ADS805E

Analog To Digital Converters (ADC) Overview

The ADS805E is a high-performance, single-channel 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a pipeline architecture with an integrated sample-and-hold amplifier to achieve a sampling rate of 20 MSPS. The device operates on a single 5V supply for both analog and digital domains. It supports differential or single-ended input configurations and features a parallel data interface. The component is housed in a 28-lead SSOP package and is rated for operation within a temperature range of -40°C to +85°C.
