LT6658BHDE-1.2#PBF

Overview

The LT6658BHDE-1.2#PBF is a precision dual output voltage reference from Analog Devices, operating at a fixed 1.2V output with B-grade specifications. It features an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device operates within a junction temperature range of -40°C to +125°C and utilizes a 16-lead (4mm × 3mm) plastic DFN package with an exposed thermal pad.

Feature Summary

• Dual outputs provide identical precision specifications and track each other over temperature and load variations.
• Combines the performance of a low drift, low noise voltage reference with that of a linear regulator.
• Outputs are configurable via external resistors to provide voltages up to 6V.

Applications

• Microcontroller or FPGA systems with integrated ADC/DAC
• Data acquisition systems requiring high precision
• Automotive control and monitoring circuits

Procurement Notes

Verify the specific suffix #PBF indicates RoHS compliance. Confirm the DE package designation matches the required 16-lead DFN footprint. Ensure the BHDE code corresponds to the correct B-grade accuracy and H-grade extended temperature range for your design requirements.

Selection Notes

Select this part when dual isolated supplies are needed for sensitive analog front ends. The separate supply pins allow for optimized power consumption and buffer isolation. Verify input voltage headroom meets dropout requirements for the intended load current.

Part Context

This component belongs to the LT6658 family of Refulators™, designed to replace discrete reference and regulator combinations. It serves as a direct replacement for standard single-output references in applications demanding higher current drive capabilities and improved channel-to-channel tracking.

Replacement Considerations

LT6658AHDE-1.2#PBF offers A-grade accuracy and lower drift.

FAQ

How does the OD pin function?

The OD pin provides a shutdown feature to reduce power consumption by disabling the internal circuitry when driven to a logic low state.

What is the purpose of the NR pin?

The NR pin allows users to band-limit and lower the total integrated output noise by connecting a capacitor.
