Overview
The AD7451ARMZ is a 12-bit, high-speed, low-power, single-supply, successive approximation (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed to operate from a single 2.7 V to 5.25 V power supply, making it suitable for a wide range of applications requiring high throughput and low power consumption. The AD7451 features a pseudo differential analog input and a low noise, wide bandwidth, differential track-and-hold (T/H) amplifier, enabling it to handle input frequencies up to 3.5 MHz.
