DESCRIPTION
The LTC®1408 is a 14-bit, 600ksps ADC with six simultaneously sampled differential inputs. The device draws only 5mA from a single 3V supply, and comes in a tiny 32 pin (5mm × 5mm) QFN package. A SLEEP shutdown feature lowers power consumption to 6µW. The combination of low power and tiny package makes the LTC1408 suitable for portable applications.
