ADS8405IPFBR

Analog To Digital Converters (ADC) Overview

The ADS8405IPFBR is a 16-bit, 1.25 MSPS analog-to-digital converter (ADC) from Texas Instruments, housed in a 48-pin TQFP package. It features a successive approximation register (SAR) architecture with a single pseudo-differential or single-ended input channel. The device operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply 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. Power consumption is specified at 155 mW typical, with a maximum power dissipation of 170 mW. It supports both external and internal reference configurations.
