LT6656ACS6-3.3#TRPBF

Voltage Reference Overview

The LT6656ACS6-3.3#TRPBF is a precision series voltage reference providing a fixed 3.3V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. It operates within the commercial temperature range of 0°C to 70°C and draws less than 1µA of supply current, typically 850nA. The device supports up to 5mA of output drive current and functions with a supply voltage as low as VOUT + 10mV, accepting inputs up to 18V. Packaged in a 6-lead TSOT-23, it requires a minimum 1µF output capacitor for stability.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications
• High accuracy with minimal temperature drift over specified ranges
• Capable of sourcing significant load current while maintaining regulation
• Operates with minimal dropout voltage relative to the output level

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) references
• Portable gas monitors
• Battery- or solar-powered systems
• Micropower remote sensing

Voltage Reference Procurement Notes

Verify that the specific part number suffix matches the required temperature grade and package type. Confirm the ordering suffix corresponds to tape and reel packaging rather than cut tape or mini-reel variants. Ensure the component meets RoHS compliance standards if required by the manufacturing process. Cross-reference the manufacturer's latest documentation for any updates to pin configurations or electrical specifications.

Voltage Reference Selection Notes

Select this component when high precision is required alongside extremely low power consumption. The A-grade specification ensures tight tolerance limits for critical measurement circuits. Consider the thermal environment carefully, as the commercial grade is limited to 70°C. Evaluate the load requirements to ensure the 5mA drive capability aligns with the application's peak current demands without exceeding stability limits.

Voltage Reference Part Context

This component belongs to the LT6656 family of micropower precision voltage references from Analog Devices. The family includes various output voltages and grades, such as the B-grade for lower accuracy or industrial temperature ranges. The S6 suffix indicates the 6-lead plastic TSOT-23 package, distinguishing it from DFN or LS8 options. This specific variant targets cost-sensitive commercial applications requiring stable reference voltages.
