MAX1302BEUG+

The MAX1302BEUG+ is an 8-channel, ±VREF multirange inputs, serial 16bit analogue to digital converter in 24 pin TSSOP package. The successive approximation ADC operates from a single +5V supply and achieves throughput rates up to 115Ksps. A separate digital supply allows digital interfacing with a 2.7V to 5.25V system using SPI/QSPI/MICROWIRE compatible serial interface. Partial power-down mode reduces the supply current to 1.3mA (typ). Full power-down mode reduces the power supply current to 1μA. The MAX1302 provides eight single-ended or four 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). An on-chip +4.096V reference offers a small convenient ADC solution. The MAX1302 also accepts an external reference voltage between 3.800V and 4.136V.

• 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
• Integral nonlinearity is ±1LSB
