Sampling at 8 kSPS with an SPI data interface, it keeps the digital side simple — no parallel bus, no external timing logic — just a few wires to the host MCU's SPI port. ## Single 5V rail and industrial temperature range simplify power and placement Both analog and digital supplies run from a single 5V rail, so no separate 1.8V or 3.3V domain is needed for the ADC core — one clean 5V supply with a low-noise LDO feeds the whole device. ## Active lifecycle and ROHS3 compliance — no supply chain surprises ROHS3 compliant (exemptions-free), it passes EU and global environmental requirements without a waiver — no special handling or documentation overhead at the BOM level.","metaTitle":"LTC2449IUHF#PBF 24-bit Sigma-Delta ADC, 8kSPS, 38-QFN","metaDescription":"Active Analog Devices 24-bit sigma-delta ADC, 8kSPS, 8 differential/16 SE inputs, SPI, 38-QFN, -40 to 85°C.

It samples at 15.4 kSPS vs 8 kSPS and operates up to 105°C, but the pinout and package differ — the AD7738BRUZ comes in a 28-TSSOP, not the 38-QFN.

It is supplied in tube packaging."},{"question":"What is the input type and channel count of the LTC2449IUHF#PBF?","answer":"It accepts both differential and single-ended inputs. In differential mode it handles 8 channels; in single-ended mode it handles 16 channels via an internal MUX feeding a single ADC core."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC2449IUHFPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC2449IUHFPBF when reusing this data.
