LTC1151CN8#PBF Datasheet PDF - Linear Technology

●The LTC1151CN8#PBF is a high voltage/performance dual zero-drift Operational Amplifier for use with electronic scales. The two sample-and-hold capacitors per amplifier required externally by other chopper amplifiers are integrated on-chip. The LTC1151 also incorporates proprietary high voltage CMOS structures which allow operation at up to 36V total supply voltage. The LTC1151 has a typical offset voltage of 0.5µV, drift of 0.01µV/°C, 0.1 to 10Hz input noise voltage of 1.5µVP-P and a typical voltage gain of 140dB. It has a slew rate of 3V/µs and a gain-bandwidth product of 2.5MHz with a supply current of 0.9mA per amplifier. Overload recovery times from positive and negative saturation are 3 and 20ms, respectively.
