The MAX1274/MAX1275 low-power, high-speed, serial-output, 12-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 single-ended 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 MAX1274/MAX1275 operate from a single +4.75V to +5.25V supply voltage and require an external reference. The MAX1274 has a unipolar analog input, while the MAX1275 has a bipolar 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 1mA (typ) and 1µA (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 (±1 LSB INL) make the MAX1274/MAX1275 ideal for industrial process control, motor control, and base-station applications.
The MAX1274/MAX1275 come in a 12-pin TQFN package, and are available in the extended (-40°C to +85°C) temperature range.
