ADS7826IDRBRG4

Analog To Digital Converters (ADC) Overview

The ADS7826IDRBRG4 is a micropower, 10-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates on a single power supply ranging from 2.7V to 5.25V and supports sampling rates up to 200ksps. The device features an external reference input and a pseudo-differential analog input stage. It communicates via a synchronous serial interface compatible with standard SPI and QSPI protocols. The component is housed in an 8-pin Small Outline No-Lead (SON) package measuring 3x3mm, designed for space-constrained applications.

Analog To Digital Converters (ADC) Feature Summary

• Micropower consumption suitable for battery-operated systems
• External voltage reference input for improved accuracy
• Pseudo-differential analog input configuration
• Standard synchronous serial interface compatibility

Analog To Digital Converters (ADC) Applications

• Portable instrumentation
• Battery-powered data acquisition systems
• Industrial process control
• Medical equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets the application requirements. Check for any specific ordering restrictions or minimum order quantities defined by the distributor. Validate that the external reference voltage aligns with the system design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution and 200ksps sampling rate are sufficient for the application. Consider the external reference requirement if high precision is needed. Evaluate the SON package size against available board space. Compare power consumption with other SAR ADCs if battery life is critical. Ensure the input voltage range matches the signal source.

Analog To Digital Converters (ADC) Part Context

The ADS7826 belongs to Texas Instruments' Micropower family of ADCs. It shares architectural similarities with the ADS7825 and ADS7827 but offers distinct resolution and speed combinations. The IDRBRG4 designation specifies the tape-and-reel packaging and RoHS-compliant variant of the ADS7826IDRBT part number.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7826IDRBT is the non-RoHS equivalent. The ADS7825 provides 8-bit resolution at similar speeds. The ADS7827 offers 8-bit resolution with higher sampling rates. Verify pinout compatibility before substitution.
