The AD7475/AD7495 is a 1 MSPS, 12-bit ADC with high throughput and low power consumption. It operates from a single supply voltage and features the VDRIVE function, allowing it to connect to 3V or 5V processor systems. It also has flexible power/serial clock speed management, allowing the conversion time to be reduced through an increase in the serial clock speed, and maximizing power efficiency at lower throughput rates.
The AD7475/AD7495 are 12-bit high-speed, low-power, successive-approximation ADCs designed for applications requiring fast throughput and single-supply operation. They operate from a supply voltage of 2.7 V to 5.25 V and feature a track/hold amplifier capable of handling input frequencies in excess of 1 MHz.
The devices utilize an advanced design to achieve very low power dissipation, consuming as little as 4.5 mW at 1 MSPS with 3 V supplies for the AD7475. The conversion process is controlled via a Chip Select (CS) and serial clock input, allowing direct interfacing with microprocessors or DSPs without pipeline delays.
