AD7484BSTZ Datasheet PDF - ADI

●The AD7484BSTZ is a 14-bit high speed low power successive approximation Analog-to-digital Converter (ADC) features a parallel interface with throughput rates up to 3MSPS. The part contains a low noise, wide bandwidth track-and-hold that can handle input frequencies in excess of 40MHz. The conversion process is a proprietary algorithmic successive approximation technique that results in no pipeline delays. The input signal is sampled and a conversion is initiated on the falling edge of the CONVST signal. The conversion process is controlled by an internally trimmed oscillator. Interfacing is via standard parallel signal lines, making the part directly compatible with microcontrollers and DSPs. It provides excellent AC and DC performance specifications. Factory trimming ensures high DC accuracy, resulting in very low INL, offset and gain errors. The part uses advanced design techniques to achieve very low power dissipation at high throughput rates.
