ADC102S051CIMM

Analog To Digital Converters (ADC) Overview

The ADC102S051CIMM is a low-power, two-channel CMOS 10-bit analog-to-digital converter featuring a high-speed serial interface. It operates over a sample rate range of 200 ksps to 500 ksps and utilizes a successive-approximation register architecture with an internal track-and-hold circuit. The device accepts a single power supply ranging from +2.7V to +5.25V, consuming 2.7 mW at 3V and 8.6 mW at 5V in normal mode. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 62.7 dB, Integral Non-Linearity (INL) of +0.2/-0.1 LSB, and Differential Non-Linearity (DNL) of ±0.13 LSB. It is housed in an 8-lead VSSOP package.

• Instrumentation and control systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'CIMM' suffix indicates the industrial temperature grade (-40°C to +85°C) and VSSOP-8 packaging configuration. Confirm that the specific revision of the datasheet matches the production lot requirements. Ensure compatibility with the host system's digital voltage levels, as inputs are referenced to VA.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion is required within a 200–500 ksps throughput window. It is suitable for applications where power efficiency is critical, offering significant reduction in consumption during idle states. Ensure the analog input range aligns with the single-supply VA pin, as the device lacks an external reference input.

Analog To Digital Converters (ADC) Part Context

The ADC102S051 belongs to Texas Instruments' S051 family of successive-approximation ADCs. It shares pin compatibility with the ADC102S021 (lower speed) and ADC102S101 (higher speed), allowing for design flexibility across different bandwidth requirements without altering the PCB layout.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC102S021 for lower speed applications and the ADC102S101 for higher throughput needs. These devices maintain identical pinouts and functional compatibility.
