AD7821KR Description

Short technical summary and product information.

The AD7821KR from Analog Devices Inc. is a high-speed, 8-bit sampling analog-to-digital converter (ADC) designed for improved performance. It boasts a fast conversion time of 660 ns maximum and includes a 100 kHz track-and-hold function, capable of digitizing full-scale signals up to this frequency.

This ADC operates with a 1 MHz sample rate and supports both unipolar and bipolar input ranges. It utilizes a half-flash conversion technique, eliminating the need for an external clock signal. The device is designed with standard microprocessor control signals and latched, three-state data outputs for interfacing with high-speed data buses.

The AD7821KR is fabricated using LC2MOS technology, combining precision bipolar circuits with low-power CMOS logic, resulting in a low power dissipation of 50 mW. It is available in a 20-SOIC surface-mount package and operates over an extended temperature range of -40°C to 85°C.
