AD7441BRMZ Datasheet PDF - ADI

●The AD7441BRMZ is a 10-bit high speed low power single-supply successive approximation Analog-to-digital Converter (ADC) that features a pseudo differential analog input. This operates from a single 2.7 to 5.25V power supply and achieves very low power dissipation at high throughput rates of up to 1MSPS. It contains a low noise, wide bandwidth, differential track-and-hold amplifier that handles input frequencies up to 3.5MHz. The reference voltage for these devices is applied externally to the VREF pin and can range from 100mV to VDD depending on the power supply and what suits the application. The conversion process and data acquisition 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 when the conversion is initiated. The SAR architecture of these parts ensures that there are no pipeline delays.
