Top Stories TI's New 16-Bit Converter with Six ADC's In One Package Device Surpasses Competition with 50% More Channels and 4x Throughput for Motor Control, Optical Networking and Power Monitoring Texas Instruments has introduced the industry?s first 16-bit analog-to-digital converter (ADC) to feature six independent ADCs in one package. This high-performance device from the company?s Burr-Brown product line allows high signal throughput and simultaneous sampling in motor control, multi-axis positioning, power monitoring and optical networking applications. The ADS8364 provides 250kSPS simultaneous sampling and conversion of all six input channels with low power consumption (69mW/channel) and a 2.7V to 5.5V digital interface voltage -- all at a low cost per channel. The device includes six high-speed sample-and-holds, six high-speed ADCs, a reference and three reference buffers, and with an on-board FIFO, provides a flexible and easy-to-use interface to DSPs and MCUs. "The ADS8364 surpasses the nearest competition with 50 percent higher channel count and 4x higher throughput rate. Alternatively, building a similar system with discrete components would require much larger board space, higher power consumption and a more expensive overall component count," said Miroslav Oljaca, strategic marketing engineer for TI's data acquisition products. "This is the latest addition to TI's simultaneous sampling converter portfolio that addresses motor control, industrial, power and optical monitoring and control applications." The ADS8364 is specified to have 14-bit no missing codes with a 5V supply, and also offers +/-3 LSB INL, +/-1.5 LSB DNL and -92dB distortion at 100kHz. Inputs to the sample-and-hold amplifiers are fully differential and maintained differential to the input of the ADC. This provides excellent common-mode rejection of 80dB at 50kHz, which is important in high-noise environments such as motor control and power conversion. The ADS8364 offers a flexible high-speed parallel interface with a direct address or cycle mode and an on-board FIFO. The output data for each channel is available as an 8-bit or 16-bit word.
