LT6656ACS6-4.096#TRPBF

Voltage Reference Overview

The LT6656ACS6-4.096#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 4.096V with an initial accuracy of ±0.05% and a temperature coefficient of 10ppm/°C. It operates within a supply range of 2.51V to 18V, drawing a typical supply current of 1µA (max 1.5µA). The device provides up to 5mA of output drive current and includes reverse input/output protection. It is housed in a 6-lead TSOT-23 package and specified for operation from 0°C to 70°C.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications
• High precision with low temperature drift and tight initial accuracy
• Capable of sourcing up to 5mA output drive current
• Includes reverse input and output protection

Voltage Reference Applications

• Precision A/D and D/A converters
• Portable gas monitors
• Battery- or solar-powered systems
• Micropower remote sensing

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the 'C' grade designation aligns with the required commercial temperature range of 0°C to 70°C. Ensure the 4.096V output option matches the system requirements. Check for lead-free finish compliance if necessary.

Voltage Reference Selection Notes

Select this component for designs requiring high precision in a compact surface-mount package. The TSOT-23 form factor is ideal for space-constrained portable electronics. Consider the 0°C to 70°C operating range; for wider industrial temperatures, the 'I' grade variant is available. The low dropout characteristic allows operation close to the output voltage.

Voltage Reference Part Context

This part belongs to the LT6656 family of 1µA precision series voltage references. It shares core architectural features with other grades like the AIS6 and BCS6 variants but differs in temperature specification and accuracy class. The LS8 and DC packages offer alternative form factors for different thermal or stability needs.

Voltage Reference Replacement Considerations

LT6656AIS6-4.096#TRPBF offers identical electrical performance but is rated for the –40°C to 85°C industrial temperature range instead of the commercial 0°C to 70°C range.
