TLV5613CDWR

Digital To Analog Converters Overview

The TLV5613CDWR is a 12-bit voltage output digital-to-analog converter (DAC) featuring an 8-bit microcontroller-compatible parallel interface. It operates on a single supply ranging from 2.7 V to 5.5 V with separate analog and digital power pins. The device utilizes a resistor-string architecture buffered by a rail-to-rail x2 gain output stage. Key electrical parameters include ±0.4 LSB differential nonlinearity (DNL), ±1.5 LSB integral nonlinearity (INL), and a programmable settling time of 1 µs in fast mode or 3.5 µs in slow mode. Power consumption is 4.2 mW in fast mode, 1.2 mW in slow mode, and 50 nW in power-down mode.

Digital To Analog Converters Feature Summary

• Features a rail-to-rail output buffer with x2 gain for wide dynamic range.
• Includes programmable speed control to optimize the trade-off between settling time and power dissipation.
• Supports asynchronous or synchronous DAC updates via dedicated hardware control pins.
• Integrates a low-power shutdown mode for battery-operated applications.

Digital To Analog Converters Procurement Notes

Verify the 'R' suffix indicates tape-and-reel packaging rather than tube packaging when sourcing this specific part number. Confirm the operating temperature range matches the 'C' designation (0°C to 70°C). Ensure the component source provides valid traceability documentation consistent with Texas Instruments production standards.

Digital To Analog Converters Selection Notes

Select this component for designs requiring a 12-bit resolution with a parallel interface. Consider the separate AVDD and DVDD pins if noise isolation is required. Evaluate the fast versus slow mode requirements based on system settling time constraints and available power budget.

Digital To Analog Converters Part Context

This device belongs to the TLV5613 family of 12-bit CMOS DACs manufactured by Texas Instruments. The CDWR variant specifically denotes the commercial temperature grade housed in a SOIC-20 package and supplied in a tape-and-reel format for automated assembly processes.

Digital To Analog Converters Replacement Considerations

Compatible alternatives within the same series include the TLV5613IDWR for industrial temperature ranges. Other pin-compatible options may exist but require verification of interface timing and electrical specifications against the original design requirements.

Digital To Analog Converters FAQ

How is the settling time controlled?

Settling time is controlled via the SPD bit in the control register or the physical SPD pin. Setting it to logic high enables fast mode (1 µs), while logic low enables slow mode (3.5 µs).

What is the maximum reference voltage allowed?

The reference input voltage can range from ground up to AVDD minus 1.5 V. Exceeding this limit may cause clipping of the transfer function due to the x2 output buffer gain.

Can the DAC update be synchronized?

Yes, the DAC update can be synchronized using the LDAC pin. Alternatively, asynchronous updates are possible by controlling the RLDAC bit in the control register.
