ADS7834E/250G4

Analog To Digital Converters (ADC) Overview

The ADS7834E/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 accepts differential input signals. 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, a maximum power dissipation of 20 mW, and typical power consumption of 11 mW. Linearity specifications are defined by a differential nonlinearity of ±0.8 LSB and integral nonlinearity of ±2 LSB. It utilizes an SPI interface and includes an internal reference.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 for lead-free compliance status against current manufacturer documentation. Confirm package type as VSSOP-8 and operating temperature range from -40°C to +85°C. Check datasheet for humidity sensitivity handling requirements during storage and assembly. Ensure SPI interface compatibility with the host microcontroller.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is required with differential inputs. Compare against ADS7818 if SPI interface is mandatory instead of standard serial protocols. Evaluate power constraints against the 11 mW typical consumption at 5V operation. Consider the internal reference feature if board space for external references is limited.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7834 series of high-speed, low-power ADCs. It shares architectural similarities with other SAR converters in the family but is distinct in its single-channel configuration and specific pinout. The E/250 designation indicates the commercial temperature grade and packaging variant.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7834E/250 is the direct equivalent without the RoHS suffix. ADS7818E/250 offers similar performance but uses a different serial interface protocol. Verify pin compatibility before substituting with other single-channel 12-bit SAR ADCs.
