TLV5613CPW

Digital To Analog Converters Overview

The TLV5613CPW is a 12-bit voltage output digital-to-analog converter (DAC) manufactured by Texas Instruments. It operates on a single supply ranging from 2.7 V to 5.5 V with separate analog and digital power pins. The device features an 8-bit microcontroller-compatible parallel interface, utilizing address bits A0 and A1 for register selection. It includes a rail-to-rail output buffer with x2 gain. Settling time is programmable via the SPD bit: 1 µs in fast mode or 3.5 µs in slow mode. Power consumption is 4.2 mW in fast mode and 1.2 mW in slow mode. Differential nonlinearity is ±0.4 LSB, and integral nonlinearity is ±1.5 LSB. The component is housed in a 20-pin TSSOP package and supports an operating temperature range of 0°C to 70°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-20 package configuration required for your PCB layout. Confirm the 'C' suffix indicates the commercial temperature range of 0°C to 70°C, as opposed to the industrial grade variant. Ensure the datasheet revision matches your design requirements for timing parameters.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with a parallel interface is required for low-power applications. The separate AVDD and DVDD supplies allow for noise isolation between digital logic and analog outputs. Consider the programmable settling time if system power constraints are tighter than performance requirements.

Digital To Analog Converters Part Context

This part belongs to the TLV5613 series of 12-bit DACs. The CPW suffix specifically denotes the commercial temperature range version packaged in a Thin Shrink Small Outline (TSSOP) format. Other variants include the IDW and IPW models which support extended industrial temperature ranges.

Digital To Analog Converters Replacement Considerations

The TLV5613IDW serves as the industrial temperature range equivalent in the SOIC package. The TLV5613IPW provides the same electrical specifications but utilizes the TSSOP package for the industrial grade (-40°C to 85°C). Verify pin compatibility before substitution.

Digital To Analog Converters FAQ

How is the settling time controlled?

Settling time is controlled by the SPD bit within the control register or the physical SPD pin. Setting SPD to 1 selects fast mode (1 µs), while 0 selects slow mode (3.5 µs).

What is the function of the LDAC pin?

LDAC is an active-low input used to load the DAC output from the holding latches. It allows for asynchronous updates of the analog output voltage.

Can the analog and digital supplies be different voltages?

Yes, the device has separate AVDD and DVDD pins. However, the difference between them must not exceed 2.8 V, and both must remain within the 2.7 V to 5.5 V operating range.
