Description

The MAX1303 multirange, low-power, 16-bit, successive-approximation, analog-to-digital converter (ADC) operates from a single +5V 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 the supply current to 1.3mA (typ). Full power-down mode reduces the power-supply current to 1µA (typ).

The MAX1303 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 (0V to +V_REF/2, -V_REF/2 to 0V, 0V to +V_REF, -V_REF to 0V, ±V_REF/4, ±V_REF/2, and ±V_REF), and three differential input ranges (±V_REF/2, ±V_REF, ±2 x V_REF).

An on-chip +4.096V reference offers a small convenient ADC solution. The MAX1303 also accepts an external reference voltage between 3.800V and 4.136V.

The MAX1303 is available in a 20-pin TSSOP package, and is specified for operation from -40°C to +85°C.
