Overview
The AD7478AARMZ is a high-speed, low-power successive-approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This 8-bit ADC is part of the AD7476A/AD7477A/AD7478A family and is designed for applications requiring high throughput rates with minimal power consumption.
The device operates from a single power supply ranging from 2.35 V to 5.25 V and features a throughput rate of up to 1 MSPS. It includes a low noise, wide bandwidth track-and-hold amplifier capable of handling input frequencies exceeding 13 MHz. The ADC is available in compact packages such as the 8-lead MSOP and 6-lead SC70, making it suitable for space-constrained designs.
