ADC088S022CIMT

Analog To Digital Converters (ADC) Overview

The ADC088S022CIMT is an eight-channel, low-power CMOS analog-to-digital converter manufactured by Texas Instruments (originally National Semiconductor). It features a successive approximation register (SAR) architecture with an internal track-and-hold circuit. The device supports conversion throughput rates from 50 ksps to 200 ksps and provides 8-bit resolution. It accepts up to eight single-ended analog input signals via configurable multiplexers. The output data format is straight binary, compatible with standard SPI, QSPI, Microwire, and DSP serial interfaces. It operates on independent analog and digital power supplies ranging from 2.7 V to 5.25 V.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Portable battery-powered systems
• Industrial process control and monitoring
• Medical instrumentation
• Communications equipment

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC088Sxx family of 8-bit SAR ADCs. It shares architectural similarities with the ADC108S022 (10-bit) and ADC128S022 (12-bit), differing primarily in resolution. The CIMT suffix indicates a TSSOP-16 package rated for the extended industrial temperature range of -40°C to +105°C.

Analog To Digital Converters (ADC) Replacement Considerations

For higher resolution requirements, the ADC128S022CIMT/NOPB serves as a direct pin-compatible upgrade offering 12-bit performance. For lower cost or different speed profiles, verify compatibility with the ADC088S052 series.
