350 DATASHEET 5V Ultra Low Noise, Zero Drift Rail-to-Rail Precision Op Amp ISL28134 Features The ISL28134 is a single, chopper-stabilized zero drift Rail-to-rail inputs and outputs operational amplifier optimized for single and dual supply - CMRR at V = 0.1V beyond V . 135dB, typ CM S operation from 2.25V to 6.0V and 1.125V and 3.0V. The -V and V .10mV from V , typ OH OL S ISL28134 uses auto-correction circuitry to provide very low input No 1/f noise corner down to 0.1Hz offset voltage, drift and a reduction of the 1/f noise corner below 0.1Hz. The ISL28134 achieves ultra low offset voltage, offset - Input noise voltage .10nV/Hz at 1kHz temperature drift, wide gain bandwidth and rail-to-rail - 0.1Hz to 10Hz noise voltage . 250nV P-P input/output swing while minimizing power consumption. Low offset voltage 2.5V, Max The ISL28134 is ideal for amplifying the sensor signals of analog Superb offset drift . 15nV/C, Max front-ends that include pressure, temperature, medical, strain gauge and inertial sensors down to the V levels. Single supply 2.25V to 6.0V The ISL28134 can be used over standard amplifiers with high Dual supply . 1.125V to 3.0V stability across the industrial temperature range of -40C to Low I . 675A, typ CC +85C and the full industrial temperature range of -40C to Wide bandwidth . 3.5MHz +125C. The ISL28134 is available in an industry standard pinout SOIC and SOT-23 packages. Operating temperature range - Industrial -40C to +85C Applications - Full industrial .-40C to +125C Medical instrumentation Packaging Sensor gain amps - Single: SOIC, SOT-23 Precision low drift, low frequency ADC drivers Precision voltage reference buffers Related Literature AN1641, ISL28134SOICEVAL1Z Evaluation Board Users Thermopile, thermocouple, and other temperature sensors Guide front-end amplifiers AN1560, Making Accurate Voltage Noise and Current Noise Inertial sensors Measurements on Operational Amplifiers Down to 0.1Hz Process control systems Weight scales and strain gauge sensors 1600 V = 2.5V 1400 s V = 0V +5 CM T = -40C to +125C 1200 ISL28134 ISL26102 N = 2796 + 1000 50 ISL22316 24-BIT ADC - 800 50k ISL21010 600 50k - 50 5V VREF 400 DCP + 200 ISL28134 0 -2.5 -2.0 -1.5 -1.0 -0.5 0 0.5 1.0 1.5 2.0 2.5 FIGURE 1.
