ADC14L040CIVY

The ADC14L040CIVY from Texas Instruments is a low-power, monolithic CMOS analog-to-digital converter (ADC). It is designed for high-speed data conversion, achieving 40 Megasamples per second (MSPS) with a 14-bit resolution.

This converter utilizes a differential pipeline architecture with digital error correction and an integrated sample-and-hold circuit. It offers excellent dynamic performance, including a typical Signal-to-Noise Ratio (SNR) of 74 dB and a typical Spurious-Free Dynamic Range (SFDR) of 90 dB at 10 MHz input frequency. The device operates on a single +3.3V power supply and consumes only 235 mW at its maximum conversion rate, with a power-down mode reducing consumption to 15 mW.

The ADC14L040CIVY is available in a 32-lead LQFP package and operates across an industrial temperature range of -40°C to 85°C. Its digital outputs are compatible with 2.4V to 3.6V systems, facilitating interfacing with lower voltage logic. The device supports selectable output data formats and duty cycle stabilization.

Key specifications include a 14-bit resolution, 40 MSPS sampling rate, ±0.5 LSB typical DNL, and a 150 MHz full power bandwidth. It achieves 11.9 effective bits at Nyquist.
