What this dual 12-bit DAC brings to the BOM
The TLV5618ACDRG4 is a dual 12-bit voltage-output DAC from Texas Instruments, built on a String DAC architecture and communicating over an SPI data interface. The 10 µs settling time means the output voltage reaches its final value within 0.5 LSB in that window — fast enough for audio-level control loops, sensor bias trimming, and set-point generation in power supplies, but not for high-speed waveform synthesis.
Supply rails and reference — what the board needs
The reference input is external — the board must provide a clean reference voltage; the DAC's output span and accuracy are directly tied to that reference's stability and noise. The ±2 LSB INL and ±0.5 LSB DNL are typical for a 12-bit String DAC at this price point, and the DNL spec of ±0.5 LSB guarantees monotonicity across codes — no missing codes when sweeping the digital input.
