MAX1303BEUP+

The MAX1303BEUP+ is a 4-channel, ±VREF multirange inputs, serial 16bit ADC in 20 pin TSSOP package. This successive-approximation ADC operates from a single supply and achieves throughput rates up to 115Ksps. A separate digital supply allows digital interfacing with 2.7V to 5.25V systems using the SPI/QSPI /MICROWIRE -compatible serial interface. Partial power-down mode reduces supply current to 1.3mA (typ) and full power-down mode reduces power-supply current to 1µA (typ). It provides four (single-ended) or two (true differential) analogue input channels. Each analogue input channel is independently software programmable for seven single-ended input ranges (0V to +VREF/2, -VREF/2 to 0V, 0V to +VREF, -VREF to 0V, ±VREF/4, ±VREF/2 and ±VREF) and three differential input ranges (±VREF/2, ±VREF, ±2 x VREF). Device is used in avionics and data-acquisition systems.

• Supply voltage range is 4.75V to 5.25V
• Operating temperature range from -40°C to 85°C
• Software programmable input range for each channel
• ±6V overvoltage tolerant inputs
• Maximum INL of ±4LSB, DNL of +2LSB at no missing codes
• Maximum small-signal bandwidth of 1.5MHz at all input ranges, VIN = 100mVp-p
