TLV5619IPW

Digital To Analog Converters Overview

The TLV5619IPW is a 12-bit voltage output digital-to-analog converter (DAC) manufactured by Texas Instruments, housed in a 20-pin TSSOP package. It operates on a single supply ranging from 2.7 V to 5.5 V and features a microprocessor-compatible parallel interface with double-buffered data inputs. The device includes an internal power-on reset and a rail-to-rail buffered output amplifier with Class A topology for improved stability. Key electrical specifications include ±0.4 LSB differential nonlinearity (DNL), ±1.5 LSB integral nonlinearity (INL), and a typical settling time of 1 µs. Power consumption is 8 mW at 5 V and 4.3 mW at 3 V, reducible to 50 nW in power-down mode.

Digital To Analog Converters Feature Summary

• Features a 12-bit resistor string architecture with a rail-to-rail buffered output stage.
• Supports asynchronous updates via the LDAC pin using double-buffered input registers.
• Includes internal power-on reset logic to initialize latches upon startup.
• Offers low-power operation with a dedicated power-down mode controlled by the PD pin.

Digital To Analog Converters Applications

• Battery-powered test instruments
• Digital offset and gain adjustment circuits
• Machine and motion control devices
• Cordless and wireless telephones

Digital To Analog Converters Procurement Notes

Verify that the component matches the specific industrial temperature range (-40°C to 85°C) indicated by the 'I' suffix in the part number TLV5619IPW. Confirm the package type is TSSOP (PW) rather than SOIC (DW). Ensure the source documentation aligns with the Texas Instruments datasheet SLAS172F for accurate parameter validation.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with a parallel interface is required for single-supply applications. The TLV5619IPW is suitable for designs needing a buffered output capable of driving loads up to 10 kΩ without external amplification. Consider the -40°C to 85°C operating range for industrial environments where higher precision or different interfaces may necessitate alternative models.

Digital To Analog Converters Part Context

Originally developed by Burr Brown before its acquisition by Texas Instruments, the TLV5619 belongs to a family of low-power DACs. The IPW variant specifically denotes the industrial temperature grade and TSSOP packaging. This component serves as a bridge between digital control systems and analog signal generation, often interfacing directly with microprocessors or DSPs requiring precise voltage control.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers include TLV5619CDWRG4 and TLV5619IDWRG4. Verify compatibility regarding package dimensions and lead finish when substituting these variants.

Digital To Analog Converters FAQ

How does the TLV5619 handle data updates?

The device uses double-buffered input registers. Data is latched on the positive edge of the WE signal, and the DAC output is updated asynchronously when the LDAC pin is driven low.

What is the maximum reference voltage allowed?

The reference input voltage (REFIN) can range from 0 V up to VDD minus 1.5 V. For a 5-V supply, the maximum is approximately 3.5 V, though typical operation uses lower values like 2.048 V.

Can the output drive capacitive loads?

Yes, the output is specified to drive a load capacitance of up to 100 pF while maintaining stability due to the Class A output stage design.
