The LTC2302/LTC2306 are low noise, 500ksps, 1-/2-channel, 12-bit ADCs with an SPI/MICROWIRE compatible serial interface. These ADCs include a fully differential sample-and-hold circuit to reduce common mode noise. The internal conversion clock allows the external serial output data clock (SCK) to operate at any frequency up to 40MHz.

The LTC2302/LTC2306 operate from a single 5V supply and draw just 2.8mA at a sample rate of 500ksps. The auto-shutdown feature reduces the supply current to 14μA at a sample rate of 1ksps.

The LTC2302/LTC2306 are packaged in a tiny 10-pin 3mm x 3mm DFN. The low power consumption and small size make the LTC2302/LTC2306 ideal for battery-operated and portable applications, while the 4-wire SPI compatible serial interface makes these ADCs a good match for isolated or remote data acquisition systems.

Applications

  • High Speed Data Acquisition
  • Industrial Process Control
  • Motor Control
  • Accelerometer Measurements
  • Battery-Operated Instruments
  • Isolated and/or Remote Data Acquisition
