ADC084S021CIMM/J7001218

Analog To Digital Converters (ADC) Overview

The ADC084S021 is a low-power, four-channel CMOS 8-bit analog-to-digital converter featuring a high-speed serial interface. Based on a successive-approximation register architecture with an internal track-and-hold circuit, it supports sample rates from 50 ksps to 200 ksps. It operates on a single supply ranging from 2.7 V to 5.25 V, consuming 1.6 mW at 3 V and 5.8 mW at 5 V. The device provides straight binary output compatible with SPI, QSPI, and MICROWIRE standards. It includes a power-down mode reducing consumption to 0.12 µW at 3 V. The component is housed in a 10-pin VSSOP package and ensures operation within the industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm package type and tape/reel specifications. Ensure the requested part number matches the exact revision level required for your design. Confirm availability through authorized distributors as production status may change. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring multi-channel signal acquisition with moderate resolution and speed. The 8-bit resolution and up to 200 ksps throughput suit general-purpose applications where extreme precision is not critical. Consider the single-supply operation and low power draw for battery-powered designs. Verify that the serial interface timing requirements align with the host microcontroller or DSP capabilities.

Analog To Digital Converters (ADC) Part Context

The ADC084S021 belongs to Texas Instruments' family of successive-approximation register (SAR) analog-to-digital converters. It shares architectural similarities with other devices in the series, such as the ADC104S021 and ADC124S021, which offer higher resolutions. This specific model focuses on providing a cost-effective solution for 8-bit conversion tasks with integrated channel multiplexing.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the ADC104S021 for 10-bit resolution or the ADC124S021 for 12-bit resolution, maintaining similar form factors and interfaces. For lower resolution needs, the ADC084S051 offers higher sampling speeds. Ensure pin compatibility and software register mapping are verified when transitioning between these variants.
