MAX11626

The MAX11626-MAX11629 are available in 16-pin QSOP packages. The MAX11632/MAX11633 are available in 24-pin QSOP packages. All eight devices are specified over the extended -40°C to +85°C temperature range. The MAX11632/ MAX11633 have 16 input channels; the MAX11628/ MAX11629 have 8 input channels; and the MAX11626/ MAX11627 have 4 input channels. These eight devices operate from either a +3V supply or a +5V supply, and contain a 10MHz SPITM-/QSPITM-/MICROWIRETM-compatible serial port. The MAX11626-MAX11629/MAX11632/MAX11633 are serial 12-bit analog-to-digital converters (ADCs)with an internal reference. These devices feature on-chip FIFO, scan mode, internal clock mode, internal averaging, and AutoShutdownTM. The maximum sampling rate is 300ksps using an external clock.

The features of MAX11626 can be summarized as (1)analog multiplexer with track/hold 16 channels (MAX11632 / MAX11633) / 8 channels (MAX11628 / MAX11629) / 4 channels (MAX11626 / MAX11627); (2)single supply 2.7V to 3.6V (MAX11627 / MAX11629 / MAX11633) / 4.75V to 5.25V (MAX11626 / MAX11628 / MAX11632); (3)internal reference 2.5V (MAX11627 / MAX11629 / MAX11633) / 4.096V (MAX11626 / MAX11628 / MAX11632); (4)external reference: 1V to VDD; (5)16-entry first-in/first-out (FIFO); (6)scan mode, internal averaging, and internal clock; (7)accuracy: ±1 LSB INL, ±1 LSB DNL, no missing codes over temperature; (8)10MHz 3-Wire SPI-/QSPI-/MICROWIRE-compatible interface; (9)small packages 16-pin QSOP (MAX11626-MAX11629)/ 24-pin QSOP (MAX11632/MAX11633).

The absolute maximum ratings of MAX11626 are (1)VDD to GND: -0.3V to +6V; (2)CS, SCLK, DIN, EOC, DOUT to GND: -0.3V to (VDD + 0.3V); (3)AIN0AIN13, AIN_, CNVST/AIN_, REF to GND: -0.3V to (VDD + 0.3V); (4)maximum current into any pin: 50mA; (5)continuous power dissipation (TA = +70°C)16-pin QSOP (derate 8.3mW/°C above +70°C): 667mW / 24-pin QSOP (derate 9.5mW/°C above +70°C): 762mW; (6)operating temperature range: -40°C to +85°C; (7)storage temperature range: -60°C to +150°C; (8)junction temperature: +150°C; (9)lead temperature (soldering, 10s): +300°C; (10)soldering temperature (reflow): +260°C.
