6-Channel SAR ADCs for Industrial Monitoring and Portable Instruments:The 14-bit LTC2351-14 is a 1.5Msps, low power SAR ADC with six simultaneously sampled differential input channels. It operates from a single 3V supply and features six independent sample-and-hold amplifi ers and a single ADC. The single ADC with multiple S/HAs enables excellent range match (1mV) between channels and channel-tochannel skew (200ps). The versatile LTC2351-14 is ideally suited for industrial monitoring applications such as 3-phase power line monitoring to ensure line voltage compliance, portable power line instrumentation, power factor correction, motor control, and data acquisition. These applications may be battery powered, and it is here that the LTC2351-14’s low power and small size are desirable. Power consumption is a mere 16.5mW, which extends battery life. The 3-wire serial interface means fewer pins than parallel output devices, allowing the LTC2351-14 to fi t in a 32-pin,5mm × 5mm QFN package.
