Overview
The LT6658BHDE-1.8#PBF is a precision dual output voltage reference from Analog Devices, housed in a 16-lead DFN package. It provides a fixed 1.8V output with an initial accuracy of ±0.1% and a temperature coefficient of 20 ppm/°C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum input voltage of 36V. Output 1 delivers up to 150mA sourcing current, while Output 2 provides up to 50mA.
Feature Summary
- Combines precision voltage reference performance with linear regulator capabilities for high-current driving.
- Features two independent outputs that track each other over temperature and load variations.
- Includes Kelvin sense connections on outputs to minimize load regulation errors.
- Offers separate supply pins for each output to allow power consumption reduction and buffer isolation.
Applications
- Dual output tracking reference systems
- Microcontroller or FPGA applications with integrated ADC/DAC
- Data acquisition systems
- Precision low noise regulators
Procurement Notes
Verify the specific suffix DE indicates the DFN package and H-grade denotes the extended temperature range. Confirm RoHS compliance via the PBF suffix. Check official distributor listings for current availability status as distribution may be restricted in certain regions.
Selection Notes
Select this part when dual isolated references are required with high current capability. The B-grade offers standard precision suitable for general instrumentation. Ensure the DFN package fits the thermal and footprint constraints of the design compared to MSOP alternatives.
Part Context
This component belongs to the LT6658 family of Refulators. It shares architectural similarities with MSOP variants but utilizes a DFN package for different thermal management characteristics. The BHDE designation specifically identifies the B-grade accuracy, 1.8V output, DFN package, and high-temperature operation.
Replacement Considerations
LT6658BHMSE-1.8#PBF (MSOP package equivalent)
FAQ
What is the maximum sourcing current for Output 1?
Output 1 can source up to 150mA.
Does the device support shutdown functionality?
Yes, the OD pin allows for shutdown control to reduce power consumption.
