Operational Amplifier
General Description
The RT9134 consists of low cost, high slew rates, single-
supply rail-to-rail input and output operation amplifiers.
The RT9134 contains four amplifiers in one package.
The RT9134 has high slew rates (12V/μs), 35mA
continuous output current, 120mA peak output current and
offset voltage below 10mV. The RT9134 is ideal for Thin
Film Transistor Liquid Crystal Displays (TFT-LCD).
The RT9134 is available in TSSOP-14 and VQFN-16L 4x4
package and is specified for operation over the full 40°C
to +85°C temperature range.
