TLV5614CPW

Digital To Analog Converters Overview

The TLV5614CPW is a quadruple 12-bit voltage output digital-to-analog converter (DAC) housed in a 16-pin TSSOP package. It operates on dual independent supplies ranging from 2.7 V to 5.5 V, supporting separate digital and analog power domains. The device features a flexible 4-wire serial interface compatible with TMS320, SPI, QSPI, and Microwire protocols. Settling time is programmable between 3 µs and 9 µs via control bits within the 16-bit serial word. It includes internal reference buffers for REFINAB and REFINCD inputs, allowing different reference voltages for DAC pairs A/B and C/D.

Digital To Analog Converters Feature Summary

• Programmable settling time allows optimization of speed versus power dissipation through software control bits.
• Dual supply architecture enables independent operation of digital logic and analog output stages.
• Integrated high-impedance reference buffers reduce drive requirements for external reference sources.
• Rail-to-rail Class AB output buffers provide x2 gain relative to the reference input voltage.

Digital To Analog Converters Applications

• Battery powered test instruments
• Digital offset and gain adjustment circuits
• Industrial process controls
• Machine and motion control devices

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CPW' corresponds to the commercial temperature range (0°C to 70°C) and TSSOP packaging. Confirm that the component meets RoHS standards if required by the target assembly process. Ensure the design accounts for the separate DVDD and AVDD pin connections as specified in the datasheet electrical characteristics.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit channels are required in a single package. The TLV5614C variant is suitable for commercial environments operating between 0°C and 70°C. For industrial applications requiring extended temperature ranges, consider the TLV5614I series instead. Verify that the serial interface timing matches the host microcontroller's capabilities.

Digital To Analog Converters Part Context

The TLV5614 belongs to Texas Instruments' low-power, quad-channel DAC family. The 'C' designation indicates the commercial temperature grade, while 'PW' specifies the plastic small-outline thin package. This part serves as a direct replacement for older quad DAC solutions requiring serial programming and low standby current consumption.

Digital To Analog Converters Replacement Considerations

TLV5614IPW: Industrial temperature grade (-40°C to 85°C). TLV5614CD: Commercial grade SOIC package. TLV5614ID: Industrial grade SOIC package. All variants share identical electrical specifications and pinouts.

Digital To Analog Converters FAQ

Can the digital and analog supplies be tied together?

Yes, the DVDD and AVDD pins can be connected to the same voltage source, provided the voltage remains within the 2.7 V to 5.5 V range.

What determines the maximum serial clock frequency?

The maximum serial clock frequency is determined by the minimum pulse durations of SCLK high and low times, resulting in a maximum rate of 20 MHz.

How is simultaneous update of all DAC outputs achieved?

Simultaneous updates are controlled by the LDAC pin. When LDAC is low, DAC outputs update upon data loading; holding it high prevents updates until it is pulled low.
