ADC084S051CIMM

Analog To Digital Converters (ADC) Overview

The ADC084S051CIMM is a low-power, four-channel CMOS 8-bit analog-to-digital converter featuring a high-speed serial interface. Based on successive-approximation register architecture with an internal track-and-hold circuit, it accepts up to four input signals at pins IN1 through IN4. The device outputs straight binary data compatible with SPI, QSPI, and MICROWIRE standards. It operates on a single supply ranging from +2.7V to +5.25V, consuming 2.2 mW typ at 3V and 7.1 mW typ at 5V. Key electrical specifications include a typical DNL of ±0.09 LSB, INL of +0.12/-0.062 LSB, and SNR of 49.6 dB. It is housed in a 10-lead VSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Four Input Channels: Simultaneously handles up to four analog signals via IN1-IN4.
• Variable Power Management: Single supply operation (2.7V–5.25V) with power-down mode reducing consumption to 0.12 µW at 3V.
• High-Speed Serial Interface: Compatible with SPI, QSPI, and MICROWIRE; supports clock frequencies up to 8 MHz.
• Precision Performance: Typical DNL of ±0.09 LSB and SNR of 49.6 dB ensure accurate conversion.

• Portable Systems
• Remote Data Acquisition
• Instrumentation and Control Systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix CIMM corresponds to the 10-lead VSSOP package and industrial temperature range (-40°C to +85°C). Confirm pin compatibility if replacing existing designs, as the ADC084S051 family shares pinouts across resolutions and speeds. Ensure supply decoupling capacitors are placed within 1 cm of the VA pin for optimal performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when multi-channel 8-bit conversion is required with low power constraints. The device supports sample rates from 200 ksps to 500 ksps with full electrical specifications guaranteed over this range. Consider the ADC084S021 for lower speed requirements or the ADC084S101 for higher throughput needs, as all are pin-compatible.

Analog To Digital Converters (ADC) Part Context

The ADC084S051 belongs to the ADC084S series of 8-bit A/D converters. It is fully pin-compatible with the ADC084S021 (50–200 ksps) and ADC084S101 (500 ksps–1 Msps), allowing design flexibility without PCB layout changes. The 'CIMM' suffix denotes the specific VSSOP package variant intended for surface-mount applications.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC084S021 for lower sampling rates and the ADC084S101 for higher speeds. These devices share the same package and pinout configuration, facilitating direct substitution in existing designs requiring different throughput characteristics.
