The AD7441/AD7451* are, respectively, 10-/12-bit high speed, low power, single-supply, successive approximation (SAR), analog-to-digital converters (ADCs) that feature a pseudo differential analog input. These parts operate from a single 2.7 V to 5.25 V power supply and achieve very low power dissipation at high throughput rates of up to 1 MSPS.
The AD7441/AD7451 contain a low noise, wide bandwidth, differential track-and-hold (T/H) amplifier that handles input frequencies up to 3.5 MHz. The reference voltage for these devices is applied externally to the VREF pin and can range from 100 mV to VDD, depending on the power supply and what suits the application.
The conversion process and data acquisition are controlled using overbar: CS and the serial clock, allowing the device to interface with microprocessors or DSPs. The input signals are sampled on the falling edge of overbar: CS when the conversion is initiated. The SAR architecture of these parts ensures that there are no pipeline delays.
