ADS8406IBPFBT

Analog To Digital Converters (ADC) Overview

The ADS8406IBPFBT is a 16-bit, 1.25 MSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture with an internal 4.096 V reference. The device operates on a single +5V analog supply and supports pseudo-differential or single-ended inputs. Key electrical parameters include a maximum integral nonlinearity (INL) of ±2 LSB and differential nonlinearity (DNL) of -1/+1.25 LSB. It achieves a signal-to-noise ratio (SNR) of 90 dB at a 100 kHz input frequency. The component is housed in a 48-lead TQFP package and functions within a temperature range of -40°C to +85°C.
