LTC2641AIDD-16#PBF

Digital To Analog Converters Overview

The LTC2641AIDD-16#PBF is a 16-bit unbuffered voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7V to 5.5V supply with a typical current consumption of 120µA. The device features a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz. Key electrical specifications include ±1LSB INL and DNL over temperature, a settling time of 1µs to 16 bits, and a glitch impulse of 0.5nV·sec. It is housed in an 8-lead 3mm × 3mm DFN package and functions within an industrial temperature range of –40°C to +85°C.

Digital To Analog Converters Feature Summary

• 16-bit resolution with ±1LSB INL/DNL guaranteed over temperature
• Low power consumption of 120µA with 2.7V to 5.5V single supply operation
• Fast 1µs settling time and 0.5nV·sec glitch impulse
• 50MHz SPI/Microwire compatible serial interface with Schmitt-trigger inputs

Digital To Analog Converters Applications

• Process control and industrial automation systems
• Automatic test equipment
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'IDD' confirms the industrial temperature grade (–40°C to +85°C) and the 'A' grade for ±1LSB linearity. Confirm the '#PBF' suffix indicates lead-free finish and RoHS compliance. Ensure the DFN-8 package matches the PCB footprint requirements, noting the exposed pad must be soldered to ground.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high precision (±1LSB) in a compact 3mm × 3mm footprint. The unbuffered output requires loads greater than 60kΩ to maintain linearity; use an external buffer if driving lower impedances. Verify that the system interface supports the 3-wire synchronous protocol and that the reference voltage input range (2V to VDD) aligns with available reference sources.

Digital To Analog Converters Part Context

This part belongs to the LTC2641 family of 16-/14-/12-bit voltage output DACs. The 'A' designation specifies enhanced linearity performance compared to standard grades. The 'IDD' suffix denotes the industrial temperature range and DFN-8 packaging. It serves as a low-power alternative to buffered DACs in space-constrained embedded designs.
