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.
Description
The MAX1076/MAX1078 low-power, high-speed, serialoutput, 10-bit, analog-to-digital converters (ADCs) operate at up to 1.8Msps. These devices feature true-differential inputs, offering better noise immunity, distortion improvements, and a wider dynamic range over singleended inputs. A standard SPI/QSPI/MICROWIRE interface provides the clock necessary for conversion. These devices easily interface with standard digital signal processor (DSP) synchronous serial interfaces.
The MAX1076/MAX1078 operate from a single +4.7to +5.25 supply voltage. They include a 4.09 Vinternal reference. The MAX1076 has a unipolar analog input. These devices feature a partial power-down mode and a full power-down mode for use between conversions,which lower the supply current to 2mA (typ) and 1A (max), respectively. Also featured is a separate power-supply input (VL), which allows direct interfacing to +1.8V to VDD digital logic. The fast conversion speed,low-power dissipation, excellent AC performance, and DC accuracy (±0.5 LSB INL) make the MAX1076/MAX1078 ideal for industrial process control, motor control, and base-station applications.
MAX1076/MAX1078 come in a 12-pin TQFN package, and are available in the commercial (0°C to +70°C) and extended (-40°C to +85°C) temperature ranges.
