Analog-to-Digital Converters

Tue, 09/02/2003 - 8:42am

Maxim introduces the MAX1226-MAX1231 and MAX1026-MAX1031 families of 12- and 10-bit analog-to-digital converters (ADCs) with 8, 12, or 16 single-ended analog inputs or 4, 6, or 8 true-differential analog inputs. These devices minimize microprocessor I/O requirements by including an on-chip FIFO, scan mode, internal clock mode, and internal averaging. An on-board ۫°C accurate temperature sensor provides local temperature. This reduces cost and saves board space. The MAX1226/MAX1228/MAX1230 and MAX1026/MAX1028/MAX1030 operate from a single +5 V supply, while the MAX1227/MAX1229/MAX1231 and MAX1027/MAX1029/MAX1031 operate from a single +3.3 V supply. Low-power operation consumes 1.8 mA at the maximum conversion rate of 300 ksps. Automatic shutdown between conversions reduces operating current to 330 microamps at 10 ksps and no more than 5 microamps when the device is placed in complete shutdown.
