ADS7853IRTER

Analog To Digital Converters (ADC) Overview

The ADS7853IRTER is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 1.65 V to 5.5 V. The device supports a sampling rate of 1 MSPS per channel and features an SPI-compatible serial interface. Key performance metrics include a signal-to-noise ratio (SNR) of 82 dB and a signal-to-noise and distortion ratio (SINAD) of 83.9 dB. It consumes 45 mW of power and functions within a temperature range of -40°C to +125°C. The component is housed in a 16-pin WQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture enables simultaneous sampling for synchronized data acquisition across both inputs.
• Integrated internal reference option reduces external component count, while supporting external references for flexibility.
• Low-power SAR design achieves high throughput with minimal energy consumption suitable for battery-operated systems.
• Compact surface-mount packaging facilitates space-constrained printed circuit board layouts.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise multi-channel monitoring
• Medical instrumentation such as portable diagnostic devices
• Data acquisition modules for automated testing equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRTER corresponds to the reel packaging format when ordering. Confirm that the analog and digital supply rails match the specified voltage ranges to ensure proper operation. Check moisture sensitivity level requirements for storage and reflow soldering profiles. Ensure the WQFN-16 footprint matches the target PCB layout dimensions. Validate RoHS compliance status if required by local regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization at 14-bit resolution is required. Compare against ADS8353 if higher resolution is needed at lower speeds. Consider ADS7253 variants if different pinouts or reference configurations are preferred. Verify interface compatibility with the host microcontroller's SPI settings. Assess thermal management needs given the operating temperature range and power dissipation characteristics.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7853 series of dual-channel SAR ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7853IPW but differs in packaging and tape-and-reel configuration. The series targets applications needing moderate speed and high accuracy without complex external timing circuits.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7853IRTET is a similar variant in the same series. ADS8353IRTER offers 16-bit resolution but lower sampling rates. ADS7253 series parts provide alternative pinouts or reference options. Verify electrical parameters and package dimensions before substitution.
