LT6656ACS6-2.5#TRPBF

Voltage Reference Overview

The LT6656ACS6-2.5#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output voltage of 2.5V. It operates within an industrial temperature range of –40°C to 85°C and utilizes a 6-lead plastic TSOT-23 package. The device draws less than 1µA of supply current, with a typical value of 850nA, and supports a maximum input voltage of 18V. It provides an initial accuracy of 0.05% and a maximum temperature coefficient of 10ppm/°C. The component can source up to 5mA of output drive current and maintains stability with output capacitance of 1µF or larger.

Voltage Reference Feature Summary

• Ultralow supply current consumption for extended battery life in portable applications
• High accuracy with low temperature drift suitable for precision measurement systems
• Capable of operating with a supply voltage as close as 10mV above the output voltage
• Includes reverse input and output protection for robust circuit operation

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 components. Confirm that the 'A' grade designation corresponds to the required 0.05% initial accuracy and 10ppm/°C temperature coefficient specifications. Ensure the industrial temperature range rating meets the operational environment requirements of the target design.

Voltage Reference Selection Notes

Select this component for designs requiring minimal quiescent current alongside high precision. The TSOT-23 package offers a compact footprint for space-constrained PCB layouts. Consider the 10mV dropout characteristic for applications where the supply voltage closely matches the reference output level. Verify load regulation requirements against the specified ppm/mA limits under varying load conditions.

Voltage Reference Part Context

This part belongs to the LT6656 family of micro-power precision voltage references. The family includes various output voltage options and package types such as DFN and LS8. The ACS6 variant specifically denotes the commercial temperature grade in a TSOT-23 package, while the AIS6 variant covers the industrial range. This specific model targets applications needing stable references in low-power environments.
