Texas Instruments ADS7863 Analog-to-Digital Converters
Texas Instruments ADS7863 Analog-to-Digital Converters (ADCs) have two independent 12-bit ADCs in one package allowing for throughput and simultaneous sampling. The Texas Instruments ADS7863 dual, 12-bit, 2MSPS ADC has four fully differential or six pseudo-differential input channels grouped into two pairs for high-speed, simultaneous signal acquisition. This architecture provides excellent common-mode rejection of 72dB at 100kHz, which is a critical performance characteristic in noisy environments. The evaluation module is available.Features
