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 +6V, -6V to 0, 0 to +12V, -12V to 0, ±3V, ±6V, and ±12V), and three differential input ranges (±6V, ±12V, ±24V).
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.
