Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe MAX1334/MAX1335 2-channel, serial-output, 10-bit, analog-to-digital converters (ADCs) feature two true-differential analog inputs and offer outstanding noise immunity and dynamic performance. Both devices easily interface with SPI™/QSPI™/MICROWIRE™ and standard digital signal processors (DSPs).
The MAX1334 operates from a single +4.75V to +5.25V supply with sampling rates up to 4.5Msps. The MAX1335 operates from a single +2.7V to +3.6V supply with sampling rates up to 4Msps. These devices featurea partial power-down mode and a full power-down mode that reduce the supply current to 3.3mA and 0.2A, respectively. Also featured is a separate powersupply input (DVDD) that allows direct interfacing to +2.7V to +3.6V digital logic. The fast conversion speed, low power dissipation, excellent AC performance, and DC accuracy (±0.4 LSB INL) make the MAX1334/ MAX1335 ideal for industrial process control, motor control, and base-station applications.
The MAX1334/MAX1335 are available in a space-saving (3mm x 3mm), 16-pin, TQFN package and operate over the extended (-40°C to +85°C) temperature range.
