LTC1150 15V Zero-Drift Operational Amplifier with Internal Capacitors FEATURES DESCRIPTIO High Voltage Operation: 16V The LTC 1150 is a high-voltage, high-performance No External Components Required zero-drift operational amplifier. The two sample-and-hold Maximum Offset Voltage: 10V capacitors usually required externally by other chopper Maximum Offset Voltage Drift: 0.05V/C amplifiers are integrated on-chip. Further, LTCs propri- Low Noise 1.8V (0.1Hz to 10Hz) etary high-voltage CMOS structures allow the LTC1150 to P-P Minimum Voltage Gain: 135dB operate at up to 32V total supply voltage. Minimum PSRR: 120dB The LTC1150 has an offset voltage of 0.5V, drift of Minimum CMRR: 110dB 0.01V/C, 0.1Hz to 10Hz input noise voltage of 1.8V P-P Low Supply Current: 0.8mA and a typical voltage gain of 180dB. The slew rate of 3V/s Single Supply Operation: 4.75V to 32V and a gain bandwidth product of 2.5MHz are achieved with Input Common Mode Range Includes Ground 0.8mA of supply current. Overload recovery times from 200A Supply Current with Pin 1 Grounded positive and negative saturation conditions are 3ms and Typical Overload Recovery Time 20ms 20ms, respectively. U For applications demanding low power consumption, APPLICATIO S Pin 1 can be used to program the supply current. Pin 5 is an optional AC-coupled clock input, useful for Strain Gauge Amplifiers synchronization. Electronic Scales Medical Instrumentation The LTC1150 is available in standard 8-lead, plastic dual- Thermocouple Amplifiers in-line package, as well as an 8-lead SO package. The High Resolution Data Acquisition LTC1150 can be a plug-in replacement for most standard bipolar op amps with significant improvement in DC performance. , LTC and LT are registered trademarks of Linear Technology Corporation.
