AD7821KN Description

Short technical summary and product information.

The AD7821KN from Analog Devices is an 8-bit sampling analog-to-digital converter designed for high-speed applications. It boasts a maximum conversion time of 660 ns, significantly faster than previous models, and includes a built-in track-and-hold function capable of handling signals up to 100 kHz.

 

This ADC utilizes a half-flash conversion technique and is fabricated using LC2MOS technology, enabling efficient operation with low power dissipation of 50 mW. It supports both unipolar and bipolar input ranges and features ratiometric reference inputs, eliminating the need for an external clock signal. The device is designed for extended temperature range operation.

 

The AD7821KN is available in multiple package options, including skinny 20-lead DIP, SOIC, and 20-terminal surface-mount configurations, offering flexibility for various board designs. Its microprocessor-compatible control signals and three-state data outputs facilitate easy integration into high-speed data buses.
