DAC161S055CISQ/NOPB

Digital To Analog Converters Overview

The DAC161S055CISQ/NOPB is a precision, single-channel, 16-bit digital-to-analog converter (DAC) manufactured by Texas Instruments. It utilizes an R-2R architecture and features a buffered voltage output. The device operates with an analog supply voltage range of 2.7V to 5.25V and a digital supply voltage range of 1.7V to 5.25V. It supports a 4-wire serial interface compatible with SPI. Key electrical specifications include a typical settling time of 5µs, a gain error of 0.05% FSR, and power consumption of 5.5mW. The component is housed in a 16-pin WQFN package with an exposed pad and is rated for operation between -40°C and +105°C.

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the ordering suffix matches the required tape-and-reel quantity or cut-tape availability. Confirm RoHS compliance status and moisture sensitivity level ratings prior to assembly planning to prevent soldering defects during reflow processes.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution voltage output is required without external amplification. Compare against other members of the DAC161S055 family for variations in pinout or packaging. Verify that the 4-wire serial interface timing constraints align with the host microcontroller's capabilities and that the operating temperature range meets the specific environmental conditions of the target application.

Digital To Analog Converters Part Context

This part belongs to the DAC161S055 series, which includes variants such as the DAC161S055CISQX/NOPB. The 'NOPB' suffix indicates lead-free and rohs-compliant construction. The device is functionally similar to other precision DACs in the industry but is distinguished by its specific R-2R architecture and integrated buffer design tailored for low-power, high-accuracy applications.

Digital To Analog Converters Replacement Considerations

The DAC161S055CISQX/NOPB is listed as a direct replacement for the discontinued DAC161S055CISQX. Verify pin compatibility and electrical parameters before substituting with other 16-bit DACs from different manufacturers.
