ADS7835E/250G4

Analog To Digital Converters (ADC) Overview

The ADS7835E/250G4 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 500 kS/s and supports single-ended input signals via an SPI digital interface. The device functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of +/- 1 LSB, and integral nonlinearity of +/- 1 LSB. It features an internal reference and dissipates 17.5 mW of power. The component is housed in an 8-pin VSSOP package with dimensions of 3 mm x 3 mm x 0.97 mm height.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal voltage reference to simplify system design and reduce external component count.
• Supports serial communication through a standard SPI-compatible digital interface for efficient data transfer.
• Delivers high accuracy with specified differential and integral nonlinearity limits of +/- 1 LSB.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power consumption
• Battery-powered data acquisition devices
• Industrial process control monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the E variant meets the required operating temperature range of -40°C to +85°C. Ensure the VSSOP-8 package footprint matches the target PCB layout constraints. Validate that the 500 kS/s sampling rate aligns with the application bandwidth requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 12-bit ADC is needed with minimal external reference circuitry. Compare against the ADS7835EB/250G4 if different packaging or specific lot traceability is required. Consider the ADS7818E/250 if differential inputs are necessary instead of single-ended. Verify power supply stability within the 4.75 V to 5.25 V range to maintain specified linearity performance.
