Digital-to-Analog Converter (DAC) TLC5620CN by Texas Instruments, 14‑pin PDIP package

The TLC5620CN by Texas Instruments is a digital-to-analog converter (DAC) supplied in a 14-pin PDIP package. It provides voltage output conversion from digital input codes to produce moderate-resolution analog signals. The device is intended for systems where a compact, through-hole DAC is required to interface microcontrollers, generate test signals, or perform level shifting between digital and analog domains.

Advantages

The TLC5620CN offers a simple parallel-input interface and a stable voltage output suited to typical mixed-signal applications. Its PDIP 14-pin package enables straightforward mounting on through-hole prototyping boards and legacy printed circuit boards. The device delivers predictable analog behavior across the operating range and is compatible with common single-supply voltage levels used in embedded systems.

Suitable for

• Microcontroller to analog signal interfacing
• Signal generation and waveform output in low- to moderate-resolution applications
• Level shifting and analog control in test equipment
• Educational and prototyping projects using through-hole components

Key specifications

• Function: Digital-to-analog voltage output conversion
• Package type: 14-pin PDIP (through-hole)
• Input interface: Parallel digital code inputs (logic-level compatible)
• Output type: Voltage output suitable for external buffering or direct use within specified load limits
• Supply: Single-supply operation compatible with common embedded voltages
• Resolution class: Moderate resolution suitable for control and test signals

How to use

Connect the device to a single supply voltage within the recommended operating range and tie reference and ground connections according to the circuit requirements. Apply digital input codes to the parallel input pins from a microcontroller or logic source while observing input voltage thresholds. Use an appropriate output buffer or amplifier if required by the load or to achieve lower output impedance. Include proper decoupling on the supply pins and follow Texas Instruments’ recommended layout practices for mixed-signal routing when integrating the DAC into a PCB.

Recommendations

For stable performance, place bypass capacitors close to the supply pins and route analog output traces away from noisy digital lines. Verify logic-level compatibility between the digital source and the DAC inputs, and add an output buffer when driving low-impedance loads or long cables.
