Productoverzicht
The MAX1149BEUP+ is a true differential, serial, 8-channel, 14bit SAR analogue to digital converter (ADC) in 20 pin TSSOP package. This low power ADC contains internal track/hold, voltage reference and clock. All analogue inputs are software configurable for unipolar/bipolar and single ended/differential operation. The 4-wire serial interface connects directly to SPI/QSPI/MICROWIRE devices without external logic. The serial strobe output (SSTRB) allows convenient connection to digital signal processors. The MAX1149 uses an internal clock or an external serial interface clock to perform SAR ADC conversions. The device includes an internal 2.5V reference and accepts an external reference from 1.5V to VDD. It provides hardware shutdown and two software power-down modes. The quick turn-on time allows power-down between all conversions. This technique reduces supply current to less than 120μA for quick turn-on. It is used in data acquisition, data logging & battery powered instruments.
- Supply voltage range from 2.7V to 3.6V
- Operating temperature range from -40°C to 85°C
- Shutdown supply current of 120μA (fast power-down mode) and 0.3μA (full power-down mode)
- 8-channel single ended or 4-channel differential inputs
- Throughput rate of 116.66Ksps (18 clocks/conversion) with external clock mode, fSCLK = 2.1MHz
- Low supply current of 1.1mA at 116Ksps sampling rate with external reference
- INL of ±0.7LSB and DNL of ±0.5LSB (no missing codes over temperature)
- Offset error of ±10LSB and offset temperature coefficient of 0.3ppm/°C
- Gain error of ±20LSB and gain temperature coefficient of ±0.8ppm/°C
- Small signal bandwidth (-3dB point) of 3MHz and full power bandwidth (SINAD <gt/> 68dB) of 2MHz
