LTC1151 Dual 15V Zero-Drift Operational Amplifier FEATURES DESCRIPTIO Maximum Offset Voltage Drift: 0.05V/C The LTC 1151 is a high voltage, high performance dual High Voltage Operation: 18V zero-drift operational amplifier. The two sample-and-hold No External Components Required capacitors per amplifier required externally by other chop- Maximum Offset Voltage: 5V per amplifiers are integrated on-chip. The LTC1151 also Low Noise: 1.5V (0.1Hz to 10Hz) incorporates proprietary high voltage CMOS structures P-P Minimum Voltage Gain: 125dB which allow operation at up to 36V total supply voltage. Minimum CMRR: 106dB The LTC1151 has a typical offset voltage of 0.5V, Minimum PSRR: 110dB drift of 0.01V/C, 0.1Hz to 10Hz input noise voltage of Low Supply Current: 0.9mA/Amplifier 1.5V , and a typical voltage gain of 140dB. It has a slew P-P Single Supply Operation: 4.75V to 36V rate of 3V/s and a gain-bandwidth product of 2.5MHz Input Common Mode Range Includes Ground with a supply current of 0.9mA per amplifier. Overload Typical Overload Recovery Time: 20ms recovery times from positive and negative saturation are Available in 8-Lead N8 and 16-Lead SW Packages 3ms and 20ms, respectively. U The LTC1151 is available in a standard 8-lead plastic DIP APPLICATIO S package as well as a 16-lead wide body SO. The LTC1151 Strain Gauge Amplifiers is pin compatible with industry-standard dual op amps Instrumentation Amplifiers and runs from standard 15V supplies, allowing it to plug Electronic Scales in to most standard bipolar op amp sockets while offering Medical Instrumentation significant improvement in DC performance.
