LT1460 Micropower Precision Series Reference Family Fserutae Dnoitpircse 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 125C uses curvature compensation to obtain low temperature n Low Supply Current: 130A 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 is stable with capacitive loads. This feature is important a p p snoitacil 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 will not conduct current, and are therefore n A/D and D/A Converters protected from damage. n Power Supplies n The LT1460 is available in the 8-lead MSOP, SO, PDIP and Hard Disk Drives the 3-lead TO-92 and SOT23 packages.
