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.","metaTitle":"LTC2657CUFD-L12#PBF 12-Bit 8-Ch DAC, I²C, 20-QFN","metaDescription":"LTC2657CUFD-L12#PBF 12-bit 8-channel voltage-output DAC, I²C interface, ±0.5 LSB INL, 3.9 µs settling, 20-QFN.

The AD5629 uses a String DAC architecture and has a 7 µs settling time (vs 3.9 µs) and a wider -40°C to 105°C temperature range. The LTC2657 is the faster, tighter-DNL option for commercial-temperature designs; the AD5629 covers extended temperature and is available in a different package (20-LFCSP).
