AD7276YUJZ-500RL7

AD7276 is a 12bit, high speed, low power, successive approximation analogue-to-digital converter (ADC). It operates from a single 2.35V to 3.6V power supply and feature throughput rates of upto 3MSPS. The parts contain a low noise, wide bandwidth track and-hold amplifier that can handle input frequencies in excess of 55MHz. 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 initiated at this point. There are no pipeline delays associated with the part. It 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 analogue input range for the part is 0 to VDD. The conversion rate is determined by the SCLK.
