ADS7807U

Analog To Digital Converters (ADC) Overview

The ADS7807U is a low-power, 16-bit sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes successive approximation register (SAR) architecture and operates on a single 5V supply with power consumption of 28 mW. The device features a single-ended input configuration and supports both parallel and SPI serial interfaces. Key performance metrics include a maximum sampling rate of 40 kS/s, an SNR of 88 dB, and a SINAD of 88 dB. Linearity specifications are defined by a DNL of -2/3 LSB and an INL of +/- 3 LSB. It functions within an ambient temperature range of -40°C to +85°C and is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• Configurable input voltage ranges via external resistors for flexible signal interfacing
• Dual interface capability supporting both parallel data buses and standard SPI protocols
• Integrated internal reference option alongside support for external precision references

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Medical instrumentation such as ECG and patient monitoring devices
• Portable test equipment benefiting from low power consumption and 5V operation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'U' corresponds to the SOIC-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the required interface and pinout configuration for your PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications demanding 16-bit resolution at moderate sampling speeds up to 40 kS/s. It is suitable for designs constrained by a single 5V supply rail. Consider alternative parts if differential inputs or higher throughput rates are required, as this device is optimized for single-ended signals and low-power efficiency rather than high-speed multi-channel acquisition.

Analog To Digital Converters (ADC) Part Context

The ADS7807U belongs to the ADS7807 family of micro-power ADCs from Texas Instruments. This series is designed for battery-operated and space-constrained environments. The 'U' designation specifically identifies the surface-mount SOIC-28 package version, distinguishing it from other physical form factors available within the same electrical specification family.
