LT6656ACDC-2.048#TRPBF

Voltage Reference Overview

The LT6656ACDC-2.048#TRPBF 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 range up 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
• High output drive current capability

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 sourcing. Confirm the AC grade designation corresponds to the required 0°C to 70°C specified temperature range for your application environment. Ensure the DFN package thermal characteristics are compatible with your PCB layout constraints.

Voltage Reference Selection Notes

Select this component when a fixed 2.048V reference is required in a compact surface-mount footprint. The AC grade offers a balance of cost and performance for commercial temperature ranges. Consider the LS8 package if long-term stability and humidity resistance are critical requirements over the wider industrial temperature range.

Voltage Reference Part Context

This part belongs to the LT6656 family of 1µA precision series voltage references. The DC suffix identifies the 6-lead DFN package variant, distinguishing it from the TSOT-23 and hermetic LS8 options. The AC grade specifies the commercial temperature operating range, while the AI grade would be selected for extended industrial temperatures.
