It accepts both differential and single-ended inputs through a single channel, with an internal S/H stage ahead of the converter core. The parallel data interface keeps latency low — useful for imaging, radar, or communications receivers where sample-to-output delay matters. The pipelined architecture delivers 14-bit resolution at 40 MSps without the power penalty of a flash converter, making it a fit for mid-speed instrumentation and IF-sampling chains. ## Supply rails and reference flexibility Both the analog and digital supplies run from 2.7 V to 3.4 V. The reference can be driven externally or generated internally. ## Package and thermal handling Housed in a 32-lead WFQFN with exposed pad (5x5 mm body), the LTC2247IUH#PBF is a surface-mount part that needs a thermal via pattern under the pad to pull heat into the ground plane. The exposed pad is the primary thermal path — at 40 MSps continuous conversion the die dissipates enough that a bare footprint without vias will push junction temperature above the 85°C operating limit in still air. The 32-QFN footprint is compact enough for multi-channel arrays where board area is tight. ## Temperature grade and environment Rated for -40°C to 85°C operating temperature, this part suits outdoor telecom cabinets, factory-floor data acquisition, and engine-bay-adjacent electronics that see thermal cycling. The industrial range covers most applications that aren't full military or downhole — if your system lives inside a conditioned lab or office, the commercial-grade sibling (if one exists) would also work, but the IUH suffix already carries the wider range. ## Lifecycle and sourcing reality Listed as Active and ROHS3 compliant.","metaTitle":"LTC2247IUH#PBF 14-bit ADC, 40 MSps, Pipelined, 32-QFN","metaDescription":"LTC2247IUH#PBF is a 14-bit pipelined ADC sampling at 40 MSps.
