The MAX1303 ADC has a resolution of 16 bits. - What is the maximum throughput rate of the MAX1303?
The maximum throughput rate is up to 115ksps. - What are the supply voltage requirements for the MAX1303?
The MAX1303 operates from a single +5V supply for analog operations and supports digital interfacing with systems operating between 2.7V and 5.25V. - How many input channels does the MAX1303 have?
The MAX1303 has four single-ended or two differential analog input channels. - What are the input ranges for the MAX1303?
The input ranges include single-ended and differential options: single-ended (0V to +VREF/2, -VREF/2 to 0V, 0V to +VREF, -VREF to 0V, ±VREF/4, ±VREF/2, and ±VREF); differential (±VREF/2, ±VREF, and ±2 x VREF). - Can the MAX1303 use an external reference voltage?
Yes, the MAX1303 can use an external reference voltage between 3.800V and 4.136V, or it can use the internal +4.096V reference. - What is the operating temperature range of the MAX1303?
