Product Details
The MAX1034/MAX1035 multirange, low-power, 14-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 MAX1034 provides eight (single-ended) or four (true differential) analog input channels. The MAX1035 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 +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 MAX1034/MAX1035 also accept an external reference voltage between 3.800V and 4.136V.
The MAX1034 is available in a 24-pin TSSOP package and the MAX1035 is available in a 20-pin TSSOP package. Each device is specified for operation from -40°C to +85°C.
