ADS8342IPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS8342IPFBTG4 is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features four analog input channels with an integrated multiplexer and supports a maximum throughput of 250 kSPS. The device utilizes a bipolar ±5V power supply architecture, allowing for true bipolar input signal ranges up to ±2.5V when paired with a 2.5V reference. It incorporates a capacitor-based ADC with inherent sample-and-hold functionality and offers selectable 8-bit or 16-bit parallel data interfaces. Designed for industrial environments, it operates within a temperature range of –40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'G4' suffix indicates compliance with RoHS standards and lead-free manufacturing specifications as per Texas Instruments documentation. Confirm that the TQFP-48 package designation matches the required PCB footprint. Ensure the specific ordering number corresponds to the tape and reel transport media quantity if bulk procurement is intended.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-resolution bipolar signal processing at moderate speeds. The dual ±5V supply requirement must be accommodated in the system design. The parallel interface necessitates multiple microprocessor I/O lines; consider serial alternatives if pin count is constrained. Verify that the external clock frequency can reach up to 5MHz to achieve the maximum 250 kSPS throughput.

Analog To Digital Converters (ADC) Part Context

The ADS8342 belongs to Texas Instruments' family of precision SAR ADCs designed for multi-channel acquisition. It shares architectural similarities with other devices in the series but is distinguished by its specific bipolar supply requirements and parallel output configuration. This model serves as a bridge between low-speed precision converters and high-speed single-channel solutions.
