ADS7853IPW

Analog To Digital Converters (ADC) Overview

The ADS7853IPW is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and supports simultaneous sampling of two input channels. The device accepts pseudo-differential or single-ended inputs and features an SPI-compatible digital interface. It requires a 4.5 V to 5.5 V analog supply and a 1.65 V to 5.5 V digital supply. Key performance metrics include an SNR of 82 dB and a SINAD of 83.9 dB. The component is housed in a 16-TSSOP package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture with 1 MSPS simultaneous sampling capability
• 14-bit resolution with SAR architecture for high precision
• Flexible input configuration supporting pseudo-differential and single-ended signals
• Integrated internal reference voltage option

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Medical instrumentation such as patient monitoring devices
• Vibration analysis and acoustic testing equipment
• Data acquisition modules for automated test systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm the package type and tube packaging quantity. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for surface mount assembly processes. Ensure supply chain documentation matches the manufacturer's part number ADS7853IPW.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required at 14-bit resolution. Compare against ADS7854 if differential inputs are preferred over pseudo-differential configurations. Verify that the system power supplies align with the specified 5V analog and 1.65V-5.5V digital ranges.

Analog To Digital Converters (ADC) Part Context

The ADS7853 belongs to the ADS785x family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with the ADS7854 but differs in input type support. The IPW suffix denotes the 16-pin Thin Shrink Small Outline Package (TSSOP) variant designed for surface-mount applications.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7854IPW: Similar specifications but supports differential inputs instead of pseudo-differential/single-ended. ADS7853IRTER: Same electrical performance but utilizes a 16-WQFN package with reel/tray packaging.
