ADC Hex SAR 630ksps 16-bit Parallel/Serial 64-Pin LQFP Bulk, ADS8555SPM, Texas Instruments

The ADS8555 contains six low-power, 16-bit, successive approximation register (SAR)-based analog-to-digital converters (ADCs) with true bipolar inputs. Each channel contains a sample-and-hold circuit that allows simultaneous high-speed multi-channel signal acquisition. The ADS8555 supports data rates of up to 630kSPS in parallel interface mode or up to 450kSPS if the serial interface is used. The bus width of the parallel interface can be set to eight or 16 bits. In serial mode, up to three output channels can be activated. The ADS8555 is specified over the extended industrial temperature range of –40°C to +125°C and is available in an LQFP-64 package.
