Overview
The LTC2617IDE#PBF is a dual 14-bit rail-to-rail voltage output digital-to-analog converter (DAC) from Analog Devices Inc. Operating on a single supply of 2.7V to 5.5V, it features built-in high-performance output buffers and guaranteed monotonicity over temperature. The device utilizes a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. It incorporates double-buffered data latches, an asynchronous DAC update pin (LDAC), and a power-on reset circuit that defaults outputs to zero scale. Packaged in a compact 12-lead DFN (4mm × 3mm) format, it offers low power consumption with individual channel power-down capabilities.
Feature Summary
- Dual 14-bit resolution with rail-to-rail voltage outputs
- I²C serial interface with 27 selectable addresses
- Guaranteed monotonic operation over full temperature range
- Power-on reset to zero scale with <10mV glitch amplitude
Applications
- Mobile communications systems
- Process control and industrial automation
- Instrumentation and automatic test equipment
Procurement Notes
Verify the specific suffix #PBF indicates lead-free finish and tube packaging. Confirm the 'IDE' designation corresponds to the industrial temperature range of –40°C to 85°C. Ensure compatibility with the 12-lead DFN footprint during procurement planning.
Selection Notes
Select this model for applications requiring 14-bit precision with I²C connectivity. Compare against LTC2607 (16-bit) or LTC2627 (12-bit) if resolution requirements differ. Consider the LTC2617-1 variant if mid-scale power-on reset is required instead of zero scale.
Part Context
This component belongs to the LTC2607/LTC2617/LTC2627 family of dual DACs. They share identical pinouts and interfaces, differing primarily in resolution: 16-bit (LTC2607), 14-bit (LTC2617), and 12-bit (LTC2627). All variants utilize the same 12-lead DFN package and support the same I²C protocol.
Replacement Considerations
Direct functional substitutes within the same family include LTC2607IDE#PBF (higher resolution) and LTC2627IDE#PBF (lower resolution). For mid-scale power-on reset behavior, consider LTC2617IDE-1#PBF.
