ADS8342IPFBT

Analog To Digital Converters (ADC) Overview

The ADS8342IPFBT is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features four analog input channels with an internal multiplexer and operates at sampling rates up to 250kSPS. The device utilizes a ±5V power supply architecture for analog and digital sections, with a separate I/O buffer supply (BVDD) supporting 2.7V to 5.5V logic levels. It provides a selectable 8-bit or 16-bit parallel interface with 3-state outputs. Key electrical specifications include a maximum integral nonlinearity error of ±4 LSBs, no missing codes guaranteed at 16 bits, and a typical signal-to-noise ratio of 86 dB. The component is housed in a TQFP-48 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the transport media and quantity. The IPFBT designation indicates tape and reel packaging containing 250 units. Confirm that the required performance grade matches the IB variant specifications, which ensure 16-bit no missing codes and tighter linearity errors compared to the standard I grade.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed 16-bit conversion is required with multiple input channels. Ensure the system design supports dual ±5V analog/digital supplies plus a separate BVDD supply for the I/O buffer. Verify that the host microprocessor can accommodate the parallel data bus width and timing requirements for the CONV, CS, and RD signals. Consider the thermal dissipation characteristics if operating near the upper temperature limits.

Analog To Digital Converters (ADC) Part Context

The ADS8342 belongs to the ADS834x family of high-speed, low-power ADCs from Texas Instruments. This series includes variants such as the ADS8341, ADS8343, ADS8344, and ADS8345, which differ primarily in channel count and pin compatibility. The ADS8342 specifically offers four channels in a TQFP-48 package, distinguishing it from the eight-channel ADS8344/ADS8345 and the two/four-channel ADS8341/ADS8343.
