Поставка оригинальных MAX1231BCEG+T, Сбор данных - Аналого-цифровые преобразователи (АЦП), от Maxim Integrated

The MAX1227/MAX1229/MAX1231 are serial 12-bit analog-to-digital converters (ADCs) with an internal reference and an internal temperature sensor.
These devices feature an on-chip FIFO, scan mode, internal clock mode, internal averaging, and AutoShutdown™.
The maximum sampling rate is 300ksps using an external clock.
The MAX1231 has 16 input channels, the MAX1229 has 12 input channels, and the MAX1227 has 8 input channels. All input channels are configurable for single-ended or differential inputs in unipolar or bipolar mode. All three devices operate from a +3V supply and contain a 10MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial port.
The MAX1231 is available in 28-pin 5mm x 5mm TQFN with exposed pad and 24-pin QSOP packages.
The MAX1227/MAX1229 are only available in QSOP packages. All three devices are specified over the extended -40°C to +85°C temperature range.
