ADC088S022CIMTX

Analog To Digital Converters (ADC) Overview

The ADC088S022CIMTX is a low-power, eight-channel CMOS 8-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a successive-approximation register (SAR) architecture with an internal track-and-hold circuit, supporting conversion throughput rates from 50 ksps to 200 ksps. The device features independent analog and digital power supplies, operating within a range of +2.7V to +5.25V. It accepts up to eight single-ended input signals at pins IN0 through IN7 and outputs straight binary data via a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The component is packaged in a 16-lead TSSOP form factor.

Analog To Digital Converters (ADC) Feature Summary

• Eight Input Channels: Configurable to accept up to eight single-ended analog input signals at inputs IN0 through IN7.
• Variable Power Management: Supports independent analog supply (VA) ranging from +2.7V to +5.25V and digital supply (VD) from +2.7V to VA.
• Low Power Consumption: Normal mode consumption is 0.9 mW at +3V and 5.5 mW at +5V; shutdown mode reduces power to 0.03 µW at +3V and 0.15 µW at +5V.
• Serial Interface Compatibility: Output data is straight binary and compatible with SPI, QSPI, MICROWIRE, and common DSP serial interfaces.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'CIMTX' corresponds to the tape and reel packaging variant rather than the tube version. Confirm that the specific revision level matches the design requirements, as datasheet revisions may update electrical characteristics or timing parameters. Ensure the source documentation explicitly lists this part number to avoid confusion with similar models in the family.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring multi-channel acquisition at speeds up to 200 ksps with 8-bit resolution. It is suitable for systems needing flexible power management with separate analog and digital rails. Verify that the input signal impedance is low enough to charge the sampling capacitor effectively, or add external buffering capacitors to maintain accuracy during dynamic signal sampling.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC088S022 series, which includes variants with different resolutions such as the 10-bit ADC108S022 and 12-bit ADC128S022. All members share the same pinout and operational principles but differ in resolution and performance metrics. The CIMTX designation specifically indicates the surface-mount TSSOP package with tape and reel shipping configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other members of the Texas Instruments SAR ADC family, such as the ADC108S022 for 10-bit resolution or the ADC128S022 for 12-bit resolution, provided the system can accommodate the increased data word length. Pin-compatible alternatives from other manufacturers must be verified against the specific SPI timing and voltage levels.
