LT1461CCS8-4#TRPBF

Voltage Reference Overview

The LT1461CCS8-4#TRPBF is a micropower precision low dropout series voltage reference from Analog Devices, housed in an 8-lead plastic SO package. It provides a fixed 4.096V output with an initial accuracy of ±0.08% and a maximum temperature coefficient of 12ppm/°C over the commercial operating range of 0°C to 70°C. The device draws a typical supply current of 35µA and supports up to 50mA output drive current. It features a shutdown pin for power management and includes thermal limiting protection.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with low supply current and high output drive capability
• Utilizes advanced curvature compensation techniques and trimmed precision thin-film resistors
• Includes a shutdown feature to switch full load currents and enable system power down
• Incorporates thermal limiting to protect the part from overload conditions

Voltage Reference Applications

• A/D and D/A Converters
• Precision Regulators
• Handheld Instruments
• Power Supplies

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the CCS8 grade corresponds to the required ±0.08% accuracy and 12ppm/°C temperature coefficient specifications. Ensure the commercial temperature range of 0°C to 70°C meets the application requirements before procurement.

Voltage Reference Selection Notes

Select this part for applications requiring a stable 4.096V reference with micropower consumption. The 50mA output drive allows use in precision regulators where higher current is needed. Consider the thermal hysteresis effects if the device will undergo significant temperature cycling or high power dissipation during operation.
