ADS8406IBPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS8406IBPFBTG4 is a 16-bit, 2-MSPS analog-to-digital converter (ADC) from Texas Instruments. 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. It utilizes a parallel interface and is housed in a TQFP-48 package. Power consumption is specified at 155 mW, with operation supported across a temperature range of -40°C to +85°C.
