TLV5621IDR

Digital To Analog Converters Overview

The TLV5621IDR is a low-power quadruple 8-bit digital-to-analog converter (DAC) from Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features four buffered voltage outputs. The device utilizes a resistor-string architecture with high-impedance reference inputs for each DAC channel. Digital control is managed via a simple 3-wire serial interface compatible with CMOS logic, supporting clock frequencies up to 1 MHz. The output range is programmable to either one or two times the reference voltage. Integral linearity error is specified at ±1 LSB maximum, while differential nonlinearity is ±0.9 LSB maximum. The unit is housed in a 14-pin SOIC package.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging details and material specifications. Ensure that the selected variant matches the required thermal performance and moisture sensitivity level for the intended assembly process. Cross-reference the part number with official availability status to confirm production lifecycle stage before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated analog outputs are required within a space-constrained design. The double-buffered mode is essential for applications demanding synchronized updates across all channels. Verify that the system supply voltage falls within the 2.7 V to 5.5 V operational range and that the serial interface timing requirements align with the microcontroller capabilities.

Digital To Analog Converters Part Context

This device belongs to the TLV562x family of low-power digital-to-analog converters. It shares architectural similarities with other members like the TLV5620 but provides four channels instead of one. The 'I' suffix denotes the industrial temperature range specification, while 'DR' indicates the tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers include TLV5621ED and TLV5621ID. These variants maintain functional equivalence but differ in packaging type. Verify pin compatibility and electrical specifications against the original datasheet before implementing any substitution in existing designs.
