Overview
The LT6658AIDE-1.2#PBF is a precision dual output voltage reference from Analog Devices, packaged in a 16-lead (4mm × 3mm) plastic DFN with an exposed thermal pad. It provides a fixed 1.2V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device operates within a junction temperature range of –40°C to 85°C and supports input voltages up to 36V. Output 1 delivers up to 150mA sourcing current, while Output 2 provides up to 50mA.
Feature Summary
- Combines the performance of a precision voltage reference and a linear regulator for simultaneous high-resolution ADC/DAC driving and microcontroller powering.
- Features Kelvin sense connections on outputs to achieve low load regulation under heavy loading conditions.
- Includes separate supply pins for each output to allow power consumption reduction and buffer amplifier isolation.
Applications
- Microcontroller or FPGA systems with integrated ADC/DAC
- Data acquisition systems requiring stable references
- Automotive control and monitoring circuits
Procurement Notes
Verify the specific suffix #PBF indicates RoHS compliance when ordering. Confirm the package type matches the design footprint requirements. Check the manufacturer's latest documentation for any updates regarding the specified operating temperature range and electrical characteristics before finalizing procurement.
Selection Notes
Select this part for applications requiring dual independent outputs with matched tracking over temperature. Ensure the input voltage meets the minimum dropout requirements for the desired load current. Consider the DFN package for its thermal management capabilities compared to MSOP options.
Part Context
This component belongs to the LT6658 family of Refulators™, which integrate precision reference and regulator functions. The 'A' grade denotes high accuracy specifications, while 'IDE' identifies the 16-lead DFN package variant. It serves as a critical power management IC for signal chain integrity.
Replacement Considerations
LT6658BIDE-1.2#PBF offers similar functionality with relaxed accuracy and drift specifications.
FAQ
Can the output voltage be adjusted?
Yes, each output can be configured with external resistors to provide an adjustable output voltage up to 6V.
What is the purpose of the OD pin?
The OD pin allows for shutdown control to reduce power consumption by disabling the internal circuitry.
