3 MSPS, 12-Bit ADC in 8-Lead MSOP and 6-Lead TSOT
The conversion process and data acquisition are controlled using CS and 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 also initiated at this point. There are no pipeline delays associated with the part.
The AD7276 uses advanced design techniques to achieve very low power dissipation at high throughput rates.
The reference for the part is taken internally from VDD. This allows the widest dynamic input range to the ADC; therefore, the analog input range for the part is 0 to VDD. The conversion rate is determined by the SCLK
- 3 MSPS ADCs in a 6-lead TSOT package
- AD7476/AD7477/AD7478 and AD7476A/AD7477A/ AD7478A pin-compatible
- High throughput with low power consumption
- Flexible power/serial clock speed management. This allows maximum power efficiency at low throughput rates
- Reference derived from the power supply
- No pipeline delay. The parts feature a standard successive approximation ADC with accurate control of the sampling instant via a CS input and once-off conversion control.
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-AD7276SDZ is a fully featured evaluation kit for the AD7276. This board operates in stand alone mode or in conjunction with the System Development Platform, EVAL-SDP-CB1Z . When operated with the System Development Platform, 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 System Development Platform . When operated in standalone mode the ADZS-BRKOUT-EX3 break out board is recommended for access to various control pins.
