TLV5619IPWRG4

Digital To Analog Converters Overview

The TLV5619IPWRG4 is a 12-bit, single-channel digital-to-analog converter (DAC) manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features a parallel interface compatible with microprocessors and TMS320 DSPs. The device utilizes a resistor-string architecture with double-buffered input registers, allowing asynchronous updates via the LDAC pin. It includes an internal power-on reset and a rail-to-rail output buffer amplifier with x2 gain. Power consumption is 8 mW at 5 V and 4.3 mW at 3 V, reducible to 50 nW in power-down mode. The component is housed in a 20-pin TSSOP package.

Digital To Analog Converters Feature Summary

• Double-buffered 12-bit parallel data interface for flexible system integration
• Rail-to-rail buffered analog output stage with x2 gain capability

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'G4' indicates compliance with RoHS directives and lead-free manufacturing standards as per Texas Instruments documentation. Confirm the operating temperature range corresponds to the 'I' grade (-40°C to 85°C) and that the package type matches the required PCB layout dimensions for the 20-pin TSSOP outline.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, 12-bit resolution is required with low power consumption. Ensure the design supports a parallel interface and requires an asynchronous update mechanism. Verify that the supply voltage range of 2.7 V to 5.5 V aligns with the system power rails and that the TSSOP-20 package fits the mechanical constraints.

Digital To Analog Converters Part Context

This part belongs to the TLV5619 family of 12-bit DACs. Variants include the CDW/IPW series for commercial/industrial temperatures and the QDW series for automotive applications. The IPWRG4 designation specifies the industrial temperature range, TSSOP packaging, tape-and-reel shipping, and environmental compliance.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include TLV5619IDWR and TLV5619IPW. Cross-family replacements require verification of pin compatibility and electrical specifications against the original datasheet requirements.
