ADC102S021CIMMX

Analog To Digital Converters (ADC) Overview

The ADC102S021CIMMX 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 supports sample rates from 50 ksps to 200 ksps. The device operates on a single supply ranging from +2.7V to +5.25V, consuming 1.94 mW at 3V and 6.9 mW at 5V. It includes a power-down mode reducing consumption to 0.12 µW at 3V. Packaged in an 8-lead VSSOP, it functions over the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Two input channels (IN1, IN2) with configurable multiplexing via control register bits ADD0-ADD2.
• Serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards using SCLK, CS, DIN, and DOUT pins.
• Typical Integral Non-Linearity (INL) and Differential Non-Linearity (DNL) of ±0.13 LSB.
• Signal-to-Noise Ratio (SNR) of 61.8 dB typical at 39.9 kHz input frequency.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered systems requiring low power consumption.
• Remote data acquisition networks.
• Instrumentation and control systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix CIMMX corresponds to the specific package variant and temperature grade required for the design. Confirm that the component status aligns with long-term availability needs, as older silicon revisions may have limited production runs. Ensure ESD handling protocols are followed during storage due to limited built-in protection.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel 10-bit resolution is needed with throughput up to 200 ksps. It is suitable for designs where the analog reference can be derived directly from the single power supply rail. Consider the 8-lead VSSOP package constraints if board space is limited. Verify that the host microcontroller can support the required serial clock frequencies between 0.8 MHz and 3.2 MHz.

Analog To Digital Converters (ADC) Part Context

The ADC102S021 belongs to the ADC102S family of 10-bit converters. Pin-compatible alternatives include the ADC122S021 (12-bit), ADC082S021 (8-bit), and higher-speed variants like the ADC102S051 (200-500 ksps). All devices in this table share identical pinouts and functional compatibility, allowing for easy migration between resolution or speed requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible substitutes include ADC122S021, ADC082S021, ADC102S051, and ADC102S101. These parts maintain identical pin assignments but differ in resolution or maximum sample rate specifications.
