LT6656ACDC-2.048#TRMPBF

Voltage Reference Overview

The LT6656ACDC-2.048#TRMPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring an output voltage of 2.048V and housed in a 6-lead (2mm × 2mm) plastic DFN package. It delivers an initial accuracy of 0.1% with a maximum temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 2.058V to 18V, drawing a typical supply current of 1µA. It provides a minimum output drive current of 5mA and requires a minimum output capacitance of 1µF for stable operation.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications
• Low dropout voltage allowing operation with minimal headroom
• Reverse input and output protection capabilities
• Stable operation with a wide range of output capacitor ESR values

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 #TRMPBF indicates tape and reel packaging when sourcing. Confirm the AC grade designation corresponds to the required 0.1% initial accuracy and 10ppm/°C drift specifications. Ensure the DC package type matches the PCB footprint requirements. Check that the commercial temperature range meets the operational environment needs.

Voltage Reference Selection Notes

Select this component for designs requiring low power consumption alongside moderate precision. The 2.048V output is ideal for driving ADCs directly. Consider the DFN package for space-constrained layouts. Verify that the load regulation and noise performance meet the system requirements compared to higher-grade options.

Voltage Reference Part Context

This part belongs to the LT6656 family of 1µA precision series voltage references. It shares core architectural features with other variants but differs in output voltage, accuracy grade, and package style. The ACDC variant specifically combines the C grade accuracy with the compact DFN form factor.

Voltage Reference Replacement Considerations

LT6656BCDC-2.048#TRMPBF offers 0.2% accuracy. LT6656AIDC-2.048#TRMPBF provides industrial temperature range. LT6656AIS6-2.048#TRMPBF uses TSOT-23 packaging.
