The two sample-and-hold capacitors per amplifier required externally by other chop- per 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 0.5 µV, drift of 0.01 µV/°C, 0.1Hz to 10Hz input noise voltage of 1.5 µVP-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 3ms and 20ms, respectively. The LTC1151 is available in a standard 8-lead plastic DIP package as well as a 16-lead wide body SO. The LTC1151 is pin compatible with industry-standard dual op amps and runs from standard ±15V supplies, allowing it to plug in to most standard bipolar op amp sockets while offering significant improvement in DC performance. ■ Strain Gauge Amplifiers ■ Instrumentation Amplifiers ■ Electronic Scales ■ Medical Instrumentation ■ Thermocouple Amplifiers ■ High Resolution Data Acquisition ■ Maximum Offset Voltage Drift: 0.05 µV/°C ■ High Voltage Operation: ±18V ■ No External Components Required ■ Maximum Offset Voltage: 5 µV ■ Low Noise: 1.5 µVP-P (0.1Hz to 10Hz) ■ Minimum Voltage Gain: 125dB ■ Minimum CMRR: 106dB ■ Minimum PSRR: 110dB ■ Low Supply Current: 0.9mA/Amplifier ■ Single Supply Operation: 4.75V to 36V ■ Input Common Mode Range Includes Ground ■ Typical Overload Recovery Time: 20ms ■ Available in 8-Lead N8 and 16-Lead SW Packages Noise Spectrum ±15V Dual Thermocouple Amplifier FREQUENCY (Hz) 10 20 30 40 60 1 100 1k 10k 1151 TA02 0 10 50 , LTC and LT are registered trademarks of Linear Technology Corporation.
