Eight-channel 12-bit trim DAC with I²C bus
The LTC2657CUFD-L12#PBF from Analog Devices packs eight 12-bit voltage-output DACs into a 20-lead QFN package, communicating over a single I²C bus. Each channel delivers a buffered output with ±0.5 LSB INL and ±0.1 LSB DNL — the tight linearity makes it a fit for trimming bias levels or setting reference voltages in multi-channel systems where monotonicity matters across the full code range.
Typical settling time is 3.9 µs to ±1 LSB, which is fast enough for most closed-loop trim updates or waveform generation below 100 kHz per channel. The Tube delivery means the part ships in anti-static tubes, not tape-and-reel, which matters for automated pick-and-place line setup — verify the feeder compatibility.
