ADC102S051CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC102S051CIMMX/NOPB is a low-power, two-channel CMOS 10-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 operates over a sample rate range of 200 ksps to 500 ksps. The device accepts a single power supply ranging from +2.7V to +5.25V, with typical power consumption of 2.7 mW at 3V and 8.6 mW at 5V. It utilizes straight binary output coding compatible with SPI, QSPI, MICROWIRE, and DSP interfaces. The component is housed in an 8-lead VSSOP package and supports operation across the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the supply voltage range aligns with system requirements for optimal noise performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion is required within a 200–500 ksps throughput limit. The device uses the analog supply voltage (VA) as the reference, so supply noise directly impacts SNR; ensure adequate decoupling with 1 µF and 0.1 µF capacitors near the VA pin. Consider pin-compatible alternatives like the ADC102S021 for lower speeds or ADC102S101 for higher speeds if specifications allow.

Analog To Digital Converters (ADC) Part Context

The ADC102S051 belongs to the Texas Instruments ADCx2S051 family of successive-approximation ADCs. It is functionally and pin-compatible with other resolutions and speeds in the series, such as the 8-bit ADC082S051 and 12-bit ADC122S051. This allows for design flexibility while maintaining board layout consistency across different resolution requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible substitutes include ADC102S021 (50–200 ksps), ADC102S101 (500 ksps–1 Msps), ADC082S051 (8-bit), and ADC122S051 (12-bit). Verify that the alternative's speed and resolution meet application needs, as electrical characteristics may differ despite physical compatibility.
