Maxim DS2450S

161k4Односторонний5V5V-40°C ~ 85°C

Overview

Four high-impedance inputs to measure analog voltages over the 1-Wire bus ß User programmable input range (2.56V, 5.12V), resolution (1 to 16 bits) and alarm thresholds ß 5V, single supply operation ß Very low power: 2.5 mW active, 25 mW idle ß Built-in multidrop controller allows multiple DS2450’s to be identified and operated on a common 1-Wire bus ß Responds to Conditional Search if the analog voltage crosses the alarm thresholds ß Channels not used as analog input can serve as open drain digital outputs for closed-loop control ß Directly connects to a single port pin of a microprocessor and communicates at up to 16.3k bits per second ß Overdrive mode boosts communication speed to 142k bits per second ß On-chip 16-bit CRC-generator for safeguarding data transfers ß Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48- bit serial number 8-bit CRC tester) assures absolute traceability because no two parts are alike ß 8-bit family code specifies device communication requirements to bus master ß Operating temperature range from -40°C to +85°C ß Compact, low cost 8-pin SOIC surface mount pack

An on-chip CRC16 generator protects the communication against transmission errors when reading through the end of a memory page as well as when writing individual bytes.
