ADS7834EB/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS7834EB/2K5G4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential input channel and operates with an SPI-compatible serial interface. The device supports sampling rates up to 500 kS/s while maintaining low power consumption, typically 11 mW at full speed. It requires dual supply voltages for analog and digital sections, both ranging from 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of ±0.8 LSB, and integral nonlinearity of ±2 LSB. The component is housed in an 8-pin VSSOP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'B' against official Texas Instruments documentation to confirm pinout or electrical variations compared to the standard 'E' variant. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the reel packaging matches the required quantity specifications for the production line.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 500 kS/s throughput are required in a compact surface-mount package. It is suitable for designs needing a built-in reference source to reduce board space. Compare power dissipation requirements against the 11 mW typical value to ensure thermal management meets system constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7834 family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with the ADS7816 and ADS7835 but offers specific performance trade-offs regarding speed and power. The '/2K5G4' suffix indicates a tape-and-reel packaging format containing 2500 units, designed for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed direct substitutes for the ADS7834EB/2K5G4 were not identified in the provided documentation. Designers should consult the manufacturer's current selection guide for potential cross-reference options that match the 12-bit SAR architecture and VSSOP-8 footprint.
