The AD7440 / AD7450A are 10-bit and 12-bit high speed, low power, successive approximation (SAR) analog-to-digital converters with a fully differential analog input. These parts operate from a single 3 V or 5 V power supply and use advanced design techniques to achieve very low powerdissipation at throughput rates up to 1 MSPS. The SAR architecture of these parts ensures that there are no pipeline delays.The parts contain a low noise, wide bandwidth, differential track-and-hold amplifier (T/H) that can handle input frequencies up to 3.5 MHz. The reference voltage is applied externally to the VREF pin and can be varied from 100 mV to 3.5 V depending on the power supply and what suits theapplication. 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 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; the conversion is also initiated at this point. The SAR architecture of these parts ensures that there are no pipeline delays. The AD7440 and the AD7450A use advanced design techniques to achieve very low power dissipation at high throughput rates.PRODUCT HIGHLIGHTS Operation with either 3 V or 5 V power supplies. High throughput with low power consumption. With a 3 V supply, the AD7440 / AD7450A offer 4 mW max power consumption for 1 MSPS throughput. Fully differential analog input. Flexible power/serial clock speed management. The conversion rate is determined by the serial clock, allowing the power to be reduced as the conversion time is reduced through the serial clock speed increase. These parts also feature a shutdown mode to maximize power efficiency at lower throughput rates. Variable voltage reference input. No pipeline delay. Accurate control of the sampling instant via a CS input and once-off conversion control. ENOB > eight bits typically with 100 mV reference.
