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 (3 × V_REF)/2, (-3 × V_REF)/2 to 0, 0 to 3 × V_REF, -3 × V_REF to 0, (±3 × V_REF)/4, (±3 × V_REF)/2, ±3 × V_REF] and three differential input ranges [(±3 × V_REF)/2, ±3 × V_REF, ±6 × V_REF].

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.
