MAX1033

8- and 4-Channel, ±3 x VREF Multirange Inputs, Serial 14-Bit ADCs

Low-Power, Multichannel ADCs with ±3 x VREF Input Range


Please check latest availability status for a specific part variant.

Description

The MAX1032/MAX1033 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 MAX1032 provides eight (single-ended) or four (true differential) analog input channels. The MAX1033 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 × VREF)/2, (-3 × VREF)/2 to 0, 0 to 3 × VREF, -3 × VREF to 0, (±3 × VREF)/4, (±3 × VREF)/2, ±3 × VREF and three differential input ranges (±3 × VREF)/2, ±3 × VREF, ±6 × VREF.

An on-chip +4.096V reference offers a small convenient ADC solution. The MAX1032/MAX1033 also accept an external reference voltage between 3.800V and 4.136V.

The MAX1032 is available in a 24-pin TSSOP package and the MAX1033 is available in a 20-pin TSSOP package. Each device is specified for operation from -40°C to +85°C.
