Ultralow Supply Current: 850nA
The LT®6656 is a tiny precision voltage reference that n
Low Drift
draws less than 1µA of supply current and can operate
A Grade: 10 ppm/°C Max
with a supply voltage within 10mV of the output voltage.
B Grade: 20 ppm/°C Max
The LT6656 offers an initial accuracy of 0.05% and tem- n
High Accuracy
perature drift of 10ppm/°C. The combined low power and
A Grade: 0.05% Max

Long-Term Drift: 15ppm/√kHr (LS8 Package)
The LT6656 can supply up to 5mA of output drive with n
No Humidity Sensitivity (LS8 Package)
65ppm/mA of load regulation, allowing it to be used as n High Output Drive Current: 5mA Min the supply voltage and the reference input to a low power n Low Dropout Voltage: 10mV Max ADC. The LT6656 can accept a supply voltage up to 18V n Fully Specified from –40°C to 85°C and withstand the reversal of the input connections. n Operational from –55°C to 125°C n Wide Supply Range to 18V The LT6656 output is stable with 1µF or larger output n Reverse Input/Output Protection capacitance and operates with a wide range of output n Available Output Voltage Options: capacitor ESR. 1.25V, 2.048V, 2.5V, 3V, 3.3V, 4.096V and 5V This reference is fully specified for operation from –40°C n Available in Low Profile (1mm) ThinSOT™, to 85°C, and is functional over the extreme temperature (2mm × 2mm) DFN and High Stability Hermetic range of –55°C to 125°C. Low hysteresis and a consistent (5mm × 5mm) LS8 Packages temperature drift are obtained through advanced design, processing and packaging techniques.
APPLICATIONS
The LT6656 is offered in the 6-lead SOT-23, (2mm × n Precision A/D and D/A Converters 2mm) DFN, and 8-lead LS8 Packages. The LS8 is a 5mm n Portable Gas Monitors × 5mm surface mount hermetic package that provides n Battery- or Solar-Powered Systems outstanding stability. n Precision Regulators L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and n Low Voltage Signal Processing ThinSOT is a trademark of Linear Technology Corporation.
