LTC2000IY-14#PBF

Digital To Analog Converters Overview

The LTC2000IY-14#PBF is a 14-bit, 2.5Gsps current steering digital-to-analog converter (DAC) from Analog Devices Inc., designed for industrial temperature ranges (-40°C to 85°C). It features exceptional spectral purity with an SFDR of >68dBc from DC to 1GHz and operates at update rates up to 2.5Gsps in dual-port mode or 1.25Gsps in single-port mode. The device utilizes a source-synchronous LVDS interface supporting data rates up to 1.25Gbps. Key electrical specifications include a nominal full-scale output current of 40mA, adjustable between 10mA and 60mA, and an output compliance range of ±1V. Power consumption is 2.2W at 2.5Gsps and 1.3W at 1.25Gsps, powered by 1.8V and 3.3V supplies.

Digital To Analog Converters Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free packaging when sourcing. Confirm the 'I' grade corresponds to the required -40°C to 85°C industrial operating temperature range. Ensure the ordering information matches the 170-lead BGA package dimensions of 9mm x 15mm. Check for availability of design files and evaluation boards for system integration.

Digital To Analog Converters Selection Notes

Select this model for applications requiring high-speed DACs with strict linearity and low phase noise. The 14-bit resolution balances performance and complexity compared to 16-bit variants. Consider the power dissipation of 2.2W at full speed when designing thermal management solutions. Verify that the host system supports the required LVDS clocking and data input formats.

Digital To Analog Converters Part Context

This component belongs to the LTC2000 family, which includes 16-bit and 11-bit variants. The 'IY' designation specifies the industrial temperature grade and the 170-lead BGA package type. The '#PBF' suffix denotes a lead-free finish compliant with RoHS standards. All variants share the same pinout and core architecture but differ in resolution and specific AC performance metrics.

Digital To Analog Converters Replacement Considerations

LTC2000CY-14#PBF: Commercial temperature grade (0°C to 70°C). LTC2000IY-16#PBF: Higher 16-bit resolution. LTC2000IY-11#PBF: Lower 11-bit resolution.
