That is eight trim voltages or bias levels from a part that fits in the footprint of a small op-amp — useful for multi-channel calibration, VCO tuning, or setting thresholds across a mixed-signal board. Each channel settles in 3.5 µs typical. The supply range spans 2.7 V to 5.5 V on both analog and digital rails. Integral nonlinearity is ±0.05 LSB maximum, and differential nonlinearity is ±0.5 LSB maximum — tight numbers that guarantee monotonicity and keep the transfer function within a fraction of an LSB across the full 8-bit range. ## Reference flexibility: internal or external The part accepts either the internal reference or an external reference applied to the REF pin. Using the internal reference saves a component and board area; switching to an external reference lets you tie the full-scale voltage to a system-level precision reference, which can improve drift and absolute accuracy across temperature. ## Temperature grade and operating environment Rated for -40°C to 85°C, the LTC2637IMS-LMX8#PBF covers industrial control, telecom infrastructure, and outdoor equipment. The 16-MSOP package is surface-mount, suitable for reflow assembly on standard FR4. ## Lifecycle and compliance The part carries an active lifecycle status — no last-time-buy or NRND flags — and is ROHS3 compliant. That means it remains a current-production choice for new designs and ongoing production, with no imminent obsolescence risk.","metaTitle":"LTC2637IMS-LMX8#PBF 8-Channel 8-Bit DAC, I²C, 16-MSOP","metaDescription":"LTC2637IMS-LMX8#PBF 8-bit 8-channel voltage-output DAC from Analog Devices.
