ADS8482IRGZT

Analog To Digital Converters (ADC) Overview

The ADS8482IRGZT is an 18-bit, 1-MSPS analog-to-digital converter featuring a pseudo-bipolar, fully differential input architecture. It integrates a 4.096-V internal reference and utilizes a capacitor-based SAR structure with inherent sample-and-hold capabilities. The device supports flexible data interfaces, offering full 18-bit, 16-bit (two read cycles), or 8-bit (three read cycles) parallel bus options. Key electrical specifications include a maximum integral nonlinearity of ±2.5 LSBs, a typical signal-to-noise ratio of 99 dB, and a power dissipation of 225 mW at the maximum sampling rate.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZT' corresponds to the tape and reel packaging containing 250 units as defined in the ordering information. Confirm that the 'I' designation matches the required industrial temperature range of -40°C to 85°C for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high linearity and low noise are required for differential signals. The ADS8482IB variant offers tighter INL specifications (±2.5 LSB max) compared to the standard ADS8482I (±4 LSB max). Ensure the system design accommodates the separate analog (+VA) and digital (+VBD) supply requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the Texas Instruments High Speed SAR Converter family. It shares architectural similarities with the ADS8481 and ADS8382 series but is distinct in its pseudo-bipolar input configuration and integrated reference voltage, differentiating it from other members that may utilize unipolar inputs or external references.
