Аналого-цифровые преобразователи (АЦП) MAX11614EEE+

АЦП , низкой мощности, 12 бит, 94.4 Квыборок/с, Дифференциальный, Несимметричный, I2C, Однополярный

The MAX11614EEE+ is a low power, 8-channel, 12bit analogue to digital converter (ADC) in 16 pin QSOP package. This device has internal track/hold (T/H), voltage reference, clock and an I2C compatible 2-wire serial interface (400KHz fast mode, 1.7MHz high speed mode). It requires only 670µA supply current at maximum sampling rate of 94.4Ksps. Supply current falls below 230µA for sampling rate under 46Ksps. AutoShutdown feature power down the device between conversions by reducing supply current to less than 1µA at low throughput rates. The fully differential analogue inputs are software configurable for unipolar or bipolar and single ended or differential operation. The full scale analogue input range is determined by internal reference or by an externally applied reference voltage ranging from 1V to VDD. The MAX11614 is used in battery powered test equipments, solar powered remote systems, received signal strength indicators and system supervision.

• Supply voltage range from 4.5V to 5.5V
• Operating temperature range from -40°C to 85°C
• Internal reference of 4.096V and internal clock
• 8-channel single ended or 4-channel fully differential
• Internal FIFO with channel scan mode
• INL of ±1LSB and DNL of ±1LSB (no missing codes over temperature)
• Offset error of ±4LSB and gain error of ±4LSB
• Full power bandwidth of 3MHz (SINAD > 68dB) and full linear bandwidth of 5MHz (-3dB point)
