Four channels, small footprint, I²C bus
The DAC6574IDGS packs four 10-bit voltage-output DACs into a 10-VSSOP package, each channel settling to 0.5 LSB in 9 µs over I²C.
What the 10-bit resolution and 9 µs settling mean on the bench
10 bits gives you 1024 steps across the supply range — at 5 V that is about 4.88 mV per LSB. The INL is ±0.5 LSB and DNL is ±0.1 LSB, so the output lands within half a step of the ideal value across all codes. 9 µs settling to ±0.5 LSB means you can update all four channels at roughly 110 kHz before the output hasn't finished moving — fine for setpoint control, trimming, or audio bias, but not for waveform synthesis above audio band.
Package and board-fit — 10-VSSOP, hand-solderable
Supplied in a tube; the surface-mount footprint is standard for MSOP-10, so existing board layouts for that footprint accept this part without a spin.
