Analog to Digital Converters (ADC) are the main components of data acquisition electronics. The ADC124S051CIMMX is a versatile, high-performance and low-power 12-bit analog-to-digital converter (ADC). It is designed for applications requiring high speed, precision, dynamic range, and power efficiency. This ADC is ideal for digital-processing applications and systems demanding high-speed data acquisition.

The ADC124S051CIMMX is suitable for a wide variety of applications, including medical imaging, industrial automation, automotive control, and consumer products. It utilizes a switched-capacitor-based track and hold mechanism combined with a dual sigma-delta A/D converter architecture.

The device operates using differential analog inputs, which have a wide input range, and is capable of accepting signals from ±2.5V to ±5V. The maximum sampling rate is up to 105 MHz with a 3.3V or 5V power supply. The device dissipates only 5.25mW of power when operating at 10 mVp-p differential input signals; and the IDD current is only 8.2mA.

Analog-to-Digital conversion is achieved via switched-capacitor-based track and hold circuits. In this topology, the analog signal is periodically sampled, servo-controlled and then stored on a capacitor. This capacitor holds the analog signal until acquisition is complete, allowing the analog signal to remain unchanged for the duration of the A/D conversion.

The ADC124S051CIMMX implements a dual sigma-delta A/D converter architecture where noise shaping is used to improve the dynamic range. The sampling rate and resolution of the A/D conversion are user-programmable using the SPI Configuration Interface.

The output data format is a Digital Encoder with 2 bits of extra resolution on the MSB and 6 bits of extra resolution on the LSB. The output data is digitally encoded in two’s-complement format and can be output in 12 or 14-bit resolution. The device also features an extended temperature range of -40°C to +85°C, making it suitable for a variety of applications.

The ADC124S051CIMMX is a high-performance and low-power analog-to-digital converter suitable for a wide variety of applications that require high-resolution and high-speed data acquisition. It dissipates only 5.25mW of power when operating at 10 mVp-p differential input signals, making it one of the most efficient ADC components available on the market. It offers a low-noise solution with a wide input dynamic range and extended temperature range. Furthermore, the device has a user-programmable sampling rate and output format for improved flexibility.
