The AD7866 is a dual 12-bit high-speed, low power, successive-approximation ADC. The part operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 1 MSPS. The device contains two ADCs, each preceded by a low-noise, wide bandwidth track/hold amplifier, which can handle input frequencies in excess of 10 MHz.
The conversion process and data acquisition are controlled using standard control inputs allowing easy interfacing to microprocessors or DSPs. The input signal is sampled on the falling edge of CS and conversion is also initiated at this point. The conversion time is determined by the SCLK frequency. There are no pipelined delays with the part.
The AD7866 uses advanced design techniques to achieve very low power dissipation at high throughput rates. With 3 V supplies and 1 MSPS throughput rate, the part consumes a maximum of 3.8 mA. With 5 V supplies and 1 MSPS, the current consumption is a maximum of 4.8 mA. The part also offers flexible power/throughput rate management when operating in sleep mode.
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.
