AD7680:  100 kSPS, 16-Bit PulSAR® ADC in 6 Lead SOT-23

产品详情

The AD7680 is a 16-bit, fast, low power, successive-approximation ADC. The part operates from a single 2.5 V to 5.25 V power supply and features throughput rates up to 100 kSPS. The part contains a low-noise, wide bandwidth track/hold amplifier, which can handle input frequencies in excess of 100 kHz.

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 pipelined delays associated with the part.

The AD7860 uses advanced design techniques to achieve very low-power dissipation at fast throughput rates. The reference for the part is taken internally from VDD. This allows the widest dynamic input range to the ADC. Thus the analog input range for the part is 0 to VDD. The conversion rate is determined by the SCLK frequency.
