Overview
The SPX385AM1-L-1.2/TR is a micropower two-terminal bandgap voltage reference manufactured by MaxLinear (formerly Sipex). It provides a stable reference voltage of 1.2V with a wide operating current range from 10uA to 20mA. The device utilizes low temperature coefficient thin film resistor processes and laser trimming at the wafer level for high stability. It is housed in a 4-pin (3+Tab) SOT-89 package.
Feature Summary
- Micropower two-terminal bandgap architecture
- Wide operating current range from 10uA to 20mA
- High stability via low temperature coefficient thin film resistors
- Laser trimmed output voltage at wafer level
Applications
- Voltage reference circuits powered by 1.5V batteries
- Precision measurement systems requiring stable references
- Portable electronic devices with battery operation
Procurement Notes
Verify the manufacturer designation, as the component may be listed under MaxLinear following corporate acquisitions. Confirm the specific suffix 'L' indicates lead-free compliance if required by project specifications. Ensure the SOT-89 package type matches the PCB footprint design constraints before finalizing procurement orders.
Selection Notes
Select this component when a stable, low-power voltage reference is needed for battery-powered applications. The wide operating current range allows flexibility in circuit design across varying load conditions. Consider the thermal performance of the SOT-89 package for heat dissipation requirements in enclosed environments.
Part Context
This part belongs to the SPX385 series of voltage references, designed for precision applications requiring minimal power consumption. The series includes various packages and voltage options, with the AM1 variant specifically utilizing the SOT-89 form factor for surface-mount assembly needs in compact electronic designs.
Replacement Considerations
Check for direct equivalents within the MaxLinear portfolio such as the SPX385N-1.2/TR for through-hole alternatives. Verify pinout compatibility and thermal characteristics when substituting with other bandgap references from different manufacturers.
