Each channel settles to within 1 LSB in 4.4 µs typical, which is fast enough for closed-loop trim loops or multi-channel set-point control without waiting on the bus. The I²C interface keeps the pin count low — four analog outputs plus the serial bus and a reference pin. Supply range runs from 2.7 V to 5.5 V on both the analog and digital rails. The reference can be either the internal bandgap or an external voltage fed into the REF pin. ## Temperature range and where it lands Rated for -40°C to 125°C, this is the H-grade version — it lives comfortably in engine-bay electronics, industrial oven controls, or outdoor telecom gear where the ambient inside the enclosure hits triple digits. The 16-QFN with exposed pad helps pull heat into the PCB ground plane. ## Linearity and monotonicity INL and DNL are both ±1 LSB maximum. That guarantees monotonicity across the full 12-bit range — every code step produces a positive voltage increment. For trim applications (power supply margining, VCO tuning, laser bias) this matters more than absolute accuracy; you need to know the output moves the right direction every time. ## Sourcing and lifecycle note Status is Active per the manufacturer, and the part carries ROHS3 compliance. No end-of-life notice is published.","metaTitle":"LTC2635HUD-LMO12#PBF 12-bit quad DAC, I²C, -40°C to 125°C","metaDescription":"LTC2635HUD-LMO12#PBF is an Analog Devices 12-bit quad voltage-output DAC with I²C interface, 4.4 µs settling, and -40°C to 125°C range.

Submit an RFQ for current availability and pricing."},{"question":"Does LTC2635HUD-LMO12#PBF require an external voltage reference?","answer":"No — it has an internal reference. You can also feed an external reference into the REF pin if you need a specific voltage or ratiometric operation."},{"question":"Is LTC2635HUD-LMO12#PBF compatible with 3.3V logic?","answer":"Yes. The digital supply range is 2.7 V to 5.5 V, so 3.3 V logic levels work directly.
