Description

The MAX1277/MAX1279 are low-power, high-speed, serial-output, 12-bit, analog-to-digital converters (ADCs) with an internal reference that operates at up to 1.5Msps. 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 MAX1277/MAX1279 operate from a single +2.7V to +3.6V supply voltage. The MAX1277/MAX1279 include a 2.048V internal reference. The MAX1277 has a unipolar analog input, while the MAX1279 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 2mA (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 MAX1277/MAX1279 ideal for industrial process control, motor control, and base-station applications. The MAX1277/MAX1279 come in a 12-pin TQFN package, and are available in the extended (-40°C to +85°C) temperature range.
