Multichannel, True-Differential, Serial, 14-Bit ADCs
General Description
The MAX1146–MAX1149 low-power, 14-bit, multichannel, analog-to-digital converters (ADCs) feature an internal track/hold (T/H),
voltage reference, and clock. The MAX1146/MAX1148 operate from a single +4.75V to +5.25V supply, and the MAX1147/MAX1149 operate from a single +2.7V to +3.6V supply. All analog inputs are software configurable for unipolar/bipolar and single-ended/differential operation.
The 4-wire serial interface connects directly to SPI™/QSPI™/MICROWIRE™ devices without external logic. The serial strobe output (SSTRB) allows convenient connection to digital signal processors. The MAX1146–MAX1149 use an internal clock or an external serial-interface clock to perform successive-approximation analog-to-digital conversions.
The MAX1146/MAX1148 include an internal +4.096V reference, while the MAX1147/MAX1149 include an internal +2.500...
