Description
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 (0 to +VREF/2, -VREF/2 to 0, 0 to +VREF, -VREF to 0, ±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.
