LT1460 Micropower Precision Series Reference Family Features Description n Trimmed to High Accuracy: 0.075% Max The LT®1460 is a micropower bandgap reference that n Low Drift: 10ppm/°C Max combines very high accuracy and low drift with low power n Industrial Temperature Range dissipation and small package size. This series reference n Temperature Coefficient Guaranteed to 125°C uses curvature compensation to obtain low temperature n Low Supply Current: 130µA Max (LT1460-2.5) coefficient and trimmed precision thin-film resistors to n Minimum Output Current: 20mA achieve high output accuracy. The reference will supply n No Output Capacitor Required up to 20mA with excellent line regulation characteristics, n Reverse Battery Protection making it ideal for precision regulator applications. n Minimum Input/Output Differential: 0.9V This series reference provides supply current and power n Available in S0-8, MSOP-8, PDIP-8, TO-92 and dissipation advantages over shunt references that must idle SOT- 23 Package the entire load current to operate. Additionally, the LT1460 does not require an output compensation capacitor, yet applications is stable with capacitive loads. This feature is important where PC board space is a premium or fast settling is n Handheld Instruments demanded. In the event of a reverse battery connection, n Precision Regulators these references wil not conduct current, and are therefore n A/D and D/A Converters protected from damage. n Power Supplies n Hard Disk Drives The LT1460 is available in the 8-lead MSOP, SO, PDIP and the 3-lead TO-92 and SOT23 packages.
