Description

The LT6656 is a tiny precision voltage reference that draws less than 1μA of supply current and can operate with a supply voltage within 10mV of the output voltage. The LT6656 offers an initial accuracy of 0.05% and temperature drift of 10ppm/°C. The combined low power and precision characteristics are ideal for portable and battery powered instrumentation.The LT6656 can supply up to 5mA of output drive with 65ppm/mA of load regulation, allowing it to be used as the supply voltage and the reference input to a low power ADC. The LT6656 can accept a supply voltage up to 18V and withstand the reversal of the input connections.The LT6656 output is stable with 1μF or larger output capacitance and operates with a wide range of output capacitor ESR.This reference is fully specified for operation from –40°C to 85°C, and is functional over the extreme temperature range of –55°C to 125°C. Low hysteresis and a consistent temperature drift are obtained through advanced design, processing and packaging techniques.The LT6656 is offered in the 6-lead SOT-23, (2mm × 2mm) DFN, and 8-lead LS8 Packages. The LS8 is a 5mm × 5mm surface mount hermetic package that provides outstanding stability.APPLICATIONSPrecision A/D and D/A ConvertersPortable Gas MonitorsBattery- or Solar-Powered SystemsPrecision RegulatorsLow Voltage Signal ProcessingMicropower Remote Sensing
