RT9137/8/9
Rail-to-Rail Operational Amplifier
General Description
The RT9137/RT9138/RT9139 consist low power, high slew rates, rail-to-rail input and output operation amplifiers.
The RT9137 contains a single amplifier, RT9138 contains two amplifiers and RT9139 contains four amplifiers in one package.
The RT9137/RT9138/RT9139 have high slew rates (120V/μs), 35mA continuous output current, 300mA peak output current and offset voltage below 16.5mV.
The RT9137 is available in TSOT-23-5 and WDFN-6L 2x2 packages. The RT9138 is available in MSOP-8 and WDFN-6L 2x2 packages. The RT9139 is available in WQFN-16L 4x4, TSSOP-14, TSSOP-14 (Exposed Pad), MSOP-10 and WDFN-10L 3x3 package.
The RT9137/RT9138/RT9139 are specified for operation over the full −40°C to 85°C temperature range.
