ADS8405IPFBT

Analog To Digital Converters (ADC) Overview

The ADS8405IPFBT is a single-channel, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It utilizes a successive approximation register (SAR) architecture to achieve a sampling rate of 1.25 MSPS. The device supports pseudo-differential or single-ended input configurations and features a parallel interface for data transfer. It operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 2.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 86 dB, differential nonlinearity (DNL) of -1/1.5 LSB, and integral nonlinearity (INL) of +/- 2 LSB. The component is housed in a TQFP-48 package and functions within a temperature range of -40°C to +85°C.
