Product Overview: AD7690BRMZ-RL7

The AD7690BRMZ-RL7 is a precision 18-bit, 500 kSPS, charge redistribution analog-to-digital converter (ADC) that offers a blend of performance, power efficiency, and size, making it an ideal choice for a wide range of data acquisition systems and signal processing applications. Manufactured by Analog Devices Inc., a leader in high-performance semiconductors, this ADC is part of their renowned data converter portfolio.

Key Features

• Resolution: The AD7690 provides a high-resolution 18-bit output, ensuring detailed and accurate digital representations of the input analog signal.
• Sampling Rate: With a fast sampling rate of up to 500 kSPS (kilo-samples per second), it is well-suited for capturing high-frequency signals without significant aliasing.
• Low Power Consumption: Designed for power-sensitive applications, it features low power operation, consuming only 2.3 mW at the full 500 kSPS rate, which drops to 1 µW in power-down mode.
• Pseudo-Differential Input: The pseudo-differential input structure allows for the reduction of common-mode noise, which is beneficial in noisy environments or when long signal traces are necessary.
• No Pipeline Delay: The ADC operates without pipeline delay, also known as latency, which is crucial for control-loop applications and systems requiring real-time data processing.
• Interface: A serial interface compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards, provides flexible and straightforward integration into system designs.
• Packaging: The AD7690BRMZ-RL7 is offered in a compact 10-lead MSOP (Mini Small Outline Package), which is advantageous for space-constrained applications.
