ADS8405IBPFBT

Analog To Digital Converters (ADC) Overview

The ADS8405IBPFBT is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a single pseudo-differential or single-ended input channel and supports sampling rates up to 1.25 MSPS. The device utilizes a parallel interface for data output and features an internal oscillator. Power requirements include 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 of 86 dB, differential nonlinearity of -1/1.5 LSB, and integral nonlinearity of +/- 2 LSB. It is housed in a TQFP-48 package and functions within a temperature range of -40°C to +85°C.
