AD7450ARMZ Datasheet PDF - ADI

●The AD7450ARMZ is a 12-bit high-speed, low power, successive approximation Analog-to-digital Converter (ADC) that features a fully differential analog input. This part contains a low noise, wide bandwidth, differential track-and-hold amplifier that can handle input frequencies in excess of 1MHz with the -3dB point typically being 20MHz. The value of the reference voltage determines the common-mode voltage range of the part. With this truly differential input structure and variable reference input, the user can select a variety of input ranges and bias points. The conversion and data acquisition processes are controlled using CS and the serial clock, allowing the device to interface with microprocessors or DSPs. The input signals are sampled on the falling edge of CS and the conversion is also initiated at this point. The SAR architecture of this part ensures that there are no pipeline delays. It uses advanced design techniques to achieve low power dissipation at high throughput rates.
