LT6656BIS6-4.096#TRPBF

Voltage Reference Overview

The LT6656BIS6-4.096#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc., featuring a fixed output of 4.096V. It operates within an industrial temperature range of –40°C to 85°C and offers high accuracy with an initial error of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device draws a typical supply current of 1µA, supporting ultralow power consumption for battery-operated applications. It provides a minimum output drive current of 5mA with a dropout voltage as low as 10mV. Packaged in a 6-lead TSOT-23, it accepts input voltages up to 18V and includes reverse input protection.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for portable instrumentation
• High accuracy with specified initial error and temperature drift limits
• Capable of sourcing up to 5mA output drive current
• Operates with minimal dropout voltage relative to the output level

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the B grade designation corresponds to the required 0.1% accuracy and 20ppm/°C drift specifications for your application. Ensure the TSOT-23 package dimensions fit the target PCB layout constraints.

Voltage Reference Selection Notes

Select this component when a stable 4.096V reference is needed with strict power budgeting. The B grade offers a balance between cost and performance for general industrial use. Consider the LS8 package if long-term stability below 15ppm/√kHr is critical, or the DC package for alternative footprint requirements.

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 like the AIS6 and ACS6, differing primarily in temperature grade and accuracy class. The family supports multiple output voltages including 1.25V, 2.5V, and 5V options across various packages.
