The MAX1278ETC+ is a 1.8Msps, single-supply, low-power, true differential, 12bit ADC with internal reference in 12 pin TQFN package. This device features 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. This device easily interfaces with standard DSP synchronous serial interfaces. It has a bipolar analogue input with 4.096V internal reference. It features a partial power-down mode and a full power-down mode for use between conversions which lower the supply current to 2mA (typ) and 1μA (max), respectively. Also featured is a separate power-supply input which allows direct interfacing to +1.8V to VDD digital logic. The fast conversion speed, low-power dissipation, excellent AC performance and DC accuracy (±1.25 LSB INL) makes it ideal for industrial process control, motor control and base-station applications.
