LT1461CCS8-3.3#PBF

Voltage Reference Overview

The LT1461CCS8-3.3#PBF is a micropower precision low dropout series voltage reference manufactured by Analog Devices Inc. It provides a fixed 3.3V output with an initial accuracy of ±0.08% and a temperature coefficient of 12ppm/°C. The device operates within a commercial temperature range of 0°C to 70°C and draws a typical supply current of 35µA. It features a maximum input voltage of 20V, a minimum dropout voltage of 300mV at full load, and can source up to 50mA of output current. The component is housed in an 8-lead plastic SO package.

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging when sourcing. Confirm the CCS8 designation corresponds to the C-grade specifications (±0.08% accuracy, 12ppm/°C) and commercial temperature range (0°C to 70°C). Ensure the ordering part number matches the required 3.3V output option within the LT1461 family.

Voltage Reference Selection Notes

Select this component for applications requiring a stable 3.3V reference with moderate precision requirements. The C-grade offers a balance between cost and performance, suitable for general-purpose systems where ±0.08% accuracy is sufficient. Consider the A or B grades if tighter tolerance or lower temperature coefficients are needed for higher resolution data conversion systems.

Voltage Reference Part Context

This part belongs to the LT1461 family of micropower precision low dropout series voltage references. The family includes various output voltages (2.5V, 3V, 3.3V, 4.096V, 5V) and accuracy grades (A, B, C, D). The CCS8 variant specifically denotes the C-grade accuracy level packaged in an 8-lead SOIC format, designed for commercial temperature operation.
