1MSPS, 12-Bit ADC in 6 Lead SOT-23
The conversion process and data acquisition are controlled using CS the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and the conversion is initiated at this point. There are no pipeline delays associated with these parts.
The AD7476/AD7477/AD7478 use advanced design techniques to achieve very low power dissipation at high throughput rates. The reference for the parts is taken internally from VDD. This allows the widest dynamic input range to the ADC. Thus, the analog input range for the parts are 0 V to VDD. The conversion rate is determined by the SCLK.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The EVAL-AD7476ACBZ is a fully featured evaluation kit for the AD7476A. This board operates in stand alone mode or in conjunction with the Evaluation Controller board . When operated with the Evaluation Controller board, software is provided enabling the user to perform detailed analysis of the ADC's performance. This software includes the technical note describing the operation and set up of the evaluation board in standalone operation or when operated with the Evaluation Controller board.
