The MAX1300/MAX1301 multirange, low-power, 16-bit, successive-approximation, analog-to-digital converters (ADCs) operate from a single +5V supply and achieve
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 the supply current to 1.3mA (typ). Full power-down mode reduces the power-supply current to 1µA (typ).
The MAX1300 provides eight (single-ended) or four (true differential) analog input channels. The MAX1301 provides four (single-ended) or two (true differential) analog input channels. Each analog input channel is independently software programmable for seven single-ended input ranges (0 to +3VREF/2, -3VREF/2 to 0, 0 to +3VREF, -3VREF to 0, ±3VREF/4, ±3VREF/2, and ±3VREF), and three differential input ranges (±3VREF/2, ±3VREF, ±6VREF).
An on-chip +4.096V reference offers a small convenient ADC solution. The MAX1300/MAX1301 also accept an external reference voltage between 3.800V and 4.136V. The MAX1300 is available in a 24-pin TSSOP package and the MAX1301 is available in a 20-pin TSSOP package. Each device is specified for operation from -40°C to +85°C.
