ADS7826IDRBT

Analog To Digital Converters (ADC) Overview

The ADS7826IDRBT is a single-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates within an analog and digital supply voltage range of 2.7 V to 5.25 V. The device supports a maximum sampling rate of 200 kSPS and utilizes a 3-wire synchronous serial interface compatible with standard SPI protocols. Housed in an 8-lead SON package measuring 3x3 mm, it features pseudo-differential inputs and requires an external reference. Key performance metrics include a power consumption of 800 µW, differential nonlinearity of ±1 LSB, integral nonlinearity of ±1 LSB, and a signal-to-noise and distortion ratio of 62 dB. It functions reliably across an industrial temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• MicroPower architecture enables low energy consumption suitable for battery-operated systems.
• Compact 8-lead SON packaging facilitates space-constrained printed circuit board layouts.
• Pseudo-differential input structure helps reduce common-mode noise effects.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low power and moderate resolution
• Industrial process control data acquisition systems
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BT' corresponds to the tape and reel packaging configuration when ordering. Confirm that the required operating temperature range aligns with the industrial grade specification (-40°C to +85°C). Ensure the design accommodates the need for an external voltage reference, as this component does not integrate an internal one. Cross-check pinout compatibility if replacing existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 10-bit resolution and 200 kSPS speed is required with minimal power usage. It is appropriate for applications where an external reference is acceptable or already present in the system. Consider the 8-lead SON package size against available board space. Compare against higher-resolution alternatives like the ADS8326 if greater precision is needed, or faster variants if throughput requirements exceed 200 kSPS.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7826 series of micro-power ADCs from Texas Instruments. It shares architectural similarities with other SAR converters in the family but is distinct in its 10-bit resolution and 200 kSPS sampling capability. The IDRBT designation specifically indicates the industrial temperature range and reel packaging format, differentiating it from other package options or commercial grade variants within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes may include other ADS7826 variants with different suffixes indicating package or temperature changes, provided the electrical characteristics remain identical. Verify functional equivalence before substitution.
