The RS1430A is a 16-bit analog-to-digital (A/D) converter specified for a supply voltage range from 2.7V to 5.5V. It requires very little power, even when operating at the full data rate. At lower data rates, the high speed of the device enables it to spend most of its time in the power-down mode. For example, the average power dissipation is less than 162µW at a 10kHz data rate. The RS1430A offers excellent linearity and very low noise and distortion. It also features a synchronous serial (SPI/SSI-compatible) interface and a pseudo-differential input. The reference voltage can be set to any level within the range of 0.1V to VDD. Low power and small size make the RS1430A ideal for portable and battery-operated systems. It is also a perfect fit for remote data-acquisition modules, simultaneous multichannel systems, and isolated data acquisition. The RS1430A is available in an MSOP8 package.
