The LTC®2351-12 is a 12-bit, 1.5Msps ADC with six simultaneously sampled differential inputs. The device draws only 5.5mA from a single 3V supply, and comes in a tiny 32-pin (5mm × 5mm) QFN package. A Sleep shutdown mode further reduces power consumption to 12μW. The combination of low power and tiny package makes the LTC2351-12 suitable for portable applications. The LTC2351-12 contains six separate differential inputs that are sampled simultaneously on the rising edge of the CONV signal. These six sampled inputs are then converted at a rate...
