Two 16-bit channels in a small footprint
The DAC8552IDGKTG4 is a dual 16-bit, voltage-buffered DAC from TI's microPOWER™ series. It packs two independent converters with a string-DAC architecture into an 8-VSSOP package, saving board area in multi-output precision control loops. Each channel settles to within 1 LSB in 10 µs, supporting update rates around 100 kSPS — fast enough for closed-loop servo positioning or low-frequency waveform generation.
Supply rails and interface — what to watch
The reference is external — the output span tracks the reference voltage directly, which means the reference noise and drift appear at the output. Data is clocked in via SPI or DSP-compatible serial interface. The 16-bit word loads into an input register and transfers to the DAC latch on the frame-sync rising edge. Integral nonlinearity is ±4 LSB max, differential nonlinearity ±0.35 LSB max — the DNL spec is tight enough that monotonicity is guaranteed over temperature.
