ADS7835E

Analog To Digital Converters (ADC) Overview

The ADS7835E is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-ended input and operates on a 5V supply with an analog voltage range of 4.75 V to 5.25 V. The device supports a sampling rate of 500 kS/s and communicates via an SPI-compatible interface. Key performance metrics include a signal-to-noise ratio (SNR) of 72 dB, differential nonlinearity (DNL) of +/- 0.8 LSB, and integral nonlinearity (INL) of +/- 2 LSB. Power consumption is rated at 17.5 mW during operation and 30 mW maximum power dissipation. It includes an internal reference and is housed in an 8-pin VSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Texas Instruments, as Burr Brown was acquired by TI. Confirm the specific suffix 'E' indicates the commercial temperature range (-40°C to +85°C). Check RoHS compliance status through official datasheets or distributor documentation before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed, low-power ADC is required. Ensure the input signal is single-ended and within the 5V logic domain. Verify that the system can accommodate the VSSOP-8 package size and that the SPI interface timing matches the microcontroller capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7835 family of SAR ADCs. It is functionally similar to other devices in the series but distinguished by its specific packaging and temperature rating. The ADS7835E is designed for applications requiring moderate resolution and high throughput with minimal external components due to the integrated reference.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the Texas Instruments ADS7835 datasheet for pin-compatible alternatives within the same family. Verify electrical parameters such as SNR, DNL, and INL against the original requirements when considering substitutes from other manufacturers.
