OPAx196 36-V, Low-Power, Low Offset Voltage, Rail-to-Rail Operational Amplifier
1 Features 3 Description
• LowOffsetVoltage: ±100µV(maximum) The OPAx196 family (OPA196, OPA2196, and
1 OPA4196) is a new generation of 36-V, rail-to-rail e-
• LowOffsetVoltageDrift: ±0.5 µV/°C(typical)
trim™operationalamplifiers(opamps).
• LowBiasCurrent: ±5pA(typical)
These devices offer very low offset voltage (±25 μV,
• HighCommon-ModeRejection:140dB
typical), drift (±0.5 μV/°C, typical), and low bias
• LowNoise:15nV/√Hzat1kHz current (±5 pA, typical) combined with very low
• Rail-to-RailInputandOutput quiescent current (140μA/channel, typical)acrossthe
entireoutputrange.
• DifferentialInputVoltageRangetoSupplyRail
• WideBandwidth:2.5-MHzGBW Unique features, such as differential input-voltage
range to the supply rail, high output current (±65 mA),
• LowQuiescentCurrent:140µAperAmplifier
and high capacitive load drive of up to 1 nF make the
(typical)
OPAx196 a robust, high-performance operational
• WideSupply:±2.25Vto±18V,4.5Vto36V amplifierfor high-voltageindustrialapplications.
• EMI/RFI FilteredInputs
The OPAx196 family of op amps is available in
• HighCapacitiveLoadDriveCapability:1nF standard packages and is specified from –40°C to
• IndustryStandardPackages: +125°C.
