The SAR architecture gives you deterministic conversion latency — no pipeline delay — which matters when you are multiplexing several analog channels and need a settled result per channel before switching. The SPI data interface keeps the digital side clean: three or four wires to the host MCU, no parallel bus routing. With a 5 V analog and digital supply, this part fits into existing 5 V signal-chain designs without a separate rail for the ADC core. ## Industrial temperature range and package fit Rated from -40°C to 85°C, the LTC1609ISW#PBF covers the industrial temperature grade — suitable for motor-drive feedback, outdoor instrumentation, and factory-automation I/O modules where the ambient can swing well beyond commercial limits. The 20-SOIC (7.50 mm width) wide-body package is a standard footprint for multi-channel isolation or high-voltage spacing on the board. Supplied in Tube, which is the typical handling format for hand-assembly or low-volume production runs. ## Sourcing and lifecycle For BOM planning, the active status removes the urgency to qualify a drop-in replacement today, though it is always prudent to maintain a second-source option for long-life designs.","metaTitle":"LTC1609ISW#PBF 16-bit SAR ADC, 200k SPS, SPI, SOIC-20","metaDescription":"LTC1609ISW#PBF 16-bit SAR ADC from Analog Devices, 200k sampling rate, SPI interface, single-ended input, industrial temp range, SOIC-20 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Input Type":"Single Ended","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"16","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-SO","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"200k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$38.74","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$38.74000","currency":"USD"},{"qty":10,"price":"$36.14600","currency":"USD"},{"qty":38,"price":"$34.63079","currency":"USD"},{"qty":114,"price":"$31.38421","currency":"USD"},{"qty":266,"price":"$30.30203","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/1609fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the resolution and sampling rate of LTC1609ISW#PBF?","answer":"The LTC1609ISW#PBF is a 16-bit SAR ADC with a maximum sampling rate of 200k samples per second.
