Frequently Asked Questions
What output voltage does LT6658AHDE-1.2#TRPBF provide, and how precise is it for ADC reference use?
LT6658AHDE-1.2#TRPBF delivers a 1.2 V reference output with a maximum output voltage of 1.2006 V. The high-accuracy trim and low temperature coefficient make it suitable as a reference for 16-bit and 24-bit ADCs where even a few hundred microvolts of error can reduce effective resolution in precision measurement systems.
How many outputs does LT6658AHDE-1.2#TRPBF provide, and can they power different loads independently?
The device features 2 independent regulated outputs, allowing designers to drive separate analog loads such as an ADC reference and a DAC reference from a single IC. Each output is independently buffered, so load transients on one channel have minimal effect on the other, which is important in mixed-signal systems with 16-bit or better resolution requirements.
What package does LT6658AHDE-1.2#TRPBF use, and how does its thermal performance compare to SOIC alternatives?
The part is housed in a 16-pin DFN (R-PDSO-N16) package, which features an exposed thermal pad on the bottom that significantly reduces junction-to-board thermal resistance compared to SOIC-16 without an exposed pad. For high-current reference applications, the DFN's lower thermal resistance helps maintain output accuracy by reducing self-heating-induced drift.
Is LT6658AHDE-1.2#TRPBF suitable for new designs given its lifecycle status, and what is the projected supply horizon?
With a YTEOL of approximately 8.5 years from the 2019 introduction date, the part has an active supply outlook through roughly 2027 to 2028. The device is RoHS-compliant per JESD-609 e3, making it eligible for regulated markets. Buyers building long-lifecycle products should confirm distributor stock and negotiate blanket orders to lock pricing over multi-year production windows.
