buffer. The device operates from supplies as low as a single ■ Industrial Temperature Range SO-8 Packages 1.2V or up to ±5V, yet it consumes only 130µA of supply ■ Rail-to-Rail Output current. ■ High Output Current: 20mA Min The input common mode range of the op amp includes ■ Output Drives 1000pF ground and incorporates phase reversal protection to pre- ■ Capable of Floating Mode Operation vent false outputs from occurring when the input is below ■ Specified for 5V and ±5V Supplies the negative supply. The rail-to-rail output stage can swing to ■ Low Reference Drift: 30ppm/°C within 15mV of each rail with no load and can swing to within ■ Industry Standard LM10 Pinout 250mV of each rail while delivering 10mA of output current. The gain bandwidth of the op amp is 175kHz and it is unity-

gain stable with up to 1000pF load capacitance.
APPLICATIO S
The 0.2V reference is referred to V – and includes a buffer ■ Battery- or Solar-Powered Systems amplifier to enhance flexibility. The reference and buffer Portable Instrumentation combine to achieve a drift of 30ppm/°C, a line regulation of Sensor Conditioning 20ppm/V and a load regulation of 150ppm/mA. ■ Precision Current Regulators ■ Precision Voltage Regulators The LT1635 is available in 8-pin PDIP and SO packages, and ■ Battery Level Indicator has the industry standard LM10 pinout. ■ Thermocouple Transmitter , LTC and LT are registered trademarks of Linear Technology Corporation.
