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 × 3mm DFN. The low power consumption and small size make the LTC2302/LTC2306...
