Texas Instruments ADS855x Analog-to-Digital Converters

Texas Instruments ADS855x Analog to Digital Converters include six low-power 16-, 14-, and 12-bit SAR ADCs with true bipolar inputs. Each channel of the TI ADS8556, ADS8557, and ADS8558 contains a sample-and-hold circuit that allows simultaneous high-speed multi-channel signal acquisition. These TI ADCs support data rates of up to 730kSPS in parallel interface mode or up to 500kSPS if the serial interface is used. The bus width of the parallel interface can be set to 8 or 16 bits. The ADS8556, ADS8557, and ADS8558 are specified over the full industrial temperature range of -40ºC to +125ºC and are available in an LQFP-64 package. This Texas Instruments ADC family is ideal for use in power quality measurement, protection relays, multi-axis motor control, programmable logic controllers, and industrial data acquisition.
